    BUSKER v. WABTEC CORPORATION
    S251135
    Opinion of the Court by Corrigan, J.
    California’s prevailing wage law (Lab. Code, 1 § 1720 et
    seq.) is a minimum wage provision that generally applies to
    those employed on “public works.” This case involves two
    questions: (1) Does publicly funded work on rolling stock, like
    train cars, fall under the statutory definition of “public works”?
    (2) Alternatively, does the work on rolling stock in this case
    qualify as “public work” because it is integral to other activity
    that itself qualifies as public work? The answer to both
    questions is no.
    I. BACKGROUND
    The Southern California Regional Rail Authority operates
    a large train system known as Metrolink. In 2010, it entered
    into the prime contract with Parsons Transportation Group, Inc.
    (Parsons) to design, furnish, and install a comprehensive
    communications network called Positive Train Control (PTC) to
    prevent collisions and other dangerous train movement.
    The project was publicly funded and cost over $216
    million. The expansive undertaking included wayside signals,
    systems on locomotives and rail cars, back office servers, a
    communications network, and a centralized dispatching system,
    along with software development and installation. The system
    required integration of various components located on trains, at

    Opinion of the Court by Corrigan, J.
    wayside sites along tracks, and at centralized control centers.
    While the undertaking was done under a public contract, not all
    aspects of the enterprise necessarily qualify as a public work.
    “Public works” is a term of art defined by statute.2 (See § 1720
    et seq.)
    Only two aspects of the project are at issue here: field
    work and onboard work.3 Field work included building and
    outfitting radio towers on land adjacent to train tracks. The
    labor required trenching, driving forklifts, operating cranes, and
    welding. Onboard work primarily involved installing electronic
    components on the train cars and locomotives themselves.
    Defendant Wabtec Corporation (Wabtec) subcontracted to
    install system components on locomotives and rail cars. The
    subcontract incorporated various provisions of the prime
    contract, including compliance with applicable prevailing wage
    laws. Wabtec performed no field work.
    Plaintiff John Busker was one of over 100 Wabtec workers
    assigned to the project. For approximately two years, he did
    traditional electrical onboard installation. Wabtec did not pay
    prevailing wages to any of its employees.
    Busker filed a prevailing wage complaint against Wabtec
    with the Division of Labor Standards Enforcement (DLSE), a
    division of the Department of Industrial Relations (Department)
    2
    The prevailing wage law uses the plural term “public works”
    as well as the singular term “public work.” (See §§ 1720, subd.
    (a)(1) & (2), 1770, 1771, 1772.) This opinion uses the terms
    interchangeably.
    3
    Field work is referred to as “field installation work” in the
    contract. This opinion uses the abbreviated term to avoid
    unnecessary repetition.
    2
    BUSKER v. WABTEC CORPORATION
    Opinion of the Court by Corrigan, J.
    that enforces California’s labor laws. (See Alvarado v. Dart
    Container Corp. of California (2018) 
    4 Cal.5th 542
    , 555.) In
    2015, the DLSE issued a civil wage and penalty assessment of
    $6,468,564 against Wabtec for failure to pay prevailing wages.4
    Wabtec requested review by the Labor Commissioner, arguing
    that the prevailing wage law does not apply to the onboard work
    because the law covers only work performed on or to real
    property, not “rolling stock”5 like locomotives and buses.
    After review, the DLSE vacated the assessment and took
    no further action. In this case, a DLSE officer testified his
    superior directed him to vacate the assessment because,
    historically, work performed on rolling stock is not covered by
    the prevailing wage law. The Department never formally
    determined whether the prevailing wage law covers onboard
    work.
    While the review of the assessment was pending, Busker
    sued Wabtec and the project manager 6 in state court for failing
    4
    The assessment consisted of $5,786,349 in wages due plus
    related penalties of $682,215. The assessment order did not
    contain any factual or legal basis for the DLSE’s finding, aside
    from spreadsheets containing the wage and penalty
    calculations.
    5
    The prevailing wage law does not mention “rolling stock.”
    Black’s Law Dictionary defines the term as “[m]ovable property,
    such as locomotives and rail cars, owned by a railroad.” (Black’s
    Law Dict. (11th ed. 2019) p. 1592, col. 1.) In the federal “Buy
    America” regulations, rolling stock has a much broader
    definition that includes “buses, vans, cars, railcars, locomotives,
    trolley cars and buses, and ferry boats, as well as vehicles used
    for support services.” (
    49 C.F.R. § 661.3
     (2021).) This opinion
    uses the term broadly to encompass all types of conveyances.
    6
    We refer to the defendants collectively as Wabtec.
    3
    BUSKER v. WABTEC CORPORATION
    Opinion of the Court by Corrigan, J.
    to pay prevailing wages. Wabtec removed the action to federal
    district court and sought summary judgment urging Wabtec’s
    onboard work was not subject to prevailing wage requirements.
    The court granted the motion, reasoning that only workers
    “employed on [a] project involving fixed works or realty” are
    entitled to prevailing wages. It also rejected Busker’s other
    argument that the onboard work fell within the scope of the
    prevailing wage law under section 1772 as work done “in the
    execution” of the overall project to install the PTC system. The
    court concluded that section 1772 still requires the applicable
    contract to be one for “public work,” and the Wabtec subcontract,
    limited to rolling stock, did not qualify.
    Busker appealed and we accepted a request from the
    United States Court of Appeals for the Ninth Circuit to decide a
    question of state law. (Cal. Rules of Court, rule 8.548(a).) That
    court posed the question as follows: “Whether work installing
    electrical equipment on locomotives and rail cars (i.e., the ‘on-
    board work’ for Metrolink’s PTC project) falls within the
    definition of ‘public works’ under California Labor Code
    § 1720(a)(1) either (a) as constituting ‘construction’ or
    ‘installation’ under the statute or (b) as being integral to other
    work performed for the PTC project on the wayside (i.e., the
    ‘field installation work’).”
    II. DISCUSSION
    A.     Overview of California’s Prevailing Wage Law
    Economic conditions in the Great Depression prompted
    the passage of prevailing wage laws designed to ensure that
    workers employed on public building programs would be paid
    daily wages commensurate with those prevailing in the local
    area for work of a similar character. (See Universities Research
    4
    BUSKER v. WABTEC CORPORATION
    Opinion of the Court by Corrigan, J.
    Assn. v. Coutu (1981) 
    450 U.S. 754
    , 773–774; Azusa Land
    Partners v. Department of Industrial Relations (2010) 
    191 Cal.App.4th 1
    , 14–15.) The goal was to give local contractors
    and labor a fair opportunity to work on public building projects
    that might otherwise be awarded to contractors who hired
    cheaper out-of-market labor. (Universities Research Assn. v.
    Coutu, at p. 774.)
    The prevailing wage law was enacted in 1931 as an
    uncodified measure. (1931 Act; Stats. 1931, ch. 397, p. 910.) A
    federal counterpart, the Davis-Bacon Act, was enacted the same
    year. (
    40 U.S.C. § 3141
     et seq.) In 1937, California’s prevailing
    wage law was codified as part 7 of the newly established Labor
    Code. (Stats. 1937, ch. 90, pp. 185, 241.)
    “The overall purpose of the prevailing wage law is to
    protect and benefit employees on public works projects.”
    (Lusardi Construction Co. v. Aubry (1992) 
    1 Cal.4th 976
    , 985
    (Lusardi).) “This general objective subsumes within it a number
    of specific goals: to protect employees from substandard wages
    that might be paid if contractors could recruit labor from distant
    cheap-labor areas; to permit union contractors to compete with
    nonunion contractors; to benefit the public through the superior
    efficiency of well-paid employees; and to compensate nonpublic
    employees with higher wages for the absence of job security and
    employment benefits enjoyed by public employees.” (Id. at
    p. 987.) Courts liberally construe the law to fulfill its purpose.
    (City of Long Beach v. Department of Industrial Relations (2004)
    
    34 Cal.4th 942
    , 949–950 (City of Long Beach).)
    Generally, those employed on public works must be paid
    at least the prevailing rate of per diem wages paid locally for
    5
    BUSKER v. WABTEC CORPORATION
    Opinion of the Court by Corrigan, J.
    work of a similar character.7 (§ 1771.) A contractor or
    subcontractor that does not pay the prevailing rate is liable for
    the deficiency and subject to a penalty. (§ 1775.) The obligation
    to pay prevailing wages has a statutory basis independent of any
    contractual requirement. (Lusardi, 
    supra,
     1 Cal.4th at pp. 981–
    982.) A contractor must pay prevailing wages when required,
    even if it has not contractually agreed to do so. (Id. at p. 988.)
    B.    Onboard Work as “Construction” or “Installation”
    Under Section 1720, Subdivision (a)(1)
    The first question is whether the onboard work done
    exclusively on locomotives and rail cars (rolling stock) falls
    under the definition of “public work.” An examination of the
    relevant statute establishes that it does not.
    The prevailing wage law has its roots in the Depression
    Era. Then, as now, when a governmental entity decided to build
    a courthouse in the town square, a great many aspects of that
    project would come into play. Architects in Los Angeles might
    devise the plans. Lawyers in San Francisco might draft the
    contracts. But when it came time to excavate the basement, lay
    the foundation, and raise the walls, local daily wage workers
    would be hired to do the work. It was their livelihood that the
    7
    Prevailing wage requirements do not apply to work carried out
    by a public agency with its own labor force or to projects with a
    dollar value of $1,000 or less. (§ 1771.) A public entity
    “awarding any contract of public work, or otherwise undertaking
    any public work,” must obtain the local prevailing rate for each
    craft, classification, or type of worker needed to execute the
    contract. (§ 1773.) The applicable wage rates must be included
    in the call for bids, in bid specifications, and in the contract or,
    alternatively, those documents must specify that the rates are
    on file in the public entity’s principal office. (§ 1773.2.)
    6
    BUSKER v. WABTEC CORPORATION
    Opinion of the Court by Corrigan, J.
    prevailing wage law was designed to protect and enhance. In
    the decades since, the law has been amended a number of times
    to include or exclude certain kinds of work. It has never been
    modified to embrace work on rolling stock.
    The term of art “public works” is defined in section 1720,
    subdivision (a), which begins by providing, “[a]s used in this
    chapter, ‘public works’ means: . . . .” It then sets out eight
    numbered subdivisions that define the term in various contexts.
    (§ 1720, subd. (a)(1)–(8).) The operative definition here is found
    in section 1720, subdivision (a)(1) (hereafter section 1720(a)(1)).8
    Under section 1720(a)(1), “public works” means
    “[c]onstruction, alteration, demolition, installation, or repair
    work done under contract and paid for in whole or in part out of
    public funds . . . .”9 There are three basic elements to a “public
    work” under section 1720(a)(1): (1) “construction, alteration,
    8
    See, e.g., other subdivisions that involve irrigation systems,
    but not their operation (§ 1720, subd. (a)(2)); some street and
    sewer improvements (§ 1720, subd. (a)(3)); laying of carpet
    (§ 1720, subd. (a)(4) & (a)(5)); and tree removal (§ 1720, subd.
    (a)(8)).
    9
    Subdivision (a)(1) of section 1720 also contains an exception
    not relevant here and then goes on to discuss the scope of the
    terms “construction” and “installation,” as follows:        “For
    purposes of this paragraph, ‘construction’ includes work
    performed during the design, site assessment, feasibility study,
    and other preconstruction phases of construction, including, but
    not limited to, inspection and land surveying work, regardless
    of whether any further construction work is conducted, and
    work performed during the postconstruction phases of
    construction, including, but not limited to, all cleanup work at
    the jobsite. For purposes of this paragraph, ‘installation’
    includes, but is not limited to, the assembly and disassembly of
    freestanding and affixed modular office systems.”
    7
    BUSKER v. WABTEC CORPORATION
    Opinion of the Court by Corrigan, J.
    demolition, installation, or repair work”; (2) that is done under
    contract; and (3) is paid for in whole or in part out of public
    funds. (Ibid.) Busker argues that the onboard work fell under
    this definition as either “construction” or “installation.” It is
    undisputed that the work was done under contract and paid for
    with public money.
    Familiar principles guide our interpretation of section
    1720(a)(1).    Our fundamental task is to determine the
    Legislature’s intent to effectuate the law’s purpose, giving the
    statutory language its plain and commonsense meaning. We
    examine that language, not in isolation, but in the context of the
    statutory framework as a whole to discern its scope and purpose
    and to harmonize the various parts of the enactment. (Coalition
    of Concerned Communities, Inc. v. City of Los Angeles (2004) 
    34 Cal.4th 733
    , 737.) “If the language is clear, courts must
    generally follow its plain meaning unless a literal interpretation
    would result in absurd consequences the Legislature did not
    intend. If the statutory language permits more than one
    reasonable interpretation, courts may consider other aids, such
    as the statute’s purpose, legislative history, and public policy.”
    (Ibid.) The wider historical circumstances of a law’s enactment
    may assist in ascertaining legislative intent, supplying context
    for otherwise ambiguous language. (See California Mfrs. Assn.
    v. Public Utilities Com. (1979) 
    24 Cal.3d 836
    , 844.)
    While neither “construction” nor “installation” is explicitly
    defined in the prevailing wage law, City of Long Beach
    considered various definitions of the term “construction.” (City
    of Long Beach, 
    supra,
     34 Cal.4th at p. 951.) Those include “ ‘the
    action of framing, devising, or forming, by putting together of
    parts; erection, building’ ” (ibid., quoting 3 Oxford English Dict.
    (2d ed. 1989) p. 794) and “ ‘[t]he act of putting parts together to
    8
    BUSKER v. WABTEC CORPORATION
    Opinion of the Court by Corrigan, J.
    form a complete integrated object.’ ” (City of Long Beach, at p.
    951, quoting Webster’s 3d New Internat. Dict. (2002) p. 489, col.
    2.) Because neither definition confines the term “construction”
    to the building of a structure, onboard work could arguably fall
    within these definitions.
    Similarly, dictionary definitions of “installation” do not
    limit that activity to a fixed work on real property. Webster’s
    Third New International Dictionary defines one sense of
    “installation” as “the setting up or placing in position for service
    or use.” (Webster’s 3d New Internat. Dict., supra, at p. 1171,
    col. 1.) That broad definition could conceivably encompass
    onboard work.
    However, words used in a statute are not considered in
    isolation. They are construed in context, honoring the statutory
    purpose, and harmonizing statutes relating to the same subject
    to the extent possible. (Dyna-Med, Inc. v. Fair Employment &
    Housing Com. (1987) 
    43 Cal.3d 1379
    , 1387.) Here, the general
    terms “construction” and “installation” are offered as categories
    of “public works,” a term which itself has a generally understood
    meaning that substantially predates the prevailing wage law. It
    is that definition that gives context to the Legislature’s use of
    the terms construction and installation.
    Dictionary definitions dating back to the turn of the 20th
    century uniformly define “public works” as fixed works on real
    property. The term is defined in a 1906 edition as “all fixed
    works constructed for public use, as railways, docks, canals,
    9
    BUSKER v. WABTEC CORPORATION
    Opinion of the Court by Corrigan, J.
    water-works, roads, etc.”10 (6 Century Dict. & Cyclopedia (1906)
    p. 4830, col. 2.)
    The 1925 edition of California Jurisprudence, published in
    the decade before the prevailing wage law enactment, observed:
    “The term ‘public works’ may be said to embrace all fixed works
    constructed for public use or protection. . . . In view of the acts
    authorizing public improvements the term probably includes
    bridges, waterworks, sewers, light and power plants, public
    buildings, wharves, breakwaters, jetties, seawalls, schoolhouses
    and street improvements.” (22 Cal.Jur. (1925) Public Works, §2,
    pp. 74–75, fn. omitted.) Swanton v. Corby (1940) 
    38 Cal.App.2d 227
    , 230, relied upon this definition to hold that installing a two
    -way police radio system did not constitute a public work within
    the meaning of a law requiring competitive bidding. There, the
    relevant statutory scheme applied to the “ ‘erection,
    improvement, and repair of all public buildings and works
    . . . .’ ” (Id. at p. 229.) The court concluded the radio system was
    analogous to “furniture and furnishings,” which had “never been
    held to be ‘public works.’ ” (Id. at p. 230.) While Swanton did
    not involve the prevailing wage law, it did rely on the
    established common understanding of public works to interpret
    the otherwise undefined terms “ ‘erection, improvement, and
    repair’ ” as work associated with fixed works on real property.
    (Id. at p. 229.)
    10
    More recently, in the 2002 edition of Webster’s Third New
    International Dictionary, “public works” is defined as “fixed
    works (as schools, highways, docks) constructed for public use or
    enjoyment . . . .” (Webster’s 3d New Internat. Dict., supra, p.
    1836, col. 3.)
    10
    BUSKER v. WABTEC CORPORATION
    Opinion of the Court by Corrigan, J.
    Busker does not dispute that dictionary definitions of
    public works refer to fixed works on realty. But he claims those
    definitions are irrelevant, citing the principle that a court
    should not rely on a dictionary definition of a term specifically
    defined in the statute. (See Hammond v. Agran (1999) 
    76 Cal.App.4th 1181
    , 1189.) That principle is valid but does not
    assist here. The dictionary definitions of “public works” are not
    offered in lieu of a statutory definition. Instead, they provide
    context to the terms “construction” and “installation” used in the
    statute to generally describe kinds of public works. While
    section 1720(a)(1) has been amended over the years to include
    examples of “construction” and “installation,” nowhere does it
    provide a general definition of the terms, which could have very
    broad meanings if context is ignored.              For example,
    “construction” might be considered to include the building of a
    public ferry boat; “installation” might be conceived as
    downloading software; “alteration” could be read to include
    clothing modification; and “repair” might be applied to
    overhauling a bus. Nothing in standard dictionary definitions
    would preclude those interpretations. However, “ ‘ “words have
    no meaning apart from the world in which they are spoken.” ’ ”
    (State of California v. Altus Finance (2005) 
    36 Cal.4th 1284
    ,
    1296.) The words say what they say: their meaning is
    understood from the context in which they are used.
    An examination of the original enactment and later
    codification of the prevailing wage law provides that context. As
    originally enacted, the prevailing wage law said only that
    certain “construction or repair work . . . shall be held to be
    ‘public works’ within the meaning of this act.” (Stats. 1931, ch.
    397, § 4, p. 912.) The original prevailing wage law did not
    include the terms “alteration,” “demolition,” or “installation.”
    11
    BUSKER v. WABTEC CORPORATION
    Opinion of the Court by Corrigan, J.
    But the original statutory language did help illustrate the scope
    of public works. In referring to the relevant “locality” for
    determining the prevailing wage rate, it defined “ ‘locality’ ” as
    the “city and county, county or counties in which the building,
    highway, road, excavation, or other structure, project,
    development or improvement is situated . . . .” (Stats. 1931, ch.
    397, § 4, p. 912, italics added.) The italicized words suggest that
    the term “public works” was limited to fixed works situated on
    or attached to land.11 In that context, “construction” and
    “repair” under the law’s original enactment appear limited to
    labor performed on fixed works.
    The prevailing wage law, codified in 1937, continued to
    apply to specified “[c]onstruction or repair work.” (§ 1720, subd.
    (a), as enacted by Stats. 1937, ch. 90, p. 241.) However, the
    definition of “locality” for rate determination was simplified to
    refer to the “county in which the public work is done.” (§ 1724,
    as enacted by Stats. 1937, ch. 90, p. 241.) While the omission of
    11
    Although the term “project” might be interpreted more
    broadly, it is part of a list of terms that would generally be
    understood to be limited to fixed works. Under the principle of
    “noscitur a sociis (it is known by its associates) ‘. . . a court will
    adopt a restrictive meaning of a listed item if acceptance of a
    more expansive meaning would make other items in the list
    unnecessary or redundant, or would otherwise make the item
    markedly dissimilar to other items in the list.’ ” (People ex rel.
    Lungren v. Superior Court (1996) 
    14 Cal.4th 294
    , 307.) To
    interpret “project” as something other than a fixed work would
    render that term markedly different from the other listed items.
    The noscitur a sociis principle, like other canons of statutory
    construction, is merely an aid in ascertaining legislative intent.
    (See People v. Garcia (2016) 
    62 Cal.4th 1116
    , 1124.) While its
    application does not compel an interpretation of “project” that is
    limited to fixed works, it nevertheless supports giving the term
    that more restricted meaning.
    12
    BUSKER v. WABTEC CORPORATION
    Opinion of the Court by Corrigan, J.
    terms like “building” or “road” in the definition of “locality” could
    potentially suggest an intent to broaden the scope of “public
    works,” nothing else in the 1937 legislation would support such
    a conclusion. The codified provision did not substantively
    change the definition of “construction” and “repair” as types of
    “public works.” (Compare Stats. 1931, ch. 397, § 4, p. 912 with
    § 1720, subd. (a) as enacted by Stats. 1937, ch. 90, p. 241.)
    Indeed, the Legislature gave no indication it intended to
    confer on the terms “construction” or “repair” a more expansive
    meaning when it codified the existing law. If the Legislature
    had intended such a departure from the well-established
    understanding of the term “public work,” one would expect that
    intent to be reflected in the statutory history, rather than
    requiring divination from a simple modification to an ancillary
    provision. (See Garcia v. McCutchen (1997) 
    16 Cal.4th 469
    ,
    482.) In fact, the legislative history points to a contrary
    conclusion.     In 1936, the California Code Commission
    (Commission) prepared a Proposed Labor Code for the
    Legislature’s consideration. In a note to proposed section 1720,
    the Commission explained that its draft of section 1720,
    subdivision (a) was taken “verbatim” from the analogous
    construction and repair provision in the original 1931 Act. (Cal.
    Code Com. note, Proposed Labor Code (1936), foll. § 1720, p. 85.)
    It is reasonable to conclude, then, that the ultimate codification
    reflected the Legislature’s intent to embrace the established
    understanding of the term “public work” as the context in which
    the terms construction and repair were used.
    Nevertheless,    Busker     claims    that    subsequent
    amendments establish that the Legislature sought to give
    “public works” a broader connotation than the original common
    usage. He notes that a 2000 amendment to section 1720(a)(1)
    13
    BUSKER v. WABTEC CORPORATION
    Opinion of the Court by Corrigan, J.
    included preconstruction work within the definition of
    “construction.” He argues this amendment “evidences . . . the
    Legislature’s intent to give ‘construction’ a broad meaning,”
    citing Oxbow Carbon & Minerals, LLC v. Department of
    Industrial Relations (2011) 
    194 Cal.App.4th 538
    , 549 (Oxbow).
    The amended language specified that “ ‘construction’ includes
    work performed during the design and preconstruction phases
    of construction including, but not limited to, inspection and land
    surveying work.” (§ 1720, former subd. (a), as amended by
    Stats. 2000, ch. 881, § 1, p. 6517.) While the 2000 legislation
    may have enlarged the scope of “construction” to include the
    design and preconstruction phases of a construction project, it
    did not purport to change the settled understanding of the term
    “public work” to cover activity divorced from fixed works on real
    property. As Oxbow itself recognized, the legislation did not
    purport to define construction but merely explained the scope of
    the term.12 (Oxbow, at p. 548.)
    Nothing in the 2000 amendment signals an intent to
    uncouple the term “construction” from the context of “public
    work.”      The examples of work that are included in
    “construction,” like land surveying, are consistent with a
    definition of “construction” related to land-based activity. The
    legislative history of the 2000 amendment confirms that it was
    12
    In 2014, the scope of “construction” in section 1720(a)(1) was
    again amended to encompass “work performed during the
    postconstruction phases of construction, including, but not
    limited to, all cleanup work at the jobsite.” (Legis. Counsel’s
    Dig., Assem. Bill No. 26, Stats. 2014, ch. 864, italics added.)
    Like the 2000 amendment, the statutory language clarifying
    that postconstruction work falls within the scope of section
    1720(a)(1) does not change the fundamental understanding of
    what public work “construction” entails.
    14
    BUSKER v. WABTEC CORPORATION
    Opinion of the Court by Corrigan, J.
    intended to reflect the Department’s existing practice of
    including “construction inspectors and land surveyors among
    those workers deemed to be employed upon public works . . . .”
    (Sen. Com. on Labor & Employment, 3d reading analysis of Sen.
    Bill No. 1999 (1999–2000 Reg. Sess.) as amended Aug. 23, 2000,
    p. 2.)
    Busker also contends that the 2001 addition of the word
    “installation” to section 1720(a)(1) signaled an intent to broaden
    the scope of that section. Again, the legislative history suggests
    otherwise. The purpose of the legislation was to codify then-
    existing interpretations by the Department treating installation
    of fixtures on real property as part of the construction process.
    (Cal. Dept. of Industrial Relations, Enrolled Bill Rep. on Sen.
    Bill No. 975 (2001–2002 Reg. Sess.) prepared for Governor Davis
    (Sept. 20, 2001), p. 2.) The Legislature was concerned that a
    future administration might “rescind the [Department’s]
    precedential determinations” and exclude installation work as
    not “ris[ing] to the level of construction . . . .” (Id., p. 3.) Thus,
    the addition of “installation” to section 1720(a)(1) should not be
    interpreted as expanding the scope of public works to rolling
    stock. Instead, it was merely intended to confirm that the
    installation of fixtures on land is part of the “construction”
    process.
    In 2012, the Legislature again amended section 1720(a)(1)
    to clarify that “[f]or purposes of this paragraph, ‘installation’
    includes, but is not limited to, the assembly and disassembly of
    freestanding and affixed modular office systems.” (Stats. 2012,
    ch. 810, § 1.) Seizing upon the reference to “freestanding”
    systems, Busker contends the Legislature has rejected the
    notion that an “installation” must involve “fixed works or work
    that is ‘affixed’ or ‘bolted’ to realty . . . .” Busker reads too much
    15
    BUSKER v. WABTEC CORPORATION
    Opinion of the Court by Corrigan, J.
    into the amendment. The change was enacted to overrule a
    specific line of Department decisions that treated the assembly
    or disassembly of modular office systems as “installation” work
    only if the systems were bolted, secured, or otherwise mounted
    to real property. (Assem. Com. on Labor & Employment,
    Analysis of Assem. Bill No. 1598 (2011–2012 Reg. Sess.) as
    introduced Feb. 6, 2012, p. 2.) The legislative history explains
    that the process of assembling freestanding office systems, like
    cubicles, involves work analogous to installing modular walls
    secured to a structure. (Id. at p. 3.) The legislation sought to
    eliminate what was viewed as an unwarranted distinction
    between fixed and freestanding modular office systems. The
    amendment was limited to that aim. Even after the 2012
    amendment, aside from modular office systems, the Department
    continues to apply the rule that “installation” means “bolting,
    securing or mounting of fixtures to realty.”13
    In his dissent, Justice Liu argues that modular office
    systems are like rolling stock in that they “can be easily moved
    and transported to other locations.” (Dis. opn. of Liu, J., post, at
    p. 8.) However, there is no indication that the moveable aspect
    of modular office systems motivated the amendment to section
    1720(a)(1). The Legislature’s focus was on the nature of the
    work that takes place in a structure, not on the fact the office
    systems could be easily moved. Regardless of whether a
    modular system is fixed or freestanding, it remains the case that
    13

    16
    BUSKER v. WABTEC CORPORATION
    Opinion of the Court by Corrigan, J.
    office systems are installed in buildings. The work takes place
    in a fixed structure on land. The same is not true of installation
    performed on train cars. Nothing in the 2012 amendment
    suggests the Legislature sought to include rolling stock. If the
    Legislature had intended the statute to broadly cover all
    installation projects beyond those on real property, it could have
    easily said so.
    Busker contends that if the Legislature intended “public
    works” to refer exclusively to construction projects involving
    fixed works on realty, it knew how to do so. He points to
    Government Code section 4002, which defines “ ‘public work’ ”
    for purposes of record-keeping requirements to mean “the
    construction of any bridge, road, street, highway, ditch, canal,
    dam, tunnel, excavation, building or structure . . . .” He also
    cites Public Contract Code section 1101, which defines “ ‘[p]ublic
    works contract’ ” as “an agreement for the erection,
    construction, alteration, repair, or improvement of any public
    structure, building, road, or other public improvement of any
    kind.” According to Busker, the fact that the Legislature defined
    “public work” to mean only certain construction projects on real
    property in the Government and Public Contract Codes shows
    that it did not intend a similar meaning in section 1720(a)(1),
    which omits any reference to fixed works or real property. The
    contention fails.
    Busker relies on the principle that “ ‘when different words
    are used in contemporaneously enacted, adjoining subdivisions
    of a statute, the inference is compelling that a difference in
    meaning was intended.’ ” (Kleffman v. Vonage Holdings Corp.
    (2010) 
    49 Cal.4th 334
    , 343.) That principle is inapplicable here.
    The definitions he cites are not contained in subdivisions that
    adjoin section 1720(a)(1) or even in neighboring statutes in the
    17
    BUSKER v. WABTEC CORPORATION
    Opinion of the Court by Corrigan, J.
    Labor Code. Instead, they are found in entirely separate codes.
    They were also not enacted contemporaneously with the
    statutory language at issue here. Public Contract Code section
    1101 was enacted in 1982. (Stats. 1982, ch. 1120, § 3, p. 4046.)
    Government Code section 4002’s record-keeping provisions
    derive from an uncodified statute enacted in 1923. (Stats. 1923,
    ch. 448, § 1, p. 1053.) The inference Busker seeks to draw is
    unsupported.
    There is no reason to believe the Legislature deliberately
    defined “public works” in the prevailing wage law to distinguish
    it from definitions contained in other codes enacted at different
    times. Instead of suggesting by implication that “public works”
    as used in the prevailing wage law is broad enough to encompass
    rolling stock, the definitions contained in the Government Code
    and Public Contract Code tend to confirm the common
    understanding that “public works” generally refers to fixed
    works on real property.
    Indeed, within the prevailing wage law, the Legislature
    defined “ ‘[p]ublic works project’ ” in section 1750, subdivision
    (b)(1) to mean “the construction, repair, remodeling, alteration,
    conversion, modernization, improvement, rehabilitation,
    replacement, or renovation of a public building or structure.”
    (Italics added.) The definition is limited to fixed works. Section
    1750 speaks to a narrow circumstance to authorize a private
    right of action by the second lowest bidder on a public works
    project when the successful bid was premised upon a violation
    of the law for which the successful bidder was convicted.
    (§ 1750, subd. (a)(1).) The definition of “ ‘[p]ublic works project’ ”
    in the narrow context of section 1750 was enacted long after the
    1930’s codification of the Labor Code. Nevertheless, it tends to
    demonstrate that the term “public works” as used in the
    18
    BUSKER v. WABTEC CORPORATION
    Opinion of the Court by Corrigan, J.
    prevailing wage law is still generally confined to work on
    buildings or other structures. The Legislature may, of course,
    define “public works” more broadly. But there is nothing to
    suggest the Legislature has thus far intended to expand the
    term as used in section 1720(a)(1) beyond fixed works on land.
    The New York case of De La Cruz v. Caddell Dry Dock &
    Repair Co. (2013) 
    21 N.Y.3d 530
     (De La Cruz) declined to employ
    the common understanding that “public works” is limited to
    labor on land. (See dis. opn. of Liu, J., post, at p. 5.) However,
    the particular state law it applied was worded and structured
    differently from California’s statutory scheme. De La Cruz held
    that New York’s law covers work performed on various boats
    used for public purposes. (De La Cruz, at pp. 538–539.) The
    New York court’s holding is, of course, not binding. Further, its
    analysis provides no assistance.
    First, unlike California’s law, which limits the definition
    of “public works” to defined categories like construction and
    installation (see § 1720 et seq.), New York’s prevailing wage
    scheme contains no definition of “public works.” (See N.Y. Labor
    Law, § 220(3).) New York’s law is unique in this respect.
    (Johnson, Prevailing Wage Legislation in the States (Aug. 1961)
    84:
    8 Monthly Lab. Rev. 839
    , 841.) Confronted with a statute
    that did not define the term, the New York court created a three-
    pronged test to assess whether a project is subject to prevailing
    wage requirements. (De La Cruz, 
    supra,
     21 N.Y.3d at p. 538.)
    Under the De La Cruz test, New York’s law may apply if the
    “project . . . primarily involves construction-like labor . . . .”
    (Ibid, italics added.) This definition, focusing not on the specific
    labor but the project for which it is done, sweeps more broadly
    than the expressly defined categories of “public works” in
    California’s prevailing wage law. Further, the New York court
    19
    BUSKER v. WABTEC CORPORATION
    Opinion of the Court by Corrigan, J.
    focused on its statutory scheme and state constitution, which
    specified that the applicable prevailing wage is based on the
    locality where the “ ‘public work is to be situated, erected or
    used.’ ” (Id. at p. 535, some italics omitted.) Whereas a boat
    used for a public purpose would not be described as “ ‘erected,’ ”
    the court observed that the terms “ ‘situated’ ” and “ ‘used’ ”
    could apply. (Ibid.) There is no similar language in California’s
    statute defining the locality in which public work is performed.14
    (See § 1724.)
    De La Cruz also purported to rely on federal authority
    detaching the understanding of “public works” from work on
    land.15 (De La Cruz, 
    supra,
     21 N.Y.3d at p. 535.) It pointed to a
    case decided more than a century earlier in which the United
    States Supreme Court concluded it was not bound to read the
    term “ ‘public work’ ” as “confined to work on land.”            (Title
    14
    It will be recalled that California’s 1937 codification omitted
    the previous use of the term “project” in describing the locality
    in which the work is done. (See ante, at pp. 12–13; § 1724.)
    15
    De La Cruz reviewed dictionary definitions of “ ‘public works’ ”
    from 1891 to 2013. It observed that “illustrative examples given
    in dictionary entries are frequently fixed structures . . . .” (De
    La Cruz, 
    supra,
     21 N.Y.3d at p. 538.) The court went on to opine:
    “[I]t is clear that the notion that a ‘public work’ must be attached
    to the land is not part of [the] central meaning” of the term.
    (Ibid.) However, all of the illustrative examples in the
    dictionary entries quoted in Del La Cruz are fixed works:
    “ ‘[s]tructures (such as road or dams),’ ” “ ‘public buildings,
    roads, aqueducts, parks, etc.,’ ” “ ‘roads, railways, bridges, etc.,’ ”
    and “ ‘schools, highways, docks.’ ” (Id. at p. 537.) De La Cruz
    relegated to a footnote a definition that explicitly incorporates
    “ ‘fixed’ ” in the definition of “public works.” (Id. at p. 538, fn. 5.)
    The dictionary definitions cited in De La Cruz support rather
    than undermine the common understanding that “public works”
    is generally limited to fixed works on real property.
    20
    BUSKER v. WABTEC CORPORATION
    Opinion of the Court by Corrigan, J.
    Guaranty & Trust Co. of Scranton v. Crane Co. (1910) 
    219 U.S. 24
    , 33.) This reliance is tenuous. Crane did not involve a
    question of prevailing wage entitlement.            Aside from
    acknowledging that “public works usually are of a permanent
    nature,” Crane focused solely on the meaning of the word
    “public.” (Ibid.) These points distinguish De La Cruz from the
    question we encounter. An interpretation that considers the
    history of California’s prevailing wage law along with the
    historical meaning of “public works” supports an interpretation
    that generally limits the term to labor performed on fixed works.
    This interpretation is confirmed in determinations made
    by the Department, which has consistently excluded work on
    rolling stock. For example, in a 1990 coverage determination,
    the Department’s director concluded that the repair of police
    boats was not a public work, reasoning that the term has been
    construed “as having a restricted meaning as applying to work
    done on fixed works for public use or production.” (Dept. of
    Industrial Relations, Director Ron Rinaldi, letter to Port of San
    Diego Section Chief Kenneth E. White, June 26, 1990.)
    Similarly, in 1994, a public agency sought prevailing wage
    determinations for contracts involving ship repairs.           The
    Department “determined, consistent with previous court rulings
    and opinions from the Attorney General’s Office, that
    maintenance/repair of rolling stock, i.e. vehicles, vessel[s], rail
    cars, etc., is not covered under the prevailing wage laws.” (Dept.
    of Industrial Relations, Div. of Labor Statistics & Research
    Chief Dorothy Vuksich, letter to Attorney Madeline Chun,
    March 18, 1994.) The Department has also declined to apply the
    prevailing wage law to seat installation on rail cars and the
    installation of equipment on police motorcycles.
    21
    BUSKER v. WABTEC CORPORATION
    Opinion of the Court by Corrigan, J.
    The Department twice concluded that work similar to the
    onboard work here was not covered under the prevailing wage
    law. One situation concerned the installation and testing of
    equipment on Bay Area Rapid Transit cars. Another involved
    the installation of a radio system for the Southern California
    Rapid Transit District. There, work installing the radio system
    “in buildings and other structures” was determined to fall within
    the scope of the prevailing wage law while installation in
    “trains, buses, and other vehicles” was not. (Dept. of Industrial
    Relations, Industrial Relations Counsel James M. Robbins,
    mem. to Asst. Labor Commissioner Simon D. Reyes, Dec. 28,
    1987, italics added.)
    Attorney General opinions also support excluding work on
    rolling stock. In 2012, the Attorney General concluded that the
    term “public works” as used in various statutory schemes,
    including section 1720(a)(1), “comport[s] with the common usage
    and ordinary meaning of ‘public works’ as reflected in dictionary
    definitions” that define the term as “ ‘fixed works (as school,
    highways, docks) constructed for public use . . . .’ ”        (95
    Ops.Cal.Atty.Gen. 102, 108 (2012).) Over 50 years of Attorney
    General opinions contain similar reasoning.                  (See
    69 Ops.Cal.Atty.Gen. 300, 305 (1986); 25 Ops.Cal.Atty.Gen.
    153, 154 (1955).)
    The parties strenuously debate how much deference we
    should pay to the Department’s decisions, which do not have
    precedential effect. (See Kaanaana v. Barrett Business Services
    (2021) 
    11 Cal.5th 158
    , 179.) It is true that “[d]eference to
    administrative interpretations always is ‘situational’ and
    depends on ‘a complex of factors’ [citation], but where the agency
    has special expertise and its decision is carefully considered by
    senior   agency    officials,    that    decision        is   entitled   to
    22
    BUSKER v. WABTEC CORPORATION
    Opinion of the Court by Corrigan, J.
    correspondingly greater weight.” (Sharon S. v. Superior Court
    (2003) 
    31 Cal.4th 417
    , 436.)
    We need not be drawn too deeply into this thicket. Our
    task is to discern the legislative intent. In that regard, the most
    pertinent fact is that the Department’s interpretation has been
    long-standing and consistent. The same is true of the Attorney
    General opinions. Indeed, Busker cites not a single example in
    which the Department or the Attorney General has ultimately
    concluded that work on rolling stock is covered by the prevailing
    wage law.16
    Of    course, simply    because    an   administrative
    interpretation has endured for decades does not mean it is
    correct. The ultimate responsibility for the construction of a
    statute rests with the court. An agency’s interpretation is just
    one of several tools that may assist the court. (City of Long
    Beach, 
    supra,
     34 Cal.4th at p. 951.)             Nevertheless,
    “ ‘ “[c]onsistent administrative construction of statute over
    many years, particularly when it originated with those charged
    with putting the statutory machinery into effect, is entitled to
    great weight and will not be overturned unless clearly
    erroneous.” ’ ” (Sara M. v. Superior Court (2005) 
    36 Cal.4th 998
    ,
    1012.) Here, the long-standing administrative interpretations
    16
    Busker claims the Department has been inconsistent in its
    approach in this very case, citing the DLSE’s release of this
    assessment only after initially concluding prevailing wages were
    owed for the onboard work. But that initial assessment was
    quickly vacated because it was found to be inconsistent with
    long-standing policy. The sequence of events here does not
    indicate that the policy has itself been inconsistent over time. It
    reflects the Department’s adherence to its established
    interpretation.
    23
    BUSKER v. WABTEC CORPORATION
    Opinion of the Court by Corrigan, J.
    are not clearly erroneous but instead are consistent with this
    court’s construction of the relevant statutory language. They
    are significant because they tend to confirm the common
    understanding of “public works” that excludes labor on rolling
    stock. There is no indication in the record before this court that
    the administrative construction has vacillated over time or that
    there has been any call for the Legislature to step in and either
    confirm or reject this established approach.
    It might be argued that paying the prevailing wage for
    onboard work serves the general purposes of the prevailing
    wage law. (See Lusardi, 
    supra,
     1 Cal.4th at p. 985.) Of course,
    there are many specific ways to serve that general purpose. Our
    interpretation is dictated by the relevant language in the
    statutory scheme. The prevailing wage law has never been
    applied to all work financed by public funds. The Legislature
    has explicitly limited the protection to labor defined as “public
    work.” The application of the law will necessarily involve line-
    drawing exercises that distinguish between types of work that
    may be similar in many respects.
    Further, there is at least some reason to believe the
    Legislature intended to treat work performed on rolling stock
    differently from that done on fixed works. One of the primary
    purposes of the law is to protect local labor markets from
    cheaper outside labor. (See State Building & Construction
    Trades Council of California v. City of Vista (2012) 
    54 Cal.4th 547
    , 555.) Paying the prevailing wage to workers constructing
    a public building located in a particular city or county obviously
    serves that purpose. But work on rolling stock could conceivably
    be performed almost anywhere, then delivered to wherever it
    might be used. This practical reality raises a question about
    whether the law’s purpose is served by paying prevailing wages
    24
    BUSKER v. WABTEC CORPORATION
    Opinion of the Court by Corrigan, J.
    to workers that may be far away from the location of the
    governmental entity paying for the work. It also raises
    significant administrative concerns. Does the law apply to
    someone working on a high-speed rail car in a different state?
    If so, what is the relevant locality for purposes of calculating the
    prevailing wage and including those rates in the bidding and
    contracting process? (See §§ 1724, 1773, 1773.2.) At least for
    purposes of the prevailing wage law, the distinction between
    labor performed on fixed works and that done on rolling stock is
    not an arbitrary one.
    The rule favoring liberal construction is subject to an
    important proviso:    Courts “ ‘cannot interfere where the
    Legislature has demonstrated the ability to make its intent
    clear and chosen not to act [citation].’ ” (City of Long Beach,
    supra, 34 Cal.4th at p. 950.) For the reasons explained above,
    “construction” and “installation” in section 1720(a)(1) are
    generally restricted to activities associated with fixed works on
    land. Where the Legislature has expanded the meaning of
    “public works” to activities that do not directly involve
    construction work, like refuse hauling (§ 1720.3) or the delivery
    of concrete (§ 1720.9), it has done so with narrowly defined
    provisions that involve tasks intimately connected to fixed
    works on real property. The Legislature has had ample
    opportunity to expand the understanding of “public works” to
    include work on rolling stock, but it has not done so.
    C.    Onboard Work as “Integral” to Field Work
    Busker argues that even if the onboard installation does
    not independently meet the definition of “public work,” it is still
    subject to the prevailing wage law because it is integrally
    related to building the towers on the trackside, which is
    25
    BUSKER v. WABTEC CORPORATION
    Opinion of the Court by Corrigan, J.
    indisputably “public work.” The Ninth Circuit asked us to
    consider Busker’s argument. As we explain, the onboard
    installation labor is not transformed into “public work” merely
    because the railcar and locomotive components operate together
    with the towers built on land next to the tracks.
    The Ninth Circuit identified two lines of cases that may
    bear upon the question. First, it referenced a group of opinions
    that frame the inquiry as whether the work at issue “is
    integrated into the flow process of construction.” (Sheet Metal
    Workers’ Internat. Assn., Local 104 v. Duncan (2014) 
    229 Cal.App.4th 192
    , 206 (Sheet Metal); see also Williams v.
    SnSands Corp. (2007) 
    156 Cal.App.4th 742
    , 752 (Williams);
    O.G. Sansone Co. v. Department of Transportation (1976) 
    55 Cal.App.3d 434
    , 443–444 (Sansone).) These cases turn on the
    application of section 1772, which provides: “Workers employed
    by contractors or subcontractors in the execution of any contract
    of public work are deemed employed upon public work.” Under
    the approach to section 1772 taken in this case law, coverage
    under the prevailing wage law extends “to activities not
    statutorily defined as ‘public work,’ so long as that labor is
    integrated into construction or other defined public work.”
    (Mendoza v. Fonseca McElroy Grinding Co., Inc. (Aug. 16, 2021,
    S253574) __ Cal.5th __, [pp. 6–7] (Mendoza).)
    This body of law cannot aid Busker.                In Mendoza, a
    decision filed concurrently with this opinion, we reject the
    interpretation of section 1772 derived from Sansone, Williams,
    and Sheet Metal. Mendoza disapproves those cases to the extent
    they interpreted section 1772 to expand the statutory
    definitions of “public works.” (Mendoza, supra, ___ Cal.5th at
    ___ [pp. 29–30].) Section 1772 simply serves to confirm that the
    protections of the prevailing wage law extend to workers
    26
    BUSKER v. WABTEC CORPORATION
    Opinion of the Court by Corrigan, J.
    employed by contractors or subcontractors. (Mendoza, at p. ___
    [p. 16].) It was not intended to define or expand the categories
    of work that are covered by the prevailing wage law, a function
    adequately served by the provisions that define “public works.”
    Accordingly, because the onboard installation does not qualify
    as a defined “public work,” it is not subject to prevailing wage
    requirements under section 1772. 17
    Other cases mentioned by the Ninth Circuit purportedly
    stand for the principle that prevailing wage entitlement may
    arise even if the work at issue does not meet the statutory
    definition. Under this approach, work that would not otherwise
    qualify may be covered so long as other associated labor would
    constitute public work. The conclusion fails because the cases
    on which it relies do not support it. As noted earlier, section
    1720(a)(1)’s definition of public works has three facets. The
    work (1) entails construction, etc., (2) is done under contract,
    and (3) is paid for, at least in part, by public funds.
    (§ 1720(a)(1).) The Ninth Circuit points to Oxbow, supra, 
    194 Cal.App.4th 538
    , and Cinema West, LLC v. Baker (2017) 
    13 Cal.App.5th 194
     (Cinema West). As discussed below, those cases
    17
    Although the interpretation of section 1772 is addressed in
    detail in Mendoza, Justice Cuéllar has chosen to critique that
    analysis at length in a separate opinion filed in this case. (See
    generally dis. opn. of Cuéllar, J., post, at pp. 1–24.) That is so
    even though the same analysis serves as the basis for the dissent
    in Mendoza, albeit in an abbreviated fashion. (Mendoza, supra,
    ___ Cal.5th at ___ [pp. 1–5] (dis. opn. of Cuéllar, J.).) It makes
    little sense to reply here to the dissent when the analytical
    framework for the majority’s analysis is contained in a different
    case. Suffice it to say that the majority analysis in Mendoza
    rejects the critique set forth in Justice Cuéllar’s dissent in this
    case. To aid the reader, we refer generally to our analysis of
    section 1772 in Mendoza, supra, ___ Cal.5th at ___ [pp. 7–36].
    27
    BUSKER v. WABTEC CORPORATION
    Opinion of the Court by Corrigan, J.
    focus on the public funding question, not the nature of the work
    itself. Accordingly, they do not support an expanded meaning of
    “public work.”
    Oxbow concerned a petroleum coke facility. Conveyors
    used to bring coke into the plant were built under a contract
    using public funds. A separate, privately funded contract was
    used to build a roof over the conveyors. (Oxbow, supra, 194
    Cal.App.4th at pp. 542–545.) The question in Oxbow was
    whether the privately funded roof work fell within the scope of
    the prevailing wage law because it was part of a “complete
    integrated object” that included the publicly funded conveyor
    work. (Id. at pp. 548–550.) Cinema West considered a similar
    issue. There, a city entered into an agreement with a private
    developer to build a movie theater complex. As part of the
    agreement, the city used public funds to build an adjacent
    parking lot. Theater patrons could use the lot, thus facilitating
    theater development. (Cinema West, supra, 13 Cal.App.5th at
    pp. 197–202, 214.) The Cinema West court considered whether
    laborers on the privately funded theater complex were entitled
    to the prevailing wage because the theater, together with the
    publicly funded parking lot, formed a “complete integrated
    object.” (Id. at p. 215; see id. at pp. 210–215.)
    Both Oxbow and Cinema West turned on the phrase “paid
    for in whole or in part out of public funds.” (Oxbow, supra, 194
    Cal.App.4th at p. 547; Cinema West, supra, 13 Cal.App.5th at
    pp. 214–215.) All the labor at issue in both cases was
    indisputably construction work that built or installed facilities
    on real property. The only question was what construction work
    could be considered in determining the public funding question.
    Both cases extended prevailing wage protection because, in
    their view, all the construction labor, both publicly and privately
    28
    BUSKER v. WABTEC CORPORATION
    Opinion of the Court by Corrigan, J.
    financed, was done to achieve a “complete integrated object” that
    was paid for in part by public funds. Neither case is implicated
    here. (Oxbow, at p. 550; see id. at p. 552; Cinema West, at p.
    215.)   No private funding was used to build the PTC
    communications network.
    The “complete integrated object” test employed in Oxbow
    and Cinema West was derived from City of Long Beach, which
    noted that “construction” involves “ ‘[t]he act of putting parts
    together to form a complete integrated object.’ ” (City of Long
    Beach, supra, 34 Cal.4th at p. 951, quoting 3 Oxford English
    Dict., supra, at p. 794, italics added; see Oxbow, supra, 194
    Cal.App.4th at p. 549; Cinema West, supra, 13 Cal.App.5th at
    pp. 210–211.) The City of Long Beach court considered whether
    labor on an animal control facility built with private funds might
    still qualify as “public work” because the city contributed public
    funds toward preconstruction expenses, including architectural
    design, surveying, and other professional fees. (City of Long
    Beach, at p. 950.) The city’s contribution was made several
    years before the definition of “construction” was amended to
    include preconstruction activities. (Id. at pp. 946, 950.) Like
    Oxbow and Cinema West, the question in City of Long Beach
    revolved around whether labor done under a privately funded
    contract could be considered part of “construction . . . paid for in
    whole or in part out of public funds” under section 1720(a)(1).
    Because, under the statutory definition operative at the time,
    preconstruction labor was not included in the definition of
    “construction,” City of Long Beach concluded the
    preconstruction work could not be considered part of the
    privately funded facility to bring it under prevailing wage
    requirements. (City of Long Beach, at p. 946.)
    29
    BUSKER v. WABTEC CORPORATION
    Opinion of the Court by Corrigan, J.
    City of Long Beach demonstrates a fundamental
    limitation on the “complete integrated object” test. An activity
    that may be necessary or integral to complete a structure or
    other fixed work is not considered “construction” merely because
    of that relationship. In City of Long Beach, the publicly funded
    work was necessary before the privately financed facility could
    be built. But that necessity did not transform the earlier labor
    into “public work” as it was then defined by statute.
    Here, it is the field work that qualifies as “public work”
    under the statutory definition of construction in section
    1720(a)(1). That field work could be accomplished without any
    installation labor done under the Wabtec contract. Indeed, the
    distinction between the two activities is even more attenuated
    than in City of Long Beach. In that case the actual building of
    the facility could not have proceeded at all without the publicly
    financed preconstruction labor. Yet, because preconstruction
    labor was not, at the time, included in the definition of
    “construction,” the attempt to meld the two in order to fall under
    the public funding requirement failed.
    It is true that the components installed on trains partner
    with the field work, in the sense that they ultimately function
    together as part of an overall communication system. But that
    interface does not make the onboard installation integral to the
    completion of the actual construction work. If “construction”
    included any activity necessary to the operation of a public work,
    that term would bring within its expansive sweep any activity
    necessary to make the public work functional, whether or not
    the activity is related to the construction process. That
    approach has no discernable limiting principle. Here, the labor
    of those who wrote the software used in the PTC system, as well
    as those who manufactured the needed computer chips, could be
    30
    BUSKER v. WABTEC CORPORATION
    Opinion of the Court by Corrigan, J.
    considered integral to the field work because the overall system
    would not function without it. For that matter, the towers built
    on the trackside would be useless without the trains, so
    arguably the initial building of the railcars would be covered.
    Neither Oxbow nor Cinema West suggests that an activity
    is considered “construction” simply because it somehow makes
    other public work functional. In those cases, it was clear that
    both the publicly and privately funded contracts involved actual
    building or installation on land. A communication system is not
    like a manufacturing plant or theater/parking complex. The
    PTC system involves a “completed integrated object” only if
    viewed at an unduly high level of abstraction. The overall
    undertaking is much broader and more complex than building
    things on land. It is, instead, a multifaceted communications
    network. Some components of that system may indeed be
    structures or other fixed works, so that building them might
    qualify as “construction.” But work that is not otherwise defined
    as “construction” does not become so simply because it plays
    some role in making the overall communications system
    functional.
    For these reasons, the “complete integrated object” test
    does not transform the onboard installation into “public work.”
    Justice Cuéllar’s dissents in both this case and Mendoza
    risk mischaracterization of our holdings. Like our holding in
    Mendoza, the holding here is quite narrow. (See Mendoza,
    supra, ___ Cal.5th at ___ [p. 36].) We merely address the
    questions posed by the Ninth Circuit. In this case, those
    questions are whether the onboard work is included in the
    definition of public works under section 1720(a)(1), or whether
    it may be so included as “integral” to other qualifying public
    31
    BUSKER v. WABTEC CORPORATION
    Opinion of the Court by Corrigan, J.
    work. (See ante, at p. 4.) Because Justice Cuéllar’s dissent here
    has included reference to the Mendoza case as well, we
    emphasize again that nothing we say in either case should be
    read to condone any attempt to ignore the protections or
    obligations of the prevailing wage law.
    III. CONCLUSION
    We answer the Ninth Circuit’s question as follows: The
    onboard work performed under the Wabtec subcontract is not
    itself “public work” because it is not “construction” or
    “installation” involving fixed works on land. Further, merely
    because the onboard work permits the field work and the
    broader PTC communications system to function does not
    transform it into “public work.”

    BUSKER v. WABTEC CORPORATION
    S251135
    Dissenting Opinion by Justice Liu
    I agree with Justice Cuéllar that plaintiff John Busker is
    entitled to prevailing wage protection under Labor Code
    section 1772 for his work installing electronic components on
    Metrolink locomotives and rail cars. (Dis. opn. of Cuéllar, J.,
    post; all undesignated statutory references are to the Labor
    Code.) I write separately to explain that Busker’s labor is also
    entitled to prevailing wage protection under section 1720,
    subdivision (a)(1) (section 1720(a)(1)).
    Section 1771 generally provides that the prevailing wage
    “shall be paid to all workers employed on public works.”
    Section 1720(a)(1) defines “public works” to include
    “[c]onstruction, alteration, demolition, installation, or repair
    work done under contract and paid for in whole or in part out of
    public funds.” There is no dispute that Busker’s work onboard
    Metrolink trains “was done under contract and paid for with
    public money.” (Maj. opn., ante, at p. 8.) The question is
    whether his work qualifies as “construction” or “installation”
    work within the meaning of the statute.
    The text, purpose, and history of the prevailing wage law
    indicate that section 1720(a)(1) covers Busker’s onboard work.
    As today’s opinion observes, the ordinary meaning of
    “construction” and “installation” is not limited to fixed works on
    real property and can encompass work done on rolling stock.
    (Maj. opn., ante, at p. 9.) Instead of accepting the ordinary
    1
    BUSKER v. WABTEC CORPORATION
    Liu, J., dissenting
    meaning of these words, however, the court says “the general
    terms ‘construction’ and ‘installation’ are offered as categories of
    ‘public works,’ a term which itself has a generally understood
    meaning that substantially predates the prevailing wage law. It
    is that definition that gives context to the Legislature’s use of
    the terms construction and installation.” (Ibid.)
    But this has the analysis backward. The Legislature
    defined “public works” by reference to the terms “construction”
    and “installation”; it did not define “construction” and
    “installation” by reference to the term “public works.” Today’s
    opinion seems to ask what the terms “construction” and
    “installation” mean in light of what the term “public works”
    meant before enactment of the prevailing wage law. But the
    Legislature opted to define what “public works” means by
    including “construction” and “installation” as covered work.
    Citing early 1900s’ dictionary definitions of “public
    works,” the court concludes that the generally understood
    meaning of the term is limited to fixed work on land and realty.
    “It is that definition,” the court says, that informs the terms
    “construction” and “installation.” (Maj. opn., ante, at p. 9.) But
    courts typically rely on dictionary definitions when a statute
    uses language that is not otherwise defined. (See, e.g., Outfitter
    Properties, LLC v. Wildlife Conservation Bd. (2012)
    
    207 Cal.App.4th 237
    , 244.) Section 1720, subdivision (a) does
    not leave “public works” undefined; it provides an expansive and
    detailed definition of “public works” using language that, the
    court concedes, is not necessarily tied to land or realty.
    In addition, as Busker notes, the Legislature has used
    different language to define “public works” in other statutes, in
    some cases making clear that the definition is limited to fixed
    2
    BUSKER v. WABTEC CORPORATION
    Liu, J., dissenting
    structures on real property. For example, Government Code
    section 4002 defines “public work” as “the construction of any
    bridge, road, street, highway, ditch, canal, dam, tunnel,
    excavation, building or structure.” The fact that the Legislature
    defined “public work” to mean certain construction projects on
    real property in other statutes suggests it did not intend a
    similar meaning in section 1720(a)(1).
    The court says Government Code section 4002 was “not
    enacted contemporaneously with the statutory language at
    issue here.” (Maj. opn., ante, at p. 18.) But Government Code
    section 4002 “derive[s] from an uncodified statute enacted in
    1923.” (Ibid.) That statute was passed only eight years before
    the original 1931 version of the prevailing wage law. (Id. at p. 5,
    citing Stats. 1931, ch. 397, p. 910.) It is reasonable to presume
    that the Legislature was aware of the definition in Government
    Code section 4002 when it adopted a broader definition of “public
    works” in the prevailing wage law. (Voters for Responsible
    Retirement v. Board of Supervisors (1994) 
    8 Cal.4th 765
    , 779,
    fn. 3 [“the Legislature is presumed to be aware of all laws
    existent at the time it passes a statute”].)
    The 1931 version of the prevailing wage law defined
    “locality” as the “city and county, county or counties in which the
    building, highway, road, excavation, or other structure, project,
    development or improvement is situated.” (Stats. 1931, ch. 397,
    § 4, p. 912.) Today’s opinion cites this provision as evidence that
    the Legislature viewed “public works” as tied to land. (Maj. opn.,
    ante, at p. 12 & fn. 11.) But a “project” may be “situated” in a
    city or county without necessarily being tied to land. The court
    says the Legislature could not have intended “project” to have
    such a broad meaning because it “would render that term
    markedly different from the other listed items.” (Id. at p. 12,
    3
    BUSKER v. WABTEC CORPORATION
    Liu, J., dissenting
    fn. 11.) But that simply assumes the answer to the question
    presented. If the Legislature intended to restrict public works
    to real property, why did it include a term (“project”) whose
    meaning so naturally extends beyond real property? The
    Legislature could have easily omitted the term “project” in the
    1931 law but instead chose to include it. (People v. Valencia
    (2017) 
    3 Cal.5th 347
    , 357 [“ ‘[a] construction making some words
    surplusage is to be avoided’ ”].)
    It is also notable that other subparts of section 1720,
    subdivision (a) refer to real property whereas section 1720(a)(1)
    does not. (See, e.g., § 1720, subd. (a)(5) [laying of carpet in
    public buildings]; § 1720, subd. (a)(8) [tree removal work
    performed on land].)          Although subdivision (a)(5) and
    subdivision (a)(8) were not passed contemporaneously with
    section 1720(a)(1), their inclusion in the statute shows that the
    Legislature knows how to limit the definition of “public works”
    to work on land or realty when it so intends. Further, whereas
    California’s prevailing wage law does not contain an express
    “fixed work” requirement, other states’ statutes do. (See, e.g.,
    820 Ill. Comp. Stat. Ann. 130/2 [“ ‘Public works’ means all fixed
    works constructed or demolished by any public body, or paid for
    wholly or in part out of public funds”]; 
    Wyo. Stat. Ann. § 27-4-402
    (a)(vii) [“ ‘Public works’ means all fixed works
    constructed for public use, whether or not done under public
    supervision or direction, or paid for wholly or in part out of
    public funds or assessment of property owners or rights users”].)
    Even if the Legislature did intend for the words
    “construction” and “installation” to be read in light of the
    general understanding of “public works,” it is evident that
    historical usage of the term “public works” did not exclusively
    apply to fixed works attached to land. In De La Cruz v. Caddell
    4
    BUSKER v. WABTEC CORPORATION
    Liu, J., dissenting
    Dry Dock & Repair Co. (2013) 
    21 N.Y.3d 530
    , for example, the
    New York high court analyzed dictionary definitions of the
    phrase “public works” from 1891 to 2013 and found that
    “[a]lthough the illustrative examples given in dictionary entries
    are frequently fixed structures, it is clear that the notion that a
    ‘public work’ must be attached to the land is not part of [the]
    central meaning” of the term. (Id. at p. 538.) Similarly, the
    United States Supreme Court said in Title Guaranty & Trust
    Co. v. Crane Co. (1910) 
    219 U.S. 24
     that although “public works
    usually are of a permanent nature and that fact leads to a
    certain degree of association between the notion of permanence
    and the phrase,” that “association is only empirical, not one of
    logic. Whether a work is public or not does not depend upon its
    being attached to the soil . . . .” (Id. at p. 33; see also Housing by
    Vogue, Inc. v. State, Dept. of Revenue (Fla.Dist.Ct.App. 1981)
    
    403 So.2d 478
    , 480 [although all fixed works constructed for the
    state or its subdivisions qualify as public works, the term public
    works is not limited solely to fixed works]; Maurer v. Werner
    (Mo.Ct.App. 1988) 
    748 S.W.2d 839
    , 841 [rejecting the view that
    “public works” encompasses only the construction or repair of
    fixed works].)
    The applicability of the prevailing wage law to Busker’s
    onboard work is fully consistent with the statute’s purposes.
    Not only does it further the law’s “ ‘general objective’ ” of
    protecting and benefitting employees on public works; it also
    promotes many of the law’s “ ‘specific goals,’ ” including
    attracting talented workers to public works projects and thereby
    improving the efficiency and quality of such projects, and
    protecting union workers from underbidding by non-union
    workers. (Maj. opn., ante, at p. 5, citing Lusardi Construction
    Co. v. Aubry (1992) 
    1 Cal.4th 976
    , 985 (Lusardi).) By contrast,
    5
    BUSKER v. WABTEC CORPORATION
    Liu, J., dissenting
    today’s opinion authorizes contractors to provide different pay
    to workers engaged in virtually identical construction or
    installation tasks, even at the same jobsite, solely on the basis
    of whether the work occurs on a fixed structure.
    The court says “there is at least some reason to believe the
    Legislature intended to treat work performed on rolling stock
    differently from that done on fixed works. One of the primary
    purposes of the law is to protect local labor markets from
    cheaper outside labor. [Citation.] Paying the prevailing wage
    to workers constructing a public building located in a particular
    city or county obviously serves that purpose. But work on rolling
    stock could conceivably be performed almost anywhere, then
    delivered to wherever it might be used. This practical reality
    raises a question about whether the law’s purpose is served by
    paying prevailing wages to workers that may be far away from
    the location of the governmental entity paying for the work.”
    (Maj. opn., ante, at pp. 24–25.)
    It is true that “work on rolling stock could conceivably be
    performed almost anywhere, then delivered to wherever it
    might be used.” (Maj. opn., ante, at p. 24.) But today’s holding
    tips the calculus for public entities by incentivizing them to bid
    down local wages or utilize cheap out-of-market labor to perform
    such tasks. Why would a public entity choose to have such tasks
    done locally at local wage rates if they can be done at much lower
    wages overseas, out-of-state, or in other regions of California?
    By contrast, in the absence of a wage differential, public entities
    would have less or no reason to favor those workers over local
    unionized workers, consistent with the purposes of the
    prevailing wage law. (See Lusardi, 
    supra,
     1 Cal.4th at p. 987
    [“specific goals” of prevailing wage law include “protect[ing]
    employees from substandard wages that might be paid if
    6
    BUSKER v. WABTEC CORPORATION
    Liu, J., dissenting
    contractors could recruit labor from distant cheap-labor areas”
    and “permit[ting] union contractors to compete with nonunion
    contractors”].) In other words, requiring public entities to pay
    the prevailing wage for onboard work is precisely what would
    serve the “goal” of the statute: “to give local contractors and
    labor a fair opportunity to work on public building projects that
    might otherwise be awarded to contractors who hired cheaper
    out-of-market labor.” (Maj. opn., ante, at p. 5.)
    I see no discussion in the legislative history — and the
    court cites none — explaining why it would make sense to
    exclude construction or installation work performed on rolling
    stock from the scope of the prevailing wage law. No one disputes
    that if Busker’s electrical installation work had been performed
    on the wayside instead of on individual Metrolink train cars, his
    labor would have been covered under the prevailing wage law.
    By drawing a distinction between identical work performed on
    the wayside versus on rolling stock — even though the same
    underlying tools, processes, materials, skills, and expertise
    would be used to perform that work — today’s opinion attributes
    to the Legislature a limitation that is not evident in the statute’s
    text or legislative history.
    Today’s opinion notes that in 2012, the Legislature
    amended section 1720(a)(1) to clarify that “ ‘ “installation”
    includes, but is not limited to, the assembly and disassembly of
    freestanding and affixed modular office systems.’ (Stats. 2012,
    ch. 810, § 1.)” (Maj. opn., ante, at p. 15.) “The change was
    enacted to overrule a specific line of [Department of Industrial
    Relations] decisions that treated the assembly or disassembly of
    modular office systems as ‘installation’ work only if the systems
    were bolted, secured, or otherwise mounted to real property.”
    (Id. at p. 16.) The Legislature “sought to eliminate what was
    7
    BUSKER v. WABTEC CORPORATION
    Liu, J., dissenting
    viewed as an unwarranted distinction between fixed and
    freestanding modular office systems.” (Ibid.) The court says
    this legislative history does not support Busker’s argument
    because “[r]egardless of whether a modular system is fixed or
    freestanding, it remains the case that office systems are
    installed in buildings. The work takes place in a fixed structure
    on land.” (Id. at pp. 16–17.)
    But freestanding modular office systems, unlike fixed
    modular office systems, can be easily moved and transported to
    other locations; they are not permanently affixed to structures.
    In that sense, they are similar to rolling stock. And while
    freestanding modular office systems are typically found in
    buildings or on land, the same is true with respect to rolling
    stock, which is typically found in buildings like train stations or
    on fixed structures attached to land like train tracks. Further,
    the phrase “includes, but is not limited to” in the
    2012 amendment (Stats. 2012, ch. 810, § 1) suggests that the
    distinction between fixed and freestanding work has
    significance beyond modular office systems.
    Indeed, the legislative history of the amendment explains
    that the reasoning of the Department of Industrial Relations
    (Department) in some cases focused to an inordinate degree on
    whether a construction or installation project was affixed to real
    property, when the proper focus of its inquiry should have been
    on the nature of the workers’ labor. (Assem. Com. on Labor and
    Employment, Analysis of Assem. Bill No. 1598 (2011–2012 Reg.
    Sess.) as introduced Feb. 6, 2012, pp. 2–3 (Analysis of Assem.
    Bill No. 1598); see also maj. opn., ante, at p. 16 [“the
    Legislature’s focus was on the nature of the work”].)
    Specifically, the Legislature noted that failing to amend the
    prevailing wage law to rebut the Department’s reasoning would
    8
    BUSKER v. WABTEC CORPORATION
    Liu, J., dissenting
    “mean[] that the intent of [Senate Bill No. 975’s] addition of the
    term ‘installation’ [into section 1720(a)(1)] has not been
    completely effectuated” because “ ‘[t]he tools, processes and
    materials used to build and install “free standing” office
    modular systems are . . . either analogous or identical to those
    used in the construction of interior office walls’ ” and other
    aspects of installing freestanding modular office systems rely on
    the same skills and expertise as installing fixed modular office
    systems. (Analysis of Assem. Bill No. 1598, at p. 3.) Analogous
    reasoning supports Busker’s claim here.
    Finally, today’s opinion observes that the Department and
    the Attorney General have consistently excluded rolling stock
    from coverage under the prevailing wage law. (Maj. opn., ante,
    at p. 23.) But Department decisions “do not have precedential
    effect,” and “[t]he ultimate responsibility for the construction of
    a statute rests with the court.” (Id. at pp. 22–23, citing City of
    Long Beach v. Department of Industrial Relations (2004)
    
    34 Cal.4th 942
    , 951.) Here, the Department’s interpretation is
    in conflict with the statute’s text and other indicia of legislative
    intent.
    In sum, Busker’s work meets the three elements of “public
    work” set forth in section 1720(a)(1): His work was performed
    under contract. It was paid for using public funds. And his work
    onboard Metrolink trains was “construction” or “installation”
    work, and therefore “public work,” within the meaning of
    section 1720(a)(1). Busker is therefore entitled to the prevailing
    wage for his onboard labor. Although courts applying California
    law must abide by today’s contrary holding, the Legislature
    need not. It may amend section 1720, subdivision (a) to make
    clear that labor that otherwise qualifies as “public work” is not
    exempt from prevailing wage protection simply because it does

    Dissenting Opinion by Justice Cuéllar
    Over the years, tens of thousands of Californians have
    been employed on public works — from carpenters to sheet
    metal workers to electricians and a host of other “laborer[s],
    worker[s], and mechanic[s].” (Lab. Code, § 1723.)1 California’s
    prevailing wage law (§ 1720 et seq.) guarantees these workers
    pay commensurate with those in the local area for work of a
    similar character (§ 1771). This pay protects them from
    substandard wages that might be paid if contractors could hire
    cheaper out-of-market labor — a purpose that harkens back to
    the law’s Depression-era roots. (Kaanaana v. Barrett Bus.
    Servs., Inc. (2021) 
    11 Cal.5th 158
    , 165–166 (Kaanaana).) It also
    permits union contractors to compete with nonunion ones;
    benefits the public through the superior efficiency of well-paid
    employees; and compensates nonpublic employees with higher
    wages for the absence of job security and employment benefits
    enjoyed by their public counterparts. (Id. at p. 166.) As workers
    have lost influence in the workplace for a variety of economic
    and social reasons (Andrias, The New Labor Law (2016) 
    126 Yale L.J. 2
    , 5–7, 13–40), prevailing wage laws such as
    California’s law have remained a key feature of labor and
    employment.

    BUSKER v. WABTEC CORPORATION
    Cuéllar, J., dissenting
    The Legislature determined to whom these prevailing
    wage protections apply: “to all workers employed on public
    works.” (§ 1771, italics added.) Given this broad scope, and the
    prevailing wage law’s critical function, our cases emphasize that
    we must interpret the law liberally. (City of Long Beach v.
    Department of Industrial Relations (2004) 
    34 Cal.4th 942
    , 949–
    950 (City of Long Beach).) Over the past decades, the Courts of
    Appeal and the Department of Industrial Relations (DIR) have
    fulfilled this obligation in construing section 1772. That section
    provides: “Workers employed by contractors or subcontractors
    in the execution of any contract for public work are deemed to
    be employed upon public work.” (§ 1772.) The Courts of Appeal
    and the DIR have persuasively interpreted this section as
    providing prevailing wage protection for certain work beyond
    the codified definitions of “public works” (see §§ 1720–1720.9
    [defining “ ‘public works’ ”]): Work critically related to the
    “execution of” a public works contract.
    The majority breaks with this history for no good reason.
    Here and in the other prevailing wage case we also decide today,
    Mendoza v. Fonseca McElroy Grinding Co., Inc. (Aug. 16, 2021,
    S253574) __ Cal.5th __ (Mendoza),2 it radically constricts the
    prevailing wage law’s scope and undoes an established line of
    decisions — all under the rubric of judicial modesty. Casting
    aside our obligation to construe the law liberally, the majority
    holds that section 1772 does not cover functions or activities not
    expressly defined as “ ‘public works.’ ” (Maj. opn., ante, at p. 27;
    see Mendoza, at p. __ [pp. 1–2].) Instead, the majority reasons,
    2
    Mendoza contains a full discussion of section 1772, and the
    majority here simply incorporates that analysis. (Maj. opn.,
    ante, at pp. 26–27.)
    2
    BUSKER v. WABTEC CORPORATION
    Cuéllar, J., dissenting
    the section was originally intended simply to clarify that the law
    extends to workers employed by contractors and subcontractors.
    (E.g., maj. opn., ante, at p. 26; Mendoza, at p. __ [pp. 9–10, 12,
    14].)
    The majority fails to persuade.         It papers over section
    1772’s language. It overturns decades of legal decisions that had
    established a persuasive, workable framework for interpreting
    and applying the section. And it presents a strained reading of
    the prevailing wage law’s legislative history. Its interpretation
    creates odd and pernicious consequences, too: Workers fall
    outside of the law’s scope even though they perform labor critical
    to building, roadway, and other vital public infrastructure
    projects. This despite how their labor mirrors or clearly relates
    to covered work for these projects, and undoubtedly falls within
    the heartland of the prevailing wage law’s concern; and even
    though their exclusion contravenes the law’s purpose by, among
    other things, encouraging public works employers to employ
    cheaper workers for labor not defined as “public works,” but
    nonetheless constituting labor as crucial as it is integral to
    public works projects.
    With respect, I dissent.
    I.
    A.
    A careful reading of section 1772 readily serves up two
    early hints that it extends prevailing wage coverage beyond the
    codified definitions of public works. First, the section covers any
    workers “employed . . . in the execution of” a public works
    contract, sweeping broadly in its description of the workers to
    which it applies. (§ 1772.) That phrase can naturally be
    understood to cover any activity contributing to and critical to
    3
    BUSKER v. WABTEC CORPORATION
    Cuéllar, J., dissenting
    the carrying out and completion of the public works project
    being contracted for (see, e.g., Webster's 11th New Collegiate
    Dict. (2003) p. 436 [defining “execute” as “to carry out fully,”
    “put completely into effect,” or “to do what is provided or
    required”]) — even if the activity isn’t under one of the codified
    definitions.
    Second, the section uses the word “deemed” when it
    explains what happens to workers engaged in such integral
    activities. To wit: The laborers “are deemed to be employed
    upon public work.” (§ 1772, italics added.) To “deem” something
    means to treat it “as if it were really something else . . . or
    . . . has qualities that it does not have.” (Black’s Law Dict. (11th
    ed. 2019) p. 523, col. 2.) Lawmakers frequently use the word to
    establish legal fictions, including by positively “deeming”
    something to be what it is not in a statute. (Id. at pp. 523–524,
    citing Thornton, Legislative Drafting (4th ed. 1996) p. 99.) Here,
    the word fits logically with section 1772’s description of the
    workers covered; it extends prevailing wage coverage to those
    working “in the execution of” a public works contract — deeming
    their labor “public work” even if it would not ordinarily fall
    within the term’s definitions.
    The majority glosses over these two aspects of section
    1772’s language. Instead, it presses the argument that the
    language simply clarifies the category of persons entitled to
    prevailing wages by indicating that the law applies to employees
    of contractors and subcontractors performing public work under
    contract. (See, e.g., Mendoza, supra, __ Cal.5th at p. __ [pp. 8–
    9, 21].) But that reading promptly turns section 1772 into a fifth
    wheel because of section 1771, which already covers “all workers
    employed on public works” “under contract,” including those
    employed by contractors and subcontractors.        (§ 1771, italics
    4
    BUSKER v. WABTEC CORPORATION
    Cuéllar, J., dissenting
    added.) Moreover, the majority ignores the significance of
    “deemed” in the section. It effectively replaces “deemed” with
    “regarded” or “are,” and thereby contends the word simply
    describes the types of workers covered. (See Mendoza, at p. __
    [p. 22].) But even under this reading, section 1772 would still
    be surplusage. By definition, workers engaged in construction-
    type activities on a publicly funded project are employed on
    “public work,” regardless of whether they work for a contractor
    or subcontractor. In other words, there is no need to “deem[]”
    such workers to be employed on public work. (§ 1772.)
    The majority also argues that the statutory structure
    confirms its interpretation. Not so. What the majority reasons
    is this: article 1 of the law, titled “Scope and Operation,” sets
    the scope of the law by carefully defining the “public works” to
    which the law applies, whereas article 2, titled “Wages,” simply
    concerns the wages to be paid to workers covered under article
    1. (Mendoza, supra, __ Cal.5th at p. __ [pp. 9–10, 20–21].)
    Notice how much this argument depends on article titles —
    titles that don’t fundamentally change a statute’s meaning.
    (DaFonte v. Up-Right, Inc. (1992) 
    2 Cal.4th 593
    , 602.) The
    language of a statutory provision such as section 1772 cannot be
    ignored simply because it might fit more logically in a different
    part of the Labor Code. (Cf. Reliable Tree Experts v. Baker
    (2011) 
    200 Cal.App.4th 785
    , 795 [“[T]he scope of the Prevailing
    Wage Law is not to be ascertained solely from the [definitions
    in] section 1720, subdivision (a)(1). Section 1771 [of article 2] is
    also a part of the Prevailing Wage Law, and its language
    [covering maintenance work] must be taken into account” (fn.
    omitted)].)
    The majority responds that reading the statutory
    language here to expand coverage places “undue importance” on
    5
    BUSKER v. WABTEC CORPORATION
    Cuéllar, J., dissenting
    “opaque” text that offers no “limiting principle.” (Mendoza,
    supra, __ Cal.5th at p. __ [pp. 21–22].) But section 1772 speaks
    clearly. It “deem[s]” only those employed “in the execution” of a
    public works contract to be engaged in “public work.” (§ 1772.)
    This limit ensures that the section covers only work that bears
    an integral relationship with a public works project and the
    underlying covered “public work” activity being performed — as
    defined and constrained by provisions such as section 1720,
    subdivision (a).3
    Also providing a clear limit: how the prevailing wage law
    defines the type of individual it protects. “ ‘Worker’ ” as used in
    the law “includes laborer, worker, or mechanic.” (§ 1723.)
    Pertinent legislative history and DIR job classifications confirm
    that the law has generally applied only to craftspersons and
    manual laborers, many of whom perform construction-related
    tasks. (See Assem. Com. on Labor and Employment, Rep. on
    Sen. Bill No. 1999 (1999–2000 Reg. Sess.) as amended Aug. 18,
    2000, p. 4 [“Historically, workers entitled to prevailing wages
    . . . are blue collar workers”]; see also Office of the Director,
    Director’s General Prevailing Wage Determinations (June 2021)
    Dept. of Industrial Relations 4 [as of Aug. 11, 2021] [providing
    3
    Fulfilling a public works contract typically requires a host
    of tasks that don’t bear any real connection to public works. For
    example, projects may require accounting. And the Positive
    Train Control (PTC) system here required software
    development. (Maj. opn., ante, at pp. 1, 30.) No one suggests
    that these tasks, which are ancillary to covered public work, fall
    within the prevailing wage law’s ambit.

    links to a range of prevailing wage determinations for blue-
    collar workers].) In other words, the language of section 1772
    can, in context, only be understood to cover blue-collar workers
    engaged “in the execution” of a public works contract through
    construction and related trades — just like their fellow workers
    engaged in labor under one of the statutory definitions of “public
    work.”
    B.
    Over more than four decades, the Courts of Appeal and the
    DIR have consistently construed section 1772 as covering
    certain work substantially related to “the execution” of a public
    works contract, even though that work would not otherwise
    meet the statutory definition of public work. These decisions are
    no surprise given what the statute says — and they don’t bind
    us. But they deserve serious consideration and offer further
    insight into what the statute means. (Hoyt v. Board of Civil
    Service Commissioners of the City of Los Angeles (1942) 
    21 Cal.2d 399
    , 402 [the practical construction of a statute by
    decisions of the Courts of Appeal, covering many years, is
    entitled to consideration and should not be overruled unless
    clearly unsupportable]; Yamaha Corp. of America v. State Bd. of

    to agency interpretations that are embodied in quasi-legislative
    regulations, are a product of the agency’s expertise and technical
    knowledge of the issue, or constitute long-standing, consistent,
    and contemporaneous interpretations].) We address them in
    turn.
    1.
    Three appellate decisions have interpreted section 1772.
    7
    BUSKER v. WABTEC CORPORATION
    Cuéllar, J., dissenting
    The first case is O.G. Sansone Co. v. Department of
    Transportation (1976) 
    55 Cal.App.3d 434
    , 441 (Sansone). At
    issue was whether the prevailing wage law covered truck
    drivers who delivered building materials to a public works
    highway construction site — delivery work that did not
    represent defined public work. While Sansone did not explicitly
    resolve whether the drivers fell under section 1772, it effectively
    addressed that question by addressing whether the trucking
    companies that employed the drivers were subcontractors
    within the meaning of the prevailing wage law, including under
    the section. (Sansone, at p. 441; see Williams v. SnSands Corp.
    (2007) 
    156 Cal.App.4th 742
    , 752 (Williams).) The court held
    that the drivers qualified for prevailing wages because they
    worked under subcontracts to fulfill “an integral part of” the
    prime contractor’s contractual obligation. (Sansone, at p. 445.)
    As the court explained, the contract obligated the prime
    contractor to provide the project materials, including aggregate
    subbase for the roadway. (Id. at p. 443.) Rather than acquiring
    materials from a standard material supplier, the contractor
    entered into “ ‘borrow agreements’ ” with third parties. (Ibid.)
    These agreements allowed access to private sites where
    aggregate could be extracted from pits, specifically for use on the
    project. (Ibid.) The contractor engaged the trucking companies
    to deliver that material to the project. (Ibid.) The truckers did
    no construction; their delivery of necessary materials from a
    dedicated site nonetheless allowed their labor to effectively be
    “deemed” public work. The court also observed that even
    truckers making deliveries for standard material suppliers — a
    task ordinarily independent of construction activity — might be
    8
    BUSKER v. WABTEC CORPORATION
    Cuéllar, J., dissenting
    entitled to prevailing wages if the delivery was “ ‘functionally
    related to the process of construction.’ ” (Id. at p. 444.)5
    Williams, supra, 
    156 Cal.App.4th 742
     embraced Sansone.
    Williams concerned truckers who hauled excess rock and sand
    from construction sites for later use at nonpublic worksites.
    (Williams, at pp. 746–747.) It explained that the critical aspect
    of Sansone and its own determination was whether the trucking
    represented “an operation truly independent of the performance
    of the general contract for public work, as opposed to . . . work
    that was integral to the performance of that general contract.”
    (Williams, at p. 752.) Applying this test, the Williams court
    concluded that the rock and sand haulers did not perform
    covered labor under section 1772. Unlike in Sansone, no
    evidence indicated that the contract or industry custom
    obligated the lead contractor to do the hauling work. (Williams,
    at p. 753.) Nor did any evidence indicate the contractor directed
    how the trucking company would deliver the excess materials
    offsite, or how the offsite location would use the materials.
    (Ibid.) On this record, the removal of materials was “unrelated
    to the performance of the prime public works contract” and was
    “no more an integral part of the process of the public works
    project than the delivery of generic materials to the public works
    site by a [standard] material supplier.” (Ibid.)
    Finally, we consider Sheet Metal Workers’ Internat. Assn.,
    Local 104 v. Duncan (2014) 
    229 Cal.App.4th 192
     (Sheet Metal).
    5
    Although Sansone refers to the “construction” process (see,
    e.g., Sansone, supra, 55 Cal.App.3d at p. 444), its principles
    would apply to any other type of activity that qualifies as public
    work. Going forward, I occasionally use “construction” as an
    umbrella term for all the kinds of labor defined by the statute as
    public work.
    9
    BUSKER v. WABTEC CORPORATION
    Cuéllar, J., dissenting
    Here the court applied Sansone and Williams to the offsite
    fabrication context. Sheet Metal explained that the two cases
    “set forth a general framework for considering whether certain
    functions are integral to the performance of a public works
    contract.” (Sheet Metal, at pp. 205–206.) Under this framework,
    the court held that certain offsite fabrication work — fabrication
    of sheet metal components at a permanent and independent
    offsite plant — did not qualify for coverage under section 1772.
    (Sheet Metal, at pp. 196–197, 214.) The public works contract at
    issue concerned the upgrade of a community college’s facilities,
    including its heating and cooling system. (Id. at p. 196.) The
    prevailing wage law applied to the workers of the subcontracted
    sheet metal firm who installed components for the system, as
    they engaged in “construction” or “installation” under section
    1720, subdivision (a)(1). But the law did not apply to the
    workers who fabricated the components at the firm — work not
    covered by the “public work” definitions — because they
    performed labor at a facility too remotely tethered to a
    requirement or term in the public works contract and done
    independently of the offsite construction and not integrated into
    the construction process. (Sheet Metal, at pp. 211–212, 214.)6
    Three factors emerge from Sansone, Williams, and Sheet
    Metal that help determine whether labor is done in “the
    execution of [a] contract for public work” under section 1772:
    whether the labor is (1) functionally related to the construction
    process; (2) integrated into that process; and (3) done to fulfill
    6
    I do not rely on Sheet Metal to endorse or develop any
    particular viewpoint about when section 1772 would apply to
    offsite fabrication — a question we needn’t address here.
    10
    BUSKER v. WABTEC CORPORATION
    Cuéllar, J., dissenting
    the prime contractor’s obligation to complete a public works
    aspect of the project.
    Work is functionally related to the execution of the
    construction process if it requires similar labor, skills, or other
    natural relationship to covered work, and if the construction
    could not be completed as contracted for without the work in
    question. This framework provides a clear limit to prevent
    coverage for ancillary tasks, which may be required under a
    contract that includes public work but in no way impact a
    contractor’s construction obligations.
    To be “deem[ed] . . . public work” under section 1772, labor
    often must be both functionally related to the construction and
    integrated into that process. (§ 1772.) The cases provide
    specific, nonexhaustive examples of integration. Work done at
    an exclusively dedicated facility established solely to supply a
    public works project could be considered as integrated into the
    project. The facility’s existence and the work done there are
    driven entirely by the needs of the public works construction.
    (See Sheet Metal, supra, 229 Cal.App.4th at p. 212.) Sansone
    and Williams also posit other examples of integration, including
    where material is delivered and immediately incorporated as
    part of the flow of construction, or when dirt removal is required
    for pipe to be laid. (Sansone, supra, 55 Cal.App.3d at p. 444;
    Williams, supra, 156 Cal.App.4th at pp. 753–754.) What
    generally unites these differing, fact-specific examples: Each
    reflects labor that is not unduly attenuated from the actual
    construction work or other defined public work, and instead
    bears a logical connection to the preconstruction, construction,
    or postconstruction process. Unlike the federal prevailing wage
    law, California’s version does not appear to include a
    geographical limitation.       (
    40 U.S.C. § 3142
    (c)(1) [limiting
    11
    BUSKER v. WABTEC CORPORATION
    Cuéllar, J., dissenting
    coverage to persons “employed directly on the site of the work”].)
    The integration requirement for section 1772 should not be read
    to impose one.
    Finally, work falling under section 1772 generally fulfills
    the prime contractor’s obligation to complete a public works
    aspect of the project. If neither the contract nor industry
    practice nor practical circumstances impose such an obligation,
    the work done likely cannot be deemed public work. (See
    Williams, supra, 156 Cal.App.4th at p. 753.)
    These three factors have provided a rubric for applying
    section 1772 — one that’s not only longstanding, but eminently
    administrable. Applying these factors, Sansome, Williams, and
    Sheet Metal have provided clear guideposts:        They have
    illustrated how courts can construe section 1772 as expanding
    the scope of the prevailing wage law and can carefully apply it
    in a fact-intensive manner — consistent with the law’s purpose
    of protecting workers and our obligation to construe the law
    liberally — without stretching beyond reason what qualifies as
    labor “in the execution of” a public works contract. (§ 1772.) Or,
    put differently, without “ ‘interfere[ing] where the Legislature
    has demonstrated the ability to make its intent clear and chosen
    not to act [citation].’ ” (City of Long Beach, 
    supra,
     34 Cal.4th at
    p. 950.)
    The Legislature has not amended or repealed section 1772
    since the Sansone-Williams-Sheet Metal line of cases have been
    on the books.
    The majority nonetheless somehow decides these cases
    impermissibly interfere with the Legislature’s prerogative.
    (Mendoza, supra, __ Cal.5th at p. __ [pp. 21–22, 29].) It further
    contends that my embrace of these cases essentially calls on
    12
    BUSKER v. WABTEC CORPORATION
    Cuéllar, J., dissenting
    courts to arrogate legislative power. (Mendoza, at p. __ [p. 35].)
    Not at all: Giving full effect to section 1772 based on its
    language and other indicia of legislative purpose is as far from
    a judicial encroachment into the safeguards provided by the
    separation of powers (Mendoza, at p. __ [p. 35]) as Chico is from
    Chula Vista. What the appellate courts have been doing since
    they started interpreting section 1772 is precisely what we
    rightly expect courts to do when they interpret statutes. (See
    Gund v. County of Trinity (2020) 
    10 Cal.5th 503
    , 511, 514 517–
    518.) By upending decades of authority on section 1772, it would
    seem that it’s the majority that’s interfered.
    2.
    The majority’s departure from settled law becomes even
    more puzzling once we consider DIR coverage determinations.
    The DIR Director has “quasi-legislative authority to
    determine coverage of projects or types of work under
    the prevailing wage laws.”     (§ 1773.5, subd. (d).)     These
    determinations, and the statutory constructions that undergird
    them, merit deference if they represent the DIR’s long-standing,
    consistent, and contemporaneous position. (Kaanaana, supra,
    11 Cal.5th at p. 178.) Such is the case here.
    The DIR has dutifully applied the approach in Sansome,
    Williams, and Sheet Metal for effectuating section 1772. In
    numerous determinations across many years, the DIR has
    applied the factors laid out in these cases to determine whether
    particular types of labor fall under the prevailing wage law by
    virtue of their relationship to defined public work. (See, e.g.,
    Dept. of Industrial Relations, PW Case No. 2008-008 (May 28,
    2008)  [as of Aug. 11, 2021] [applying Sansone and Williams
    13
    BUSKER v. WABTEC CORPORATION
    Cuéllar, J., dissenting
    to determine that section 1772 did not cover the off-site
    manufacture of components, such as trusses and wall panels, for
    an apartment construction project, but did cover the hauling of
    such components]; Dept. of Industrial Relations, PW Case No.
    2014-023 (Nov. 6, 2014)  [as of Aug. 11, 2021] [applying
    all three cases to conclude that section 1772 covered the
    dismantling and removal of modular classrooms]; Dept. of
    Industrial Relations, PW Case Nos. 2018-028, 2018-031 (May 9,
    2020)  [as of Aug. 11, 2021] [applying all
    three cases to determine that section 1772 covered
    commissioning work to ensure that installed heating,
    ventilation, and air conditioning systems performed according
    to design and in conformity with operational needs].)
    Like the Court of Appeal cases they apply, the agency
    decisions tell us something about the scope of section 1772 and
    the practical viability of the more settled interpretation. It may
    take some judgement to discern whether a particular type of
    labor has a functional or integrated relationship with
    contracted-for public work. (See Mendoza, supra, __ Cal.5th at
    p. __ [pp. 6–7, 31–32].) But this challenge is not unique to
    section 1772.      Prevailing wage coverage determinations
    generally require examination of the “totality of the underlying
    facts” and circumstances bearing on the nature of the work at
    issue. (Oxbow Carbon & Minerals, LLC v. Department of
    Industrial Relations (2011) 
    194 Cal.App.4th 538
    , 550.) In
    engaging in this type of careful, holistic analysis under section
    1772, the DIR and courts have proven up to the task, guided by
    a longstanding framework applicable across public works
    projects.
    14
    BUSKER v. WABTEC CORPORATION
    Cuéllar, J., dissenting
    The majority upends this framework, disapproving of the
    Court of Appeal cases undergirding it and rendering existing
    administrative decisions relying on it meaningless.           (See
    Mendoza, supra, __ Cal.5th at p. __ [pp. 29–30, 33].) Yet its main
    basis for doing so — legislative history — provides no plausible
    support.
    C.
    Section 1772’s legislative history is quite thin. The section
    has remained substantively unchanged since the Legislature
    first enacted the prevailing wage law as an uncodified measure
    in 1931 (Mendoza, supra, __ Cal.5th at p. __ [p. 8]), and no
    materials from then or the law’s 1937 codification offer
    commentary on the section’s meaning (see Cal. Code Com.
    Office, Proposed Labor Code (1936), p. 88).
    The majority nonetheless urges that historical sources on
    section 1772’s original intended purpose mandate reading the
    section narrowly: as simply clarifying that the law covers
    employees of contractors and subcontractors performing defined
    public work. (Mendoza, supra, __ Cal.5th at p. __ [pp. 10–20].)
    Discerning this purpose from the section’s spare historical
    materials seems like trying to draw blood from a stone. And,
    ultimately, the majority’s read of these materials and historical
    context proves strained and doesn’t come remotely close to
    justifying its radical interpretation.
    The majority begins with the original language of section
    1772, which traces back to the 1931 uncodified prevailing wage
    law. (Stats. 1931, ch. 397, § 1, p. 910.) The relevant text
    provided that prevailing wages “shall be paid to all laborers,
    workmen and mechanics employed by or on behalf of the State of
    California, or by or on behalf of any county, city and county, city,
    15
    BUSKER v. WABTEC CORPORATION
    Cuéllar, J., dissenting
    town, district or other political subdivision of the said state,
    engaged in the construction of public works, exclusive of
    maintenance work.           Laborers, workmen and mechanics
    employed by contractors or subcontractors in the execution of any
    contract or contracts for public works with the State of
    California, or any officer or public body thereof, . . . [or any
    political subdivision] . . . , shall be deemed to be employed upon
    public works.” (Ibid., italics added.) Section 1772 derives from
    the second sentence, whereas section 1771 derives from the first
    sentence.
    According to the majority: The first sentence covered
    government workers — those “ ‘employed by’ ” the state on
    public works. (Mendoza, supra, __ Cal.5th at p. __, fn. __ [p. 11
    & fn. 11].) And the second clarified that the law also extended
    to nongovernment laborers by “ ‘deem[ing] [them] to be
    employed upon public works.’ ” (Mendoza, at p. __, fn. __ [pp.
    11–12 & fn. 12].) The majority draws a similar inference from
    the 1937 codification, which split the two sentences into the
    original versions of sections 1771 and 1772. 7 It reasons that
    section 1771 originally covered all those employed on public
    works, including government workers, and section 1772 “simply
    . . . ensure[d] that those employed by a contractor or
    subcontractor” had “the same protection . . . .” (Mendoza, at p.
    __ [p. 14].) The majority acknowledges that the 1974 legislative
    amendment to limit section 1771 to contract work potentially
    renders its reading of section 1772 surplusage, but it attempts
    7
    Section 1771 as originally enacted applied “to all workmen
    employed on public works . . . .” (Former § 1771, added by Stats.
    1937, ch. 90, p. 243.)
    16
    BUSKER v. WABTEC CORPORATION
    Cuéllar, J., dissenting
    to sidestep this by urging that the section was not originally
    surplusage. (Mendoza, at p. __ [p. 16].)
    Yet this sidestep fails.          So does the majority’s
    interpretation more broadly, because it hinges on a premise the
    majority fails to fully substantiate: that the prevailing wage law
    as originally enacted generally covered government workers.
    That proposition appears debatable at best. On the one hand,
    the majority correctly observes that the 1931 and 1937
    prevailing wage laws did not expressly exclude government
    workers (Mendoza, supra, __ Cal.5th at p. __, fn. __ [pp. 11, fn.
    11, 15]), and it marshals some support from two Attorney
    General opinions and the early prevailing wage laws of some
    states (Mendoza, at p. __ [pp. 12–13, 16–17]). And the 1931 Act’s
    use of the phrase “employed by or on behalf of” the state can
    plausibly be read to broadly cover direct government employees
    and contracted-for employees alike. (Stats. 1931, ch. 397, § 1,
    p. 910; see Mendoza, at p. __, fn. __ [p. 12, fn. 12].) On the other
    hand, that phrase can also plausibly be read merely to
    encompass the range of contract workers who engaged in labor
    on public works — irrespective of the precise nature of their
    relationship with the government, a contractor, or a
    subcontractor. (See Dept. of Industrial Relations, Div. of Labor
    Standards Enforcement, Public Works Manual (May 2018) § 2.2,
    pp. 2–3 [citing, inter alia, Sansone, supra, 55 Cal.App.3d at p.
    463].) This view finds support in the express exclusion of
    coverage for government employees in the 1897 precursor to the
    prevailing wage law (Stats. 1897, ch. 88, § 1, p. 90); the absence
    of any discussion of such coverage in our cases addressing the
    uncodified prevailing wage law (see, e.g., Metropolitan Water
    Dist. of Southern California v. Whitsett (1932) 
    215 Cal. 400
    ); and
    how many states historically limited their prevailing wage laws
    17
    BUSKER v. WABTEC CORPORATION
    Cuéllar, J., dissenting
    to contract work (Johnson, Prevailing Wage Legislation in the
    States (Aug. 1961) 84:
    8 Monthly Lab. Rev. 839
    , 842).
    More importantly, we held in Bishop v. City of San Jose
    (1969) 
    1 Cal.3d 56
     (Bishop) that the prevailing wage law as
    originally enacted did not cover government employees.
    (Bishop, at p. 64.) Though the majority offers some potentially
    tenable critiques of the decision (e.g., Mendoza, supra, __
    Cal.5th at p. __ [pp. 18–19] [it failed to address how what is now
    § 1720, subd. (a)(3) appears to cover street, sewer, and
    improvement work not performed under contract]), Bishop
    nonetheless remains equally plausible, if not more so, compared
    to the majority’s view. That view fails to take into account the
    impetus behind the prevailing wage law: It emerged to prevent
    “ ‘government contractors’ ” from “ ‘circumvent[ing] locally
    prevailing labor market conditions by importing cheap labor
    from other areas’ ” (State Building & Construction Trades
    Council of California v. City of Vista (2012) 
    54 Cal.4th 547
    , 555,
    italics added), and one of its main purposes has always been to
    “compensate nonpublic employees with higher wages for the
    absence of job security and employment benefits enjoyed by
    public employees” (Lusardi Construction Co. v. Aubry (1992) 
    1 Cal.4th 976
    , 987; see Sansone, supra, 55 Cal.App.3d at p. 459).
    Under these circumstances, we have reason to think that the
    purpose of the law did not entail covering government workers.
    But suppose the law did apply to these very workers. The
    majority fails to explain why it would have been necessary to
    include section 1772 simply to clarify that the law also protected
    those employed by contractors and subcontractors. As originally
    enacted in 1931 and codified in 1937, the prevailing wage law
    unquestionably applied to work done by contract. In fact, that
    represented the primary focus of the law. (See Bishop, supra, 1
    18
    BUSKER v. WABTEC CORPORATION
    Cuéllar, J., dissenting
    Cal.3d at p. 64; Sansone, supra, 55 Cal.App.3d at pp. 458–460.)
    Even the 1960 Attorney General opinion cited by the majority
    (Mendoza, supra, __ Cal.5th at p. __ [pp. 16–17]) acknowledged
    this reality (35 Ops.Cal.Atty.Gen. 1, 3 (1960)). If the law as a
    whole so obviously focused on contract work, there should have
    been no need to clarify that public agencies could not avoid the
    law by having the work done by contractors instead of their own
    forces. In other words, the majority not only makes section 1772
    redundant today, but also renders the Legislature’s original
    action in enacting the provision as surplusage.
    Legislatures don’t always manage to write laws that are
    perfectly clear. But it’s doubtful the Legislature used extra
    words via section 1772 to say nothing new regarding contract
    labor.
    It’s likewise doubtful the Legislature enacted the section
    merely to clarify the types of private workers covered. According
    to the majority, even if the prevailing wage law did not apply to
    government workers, section 1772 still originally served and
    continues to serve the purpose of removing any doubt that the
    law applies to the gamut of contract workers potentially
    employed on a public works project, from those contracting
    directly with the government to those formally or informally
    employed by a contractor or subcontractor. (Mendoza, supra, __
    Cal.5th at p. __ [pp. 8–9, 19–20].) But the majority provides
    nothing in the way of case law, legislative history, or historical
    context to support this alternative view. Indeed, the precursor
    language to section 1771 swept quite broadly, covering “all
    laborers, workmen and mechanics employed by or on behalf of
    the State . . . engaged in the construction of public works.”
    (Stats. 1931, ch. 397, § 1, p. 910, italics added.) So too did the
    original version of section 1771; it covered “all workmen
    19
    BUSKER v. WABTEC CORPORATION
    Cuéllar, J., dissenting
    employed on public works.” (Former § 1771, added by Stats.
    1937, ch. 90, p. 243, italics added.) In other words, the
    prevailing wage law did not appear to require any clarification
    regarding the types of private labor covered.
    Finally, even if the majority’s arguments regarding
    section 1772’s narrow purpose make this case close, that is of no
    moment. The prevailing wage statute’s liberal construction rule
    requires us to select the longstanding, broader interpretation
    offered by Sansone and its progeny. (City of Long Beach, supra,
    34 Cal.4th at pp. 949–950.) The majority doesn’t reject this rule;
    it merely pays lip service to it (Mendoza, supra, __ Cal.5th at p.
    __ [p. 4]) and ultimately flouts it in practice.
    D.
    The facts of this case underscore why reading section 1772
    liberally, to cover critical labor beyond defined “public work”
    activities, furthers the purpose of protecting and benefitting
    those employed on public works.
    Plaintiff John Busker performed a range of electrical
    installation tasks for a public works project to create a
    communication system for Metrolink public transit trains. He
    was a blue-collar worker (cf., e.g., Public Employer’s Guide to
    FLSA Employee Classification § 900), and his work would
    indisputably be covered under the prevailing wage law had it
    been performed on the wayside, rather than onboard rolling
    stock (maj. opn., ante, at pp. 25–26). In other words, he
    performed the type of work the prevailing wage law targets and
    he fits within the class of workers the Legislature designed the
    prevailing wage law to protect.
    Busker’s onboard labor readily qualifies as “construction”
    and “installation” work within the meaning of section 1720,
    20
    BUSKER v. WABTEC CORPORATION
    Cuéllar, J., dissenting
    subdivision (a)(1). (Dis. opn. of Liu, J., ante.) But even if that
    were not so, section 1772 naturally extends coverage to his
    labor. Reinforcing this conclusion is the framework from
    Sansone and subsequent cases.
    First, the completion of Busker’s onboard work served as
    a necessary component for Parsons, the prime contractor, to
    meet its obligation under the prime contract requiring creation
    of a functional Metrolink rail safety system. The prime contract
    required Parsons to “deliver[] . . . a fully integrated and fully
    functional PTC System that has been completely tested” and
    shown to reliably perform “under full-scale and full-service
    operation.” (See also Busker v. Wabtec Corporation (9th Cir.
    2018) 
    903 F.3d 881
    , 883.) Because the onboard work supplied
    equipment for the system, the work had to be completed for
    Parsons to fulfill its contractual duty.
    Second, Busker’s onboard work was integrally related to
    the covered wayside work and the PTC system as a whole. The
    onboard work occurred on-site at the project’s railyard and
    central maintenance facility. Moreover, the onboard work
    served as a key component in the completely integrated, fully
    tested system that Parsons had to deliver. The wayside work
    and the system would both have been useless without the
    onboard work. Without it, there could be no communication
    between the trains and the wayside locations, and from the
    wayside to the centralized control system. In other words,
    because the onboard work was inherently tied to the wayside
    work, it cannot be viewed as independent from that work or
    installation of the PTC system as a whole.
    Third, Busker’s onboard work related functionally to the
    covered field work. It’s not just that the field equipment and the
    21
    BUSKER v. WABTEC CORPORATION
    Cuéllar, J., dissenting
    PTC system depended on completion of the onboard work. It’s
    also that the electrical installation tasks Busker performed on
    rolling stock related to analogous installation work being
    performed just a few feet away, along the wayside. In other
    words, if there was any distinction existed between onboard and
    wayside work for purposes of section 1772, it was a not
    meaningful one: the two sets of labor appear to involve similar
    underlying tools, processes, materials, skills, and expertise —
    all going toward the same, integrated project. (Dis. opn. of Liu,
    J., ante, at p. 7.)
    Covering Busker’s labor based on this three-part
    framework for applying section 1772 achieves the specific goals
    of the prevailing wage law. For example, covering workers such
    as Busker helps attract talented craft workers to public works
    projects and thereby improves the efficiency and quality of such
    projects (Kaanaana, supra, 11 Cal.5th at p. 166) — an especially
    critical goal for a system installation aimed at preventing
    collisions and other dangerous train movements for public
    transportation. It would also protect union workers from
    underbidding by nonunion workers. (Ibid.)
    Now consider what the majority’s interpretation will
    encourage contractors to do: easily circumvent the prevailing
    wage law. Under its interpretation, contractors can simply
    employ two sets of workers: one set of workers engaged in
    defined public work and a different set of cheaper workers to
    perform any work that necessarily facilitates and supports
    defined work but does not fall under one of the “public work”
    definitions. That outcome seriously undercuts the prevailing
    wage law’s effectiveness. It essentially enables employers to
    section off portions of a public works contract in order to
    circumvent application of the prevailing wage law. As Busker
    22
    BUSKER v. WABTEC CORPORATION
    Cuéllar, J., dissenting
    points out, California Code of Regulations, title 8, section 16100,
    subdivision (b)(6) states that the “awarding body” must
    “[e]nsure that public works projects are not split or separated
    into smaller work orders or projects for the purpose of evading
    the applicable provisions of Labor Code Section 1771.”
    Classifying Busker’s onboard labor as separate or distinct from
    the wayside labor — even though both bodies of work represent
    inherently linked aspects of one unified public works project —
    would do exactly that.
    Indeed, the odd consequences of the majority’s holding in
    this case underscore the wayward nature of its interpretation.
    The idea that the prevailing wage law covers electricians and
    other skilled or manual work at a railyard and alongside a
    railway, but excludes coverage for functionally related,
    integrated, and contractually required work, simply because the
    worker happened to be working on a railcar parked at the
    railyard, strikes me as an arbitrary and implausible
    distinction — and one unsupported by any indicia of the
    prevailing wage law’s purpose.
    In spite of — and perhaps especially because of — the
    majority’s wholly unjustified constriction of section 1772, courts
    and the DIR must still strive to liberally construe the other
    provisions of the prevailing wage law, including its definitions
    of covered “public work.” Justice Liu’s dissent, which I join,
    offers one potential template for doing so. (Dis. opn. of Liu, J.,
    ante, at pp. 1–7 [illustrating how the language, legislative
    history, and purpose of section 1720, subd. (a)(1), mean it can’t
    be read as limited to fixed work on land, and to therefore create
    an arbitrary distinction between identical installation work
    performed on the wayside versus rolling stock].)
    23
    BUSKER v. WABTEC CORPORATION
    Cuéllar, J., dissenting
    II.
    Longstanding authority provided a persuasive and
    workable framework for applying section 1772 to cover certain
    labor critical to the “execution of” a public works contract and
    defined “public work.” The majority here and in Mendoza,
    supra, __ Cal.5th __ upends this established understanding of
    section 1772 without justification.
    By eviscerating the scope of section 1772, the majority
    fails to live up to our obligation to construe the prevailing wage
    law liberally. This failure strikes a heavy blow to the workers
    of our state. Across public works sites, laborers performing
    tasks vital to the performance and completion of covered “public
    work,” and public infrastructure projects as a whole, now lack
    prevailing wage law protections — even if they represent the
    very type of workers the prevailing wage law is designed to
    apply to, and even if they perform the very type of labor the law
    is meant to cover.
    With respect, I dissent. I urge the Legislature to amend
    section 1772 to restore the settled understanding of the section
    offered by Sansone and applied by the DIR: that work “in the
    execution of” a public work contract encompasses labor
    performed in preparation for, in furtherance of, or otherwise
    bearing a critical relationship to defined public work and the
    public works project as a whole, and that such labor is therefore
    subject to prevailing wage protections. (§ 1772.)
