    OPINION BY ADMINISTRATIVE JUDGE SWEET
    Appellant CDM Constructors, Inc. (CDM) 1 appeals the decision of the
    contracting officer (CO) denying its request for an equitable adjustment (REA), and the
    deemed denial of an REA. All three appeals concern the design and construction of a
    water treatment plant (WTP). 2
    ASBCA No. 60454 addresses the WTP's evaporation ponds (EPs), alleging that
    CDM is entitled to an equitable adjustment and delay damages. In particular, CDM
    alleges that the Army Corps of Engineers (Corps) constructively changed the contract
    by compelling it to include one backup EP, to use a three million gallon per day (mgd)
    average daily flow (ADF), and to use a 0.8 pan evaporation coefficient only if the
    maximum water depth was three feet or less. (App. br. at 44-53)3 The Corps argues
    1
    CDM Constructors, Inc. 's parent company was CDM Smith. CDM Smith was
    responsible for design, and CDM Constructors, Inc. was responsible for
    construction (tr. 1/38). We refer to CDM Constructors, Inc. and CDM Smith
    collectively as "CDM."
    2
    This decision only addresses entitlement.
    3
    The ASBCA No. 60454 complaint also alleges that there was a cardinal change,
    defective specifications, and breach of a covenant of good faith and fair dealing
    I
    that the contract required those design elements (gov't br. at 22-24 ). For the reasons
    discussed below, the Corps is correct about the backup EP, but not the ADF,
    evaporation coefficient, and water depth. Therefore, CDM is entitled to an equitable
    adjustment for any increased costs incurred as a result of having to use the Corps'
    ADF, evaporation coefficient, and water depth, but not as a result of having to provide
    a backup EP.
    ASBCA Nos. 60455 and 60669 address the standby generator (generator),
    alleging that CDM is entitled to an equitable adjustment under the Changes clause
    because the contract contained defective specifications. 4 In particular, CDM alleges that
    the Corps improperly rejected its design, which followed concept drawings in the
    contract. (App. br. at 53-58) The Corps responds that the contract did not require CDM
    to follow the concept drawings, which, in any event, were trumped by conflicting
    contract provisions. For the reasons discussed below, CDM is correct. Thus, CDM is
    entitled to an equitable adjustment for any increased costs incurred as a result of the
    defective specifications.
    FINDINGS OF FACT
    I. Facts Common to All Appeals
    1. On May 24, 2012, the Corps issued Request for Proposal No. W912PL-12-R-0018
    (0018 RFP), for the design and construction of a WTP at Fort Irwin, California (R4, tab 9;
    tr. 1/43, 4/126).
    2. Under the 0018 RFP, it was CDM's responsibility to "design and construct
    the [WTP] as described in the Request For Proposal (RFP) Documents contained
    herein" (R4, tab 9 at 1, 729). 5 The RFP documents:

    failing to raise them in its post-hearing brief. United Launch Services, LLC,
    ASBCA No. 56850 et al., 16-1 BCA ,r 36,483 at 177,765 (failure to address
    allegations from pleadings in post-hearing brief equated to abandonment of the
    issue).
    4
    The ASBCA Nos. 60455, 60669 complaint also alleges that there was a non-disclosure of
    superior knowledge, mutual mistake, and breach of the covenant of good faith and
    fai,r dealing (60455, 60669, compl. ,r,r 41-63). However, CDM abandoned those
    allegations by failing to raise them in its post-hearing brief. United Launch, 16-1

    [section 01 10 10], with Specific Design Requirements .. .identified in" appendix A (id. at
    1,729). Section O1 10 10 described "the requirements for appearance, function, materials,
    and types of construction in sufficient detail to enable engineering and design to be
    completed by the Contractor" (id. at 1,731). Appendix A "is intended to guide the
    completion of the design by establishing existing conditions, and desired character,
    appearance, and function of the new construction" (id. at 1,730). Thus, section 01 10 10

    6. On August 8, 2012, the Corps awarded Contract No. W912PL-12-C-0022
    (0022 contract) to CDM based upon the 0018 RFP (R4, tab 7).
    7. The 0022 contract contained the Federal Acquisition Regulation (FAR)
    52.243-4, CHANGES (JUN 2007), clause under which the Corps had to provide CDM
    with an equitable adjustment if there was any written or oral direction, instruction,
    interpretation, or determination from the CO that caused a change (R4, tab 7 at 696).
    II. Facts Unique to the EvaporatiorJ Ponds Appeal (ASBCA No. 60./54)
    A. Background
    8. A WTP produces wastewater. Because of Fort Irwin's isolated location in
    the desert, there were limited options available for the disposal of that wastewater.
    (Tr. 4/127) However, due to that desert location, it was advantageous to remove the
    liquid component of the wastewater through natural evaporation in EPs, and then to
    haul the remaining solid waste to a landfill. Therefore, the Corps decided to use EPs
    4
    to deal with the wastewater at Fort ltwin. (App. supp. R4, tab 134 at 173; tr. 1/61-62,
    86-87)
    9. The sizing of the EPs must take account of the fact that the net evaporation
    rate-i.e., the rate at which water evaporates from the EPs minus the rate at which
    water enters the EPs as precipitation-must equal or exceed the rate at which
    wastewater flows into the EPs (inflow) over time (tr. 1/92-93, 2/183, 204, 4/129-30).
    10. The measurement of the EPs' likely evaporation rate starts with a
    determination of the pan evaporation rate. The pan evaporation rate measures the rate at
    which water in a standardized test pan evaporates. That rate accounts for climatic factors
    at that particular location. However, different bodies of water will experience different
    evaporation rates at the same climatic location based upon their size, depth, salinity, and
    water temperature. To account for those characteristics, the pan evaporation rate is
    multiplied by an evaporation coefficient. (R4, tab 4 at 32-33; tr. 1/89-91)
    11. On the other side of the equation, two factors-the ADF and the recovery
    rate-determine the likely inflow. The ADF is the likely average rate per day at which
    water enters the WTP, which is determined by user demand. That ADF is multiplied
    by the remainder of the recovery rate-which is the percentage of the water entering
    the WTP that leaves the WTP as treated water-to determine the likely inflow rate.
    (R4, tab 4 at 31; tr. 1/91-92)
    12. EPs require very little maintenance (tr. 1/85). While EPs can leak, such leaks
    are rare and usually only take a few days to repair. Moreover, it is highly unlikely that
    the EPs will fail completely during the life of the WTP. (Tr. 2/184, 3/30-34) However,
    if the EPs fail or cannot be used for an extended period of time, the result would be
    catastrophic for the WTP and Fort IIWin. Because net evaporation must equal or exceed
    inflows over time, the WTP would have to be shut-down in order to avoid an overflow if
    the EPs did not adequately function over an extended period of time. That, in turn,
    would require Fort IIWin to close. To compound the problem, it would be difficult for
    the Corps to obtain funding for any major repairs. (Tr. 2/204, 4/129-30)
    B. The Contract Documents
    1. Evaporation Pond Sizing and a Standby Evaporation Pond
    13. The contract documents required CDM to design and build EPs (R4, tab 9
    at 2,107). "Actual plant configuration shall be determined by the Contractor" (id.
    at 2,113).
    14. However, the Corps provided concept design requirements. The contract
    documents stated that
    5
    Table 8 provides the Government's conceptual design unit
    requirements. The Government's concept may be
    incomplete and the Contractor shall provide a complete
    system. What is identified in Table 8 is the Government's
    expected minimum unit operations necessary. The
    Contractor shall meet the quantities in Table 8 as a
    minimum but additional units, if required to meet the
    criteria herein, shall be provided.
    (R4, tab 9 at 2, 113) Table 8 indicated "NUMBER OF PONDS ... 2 + 1 STANDBY.''
    It did not mention standby capacity. (Id. at 2, 116) 8
    15. The contract documents also indicated that "[a] total of approximately 11 acres
    is allowed for the evaporation ponds as shown in the current layout, without prior approval
    from the [contracting officer representative (COR)]. Any requirement above this area will
    require Government approval and likely revision to the Environmental Assessment (EA)
    before design approval is granted." (R4, tab 9 at 2107)9 Obtaining a revision to an EA was
    a bureaucratic hurdle that could delay the project (tr. 1/116, 4/139).
    16. The CH2M Hill drawings showed three EPs covering a total area of 10.8 acres
    (R4, tab 9 at 6,681, 6,688, 7,077-80, 9,602; app. supp. R4, tab 175).
    17. Reviewing the CH2M Hill drawings in conjunction with Table 8-which was
    derived from the CH2M Hill drawings-a reasonable contractor would have realized that
    one of the three EPs shown in the CH2M Hill drawing was not to be used in day-to-day
    operations. Table 8 showed an overall recovery rate of 99.6 or 99.7 percent. (App. supp.
    R4, tab 101 at 8-9; tr. 4/116, 141)10 At that recovery rate, at most, only two of the three
    8
    The WTP also generates a sludge of lime, which is siphoned off, and pumped to lime
    sludge lagoons. In the lagoons, the water evaporates from the sludge, and the
    Corps hauls the solids to a landfill (tr. 1/137-38). Wastewater also is pumped
    from the lime sludge lagoons to the EPs (tr. 3/92). Table 8 required 1 + 1
    standby lagoon. It also required standby units for other items, such as cartridge
    filters, electro dialysis reversal (EDR) membrane treatments, treated water pump
    stations, lime softening contact clarifiers, lime softening filtrations, reverse
    osmosis (RO) feed water storage and pump stations, RO cartridge filters, RO
    systems, and concentrate equalization basins. (R4, tab 9 at 2,114-17)
    9
    The EA is state approval to build on a certain area of land (tr. 1/115, 2/175).
    10
    To achieve that recovery rate-which was very high (tr. 1/44)-the Corps
    contemplated using several consecutive processes to extract usable water.
    Table 8 delineated the recovery rate for each process. Table 8 shows that the
    EDR provided a 92 percent recovery rate. Wastewater then went to RO stage 1,
    which provided an additional 58.8 percent recovery rate. Wastewater then went
    6
    EPs shown on the CH2M Hill drawings would be needed to ensure that inflows equaled
    net evaporation (supp. R4, tab 101 at 8-9; tr. 4/127, 170). 11
    18. The 0018 RFP initially required two assessments to evaluate the actual
    daily demand performance and the maximum daily demand performance. Reflecting
    the 99.6 or 99.7 percent recovery rate, the 0018 RFP stated that
    [T]he Contractor shall demonstrate that the design of the
    WTP material/mass balance achieves a minimum of99.6%
    recovery efficiency at 6.0 MGD at the given requirements
    for raw water quality range and treated water quality
    requirements. For the range of design flows (2.0 to 2.5
    MGD annual average daily flow; 0.8 MGD minimum daily
    flow; and 5.4 maximum daily flow), the WTP
    material/mass balance design shall be designed to exceed a
    minimum of99% recovery efficiency.
    (R4, tab 9 at 2,082; tr. 4/178)
    19. However, the problems arose in this case from the fact that the Corps
    decided to reduce the recovery rate during the solicitation phase, as reflected in
    Amendment 8 (tr. 4/159). Amendment 8 amended the above paragraph to read that:
    [T]he Contractor shall demonstrate that the design of the
    WTP material/mass balance achieves a minimum of 99-=6%
    recovery efficiency at 6.0 MGD at the given requirements
    for raw water quality range and treated water quality
    requirements. For the raage of design flows (2.0 to 2.5
    ~4GD 8:BfH:lal aYerage daily flow; 0.8 ~4GD m-inimam daily
    flo~;.r; and 5. 4 maximam daily flow), the '.VIP
    to the RO stage 2, which provided an additional 39.5 percent recovery rate.
    Wastewater then went to a mechanical evaporator, which provided an
    additional 85 percent recovery rate. Taken together, that provided a recovery
    rateofabout99.7percent. (Supp. R4, tab71 at2,114-16, tab 101 at8-9;
    tr. 4/176, 181)
    11
    Dr. Beth Gross-CDM's EP expert-opined that the CH2M Hill drawings could not
    be based upon a 99. 6 or 99. 7 percent recovery rate because, at that recovery
    rate, only one of the three EPs would be needed to balance inflows and net
    evaporation (app. supp. R4, tab 180 at 539, tab 187 at 579; tr. 3/18, 72-74).
    However, that merely shows that CH2M Hill may have conservatively designed
    the EPs with excess capacity.
    7
    materiatrmass ba:10.flee desigt1: sha:11 be desigt1:ed to exeeed a

    (R4, tab 10 at 10,353) (Strikeout in original) On the one hand, reducing the recovery
    rate benefitted contractors by reducing the risk and cost of designing such an efficient
    WTP. On the other hand, reducing the recovery rate increased the amount of
    wastewater flowing into the EPs. That meant that the contractor had to modify another
    EP parameter-such as increasing the EP surface area-in order to maintain a balance
    between inflows and net evaporation. (App. supp. R4, tab 153 at 236, tr. 1/44,
    4/178-79, 211)
    2. Average Daily Flow
    20. The contract documents did not require CDM to use any particular ADF
    (R4, tab 9).
    21. The contract documents stated that the CH2M Hill drawings were based
    upon a 3.0 mgd ADF. However, the contract documents stated that "[a]s designer's
    collect data and develop the actual system, all numerical data used to support the
    design shall be from the Contractor's inquiries and research." (R4, tab 9 at 2,107)
    22. The contract documents stated that the current ADF was 2.44 mgd, and that
    the ADF in 2010 was 2.26 mgd (R4, tab 9 at 1,727, 4,332). Dr. Beth Gross-CDM's
    EP expert-opined that it was industry standard to use historic flow data to develop
    the ADF (app. supp. R4, tab 180 at 540, tab 187 at 576; tr. 3/40, 43-44, 67-68). We
    find this uncontested testimony credible.
    23. As noted above, Amendment 8 eliminated one reference to the 2.0 to 2.5
    mgd ADF. However, it continued to provide that, in measuring actual daily demand
    performance, "the flowrates ranges include: Average flow in the range of 2.0 to 2.5
    MGD for well production rates; minimum flows at 0.8 MGD[;] and maximum
    flowrates near 5.4 MGD." (R4, tab 10 at 10,354)
    3. Evaporation Coefficient and Water Depth
    24. The contract documents did not require CDM to use any particular
    evaporation coefficient for any particular water depth (tr. 4/192).
    8
    C. Performance
    25. After award, CDM submitted several EP designs, including a 10 percent
    design, a 65 percent design, and a 100 percent design (R4, tab 4 at 109). CDM used
    the CH2M Hill drawings to create its EP design, assuming that none of the EPs were
    backup EPs (tr. 2/168).
    26. Dr. Gross opined that it was standard industry practice to construct WTPs
    without a backup EP. Dr. Gross testified that she was unaware of any other WTPs that
    have used a backup EP. (App. supp. R4, tab 180 at 537; tr. 3/25-26) However,
    Dr. Gross conceded that she "could not find any reference in the technical literature to
    a standby pond" (app. supp. R4, tab 180 at 541). Nor had she ever seen another
    contract that has used the term standby EP (tr. 3/116). We find that this term as used
    within the trade does not differ from the standard dictionary definition found in the
    New Oxford American Dictionary, 1699 (3rd ed. 2010), discussed in greater detail
    below.
    27. The 65 percent and 100 percent designs used a 3.0 mgd ADF, a five-foot
    maximum water depth, a three-foot average water depth, and a 0.8 evaporation
    coefficient (R4, tab 4 at 109).
    28. On March 6, 2013, CDM submitted a technical memorandum explaining its
    design. Regarding the evaporation coefficient and water depth, the March 6, 2013
    memorandum explained that
    In general, a conservative factor of 0. 7 is typically used to
    convert pan data to freshwater "lake" evaporation rates,
    whereas greater coefficients are used for smaller, shallower
    ponds. This coefficient generally ranges from 0. 7 to 0.95,
    depending on the size of the pond or lake (see attached
    [pages] from "Design Characteristics for Evaporation
    Ponds in Wyoming"). For purposes of sizing the
    evaporation ponds, a conservative pan evaporation
    coefficient of 0.8 was applied by CDM Smith to account
    for the smaller pond size, shallow depths (generally less
    than 3 feet) and warm water temperatures (including
    average discharge temperature to the EPs of 90 [degrees
    Fahrenheit].
    (R4, tab 47 at 14,891) The Design Characteristics for Evaporation Ponds in Wyoming
    report referenced above indicated that a reasonable coefficient for EPs in semi-arid
    conditions was 0.7 to 0.95, depending upon EP size (id. at 14,902). The March 6, 2013
    9
    memorandum proposed using a five-foot maximum water depth and a three-foot average
    water depth (id. at 14,890-93).
    29. The Corps rejected the 10 percent design, the 65 percent design, the
    100 percent design, and the March 6, 2013 technical memorandum (supp. R4, tab 105
    at 73; tr. 4/123, 133-34). In particular, the Corps rejected the evaporation coefficient.
    Moreover, the Corps rejected the designs and memorandum because they lacked a
    backup EP-meaning an EP that was operational, but not in use unless or until there was
    an emergency. 12 (R4, tab 40; supp. R4, tab 105 at 73, tr. 1/112-13, 118, 2/194)
    30. Converting one of the three EPs to a backup EP, while maintaining three
    equally-sized EPs, would have required CDM to increase the surface area to 17.2
    acres, which would have exceeded the EA (app. supp. R4, tab 175; tr. 1/113-15).
    31. After several discussions, CDM submitted a revised 100 percent design in a
    May 17, 2013 memorandum (R4, tab 37; tr. 1/117-21).
    32. The May 17, 2013 memorandum proposed three EPs-with one being
    rotated out of service every year-on 11 acres. To achieve those parameters, CDM
    reduced the ADF from 3.0 mgd to 2.25 mgd. The justification the May 17, 2013
    memorandum offered for using the 2.25 mgd ADF was that it was "mid '2.0 to 2.5
    MGD' from Appendix A." (R4, tab 36 at 14,503-07; tr. 1/121-24) Dr. Gross opined
    that it was reasonable for CDM to decrease the ADF from 3.0 mgd to 2.25 mgd
    because of the multiple measures of conservativism that the Corps added to the
    contract (app. supp. R4, tab 180 at 540, tab 187 at 576; tr. 3/40, 43-44, 67-68). The
    proposed evaporation coefficient was 0.8. While the proposed maximum water depth
    was five feet, the May 17, 2013 memorandum indicated that the water depth never
    actually would exceed three feet (R4, tab 35 at 14,503-07).
    33. The Corps responded to the May 17, 2013 memorandum in two letters
    dated May 20, 2013, and May 22, 2013. Those letters questioned the lack of a standby
    EP, the ADF, and the evaporation coefficient relative to the water depth. (R4, tabs 33,
    35) Regarding the ADF in particular, the letters explained that:

    CDM often refers to an operational, but not in use, EP as a "spare" EP (see, e.g.,
    app. br. at 3). However, as CDM correctly recognizes, the term "spare" is
    interchangeable with the term "backup" (id. at 31, 50; see also ROGET'S INT'L
    THESAURUS, 822, 1222 (4th ed. 1977) (identifying both the term backup and
    spare as being synonymous with the term substitute)). For ease of reference
    and consistency, we use the term backup EP-instead of spare EP-to describe
    the required EP that is operational, but not in use except in an emergency.

    The contract states that the current average daily flow is
    2.44 mgd and the average daily flow range of well
    production is 2.0 to 2.5 mgd. This is based on historical
    data for the Water Treatment Plant (WTP) and not listed as
    the design capacity to support future demands. WTP
    design manuals and regulatory permits .. .indicate that new
    treatment systems be sized based on future demands.
    (R4, tab 35 at 14,498-99) Regarding the evaporation coefficient and water depth in
    particular, the letters explained that "[s]ince the 0.8 coefficient is assumed based on
    shallow depths (generally less than 3 feet) being maintained [in the] ponds, and the
    design actually reaches 5 foot depth without precipitating solids, it is questionable that
    the 0.8 coefficient would still be appropriate" (R4, tab 33 at 14,494). Dr. Gross opined
    that CDM's use of a 0.8 evaporation coefficient for EPs whose water depth generally
    was less than three feet-but occasionally was up to five feet-was appropriate, and
    that the Corps' directive that an evaporation coefficient of 0.8 could be used only for
    water depths of three feet or less was not supported by technical data or scientific
    evidence (app. supp. R4, tab 180 at 539; tr. 3/38-40). We find this testimony credible.
    34. On May 22, 2013, CDM sent the Corps a notification of change. In the
    notification of change, CDM stated that:
    The essential issues center on the insistence by the
    Government that the appropriate design parameters are:
    3 MGD Average Daily Flow (ADF) and that the
    Government's definition of "standby" does not allow for
    use of the "standby" pond during routine maintenance and
    cleaning of a pond. This is inconsistent with the accepted
    engineering definition of 2 + I Standby. Also, the
    Government is not accepting our evaporation rate design
    factors that are based upon site specific data and literature
    describing standard industry practices.
    (R4, tab 34 at 14,496)
    35. The Corps responded by letter dated May 29, 2013. The May 29, 2013
    letter "constitutes formal direction" to meet three relevant design elements. First, the
    Corp directed CDM to include one backup EP. Second, the Corps directed CDM to
    use a 3 mgd ADF. Third, the Corps directed CMD to use:
    Evaporation pond factors of 0.8 for pan evaporation
    coefficient, if operated with smaller pond size and shallow
    depth of 3' or less, and actual calculated salinity correction
    11
    factor (both as stated in 17 May Evaporation Ponds Design
    Analysis memo). If design size or operation varies, please
    vary factors as necessary.
    (R4, tab 32 at 14,492)
    36. CDM responded by submitting a final design package. CDM reduced the
    surface area required for the EPs from 17.2 acres to 13.5 acres by revising its design to
    contain 8 EPs that would be in day-to-day use and one backup EP. Doing so, CDM
    was able to meet the Corps' ADF, evaporation coefficient, and water depth
    requirements. (R4, tabs 172, l 75~ tr. 1/129-30) The 13.5 acres did not require an EA
    amendment because CDM moved other equipment to keep the entire WTP within the
    EA (tr. 1/133, 4/139-40). 13
    37. The Corps accepted the final design package (tr. 1/136).
    38. The ADF has decreased over the last five years. The year prior to the
    hearing, the ADF was 1.7 mgd. (Tr. 1/142-43)
    III. Facts Unique to the Generator Appeals (ASBCA Nos. 60455 and 60669)
    A. The Southern California Edison Electrical Service Requirements
    39. In 2006, SCE published the Electrical Service Requirements (ESR). The
    ESR were "issued for the guidance and assistance of electrical contractors ... engaged in
    the installation and design of electrical service wiring and service equipment." (R4,
    tab 51 at 15,022) The ESR were guidelines with which SCE customers in Southern
    California had to comply in order to receive services. However, SCE often waived the
    ESR. (Tr. 2/64-65, 108-10, 4/32)
    40. Paragraph 12 of the ESR stated that:
    When a customer has a standby generator to supply all of
    their load during an Edison system outage, the generator
    13
    In the final design, there were only two lime sludge lagoons, both of which were in
    use. Antonia Ortiz-the Corps' technical design manager and an expert in
    WTPs-testified that the Corps initially complained about both lagoons being
    in use, but "that just kind of fell by the wayside." Because liquid waste can go
    from the lagoons to the EP, the lagoons-unlike the EPs-are not a critical
    component whose failure will cause the WTP and Fort Irwin to shut down.
    CDM provided a backup unit for the other items for which Table 8 required a
    standby unit. (Tr. 1/133, 4/152)
    12                                             J
    I
    shall be connected to the load by a double-throw switch or
    automatic relays and switches which will isolate the load
    from the Edison system before the generator is connected
    to the load. When the Edison service is re-energized, the
    generator will then be isolated from the load before the
    load is reconnected to the Edison system.
    (R4, tab 51 at 15,023)
    B. Contract Documents
    41. The contract documents required a standby generator connected to the
    normal site power by an automatic transfer switch (ATS) (R4, tab 9 at 2,161). The
    generator connection design had to satisfy two potentially relevant requirements.
    42. First, under appendix A, § 9.1.3, "[m]ultiple generators and transfer
    switches will be required when physical distances exceed 200 feet to load"
    (R4, tab 9 at 2,161).
    43. Second, section 01 10 10 provided that "[a]ll work shall be designed
    and constructed to meet all state and federal codes, standards and law" (R4, tab 9
    at 1,732). Similarly, section 01 10 10 stated that "[t]he applicable building codes
    and standards shall be used as the minimum criteria to develop the construction
    documents for areas of work not specifically defined" (id.). Regarding the
    electrical system in particular, appendix A stated that:
    All electrical equipment shall be installed in accordance
    with NFPA 70 (National Electrical Code), ANSI C2
    (National Electrical Safety Code), California's Energy
    Efficiency Standards for Residential and Nonresidential
    Buildings Title 24, Part 6, of the California Code of
    Regulations, all applicable UFC's, ETL's, TM's and other
    DOD and national standards as applicable to the system
    under consideration.
    (Id. at 2,159)
    44. The RFP initially contained the CH2M Hill drawings, but not the SCE
    drawings (tr. 1/146-47). The CH2M Hill drawings showed a primary 12 kilovolt (kv)
    network and a secondary 480 volt (v) network (tr. 1/160-61, 236, 2/22). According to the
    CH2M Hill drawings, electricity would come into the WTP from an SCE substation on
    the primary network during normal operations. After the electricity passed through an
    ATS and traveled along the primary network, transformers would step the voltage down
    13
    I
    to 480v, so that the electricity could travel on the secondary network to where it was
    needed. If the A TS sensed that the power from SCE was interrupted, it would send a
    signal to the 480v generator to start. The generator was connected to a transformer,
    which increased the voltage to 12kv. The transformer then connected to the ATS,
    through which the electricity would flow to the primary network. The A TS ensured that
    electricity only came from one source at a time, and did not back feed from the generator
    onto the SCE system. (R4, tabs 136, 145; tr. 1/147-50, 218)
    45. There was a pre-bid request for information (RFI) regarding the CH2M Hill
    drawings from another offeror besides CDM. The RFI indicated that appendix A of
    the RFP "states 'Multiple generators and transfer switches will be required when
    physical distance exceed 200 feet to load.' The initial concept drawings by CH2M
    (90-E-501) indicate one generator which connected into the SCE distribution system.
    Please confirm that Appendix A takes precedence over the CH2M design." The RFI
    did not indicate that there was an actual conflict because it did not state that the
    physical distance from the generator to the load on the CH2M Hill drawing exceeded
    200 feet. The Corps' response did not acknowledge a conflict either. Rather, the
    Corps merely responded, "[p]lease see Section 01 10 10 paragraph 2.8 Conflicts in
    RFP Criteria for precedence required." (App. supp. R4, tab 148 at 220; tr. 2/54-55)
    46. Nor may it be inferred from the Corps' response to the RFI that it read the
    RFI as establishing that there was a conflict because, the same day that the Corps
    responded to the RFI, it amended the RFP to add the SCE drawings, which were
    substantially similar to the CH2M Hill drawings. By issuing drawings showing a
    single generator using a single ATS and primary network to distribute electricity after
    the RFI quoting appendix A,§ 9.1.3, the Corps demonstrated that it did not read the
    RFI as establishing that such a design conflicted with appendix A, § 9.1.3. (App.
    supp. R4, tab 152; tr. 1/146-47, 153-55, 2/16-19)
    47. That conclusion was correct. The SCE drawings were consistent with
    appendix A,§ 9.1.3 because the distance to the load was not an issue when using the
    primary network (tr. 4/47-48). Moreover, while the SCE drawings only showed one
    generator and one ATS, the distance from the generator to the A TS-which was the
    load-was only about 100 feet (app. supp. R4, tab 152; tr. 1/153-56, 2/16-20, 89-90).
    C. Pe,formance
    48. After award, CDM submitted a 10 percent electrical design. The design
    followed the concept drawings. In particular, the design-like the drawings-showed
    one generator connected to the primary network by one ATS. (R4, tab 6 at 294; app.
    supp. R4, tab 162; tr. 1/157-58, 2/95) However, the design did not contain any
    distance measurements. In particular, it did not include any measurement of the
    distance from the generator to the load (R4, tab 6 at 294; tr. 2/32, 4/54).
    14
    49. The fact that the concept drawings and 10 percent design showed the
    generator connected to the primaiy network did not conflict with ESR 112 because the
    drawings and the design showed the generator connected to the load with an A TS that
    isolated the load from the SCE system before the generator was connected to the load
    (tr. 1/227-28, 2/30, 71-72, 144, 146). 14 Indeed, it was reasonable to interpret the ESR
    in light of the SCE drawings because the SCE drawings constituted SCE applying its
    guidelines to this particular electrical system (tr. 1/232, 2/60, 127, 130).
    50. Representatives from CDM, the Corps, and SCE attended a meeting to
    discuss the 10 percent design. As the Corps subsequently documented, the SCE
    representative indicated at the meeting that
    The emergency generator will not be able to be installed as
    originally shown. At the time of the original drawing years
    ago it was not necessaiy to submit the information through
    the generation group. Per SCE's new standards this
    installation would have to be submitted to the generation
    group and this type of installation will not be accepted.
    The Corps did not mention ESR 1 12 or appendix A, § 9.1.3. (R4, tab 6 at 295)
    51. In. response, CD M recommended using the secondaiy network to feed
    electricity from the generator to two locations, each with an ATS. Using the
    secondary network raised concerns about the distance to the load. (Tr. 4/47-48)
    Moreover, the proposed design violated appendix A,§ 9.1.3 because one of the two
    locations at which the secondaiy network would feed into the load was more than
    200 feet from the generator. Nevertheless, the Corps approved the proposed design.
    (App. supp. R4, tab 166 at 398; tr. 1/162-63, 218, 2/27-29, 4/51)
    JV Procedural History
    52. Abe Nejad-CDM's scheduling expert-prepared a time impact analysis on
    Januaiy 27, 2014, which showed that the rejection of the EP caused a 51-day delay to the
    WTP completion date (app. supp. R4, tab 178; tr. 3/144-45) However, Mr. Nejad conceded
    that, if there was a Corps-caused delay and a CDM-caused delay in the EP design, then that
    would constitute concurrent delay that would not be compensable (tr. 3/199, 4/10).
    14
    Derrick Collier-the Corps' electrical engineer for the project-testified that the
    10 percent design violated ESR 1 12 because "you can't utilize the primaiy
    distribution system and be isolated from it" (tr. 4/54). That testimony is
    inconsistent with ESR 112, which acknowledged that the load can be isolated
    from the SCE system by an ATS (R4, tab 51 at 15,023).
    15
    53. CDM subsequently submitted REAs regarding the EPs (R4, tabs 4, 29) and
    the generator (R4, tab 6).
    54. On July 22, 2015, CDM submitted a claim for changes in the EPs and the
    generator design (R4, tab 3).
    55. On May 6, 2016, the CO issued a final decision, rejecting the generator
    claim (R4, tab 2). The CO did not issue a final decision on the EPs claim, and that
    claim is deemed denied.
    56. These appeals followed.
    DECISION
    CDM has the burden of proving that there was a constructive change or a
    defective specification by a preponderance of the evidence. Amos & Andrews
    Plumbing, Inc., ASBCA No. 29142, 86-2 BCA ,r 18,960 at 95,738 (citing Teledyne
    McCormick-Selph v. United States, 
    588 F.2d 808
    (Ct. Cl. 1978)). As discussed below,
    it has satisfied that burden in part, and has not satisfied it in part.
    I. Evaporation Ponds (ASBCA No. 60-15-1)
    In particular concerning the EPs, CDM has met its burden of showing a
    constructive change regarding the ADF, evaporation coefficient, and water depth, but
    has not met its burden regarding the backup EP. In order to establish that there was a
    constructive change, a contractor must show that: ( 1) an official compelled it to
    perform work not required under the terms of the contract; (2) the official directing the
    change had contractual authority to alter the contractor's duties unilaterally; (3) the
    official enlarged the contractor's performance requirements; and (4) the added work
    was not volunteered, but resulted from the official's direction. A/fair Dev. Co.,
    ASBCA Nos. 53119, 53120, 05-2 BCA ,r 32,990 at 163,515. "Where as a result of the
    Government's misinterpretation of contract provisions a contractor is required to
    perform more or different work, or to higher standards, not called for under its terms,
    the contractor is entitled to equitable adjustments pursuant to the Changes Article,
    including extensions of time." Emerson-Sack-Warner Corp., ASBCA No. 6004, 61-2
    BCA ,r 3248 at 16,827.
    In determining what work a contract requires, "clear and unambiguous [contract
    provisions] must be given their plain and ordinary meaning, and we may not resort to
    extrinsic evidence to interpret them." Coast Fed Bank, FSB v. United States, 
    323 F.3d 1035
    , 1040 (Fed. Cir. 2003) (en bane) (citations omitted). "An ambiguity exists when
    a contract is susceptible to more than one reasonable interpretation." E.L. Hamm

    ambiguity it is not enough that the parties differ in their respective interpretations of a

    reasonableness."' NVT Techs., Inc. v. United States, 
    370 F.3d 1153
    , 1159 (Fed. Cir.
    2004). As we have held:
    Determining whether ... differing interpretations are
    reasonable begins with an examination of the plain
    language of the contract, construing the contract so as to
    effectuate its spirit and purpose giving reasonable meaning
    to all parts of the contract. In order to fall within the zone
    of reasonableness, a party's interpretation must be
    logically consistent with the contract and the parties'
    objectively ascertainable intentions.

    ,
    975 (Ct. Cl. 1965). Thus:
    We must seek to put ourselves in the position of appellant
    at the time he bid on the contract, i.e., we must seek the
    meaning that would be attached to the language by a
    reasonably intelligent bidder in the position of appellant,
    who would be expected to have the technical and trade
    knowledge of his industry and to know how to read and
    interpret technical engineering specifications and perform
    construction work in accordance with such specifications.

    negotiations and agreements." Metric Constn,ctors, Inc. v. NASA, 
    169 F.3d 747
    , 752
    (Fed. Cir. 1999). Before we can conclusively declare a contract ambiguous or
    unambiguous, we must consult the context-including trade practice and custom-in
    which the parties exchanged promises. However, a contracting party cannot invoke
    trade practice and custom to create an ambiguity where a contract was not reasonably
    susceptible to differing interpretations at the time of contracting. "Trade practice
    17
    evidence is not an avenue for a party to avoid its contractual obligations by later
    invoking a conflicting trade practice." 
    Id. As discussed
    below, the contract unambiguously required a backup pond, but
    did not require a particular ADF or evaporation coefficient for a particular water depth.
    Thus, there was no constructive change regarding the backup EP, but there was a
    constructive change regarding the ADF, evaporation coefficient, and water depth.
    A. Backup Evaporation Pond
    There was not a constructive change when the Corps compelled CDM to
    provide a backup EP that was operational, but not in use except in an emergency
    because the plain language of the contract documents required CDM to provide at least
    one backup EP. Table 8 required at least one "STANDBY'' EP (finding 14). The
    dictionary definition of the word "standby" is "readiness for duty or immediate
    deployment. ... a person or thing ready to be deployed immediately, especially if needed
    as a backup in an emergency." NEW OXFORD AM. DICTIONARY, 1699 (3rd ed. 2010).
    Thus, by using the word standby to modify the word pond, Table 8 plainly required a
    backup EP that was operationally ready for duty, but not yet deployed unless or until
    needed for an emergency.
    CDM correctly argues that context and the parties' intentions may be more
    important than dictionary definitions in determining plain meaning (app. br. at 43);
    Metric 
    ConstnJctors, 169 F.3d at 752
    . However, the context in which the parties used
    the term standby-namely the CH2M Hill drawings and Table S's recovery rates-
    confirms that they intended the term standby to have its usual meaning as a backup.
    The CH2M Hill drawings showed three EPs, covering a total area of 10.8 acres
    (finding 16). When read in the context of the 99.6 or 99.7 percent recover rate
    provided for in Table 8-which was based upon the CH2M Hill drawings-a
    reasonably intelligent contractor would understand that at least one of the CH2M Hill
    drawings' three EPs was a backup EP (finding 17).
    As context, CDM points to the fact that three EPs capable of balancing inflows
    and net evaporation would not fit within the 11 acres for which there was an EA if one
    of the EPs was a backup EP (app. br. at 28-29; app. reply br. at 8-9). That argument
    incorrectly assumes that the contract documents limited CDM to three EPs. While
    Table 8 indicated that the number ofEPs was "2 + 1 STANDBY," the contract
    documents also stated that "[w ]hat is identified in Table 8 is the Government's
    expected minimum unit operations necessary .... [A]dditional units, if required to meet
    the criteria herein, shall be provided." (Finding 14) Thus, nothing in the contract
    documents prohibited CDM from including more than three EPs in its design. And
    indeed, CDM ultimately was able to accommodate a backup EP within the EA by
    18
    using nine EPs (finding 36). As a result, the area available within the EA was
    consistent with a backup EP.
    Nor did the term standby have a customary meaning within the trade that differs
    from the dictionary definition. On the contrary, CDM's EP expert testified that she
    was unaware of any reference to the term standby EP in the technical literature or its
    use in any other contracts. Rather, she opined that it was not standard industry
    practice to construct EPs with a backup EP. (Finding 26) However, "evidence that
    some practitioners customarily accomplish tasks differently from the manner called for
    by the contract will not overcome the clear language of the contract." Metric
    
    Constructors, 169 F.3d at 752
    . 15
    CDM also argues that Table 8 merely required standby capacity in the EPs
    (app. br. at 45). That reading of Table 8 does not fall within the zone of
    reasonableness. Table 8 does not even mention capacity. Rather, the word standby
    modifies the word pond. (Finding 14) Thus, by its plain language, Table 8 required
    one standby EP; not any particular standby capacity.
    CDM also relies upon the Environmental Protection Agency's (EPA's)
    definition of the word standby as "the period of time that an impoundment is not
    accepting uranium byproduct material or tailings but has not yet entered final closure''
    (app. br. at 46; 40 C.F .R. § 61.251 (k) ). However, that definition is consistent with the
    dictionary definition of the word standby, albeit applied to modify a period of time
    instead of a physical structure (id.). The EPA definition indicates that the standby
    period-i.e., the period of time that an impound is ready for duty, but not yet deployed
    unless or until needed for an emergency-is when it is not accepting uranium
    by-product or tailings but has not yet entered final closure under EPA regulations.
    Because the word standby modifies a physical structure (i.e., an EP) instead of a
    period of time here, the plain meaning of the contract documents required CDM to
    provide a backup EP that was operationally ready for duty, but not yet deployed unless
    or until needed for an emergency. Thus, there was no constructive change when the
    Corps compelled CDM to provide a backup EP. 16
    15
    It is not our place to second-guess the soundness of the Corps' decision to require a
    backup EP. Savantage Fin. Servs., Inc. v. United States, 
    595 F.3d 1282
    , 1286
    (Fed. Cir. 2010). In any event, we note that, while the probability of an EP
    failure might be low, the impact of any such failure likely would be
    catastrophic, leading to the closure of Fort Irwin (finding 12).
    16
    CDM also points to the fact that it did not provide a backup lime sludge lagoon,
    despite the fact that Table 8 called for a standby lagoon (app. br. at 50).
    However, as the Corps explains, it objected to the lack of a backup lagoon, but
    did not insist upon strict compliance with the contract requirements in that case
    because, unlike the EPs, the lagoons were not a critical component whose
    19
    B. Average Daily Flow
    There was a constructive change when the Corps compelled CDM to utilize a
    3.0 mgd ADF. The contract documents stated that the CH2M Hill drawings were
    based upon a 3.0 mgd ADF, but it did not require CDM to use that-or any
    particular-ADF (finding 21). On the contrary, the contract documents stated that the
    CH2M Hill drawings were FIO, and it was up to the contractor to determine sizing
    (finding 3). Because the contract documents did not require the use of any particular
    ADF, the Corps constructively changed the contract documents when it compelled
    CDM to use a 3.0 mgd ADF. Indeed, because the contract documents required CDM
    to use an ADF in the range of 2.0 to 2.5 mgd to measure actual daily demand, it was
    reasonable for CDM to conclude that it could use an ADF within that range-namely a
    2.25 mgd ADF (finding 23).
    The Corps argues that CDM's constructive change claim regarding the ADF
    must fail because it was CDM-not the Corps-that changed the ADF from the
    3.0 mgd that CDM had proposed in its 65 percent and 100 percent designs to the
    2.25 mgd that CDM proposed in its revised 100 percent design (gov't br. at 26; gov't
    reply br. at 7). That is beside the point. A constructive change occurs when the
    government compels a contractor to perform work not required under the terms of the
    contract. Affair Dev., 05-2 BCA ,r 32,990 at 163,515. Thus, the relevant change was
    when the Corps required CDM to use a 3.0 mgd ADF that was not called for by the
    contract documents (findings 20, 35). It was not when CDM changed the ADF from
    an earlier design. The earlier ADFs proposed by CDM were not contract
    requirements. On the contrary, the Corps had rejected those earlier designs
    (finding 29). Absent a contract requirement or an approved design to the contrary,
    CDM was free to select an ADF, so long as it was sound and supported, which was the
    case here. 17
    failure likely would lead to the closure of Fort Irwin. Moreover, for all the
    other design elements requiring a standby unit, CDM provided a backup unit.
    (Finding 36) CDM argues that those elements are different from EPs because
    they are mechanical and thus prone to failure (app. br. at 50). However,
    nothing in the language of the contract documents evidences a mutual intent to
    draw such a distinction.
    17
    The Corps does not-and could not-argue that the 2.25 mgd ADF was unsupported
    or unsound. On the contrary, Dr. Gross testified that the 2.25 mgd ADF was
    reasonable, and the evidence shows that the ADF actually has been lower than
    2.25 mgd (findings 33, 38). Moreover, the contract documents contained
    historical data showing that the ADF was below 3.0 mgd ADF. Dr. Gross
    testified that historical data is an industry-accepted basis for determining ADF.
    (Finding 22) Further, the contract documents themselves supported a 2.25 mgd
    20
    C. Evaporation Coefficient and the Water Depth
    There also was a constructive change when the Corps compelled CDM to use a
    0.8 evaporation coefficient only if the maximum water depth was three feet or less. 18
    The contract documents did not require CDM to use any particular evaporation
    coefficient for any particular water depth (finding 24). Therefore, the Corps
    constructively changed the contract documents when it compelled CDM to use a 0.8
    evaporation coefficient only if the maximum water depth was three feet or less. 19
    As with the ADF, the Corps argues that it was CDM-not the Corps-that
    changed the evaporation coefficient relative to the water depth from that proposed by
    CDM in its March 6, 2013 memorandum (gov't br. at 32). That argument is even
    weaker than the Corps' argument regarding the ADF. First, it suffers from the same
    defect discussed above regarding the ADF. Namely, it fails to recognize that the
    relevant change for purposes of establishing a constructive change was when the Corps
    compelled CDM to perform work not required by the contract documents; not when
    CDM purportedly changed the coefficient relative to the water depth from that CDM
    proposed in the rejected March 6, 2013 memorandum.
    ADF by requiring CDM to use an ADF in the range of 2.0 to 2.5 mgd to
    measure actual daily demand (finding 23). That CDM had proposed a more
    conservative 3.0 mgd ADF earlier does not establish that the subsequent
    2.25 mgd ADF was unsound because the revised 100 percent design increased
    conservativism elsewhere (findings 27, 32).
    18
    The Corps improperly seeks to segregate CDM's evaporation coefficient claim from
    its water depth claim in an attempt to argue that CDM voluntarily used a 0.8
    evaporation coefficient (gov't reply br. at 2-3, 8). The March 6, 2013
    memorandum voluntarily proposed using a 0.8 evaporation coefficient for a
    maximum water depth of five feet (finding 28). The Corps rejected that
    proposal, directing CDM to use a 0.8 evaporation coefficient only if the
    maximum water depth was three feet or less (findings 29, 33, 35). Thus, it was
    not the evaporation coefficient alone that was compelled, but rather the
    evaporation coefficient relative to the ·water depth.
    19
    The Corps does not-and could not-argue that the use of a 0.8 evaporation
    coefficient for EPs with a maximum water depth of five feet was unsound or
    unsupported. On the contrary, Dr. Gross testified that a 0.8 evaporation
    coefficient for EPs with a maximum water depth of five feet was reasonable
    (finding 33). Moreover, CDM supported its evaporation coefficient by citing
    the Design Characteristics for Evaporation Ponds in Wyoming, which indicated
    that a reasonable evaporation coefficient was in the range of 0. 7 and 0.95
    (finding 28).
    21
    Moreover, the Corps' argument regarding the evaporation coefficient and water
    depth is even weaker than its argument regarding the ADF because it was the Corps-
    not CDM-that sought to change the evaporation coefficient relative to the water
    depth from that proposed in CDM's rejected proposal. In the March 6, 2013
    memorandum, CDM proposed using a 0.8 evaporation coefficient for EPs that had a
    maximum water depth offive feet and a usual water depth of three feet or less
    (finding 28). It was the Corps-not CDM-that changed that criteria by compelling
    CDM to use a 0.8 evaporation coefficient only for EPs that had a maximum water
    depth of three feet or less (findings 29, 33, 35). The Corps justified that requirement
    by stating that, "[s]ince the 0.8 coefficient is assumed based on shallow depths
    (generally less than 3 feet) being maintained [in the] ponds, and the design actually
    reaches 5 foot depth without precipitating solids, it is questionable that the 0.8
    coefficient would still be appropriate" (finding 33). However, in that statement, the
    Corps improperly compared apples (i.e., the March 6, 2013 memorandum's proposed
    five foot ma.ximum water depth) with oranges (i.e., the March 6, 2013 memorandum's
    proposed three feet or less general or usual water depth) to call into question the
    March 6, 2013 memorandum's evaporation coefficient by creating an illusory
    inconsistency. Because the Corps was compelling CDM to use an evaporation
    coefficient relative to the water depth that was not called for by the contract
    documents-or even by CDM' s rejected March 6, 2013 design memorandum-there
    was a constructive change.
    The Corps also argues that CDM failed to provide adequate notice (gov't br. at
    29-32). That is incorrect. While the May 22, 2013 notice of change focused upon the
    standby EP and ADF issues, it stated, "[a]lso, the Government is not accepting our
    evaporation rate design factors" (finding 34). That provided adequate notice that
    CDM considered the evaporation coefficient relative to the water depth requirement to
    be a constructive change that CDM did not voluntarily perform.
    Similarly, the Corps' argument that CDM voluntarily changed the evaporation
    coefficient relative to the water depth because the Corps merely provided feedback
    instead of direction is incorrect (gov't reply br. at 18). After the notice of change, the
    Corps issued the May 29, 2013 letter, which-by its own terms-"constitutes formal
    direction" to use a 0.8 evaporation coefficient only for water depths of three feet or
    less (finding 35) (emphasis added). Therefore, CDM did not voluntarily use a 0.8
    coefficient only for water depths of three feet or less. 20
    20
    There was no compensable delay because there was concurrent contractor-caused
    delay (i.e., failing to include a backup EP) that was intertwined with the
    government-caused delays (i.e., changes to the ADF, coefficient, and water
    depth requirements) (finding 52). Sauer, Inc. v. Danzig,

    11. The Standby Generator (ASBCA Nos. 60-1-55 and 60669)
    CDM is entitled to an equitable adjustment under the Changes clause because
    the Corps provided defective specifications regarding the generator. "When the
    government provides a contractor with defective specifications, the government is
    deemed to have breached the implied warranty that satisfactory contract performance
    will result from adherence to the specifications." Alliance Gen. Contractors, LLC,
    ASBCA No. 54979, 09-1 BCA ,r 34,030 at 168,327 (quoting Essex Electro
    Engineering, Inc. v. Danzig, 
    224 F.3d 1283
    , 1289 (Fed. Cir. 2000)). Here, by
    providing the concept drawings, the Corps warranted that satisfactory performance
    would result from adherence to those drawings (findings 44, 46). The Corps breached
    that warranty when it subsequently rejected a design that followed the concept
    drawings (finding 50).
    The Corps argues that the concept drawings were not specifications because the
    contract documents did not require CDM to comply with those drawings (gov't br.
    at 38). However, we rejected that argument in MA. Mortenson Company, ASBCA
    No. 39978, 93-3 BCA ,r 26,189 at 130,367 (holding that concept drawings create a
    warranty, even if the contract does not require a contractor to follow the drawings).
    Indeed, the conclusion that the concept drawings created a warranty is even stronger
    here than it was in Mortenson because, unlike in that case, the contract documents
    required the contractor to use the drawings to price its proposal (finding 4). 21
    The Corps also argues that it was unreasonable for CDM to follow the concept
    drawings because appendix A, § 9 .1. 3 trumped the concept drawings under the Order
    of Precedence clause (gov't br. at 36-37). Under the Order of Precedence clause,
    appendix A took priority over the concept drawings only if there was an inconsistency
    (finding 5). That clause is not applicable here because the concept drawings are
    consistent with appendix A, § 9. 1. 3. Appendix A, § 9 .1. 3 stated that "[m]ultiple
    generators and transfer switches will be required when physical distances exceed
    incurred as a result of the ADF, evaporation coefficient, and water depth
    changes from any increased costs it incurred as a result of its failure to include a
    backup EP is an issue of damages that is not addressed in this opinion.
    21
    It is true that the contract documents indicated that the concept drawings were FIO,
    and were made available to CDM for its use without any warranty of usefulness
    or suitability of purpose (finding 3). However, "[g]overnmental disclaimers of
    responsibility for the accuracy of specifications which it authors are viewed
    with disdain by the courts." Edsall Constr. Co., ASBCA No. 51787, 01-2 BCA
    ,r 31,425 at 155,181 (quoting Bromley Contracting Co., ASBCA No. 14884 et
    al., 72-1 BCA ,r 9252 at 42,902); see also Metcalf Constr. Co. v. United States,
    
    742 F.3d 984
    , 995-96 (Fed. Cir. 2014).
    23
    200 feet to load" (finding 42). The concept drawings' use of a single generator and
    ATS was consistent with appendix A, § 9.1.3 because the distance from the generator
    to the load was less than 200 feet (finding 47). Moreover, the Corps' reliance upon
    appendix A, § 9 .1. 3 is unavailing in light of the facts that the rejected 10 percent
    design did not even show distances, the Corps did not cite appendix A, § 9.1.3 as a
    basis for rejecting the 10 percent design, and the design the Corps ultimately approved
    violated appendix A, § 9.1.3 because it only had one generator that was over 200 feet
    from the load (findings 48, 50-51).
    Similarly, the Corps argues that ESR ,r 12 trumped the concept drawings under
    the Order of Precedence clause (gov't br. at 36-37). That argument is even weaker
    than its argument regarding appendix A, § 9.1.3. First, it suffers from the same defect
    discussed above regarding appendix A, § 9.1.3. Namely, the Order of Precedence
    clause does not apply because ESR ,r 12 was consistent with the concept drawings.
    The Corps is unclear precisely how it claims the concept drawings conflicted with
    ESR ,r 12 (id.). To the extent that it is claiming that the concept drawings' use of a
    single ATS or the primary network to distribute electricity was inconsistent with ESR
    ,r 12, that argument would fail because ESR ,r 12 did not require the use of multiple
    ATSs or the secondary network. ESR ,r 12 provided that
    When a customer has a standby generator to supply all of
    their load during an Edison system outage, the generator
    shall be connected to the load by a double-throw switch or
    automatic relays and switches which will isolate the load
    from the Edison system before the generator is connected
    to the load. When the Edison service is re-energized, the
    generator will then be isolated from the load before the
    load is reconnected to the Edison system.
    (Finding 40) (Emphasis added) That language expressly recognized that a single
    double-throw switch was acceptable. Nor did that language prohibit CDM from
    connecting the generator to the primary network. (Id.) Further, SCE sometimes
    waived the ESR's provisions (finding 39). Therefore, the SCE drawings can be read
    consistently with ESR ,r 12 as either the SCE applying ESR ,r 12 to this project, or
    waiving any inconsistent provisions of ESR ,r 12 (finding 49). Indeed, in its
    contemporaneous communications with CDM, the Corps did not cite ESR ,r 12 as the
    basis for rejecting the 10 percent design (finding 50).
    Moreover, even if ESR ,r 12 were inconsistent with the concept drawings, it
    would not trump the concept drawings under the Order of Precedence clause. Under
    the Order of Precedence clause, appendix A and section O1 10 10 took priority over the
    concept drawings if there was a conflict (finding 5). However, unlike with appendix
    A,§ 9.1.3, appendix A and section 01 10 10 did not require compliance with ESR
    24
    ,r 12.Appendix A and section 01 10 10 required compliance with "all state and federal
    codes, standards and law,'' "applicable building codes and standards," and "DOD and
    national standards" (finding 43). Building codes are "[l]aws, ordinances, or
    government regulations." BLACK'S LAW DICTIONARY, 195 (6TH ed. 1990). The ESR
    was not a state or a federal code, standard or law; applicable law ordinance, or
    government regulation; or a DoD standard because it was issued by a utility-not a
    government. Nor was it a national standard because it only applied to SCE's
    customers in Southern California. (Findings 3, 39) Further, the Corps does not even
    attempt to define a "building standard," or show that the ESR was a building standard
    (gov't br. at 37; gov't reply br. at 19-21). Therefore, appendix A and section 01 10 10
    did not require compliance with ESR ,r 12.
    The Corps finally argues that its response to the RFI put CDM on notice of the
    Corps' belief that there was a conflict between the CH2M Hill drawings and
    appendix A, § 9.1.3 (gov't br. at 2, 38). However, the Corps' response to that RFI did
    not indicate a belief that there was a conflict. On the contrary, a reasonable contractor
    could infer that the Corps believed that the electrical design shown in the CH2M Hill
    drawings was consistent with appendix A, § 9.1.3 from the fact that the Corps
    responded to the RFI-which purportedly established that the CH2M Hill electrical
    design was inconsistent with appendix A, § 9.1.3-by amending the RFP to add the
    SCE drawings, which showed an electrical design that was substantially similar to that
    shown in the CH2M Hill drawings. (Findings 45-46) If the Corps had believed that
    the RFI had established that such a design was inconsistent with appendix A, § 9.1.3, a
    reasonable contractor could have expected that the Corps would have responded to the
    RFI by amending the RFP to remove the inconsistent drawings and/or to add a
    consistent drawing-instead of to add drawings that continued to show a purportedly
    inconsistent design. Any subjective understanding of a conflict that was so unclearly
    communicated is insufficient to establish an actual conflict. Because the concept
    drawings were not trumped by inconsistent requirements in appendix A or
    section O1 10 10, those drawings created an implied warranty that adherence to the
    drawings would result in satisfactory contract performance, which the Corps breached.
    CONCLUSION
    On entitlement under ASBCA No. 60454, the appeal is sustained as to the
    constructive change claim relative to the average daily flow, pan evaporation
    coefficient, and water depth. Otherwise, the appeal in ASBCA No. 60454 is denied.
    On entitlement under ASBCA Nos. 60455 and 60669, the appeals are sustained on the
    25
    defective specification claim. Otherwise, the appeals in AS_BCA Nos. 60455 and
    60669 are denied. Accordingly, the appeals are returned to the parties for a
    determination of quantum consistent with this decision.
