    OPINION BY ADMINISTRATIVE JUDGE SCOTT
    PBS&J Constructors, Inc. (PBS&JC) appealed under the Contract Disputes Act
    (CDA), 
    41 U.S.C. §§ 7101-7109
    , from the contracting officer's (CO's) denial of its
    $494,962 Type I differing site conditions claim under its contract awarded by the U.S.
    Army Corps of Engineers (Corps) for the design and construction of the Whole Barracks
    Renewal Complex, Fort Hood, Texas (
    ASBCA No. 57814
    ), and from the CO's denial of
    its $368,063 claim due to the Corps' alleged unwarranted refusal to allow it to use
    shallow foundations in certain areas (balcony piers claim) (
    ASBCA No. 57964
    ). The
    Board consolidated the appeals and held a four-day hearing in Fort Worth, Texas. We
    decide entitlement only. For the reasons stated below, we deny the appeals.
    DIFFERING SITE CONDITIONS CLAIM-
    ASBCA No. 57814
    FINDINGS OF FACT
    1. On 5 August 2008 the Corps issued a request for proposals (RFP) for the
    subject firm-fixed-price contract for a design/build barracks project (R4, tab 3) 1 The RFP
    included the Corps' August 2007 geotechnical report (GTR). PBS&JC submitted a
    proposal on 24 October 2008 (R4, tabs l 5A, l 5B; see also R4, tab 3 at 1 of 39; tr. 1134 ).
    1
    Unless otherwise noted, "R4" refers to the Rule 4 file and the Corps' supplemental
    Rule 4 file in 
    ASBCA No. 57814
    . Some of those documents, e.g., the contract,
    also apply to 
    ASBCA No. 57964
    .
    The Corps awarded it the contract on 27 February 2009, in the amount of $32,373,000. It
    incorporated the RFP and GTR. (R4, tab 3 at 2, 18 of39, § 1.2., at 209 of796)
    2. PBS&JC was a sister company to Peter Brown Construction (Brown). Atkins
    North America, Inc. (Atkins), the parent company, had design responsibility. PBS&JC
    began doing business as Brown at project start. 2 Kleinfelder Central (Kleinfelder) was
    Brown's geotechnical engineer and Alliance Geotechnical Group of Austin, Inc.,
    (Alliance) was its geotechnical inspector. Alliance prepared daily activity observation
    reports and pier inspection reports. (R4, tabs 7B, 7C at Bates 259-394; tr. 1/36-38, 2/135)
    3. The RFP incorporated the Federal Acquisition Regulation (FAR) 52.236-2,
    DIFFERING SITE CONDITIONS (APR 1984) clause by reference, which provides concerning
    Type I differing site conditions that the contractor is promptly to notify the CO of
    "subsurface or latent physical conditions at the site which differ materially from those
    indicated" in the contract. If the conditions do differ materially and increase the
    contractor's cost or time in performing any part of the contract work, an equitable
    adjustment is to be made. The RFP also incorporated by reference the FAR 52.243-4,
    CHANGES (JUN 2007) clause. (R4, tab 3 at 6 of 39)
    4. For potential time extensions, the RFP included anticipated adverse weather
    delays, including four days each in January through June, September and October, and
    December, and three days each in July, August and November (R4, tab 3 at 2-3 of 11 ).
    5. The RFP required at§ 01 10 00, Statement of Work (SOW), that the contractor
    have a licensed geotechnical engineer interpret the GTR and develop earthwork and
    foundation recommendations and design parameters and that:
    If any additional subsurface investigation or laboratory
    analysis is required to better characterize the site or develop
    the final design, the Contractor shall perform it under the
    direction of a licensed geotechnical engineer .... lf differences
    between the Contractor's additional subsurface investigation
    and the government provided soils report or the reasonably
    expected conditions require material revisions in the design,
    an equitable adjustment may be made, in accordance with the
    provisions of the Differing Site Conditions clause.
    (R4, tab 3 at 31 of 796, ~ 5 .2.2.1.) The engineer was to prepare a final geotechnical
    evaluation report, to be part of the contractor's first foundation design submittal (R4,
    tab 3 at 31of796, ~ 5.2.2.2., at 108 of796, § 01 33 16, Design After Award,~ 3.5.3.).

    Like the parties, we usually refer to appellant PBS&JC for convenience.

    6. The GTR included boring logs, noting that the 19 test holes were drilled in
    December 2003 and January 2004, for another project at the site that did not materialize.
    The logs identified the nature of the subgrade material through which the test bore was
    drilled; the test bore's depth; whether the subgra<;le material caved in or blocked the test
    bore; and whether water was present. Ten of the borings were drilled to depths from 21
    to 49 feet; nine were drilled from 3 to 10112 feet, referred to by the Corps, although not in
    the GTR, as the "deep" and "shallow" borings, respectively. The shallow borings had the
    prefix "lOA," Fort Worth's traditional designation for pavement borings. (R4, tab 3 at
    209 of796, tab 4 at Bates 2-3, 28-31; tr. 3/231, 241-42) The 19 borings were drilled
    across a site of over 12.4 acres, of which the barracks footprint was about 1.5 acres
    (tr. 1/49-50; Corps 12/19/12 resp. to app's proposed fact findings (APFF) in 
    ASBCA No. 57814
     (Corps dsc resp.) at 7, ~ 18). The project called for more than 540 drilled
    piers, each with an anticipated depth of32 feet (R4, tab 4 at Bates 12; tr. 2/99, 3/231).
    7. The GTR stated:
    Groundwater conditions were monitored during drilling
    operations, immediately upon completion of the test holes,
    and after 18-hour and 24-hour observation periods. Static
    water levels were measured in six of the nineteen
    borings ... with depths ranging from 11.8 feet to 28.5 feet
    below existing grade. The remaining test holes were dry or
    blocked.
    (R4, tab 4 at Bates 3) Static water levels in the six borings were reported as follows:
    Boring                              Static Level, feet
    3ST-5440                                   21.5
    8A4C-5445                                  28.5
    8A-5446                                    11.8
    3ST-5447                                   15.2
    8A4C-5450                                  18.0
    8A-5454                                    13.2
    (Id.) The list did not include boring 8A4C-5443, which the log described as "DRY" but
    which showed water present (finding 9).
    3
    8. The GTR continued:
    Subsurface conditions representative of the project site
    are shown on the boring logs .... actual subsurface conditions in
    areas not sampled may differ from those predicted. The
    nature and extent of variations across the sites may not
    become evident until construction commences, and the actual
    construction process may alter subsurface conditions as well.
    If variations become evident at the time of construction, [the
    Corps] should be contacted to determine if the
    recommendations presented in this report need to be
    reevaluated.
    (R4, tab 4 at Bates 6)
    These discussions are provided to the Design-Build
    Contractor to develop his foundation and pavement
    designs .... It should be noted that the discussions presented
    herein are based on the results of the Government
    geotechnical field investigation and laboratory testing
    program, engineering studies, and previous engineering
    experience with similar structures at Fort Hood. The
    Design-Build Contractor should consider the information
    provided in this report and comply with the requirements and
    recommendations presented herein when developing his
    foundation and pavement designs. The Design-Build
    Contractor may use the subsurface boring log and lab testing
    data presented herein as the sole basis to formulate his
    foundation and pavement designs, or, at his option, the
    Design-Build Contractor may supplement the information
    provided herein by his own geotechnical field investigations
    and laboratory testing program.
    (Id. at Bates 9)
    Groundwater should be anticipated during pier
    construction. Therefore, the drilling contractor shall be
    required to have temporary steel casing and pumps at the job
    site prior to construction of the drilled piers.
    (Id. at Bates 13)

    9. Regarding the six borings within the building's footprint (see R4, tab 2 at 9),
    the boring logs,§ 15, "ELEVATION GROUND WATER," stated:
    8A4C-5443                   DRY
    8A-5446                     AT 11.8' IMMEDIATELY
    8A4C-5445                   24 HR. CHECK - 28.5'
    3ST-5447                    AT 15.2'
    8A-5448                     DRY BLOCKED at 18'
    8A4C-5450                   SEE BELOW [showing "WATER
    LEVEL" at 24 hour check at 18.0'
    and open to 33']
    (R4, tab 4 at Bates 29-30, Sheets B201, B202) For boring 5443, which came within the
    building's footprint when PBS&JC added exterior walkways and balconies to its design
    (tr. 1157, 60; finding 54), despite the "DRY" note in§ 15, the log described the "WATER
    LEVEL" at the 24 hour check as at 13.5' and the hole as "BLOCKED" at 21.0' (R4, tab 4
    at Bates 29, Sheet B201). Although boring 5448 showed no static water level, and
    indicated "DRY" in§ 15, it also described the soil as "slightly moist" and "very moist"
    (id. at Bates 30, Sheet B202). For boring 5450, the log indicated that there was no
    sloughing above 30' (R4, tab 4 at Bates 30, Sheet B202; Corps dsc resp. at 21-22, ii 44).
    10. PBS&JC admits groundwater was detected from 11.8' to 28.5' but contends
    that the water at 11.8' was not an intrusion but "perched" water (app. 1/28/13 dsc. resp. to
    Corps 12/19/12 dsc br. (app. dsc resp.) at 9, ii 24). Wayne A. Eddins, Alliance's project
    manager (tr. 2/29-30), who was not an expert witness, described perched water as:
    [U]sually ... when you've got a zone of clay and water migrates
    down and just sits right there. It [doesn't] go any further and
    it doesn't come anywhere else. It just kind of got to that layer
    and stopped until it evaporates or migrates horizontally .
    ... [P]retty much a perched water table is something
    that's seasonal, based on rainfalls.
    (Tr. 2/120-21) He described "static water" as water that "reached a certain level within
    the boring and it stopped" (tr. 2/54). He opined that perched water in a boring does not
    indicate that casing will be required (tr. 2/121). Mr. Eddins confirmed that the GTR and
    borings did not discuss the quantity of water or provide any information concerning the
    type of water flow a contractor could expect to encounter (tr. 2/83).
    5
    11. PBS&JC understood that, under the Corps' technical regulations, no more
    than three inches of water could accumulate in a pier hole prior to the placement of
    concrete (tr. 2/50-51, 3/235; see R4, tab 7B at Bates 166-222 ("Less than three inches of
    water was present at the time of concrete placement."); see also tr. 2/20-21 ). Temporary
    casing keeps the drilled pier hole dry and maintains the integrity of its sidewalls, allowing
    concrete placement (see R4, tab 7C at Bates 224-27; app. dsc resp. at 17, ii 40).
    12. Joseph A. Williams became PBS&JC's senior project manager in February 2010
    (tr. 1133-34), about a year after contract award. On 24 February 2010 the Corps'
    Administrative Contracting Officer (ACO) and Resident Engineer, Harvey B. Hammer,
    rejected PBS&JC's geotechnical report as unsatisfactory (R4, tab 23; tr. 3/265-66).
    13. PBS&JC submitted to the Corps a design analysis dated 2 June 2010 by
    Bryan Rose, a licensed geotechnical engineer and Kleinfelder's principal project
    representative. PBS&JC ultimately did not proffer Mr. Rose as an expert witness. The
    parties agree that PBS&JC used the analysis, based upon the Corps' data, to estimate
    soils' potential vertical movement and consolidation, foundations' bearing capacities, and
    construction considerations, including deep foundations. (
    ASBCA No. 57964
     (57964)
    R4, tab 9 at 35, 58, 60-61; tr. 1/37, 2/253-54, 256, 3/48-49; Corps dsc resp. at 48, ii 131)
    Regarding the GTR, the analysis stated at§ 2.4, Subsurface Water:
    [G]roundwater levels were monitored during drilling,
    immediately upon completion of each boring, and after
    18-hour and 24-hour observation periods. Static water levels
    were observed in 6 of 19 borings at depths of 11.8 to 28.5 feet
    below existing grade. The remaining borings were noted to
    be dry or blocked at the time of measurement.
    These short-term field observations generally do not permit an
    accurate evaluation of subsurface water levels at this location
    and should not be interpreted as a groundwater study. It
    should be noted that the observations made within the [GTR]
    may not represent conditions at the time of construction and
    the presence of groundwater may affect certain construction
    activities and long-term performance of the foundations. The
    quantity of transient water is variable and is dependent on
    climatic conditions before and during construction. The
    foundation contractor should check the subsurface water
    conditions just prior to foundation e?'cavation activities.
    6
    (57964 R4, tab 9 at 66) It stated at§ 4.4 Drilled Pier Foundation Construction Criteria:
    7.   Zones of sloughing soils or groundwater may be
    encountered within the soil, which could cause
    sloughing of pier sidewalls to occur. Thus, we
    recommend that provisions be incorporated into the
    plans and specifications to utilize temporary steel casing
    to control sloughing and/or groundwater during pier
    construction should it occur.
    (57964 R4, tab 9 at 82)
    14. According to Mr. Rose, bore hole collapse or blockage causes include
    water, drilling, excavation, and loose soils. Water and blockage indicate a potential,
    but not definite, casing need. What governs casing is the relative stability of the
    borehole sidewalls, and the volume of water and rate at which it is encountered.
    Water in the GTR's borings did not communicate that casings had to be used because
    the logs did not provide enough information to ascertain its volume or flow rate.
    Mr. Rose was not suggesting that the logs were deficient. He opined that they were
    largely consistent with the applicable geotechnical standard of care. (Tr. 2/266-67,
    3/12, 19-20, 78, 97)
    15. Per Mr. Rose, borings within a building's footprint are considered first and are
    the most relevant regarding materials to be encountered, but proximity is less important
    where water is concerned. Adjacent borings and any in the project's vicinity are relevant
    because water moves regionally through the project site. (Tr. 3/6, 29-31, 80-82, 90) All
    water shown in a boring log is relevant:
    All water is relevant, whether it be a static groundwater level
    table, a perched condition with sufficient quantity, even
    though it's not static--it's a transient or temporary condition--
    could, when drilling through it, infiltrate into the pier hole and
    adversely affect construction and requir[ e] casing.
    (Tr. 3/83) However, he opined that, while borings might alert a contractor to the
    possibility of encountering water during construction, they do not provide enough
    information to ascertain how much will be encountered (tr. 3/7, 79).
    16. Mr. Rose, who was experienced with the subsurface conditions at Fort Hood
    and its vicinity, found the conditions disclosed in the GTR to be generally consistent with
    the two or three previous reports he had done at Fort Hood and with the geological profile
    7
    one would expect in that region. Kleinfelder did not see anything indicating that it might
    need to do a supplemental investigation. (Tr. 2/260, 262-63)
    17. According to Ronald Harris, the Corps' supervisor of materials quality
    assurance testing at Fort Hood, if a drill hole is blocked, it indicates that the sidewall has
    been compromised and, in 99% of the cases, water is involved, usually the reason for the
    blockage. He found that every project boring hole from 20-40' showed water, blockage,
    or both. In a 1July2010 preparatory meeting with PBS&JC and subcontractors on drilled
    piers he advised that they needed casing on site for each anticipated diameter size hole so
    they would be ready. (Tr. 3/205, 211-14, 216-17, 233)
    18. The parties agree that PBS&JC began drilling and pouring concrete piers on
    about 11August2010. Its project superintendent, Ron Hartshorn, arrived on site in late
    August 2010. (R4, tabs 7B, 7C at Bates 226, 395; tr. 1/37, 3/115, 118; app. dsc resp. at
    17, il 42; app. 1/28/13 balcony piers reply (app. hp reply) at 17, il 89).
    19. On 7-8 September 2010 a severe storm occurred. PBS&JC's Quality Control
    Reports (QCRs) referred to "extreme weather conditions" (R4, tab 12 at 605, 607), and
    recorded a total of 8.25" of rain on the project site (id. at 604-05). Mr. Williams
    described it as a "tropic storm" like "a one-in-50-year event" (tr. 1/78). He believed that,
    in connection with compaction problems he attributed to a prior contractor, the heavy
    rainfall in a short period created unsuitable material that directly related to the amount of
    water encountered during drilling. He thought that the effect on the subgrade material
    could have resulted in a French drain that impacted 305 drill holes that had immediate
    water and were cased and another 239 that were cased although no water was visible at
    first (see finding 20). Only four holes did not contain water. (R4, tab 12 at Bates 604-05;
    app. 2nd consol. supp. R4, tab A-021 at 1; ti'. 1/63-64, 68, 70-74, 78-79, 175; Corps dsc
    resp. at 7, il 17)
    20. Most often when drilling began water would start coming in the pier sidewalls
    at differing rates and elevations. In the 305 holes where water was present, casing was
    required because it was coming in "so fast" according to Alliance's Mr. Eddins (tr. 2/49).
    In the 239 holes where no water was present initially, after one to five hours, there were
    saturated soils and sidewalls and water at the bottom of the pier that could not be pumped
    down to an acceptable level. Terry Herzog, of Herzog Foundation Drilling (Herzog), a
    subcontractor to PBS&JC's subcontractor Gibson Concrete (Gibson), was the project's
    drilling superintendent. Herzog pumped out the holes the first day or so but thereafter did
    not try pumping because "the water was coming in too fast and caving off the sides"
    according to Mr. Herzog (tr. 2/9). Herb Morgan, the Corps' quality assurance inspector,
    recommended that even the holes that initially did not contain water be cased. PBS&JC,
    Gibson, Alliance and Herzog all concurred. PBS&JC ultimately had to case most of the
    pier holes because of significant groundwater intrusion, unstable subgrade materials, or
    8
    both. (Tr. 1143-44, 66-67, 2/5-10, 24-26, 44-45, 49-51; app. dsc resp. at 18, ~ 44; see also
    R4, tab 7C at Bates 395-96)
    21. PBS&JC's QCRs mentioned groundwater at times (R4, tab 12 at Bates 543,
    546,548,553,556,558,560,563,566,569,572, 574,577,580,583,587,589, 592,595,
    598). Gibson's daily reports, under "PROBLEMS/UNUSUAL CONDITIONS," mention
    water or casing on 12, 13, 17 and 18 August 2010 but do not mention groundwater
    concerning pier drilling thereafter, through 16 November 2010 (R4, tab 7A at Bates 62,
    63, 65-130). Alliance's daily reports for 13 August 2010 through 16 November 2010
    regularly state that "groundwater infiltration was observed" in the piers being drilled
    (e.g., R4, tab 7B at Bates 162, 222). They do not mention the amount, the infiltration
    rate, or the elevation at which water was encountered. None of these documents
    characterize the groundwater as immediate, massive or continuous.
    22. By letter of 11 January 2011 to the Corps' project engineer, Andy Heinchon,
    PBS&JC submitted a $494,962 request for equitable adjustment (REA) alleging a Type
    I differing site condition regarding the drilled piers. It did not request more time. By
    letter of 28 January 2011 to ACO Hammer, it converted its REA into a CDA claim,
    which it certified on 4 February 2011. (R4, tab 7C at Bates 224, 227-28, tabs 8, 10;
    tr. 4/86)
    23. According to PBS&JC's claim, the GTR and RFP "clearly state that a deep
    foundation system will be required" and the GTR, "while limited," provided 19 borings to
    depths of up to 49' (R4, tab 7C at Bates 224). The GTR indicated that ground water was
    in 6 of the 19 borings, from 11.8' to 28.5', and "it was reasonable to infer that
    groundwater was present to some extent" (id.). Nine of the borings were "within the
    consideration limits for the proposed building location" and they were evaluated (id. at
    Bates 225). Those were 1OA-5442, 8A4C-5443, 1OA-5444, 8A4C-5445, 8A-5446,
    3ST-5447, 8A-5448, lOA-5449, and 8A4C-5450 (tr. 11118). PBS&JC alleged that, while
    there was groundwater in four of the nine borings, this did not indicate that measures
    beyond pumping would be required. Further study to determine the type of material at the
    groundwater's depth was needed. Conditions affecting drilling included "quality of
    material..., cave-in considerations, dynamic versus static pressure of groundwater.. .,
    season of borings, and condition of groundwater (perched or aquifer)" (R4, tab 7C at
    Bates 225). The borings were in December 2003 and January 2004, which PBS&JC
    alleged to be two of the wettest months and considered the groundwater conditions
    encountered then to be a ''worst case scenario" (id.).
    24. The claim alleged that, based upon the RFP, "it was concluded that casing
    would be required at a ratio of 2 holes per 9 drilled, or 22.2% of the drilled pier
    locations" (R4, tab 7C at Bates 225). It alleged that, while PBS&JC had made a 22%
    pier casing estimate, starting on 16 August 2010, casings in all piers were required due
    9
    to groundwater levels and apparent instability of the shaft walls at depth. While the
    2 June 2010 Kleinfelder report had discussed potential groundwater and made
    recommendations should temporary casing be required, "no extraordinary geological
    conditions were noted or implied ... that would have changed [PBS&JC's] assumptions at
    bid time" (id. at Bates 226). It developed that PBS&JC had to case 97% of the drill
    holes (tr. 1145).
    25. The claim included what PBS&JC described as its "notes relative to the
    evaluated borings" upon which it relies in support of its alleged pre-proposal 22% casing
    estimate (R4, tab 7C at Bates 225). The handwritten notes are undated, unsigned and
    anonymous (id. at Bates 256-57). Mr. Williams, who authored and signed the REA,
    speculated that they were from its preconstruction department, which put its proposal
    together, but he was not involved in the casing estimate, could not recall any
    communications with its creator(s), and did not know who had arrived at the estimate or
    when (tr. 1/46, 117, 119-22, 201-02). He acknowledged:
    Again, that would be a question probably better, I guess,
    asked of our preconstruction department. I mean, when I
    came on the project, per my previous testimony, was in
    February 2010, and the project was already awarded.
    (Tr. 11124)
    26. The contractors on the project did not give Alliance or Mr. Eddins a project
    casing estimate and, prior to the hearing, he never saw the handwritten notations on the
    boring logs that PBS&JC contend were made by its preconstruction department in
    reaching a casing estimate (tr. 2/62-63, 95, 124).
    27. Mr. Rose of Kleinfelder was never asked to provide any casing estimate and
    was not involved in any 22% casing estimate by the contractor (tr. 3/75, 79).
    28. Although the annotations on the boring logs reflect a 22% casing estimate,
    they also note that "our driller assumed" that 30% of the drill holes would have to be
    cased, without identifying the driller or when the alleged assumption was made
    (R4, tab 7C at Bates 257). There is no evidence t~at any driller had been selected prior
    to PBS&JC's proposal. According to the project's drilling superintendent, Terry Herzog,
    it is normal and customary for the driller and the concrete subcontractor to bring casings
    and pumps to a project in case of groundwater. He was not involved with any pier
    casing estimate for the project. His father took care ofHerzog's bid estimates.
    Terry Herzog was unaware of any 30% casing estimate. He never saw the boring logs.
    He did not know PBS&JC's senior project manager Williams. (Tr. 2/16-18, 22, 24-25)
    10
    29. Without explanation, PBS&JC did not call anyone to testify who was involved
    in reaching the alleged 22% estimate. There is no contemporaneous evidence that the
    notes were prepared pre-proposal or of PBS&JC's pre-proposal assumptions concerning
    site conditions. Thus, we find that PBS&JC has not substantiated its claim that it
    reasonably interpreted and relied upon the GTR and boring logs, and arrived at a 22.2%
    casing estimate, prior to its submission of its proposal to the Corps.
    30. The claim alleged that an attached Alliance letter supported PBS&JC's
    "pre-proposal assumptions" (R4, tab 7C at Bates 226). The claim appears to have
    included two Alliance letters on geotechnical and differing site conditions issues
    (findings 31, 32), but, ultimately, PBS&JC did not proffer anyone from Alliance as an
    expert witness (tr. 2/31-32). As with Kleinfelder's various reports, we have considered
    Alliance's letters but do not deem them to be expert opinions.
    31. A 21 December 2010 letter to Mr. Williams from Mr. Eddins, prepared by
    Alliance's project engineer, pertained to geotechnical conditions during the drilled pier
    installation, based upon Alliance's review of the RFP, GTR and boring logs and
    interviews with its inspectors. Alliance stated, inter alia, that only 2 of the GTR's
    19 borings were within the structure's footprint, of which only 1 documented
    groundwater and that, based upon the GTR, about 31 % of the borings indicated water.
    However, in most cases, temporary casing was necessary to stem the water flow and/or
    prevent further sidewall sloughing and to limit water accumulation to 3" or less. The
    stabilization effort began on about 23 August 2010. Mr. Eddins acknowledged at the
    hearing that two borings within the building's footprint contained water, not one.
    (R4, tab 7C at Bates 395-96; tr. 2/43, 52-53, 103-04)
    32. The claim also included a 7 January 2011 letter to PBS&JC from Mr. Eddins,
    stating that there had been a differing site condition, based upon Alliance's review of the
    RFP, the GTR, the boring logs and the 2 June 2010 Kleinfelder report, and that:
    In our professional opinion, it is reasonable to assume that the
    anticipated subsurface conditions re~ating to groundwater
    issues and casing requirements were substantially different
    than those encountered during the installation of drilled piers
    for the project.
    The conditions described in the above referenced documents
    would lead to a reasonable expectation of encountering
    groundwater in less than [30%] of the drilled piers and even
    fewer indications of potential side-wall instability. Based
    upon the conditions encountered during the drilled pier
    operations, and as presented in the documentation generated
    11
    during the full-time observation and reporting of the
    operations, casing was required in over [90%] of the piers due
    to either excessive groundwater intrµsion, side-wall instability
    and/or a combination of both conditions.
    (R4, tab 7C at Bates 258)
    33. PBS&JC alleged at the hearing and in briefing, but did not articulate in its
    claim, that a prior contractor's failures to compact soils after demolition and to remove
    debris were differing site conditions (see app. 1115/12 initial post-hearing br. at 10-12,
    APFF 65-76; finding 19). However, Mr. Eddins acknowledged that he could not say that
    debris and soils that were not as dense as others affected drilling or caused or contributed
    to the water encountered. He confirmed that the soils at the lower depths were competent
    enough to pour a pier and were as represented in the GTR and that the subgrade materials
    were what the boring logs indicated. In his view, the water caused the soil to become
    incompetent. (Tr. 2/48-49, 85, 94)
    34. Alliance had several Fort Hood projects involving pier installation. In a
    November 2010 geotechnical report for one of them, contractors were told to anticipate
    groundwater and to assume that about 100% of piers must be cased. In Mr. Eddins' view,
    if there is no direction about the number of piers to be cased, a contractor must arrive at a
    number but "you never know until you drill the hole" (tr. 2/58-59, 112). The record is
    unclear but he apparently believed that a 22%-38% casing estimate would have been
    reasonable for the subject project, based upon the GTR. (App. 2nd consol. supp. R4,
    tab A-018 at 19; tr. 2/57, 64-65, 74-76, 80, 82; app. dsc resp. at 30, if 79)
    3 5. Herzog had prior experience at Fort Hood. For example, it had drilled piers in
    2007 or 2008 on another barracks project a few blocks away, on the same street as the
    subject project. Water was present, but it came in slowly and could be pumped. There
    was little caving. There was a requirement to have casings and pumps on that job, but no
    casings were used. (Tr. 2/11-12) Hitting groundwater on a drilling project and the use of
    casings was not unusual in Terry Herzog's experience. He had extensive experience with
    jobs that required casing and, at the time of the hearing, Herzog had "just started a job
    that has to be all cased" (tr. 2/24). However, the amount of groundwater on the subject
    project was unusual for him compared to his other jobs (tr. 2/14, 23-24).
    36. According to Mr. Williams, a basis of PBS&JC's differing site conditions
    claim is that it encountered a "massive amount" of water during installation of deep pier
    foundations (tr. 1135) and, for 305 of the drilled piers (see finding 19), there was a "steady
    and consistent" or "constant and immediate" flow, such that, as soon as holes were
    drilled, it was "clearly evident" that casings were required (tr. 1156, 64-65, see also
    tr. 1190, 160-61, 163, 169-70). However, he did not find the conditions encountered to be
    12
    different than shown in the boring logs. Rather, the logs did not quantify the amount of
    water to be encountered, its flow rate into the holes, how many casings or pumps would
    be required, how often the contractor would have to case or pump, or the number of holes
    that could be pumped versus the number that had to be cased (tr. 1/76-77, 208-09). Under
    cross-examination Mr. Williams testified:
    Q     Okay. And you testified, did you not, that this
    was somehow different, a different condition from that which
    was shown on the boring logs. Is that accurate?
    A       Well, I think what I said was the conditions that
    we faced and the amount of water that we encountered,
    there's no way to determine from the boring logs the quantity
    and magnitude of the water. There was water shown in the
    logs, yes, but there's no way to quantify how much water.
    Q       Okay. So the logs don't show the reader or
    indicate to the reader how quickly that water inflow occurred.
    Right? I mean, isn't that what you just- I thought that's what
    you just said, that the logs don't indicate the rate of inflow of
    groundwater. Is that accurate?
    A      Yes.
    (Tr. 11170)
    37. The CO denied PBS&JC's differing she conditions claim by final decision
    dated 25 July 2011 and this timely appeal ensued (R4, tabs 1, 2).
    3 8. The contract completion date was 31 October 2011. It was not completed on
    time. Final inspection was on about 8 December 2011. The Corps did not assess
    liquidated damages. (Tr. 4/143-44)
    Corps' Expert Evidence on Differing Site Conditions Claim
    39. Kenneth McCleskey, a registered professional geologist, with a Bachelor of
    Science degree in geology and a Master of Science degree in civil engineering, prepared
    the GTR in substantial part. As of the hearing, he was acting chief of the Corps'
    geotechnical engineering and design section at Fort Worth and had been acting chief of
    the geotechnical branch. He was offered and admitted without objection as an expert in
    the area of geotechnical engineering. He submitted an expert report dated 18 July 2012.
    (R4, tab 33; tr. 3/222-24, 228) We consider him to be a mixed fact and expert witness.
    13
    40. In his expert report Mr. McCleskey stated that, per PBS&JC's REA, in
    arriving at its claimed 22% pier casing estimate, it had considered groundwater and
    stability conditions in nine borings it deemed to be in the area of the new facility's
    construction. He noted that three of them were "lOA" borings that had only been drilled
    to a depth of 1O' in areas of proposed new pavement construction for the prior project and
    were not intended to be used for foundation design. Piers were to be founded at depths of
    32'. Moreover, all other groundwater levels and instability noted in the borings were at
    depths exceeding 10'. Static groundwater levels between 11.8' and 28.5' below grade
    were measured in five of the six remaining borings. The sixth boring, 8A-5448, was
    blocked at 18', indicating unsuitable material, but in the comments on the boring log
    included in its claim, PBS&JC mistakenly stated that there was no cave-in. (R4, tab 4 at
    Bates 30, Sheet B202, tab 33 at 1-2; see also McCleskey expert testimony at tr. 3/231,
    241-42 (lOA borings drilled too short to be reasonably considered for foundation design)
    41. In Mr. McCleskey's expert opinion, PBS&JC's analysis of the boring logs in
    its claim was not reasonable. It did not consider all of the deep borings, including those
    that were not in the building's footprint, but were close. All of the deep borings were
    consistent in terms of materials and subsurface conditions observed, including the
    presence and transmissibility of groundwater and the instability of subsurface materials
    indicated by blockage. (Tr. 3/240-41) He concluded in his expert report that, even
    considering only the borings PBS&JC used, its analysis was unreasonable:
    Hence all six of the borings considered by the PBS&JC casing
    analysis that were drilled to the requisite pier foundation
    depth demonstrated either the presence of groundwater,
    instability of subsurface materials, or both, which would
    reasonably indicate the potential need for casing which should
    have been accounted for in the contractor's bid. Therefore,
    even considering only the borings PBS&JC used in their
    casing requirement analysis, a determination that casing
    would be needed in only 22 percent of the piers appears to be
    inadequately and unreasonably low.
    The PBS&JC pier casing analysis did not include the four
    other deep (foundation investigation) borings drilled during
    the [Corps] geotechnical subsurface investigation ... borings
    8A-5438, 3ST-5440, 3ST-5452, and 8A-5454. These borings
    should also have been considered by PBS&JC in the
    subsurface information analysis due to their proximity [to] the
    14
    project site. Out of the ten total deep borings, groundwater
    was noted in seven of the borings, while the remaining three
    were dry; blockage at various depths was also noted in the
    majority of the deep borings, indicating the presence of
    unstable materials. It is therefore reasonable to assume that
    100 percent of piers would require casing.
    (R4, tab 33 at 2; see also tr. 3/236-38, 250, 256-57 (GTR's borings demonstrated
    materials' permeable nature and their ability to transmit groundwater because 7of10 of
    deep borings were determined to have transmitted water and 10 of 10 indicated either
    groundwater or unstable materials as reflected by blockages.))
    42. Mr. McCleskey acknowledged that water's flow rate is potentially a factor in
    determining whether to case a pier. The GTR showed stable water levels, but the inflow
    rate could be variable. (Tr. 3/236)
    43. In Mr. McCleskey's expert opinion, job site conditions during drilling were
    similar to those indentified in the GTR's site field investigation (tr. 3/263-64). However,
    in the nature of fact evidence, he responded to questioning by PBS&JC's counsel that site
    conditions "could have been drier, but they could have been much wetter, and as we all
    know now, they turned out to be much wetter at that time" (tr. 3/261). The questioning
    mixed references to conditions at the time of PBS&JC's proposal compared to when the
    borings were taken and changes from the time of the proposal to the time of construction
    (tr. 3/259-61). We infer, in logical context, that Mr. McCleskey was referring to
    conditions at the time of pier drilling.
    44. Mr. McCleskey acknowledged that contractors were entitled to rely upon the
    GTR's boring logs. The Corps considered the GTR's information, including the number
    of borings drilled and the similarity of the subsurface conditions encountered, to be
    completely adequate for contractors' use in submitting their proposals. (Tr. 3/239,
    250-51, 260-61, 263-64)
    DISCUSSION
    As PBS&JC describes it, the "crux" of its differing site condition claim is:
    [T] he difference between the type ofgroundwater found in the
    borings, static water, and the immediate and continuous
    significant inflow of water which was discovered in the holes
    immediately upon drilling or shortly thereafter - a condition
    nowhere described in the [GTR].
    15
    The groundwater was a differing site condition not because it
    was encountered in 97% of the holes, but because of the
    immediacy, rate offlow, and quantity of the groundwater that
    was encountered which resulted in 97% of the holes being
    cased rather than pumped.
    (App. dsc resp. at 30, ~ 79, at 31, ~ 81)
    The Corps responds, inter alia, that there was no differing site condition and
    PBS&JC's alleged interpretation of the boring logs was unreasonable. The three sets of
    contemporaneous daily logs do not support its description of the crux of its claim.
    Further, PBS&JC has not met its burden to prove reliance because it did not produce any
    verifiable documentation that it evaluated the boring logs or considered the pier casing
    issue before it submitted its proposal and did not produce any witness who had first-hand
    knowledge of its alleged casing estimate, including who made it and when.
    To establish a Type I differing site condition PBS&JC must prove that:
    (1) [T]he contract contained positive indications of the
    conditions at the site; (2) it reasonably interpreted and relied
    upon the indicated site conditions; (3) the conditions
    encountered were materially different from those indicated;
    (4) the conditions encountered were reasonably unforeseeable
    based upon all the information available at the time of
    bidding; and (5) its injury was caused solely by the differing
    site condition.

    subsurface conditions. Nova Group, 10-2 BCA ~ 34,533 at 170,322.
    Regarding factor (1), the GTR and boring logs contained positive indications of
    site conditions. The GTR warned that "[g]roundwater should be anticipated during pier
    construction" and required the drilling contractor to have temporary steel casing and
    pumps on-site prior to drilled pier construction (finding 8). It listed 6 of the 19 borings at
    static water levels beginning at 11.8' and stated that the rest were dry or blocked.
    16
    Alliance's Mr. Rose acknowledged that blockage causes include water and loose soils and
    that water and blockage indicate a potential casing need. There were six borings within
    the building's footprint, of which two, 8A4C-5443 and 8A-5448, were not on the static
    water level list. At the logs' elevation groundwater section, 8A4C-5443 was stated to be
    dry but the log elsewhere showed water at 13.5' and the hole as blocked at 21.0'. Boring
    8A-5448 was indicated to be dry and showed no static water level, but the soil was
    described as slightly moist and very moist. (Findings 7, 9, 14)
    PBS&JC claimed that the borings were taken in two of the wettest months,
    December 2003 and January 2004, and represented a "worst case scenario" for
    groundwater conditions (finding 23). However, the RFP did not distinguish those months
    and anticipated adverse weather in many other months as well (finding 4).
    Concerning the reliance factor (2), the GTR provided, and the Corps
    acknowledges, that PBS&JC was entitled to rely upon the boring logs (findings 8, 44).
    However, the handwritten notes which PBS&JC cites for its alleged 22% pre-proposal
    casing estimate are undated, unsigned and anonymous. PBS&JC's senior project
    manager Williams speculated that they were from its preconstruction department, but he
    was not on the job until after contract award, was not involved in the casing estimate,
    could not recall any communications with its creator(s), and did not know who had
    arrived at the estimate or when. (Finding 25) Alliance was not given any casing estimate
    and, prior to the hearing, Mr. Eddins had never seen the notations on the boring logs
    (finding 26). Mr. Rose of Kleinfelder was not asked for any casing estimate and was not
    involved in PBS&JC's alleged estimate (finding 27). Drilling superintendent Herzog was
    not involved with any pier casing estimate for the project (finding 28).
    PBS&JC did not explain why it did not call anyone to testify who was involved in
    reaching its alleged casing estimate, for which we draw some adverse inference. See
    Maintenance Engineers, 
    ASBCA No. 52527
    , 01-2 BCA if 31,472 at 155,387. There is no
    contemporaneous evidence that the notes were prepared pre-proposal or of PBS&JC's
    pre-proposal assumptions about site conditions. It did not substantiate its claim that it
    reasonably interpreted and relied upon the GTR and boring logs, and arrived at a 22%
    casing estimate, prior to its submission of its proposal to the Corps. (Finding 29)
    Factor (3) requires a comparison of conditions encountered to those indicated in
    the contract and a determination of whether they were materially different. First, as we
    discussed under factor (1), the contract did indicate subsurface conditions. However, to
    prove a Type I differing site condition, PBS&JC must show that the contract contained
    some indication of the particular conditions at issue. As we have summarized:

    what is "indicated" in the contract. Foster Constr. C.A. and

    Mr. Eddins of Alliance acknowledged that that the soils at the lower depths were
    competent enough to pour a pier and were as represented in the GTR and that the
    subgrade materials were what the boring logs indicated. He believed that water caused
    the soil to become incompetent. (Finding 33) He also confirmed that the GTR and
    borings did not discuss the quantity of water or provide any information concerning the
    type of water flow a contractor could expect to en~ounter (finding 10).
    Ironically, as suggested in its description of the crux of its claim, which focused
    upon the rate of inflow of water, PBS&JC principally complains about the contract's
    alleged lack of site condition indications rather than incorrect indications or changes in
    the conditions (findings 10, 14, 15, 36). PBS&JC's counsel stressed this point in his
    opening statement:
    The [GTR] does not describe the water levels. It does
    not state how many casings the contractor must be prepared to
    use. It doesn't state the quantity or the flow rate [of] water,
    and it doesn't discuss anything with respect to expected
    infiltration into the site. None of that is in the [GTR].
    (Tr. 1/15-16)
    Regardless, Mr. McCleskey admitted that conditions were "much wetter" than they
    were when the borings were taken. We inferred that "much wetter" meant at the time of
    pier drilling. (Finding 43) Nevertheless, this alone does not trigger application of the
    differing site conditions clause. PBS&JC itself suggested that the cause of the additional
    water could be extreme weather. Drilling began on about 11August2010 and PBS&JC
    began to encounter water relatively soon thereafter that pumping did not resolve (findings
    18, 20), but Mr. Williams believed that a severe storm on 7-8 September 2010, in
    connection with compaction problems he attributed to a prior contractor, created
    18
    unsuitable material that directly related to the amount of water encountered during
    drilling (finding 19) However, "weather occurring during contract performance, no
    matter how severe, and other acts of God alone do not fall within the provisions of the
    Differing Site Conditions ... clause." Commercial Contractors Equipment, Inc., 
    ASBCA No. 52930
     et al., 03-2 BCA ii 32,381 at 160,255. Moreover, the differing site conditions
    clause protects a contractor from undisclosed or unknown site conditions that predate the
    contract, not something occurring thereafter. See John McShain, Inc. v. United States,
    
    375 F.2d 829
     (Ct. Cl. 1967) (addressing predecessor changed conditions clause);
    Commercial Contractors Equipment, 03-2 BCA ii 32,381 at 160,258.
    Factor (4) calls for PBS&JC to show that the conditions it encountered were
    reasonably unforeseeable based upon all the information available at the time of its
    proposal. Drilling superintendent Herzog opined that hitting groundwater on a drilling
    project and the use of casings were not unusual, but the amount of groundwater on the
    subject project was unusual (finding 35). Mr. Eddins of Alliance, who was not an expert
    witness, opined that less than 30% to about 31 % of the project borings indicated that
    water was present, fewer indicated sidewall instability, and a 22%-38% casing estimate
    would have been reasonable. According to his 21 December 2010 letter in support of
    PBS&JC's claim, over 90% of the piers had to be cased due either to excessive
    groundwater intrusion, side-wall instability, or both. Mr. Eddins noted at the hearing that,
    in a later Fort Hood project, the geotechnical report told contractors to assume that 100%
    of the piers would have to be cased. (Findings 10, 30-32, 34)
    However, as we have found, there is no contemporaneous evidence of PBS&JC's
    pre-proposal assumptions concerning site conditions (finding 29). According to expert
    McCleskey, PBS&JC's analysis of the boring logs as presented in its claim was not
    reasonable (findings 40, 41 ). Finally, although it did not specify a number of drill holes
    to be cased, the GTR for the subject project alerted prospective contractors that
    "groundwater should be anticipated during pier construction" and that casing and pumps
    were required on-site prior to drilled pier construction (finding 8). As Mr. Eddins
    acknowledged, ifthere is no direction concerning the number of piers to be cased, "you
    never know until you drill the hole" (finding 34).
    Thus, PBS&JC has not met the requirements to establish a compensable differing
    site condition set forth in factors (1)-(4). Factor (5) largely pertains to quantum, which
    we need not reach.

     to the extent relevant.
    45. SOW § 3 .1.1. prohibited exterior egress balconies (R4, tab 3 at 4 of 796), but
    § 6.2.1 stated: "Use of exterior wrap-around balcony is a deviation (approved by an
    existing waiver) from ... [§] 3.1.1." (id. at 42 of796). SOW§§ 3.2.3.6., 6.2.3., 6.5.1. and
    6.11.8. also refer to balconies for the barracks (id. at 10, 50-51, 59 of 796). Under SOW
    §§ 3.1.3.1. and 3.1.3.1.(a) gross building area was measured to the outside face of exterior
    closure walls. It included one half the area of exterior covered areas such as balconies,
    breezeways, exterior corridors, and porches, which were measured from the face of the
    enclosure wall to the edge of the covered area. (57964 R4, tab 8 at 24)
    46. RFP § 00 21 00 stated that "[s]pecial foundation work is required due to
    expansive soils found at Fort Hood" (R4, tab 3 at 5 of 106, if 1.1. ).
    4 7. Under RFP § 00 73 00, Special Contract Requirements (SCR), the contractor
    warranted that its design would meet contract requirements (R4, tab 3 at 20of39, §§ 1.7(a),
    1.8). SCR § 1.11, DEVIATING FROM THE ACCEPTED DESIGN (JUN 02), stated:
    (a) The Contractor shall obtain the approval of the Designer
    of Record [DOR] and the Government's concurrence for any
    Contractor proposed revision to the professionally stamped
    and sealed and Government reviewed and concurred design
    before proceeding with the revision.
    ( c) Any revision to the design, which deviates from the
    contract requirements (i.e., the [RFP] and the accepted
    proposal), will require a modification, pursuant to the
    Changes clause, in addition to Government concurrence. The
    Government reserves the right to disapprove such a revision.
    (R4, tab 3 at 22 of 39)
    48. RFP § 01 33 16, Design After Award [DAR], § 1.2., stated that the
    contractor's DOR is responsible for contract compliance (R4, tab 3 at 97, 100of796).
    Section 3.5.3.1. stated:
    20
    The contractor's licensed geotechnical engineer shall prepare
    a final geotechnical evaluation report, to be submitted along
    with the first foundation design submittal. This information
    should be made available as early as possible during the
    over-the-shoulder progress review process. The geotechnical
    report shall summarize the subsurface conditions and provide
    recommendations for the design of... foundations .... The
    [report] shall recommend foundation systems to be used ....
    (R4, tab 3 at 108 of 796)
    49. GTR § 5, "Discussions," stated:
    Development of the final foundation and pavement
    designs are [sic] the responsibility of the Design-Build
    Contractor and shall be in compliance with the requirements
    established herein. However, the Design-Build Contractor
    shall provide to the Government engineering studies and
    design calculations that support the· foundation and pavement
    design recommendations .... The Design-Build Contractor's
    foundation and pavement design recommendations shall be
    reviewed for technical adequacy and compliance with the
    criteria established in the [RFP], including this document.
    Specific requirements for the Design-Build Contractor's
    foundation and pavement design analysis are provided in
    section 5.f [Emphasis added]
    (R4, tab 4 at Bates 9) The referenced§ 5.f, "Requirements for the Design-Build
    Contractor's Foundation and Pavement Design Analysis," stated:
    (1) Recommended Foundation System(s).
    A foundation system consisting of reinforced concrete
    straight-shaft drilled piers shall be utilized for [the project}.
    The Design-Build Contractor shall design the straight-shaft
    drilled piers in accordance with the requirements and design
    parameters provided in this report. :{Emphasis added]
    (R4, tab 4 at Bates 24)
    21
    50. GTR § 5.b, "Foundation Design Considerations, Recommendations, and
    Requirements," stated:
    Based on the results of the geotechnical field investigation
    and laboratory testing program, and previous engineering
    experience at Fort Hood for similar buildings to those of the
    [project], the following recommendations, design parameters,
    and requirements are provided. For the size and type of the
    proposed facility to be constructed at Fort Hood as part of this
    project, and the site-specific subsurface conditions present, a
    reinforced concrete straight-shaft drilled pier foundation
    system is typically considered best-suited foundation system
    [sic]. Reinforced concrete straight-shaft piers have proven to
    be a highly successful foundation system at Fort Hood. A
    shallow foundation system consisting of reinforced concrete
    continuous and/or spot spread footings is not considered to be
    a viable alternative due to the presence of highly expansive
    and compressible clay overburden soils and fill materials and
    to the depth ofa competent bearing stratum beneath the
    overburden soils. Therefore, shallow footing and foundations
    are not allowed. [Emphasis added]
    (R4, tab 4 at Bates 11)
    51. GTR § 5.d(l) stated:
    Pavilions and other Small Support-type Structures. Covered
    Pavilions and any other small (<500 GSF) support-type
    structures (if applicable) can be supported on reinforced
    concrete slabs-on-grade.... It is further recommended that
    subgrade preparation ... consist of providing a minimum of 36
    inches of compacted nonexpansive fill below the
    soil-supported slab. [Emphasis added]
    (R4, tab 4 at Bates 15)
    52. The barracks are modular unit structures made of wood. The exterior balconies
    are described as 2- or 3-floored (balconies on second and third floors, covered walkway
    underneath). (Tr. 1142-43, 2/206, 3/126, 4/31, 113; see R4, tab 35 at Bates 7, Sheet S-000;
    exs. A-001, A-002) Shaddy Shafie, a lead structural engineer at Atkins, and a licensed
    structural engineer in several states and Puerto Rico, was the DOR (tr. 21132-37).
    Regarding G TR § 5.d(1) (finding 51 ), he acknowledged that the balconies were overall a
    22
    continuous system, over 500 gsf. However, for structural design loading criteria, he would
    break down the system into the balconies' columns. He thus deemed that the whole balcony
    system, regardless of the balconies' large size per floor, could be akin to a covered pavilion
    and a small support structure. (Tr. 2/207-08) Project superintendent Hartshorn proposed at
    the hearing that each column section involved about 300 square feet (tr. 3/150-51 ).
    Alliance's Mr. Rose considered the GTR's provision to be ambiguous as to whether the
    under 500 gsf limitation applied to covered pavilions (tr. 3/105). He stated that the balcony
    system could be construed to be a covered pavilion:
    Q      .. .Is it your testimony that three floors of
    balconies and covered walkways, consisting of thousands of
    square feet of area constitute a covered pavilion?
    A       Again, I'm not a structural engineer, but I don't
    see why it couldn't be construed that way.
    (Tr. 3/106)
    53. PBS&JC's proposal stated that the site preparation, "along with the foundation
    work (drilled piers and grade beams)," was scheduled for completion no later than 259
    days after the NTP (R4, tab 15, vol. 2, tab C, "Schedule Narratives" at 2). The parties
    agree that PBS&JC's proposal specified its intent to use a drilled pier foundation system
    beneath the barracks and did not indicate an intent to provide a design with exterior
    balconies (app. bp reply at 7, `` 36, 37).
    54. The Corps notified PBS&JC that its proposal was deficient due to the lack of
    exterior balconies. PBS&JC stated that its interpretation had been based upon SOW,
    § 3.1.1., prohibiting exterior egress balconies (finding 45). It incorporated the balconies
    into its design and submitted its best and final offer, prior to contract award on
    27 February 2009. (R4, tab 16 at Bates 3-7; app. bp reply at 8, ~ 43; finding 1)
    55. The Corps issued a Notice to Proceed for design work on 16 October 2009
    (app. hp reply at 9, `` 45, 46). PBS&JC submitted an interim foundation design dated
    30 November 2009. The parties agree that, under its proposal, the foundation was to be
    based upon drilled concrete piers, but its submittal advocated a "screw pile" foundation
    system and its drawings depicted the balconies and covered walkways supported on screw
    piles. (R4, tab 15B, Schedule Narratives at 2, tab 17 at 3-4; app. bp reply at 9, ~ 48, at 10,
    `` 51-52) Steel pipe screw piles are a proprietary deep foundation system that is less
    expensive than drilled piers, which are another type of deep foundation system, poured
    with concrete and reinforcing steel (tr. 1/94, 2/138, 3/124, 4/128).
    23
    56. PBS&JC and the Corps had several exchanges about screw piles, which the
    Corps disallowed (e.g., R4, tab 19 at Bates 2, tab 22 at Bates 70, tab 23). A 9 December
    2009 Kleinfelder report referred to the barracks as supported on screw piles and contained
    drawings depicting balconies and covered walkways supported by them (R4, tab 20 at 2-
    4, 46-47, tab 21). PBS&JC's "90% Foundation Submittal" of 27 April 2010 still had the
    barracks on screw piles, said to be based on a 26 April 2010 Kleinfelder report (R4, tab
    24 at 3, § 2.0 at 41). However, attached specifications covered "DRILLED CONCRETE
    PIERS AND SHAFTS" (id. at 5-6, § 02 47 00) and the report stated:
    3.2 Deep Foundation Recommendations
    Based on the subsurface conditions encountered at the test
    boring locations and the project information provided, we
    recommend the proposed buildings be supported on straight
    shaft drilled piers.... Design information for drilled piers is
    provided in the following sections. [Emphasis added]
    (R4, tab 24 at 47) The parties agree that Kleinfelder's report did not reference or propose a
    shallow foundation system for any of the project work and its design drawings showed
    balconies and covered walkways supported by concrete piers (R4, tab 25, Sheet Nos. S-101
    through S-115; app. bp reply at 13-14, iii! 68-70).
    57. PBS&JC submitted a final foundation design dated 2 June 2010, with
    Kleinfelder's revised 2 June 2010 Geotechnical Engineering Study. The parties agree
    that it mentioned, for the first time, the possibility of using spread footing foundations
    under certain conditions ifthe subgrade were prepared properly. (57964 R4, tab 9 at 61;
    app. bp reply at 15, iii! 77-78) PBS&JC did not proffer DOR Shafie as an expert witness.
    According to him, the referenced subgrade preparation was required with either spread
    footings or drilled piers and he understood that it had been prepared per the GTR
    (tr. 2/155, 169, 178). He acknowledged that PBS&JC's previous submittals had shown
    the dormitory, including balconies, supported on screw piles or drilled piers, two types of
    deep foundation systems (tr. 2/203; see similarly tr. 3/68 (Rose)). There is no evidence
    that PBS&JC had raised with the Corps any alleged ambiguities in the above contract
    provisions that contained the words "recommended" or "recommendations" as well as
    "requirements" or concerning GTR § 5.d(l)'s shallow foundation exception for small
    support-type structures (see findings 49-51 ).        ·
    24
    58. Kleinfelder's 2 June 2010 study stated:
    3.1    Expansive Soil and [C]onsolidation Considerations
    [A] PVR [Potential Vertical Rise] approaching 4 inches is
    expected. The estimated vertical movement [of the soil] is
    greater than what most structural engineers consider
    acceptable for a shallow foundation system.... [Emphasis
    added]
    3.2    Shallow Foundation Recommendations
    We understand that spread footings will be used at select
    locations within the proposed structure. This decision
    depends on many factors including the magnitude of soil
    movement expected, the type of structure, the intended use of
    the structure, the construction methods available to stabilize
    the soils, and the owner's expectations of the completed
    structure's performance. However, one should always expect
    a grade supported foundation to undergo some differential
    vertical movements.
    3.2.1 Building Pad Preparation
    Provided herein are subgrade preparation recommendations
    for spread footings to modify the magnitude of soil
    movements beneath grade supported structures at this site to
    approximately one (I) inch ....
    3.2.2 Spread Footings
    Shallow footings bearing on a properly prepared subgrade
    may be used to support the proposed structure ....
    (57964 R4, tab 9 at 67-69) However, the report's § 3.3, "Deep Foundation
    Recommendations" (id. at 69), repeated the drilled piers recommendation contained in
    Kleinfelder's 27 April 2010 report (finding 56). The parties agree that the drawings again
    showed balconies and covered walkways supported by concrete piers (R4, tab 29, Sheet
    Nos. S-101 through S-115; tr. 1/109-10, 2/135; app. bp reply at 16, ifif 84-85), and that
    PBS&JC's finalized July 2010 drawings again depicted concrete drilled piers under the
    covered walkways and balconies (R4, tab 35; app. bp reply at 16, if 83).
    25
    59. PBS&JC's Contract Drawing Sequence No. S-001 states:
    THE PROPOSED FOUNDATION DESIGN DEPICTED ON
    THE PLANS AND SECTIONS IS BASED ON THE FINAL
    UPDATED GEOTECH REPORT BY KLEINFELDER
    DATED 0610212010 INDICATING REQUIREMENT OF A
    DEEP FOUNDATION SYSTEM. THE DRAWINGS
    DEPICT GRAPHICALLY THE PROPOSED LOCATION
    OF DRILLED PIER. [Emphasis added]
    (R4, tab 35, Soil Preparation and Foundations, Note 1)
    60. On 2 July 2010 an ACO issued a Notice to Proceed, received by PBS&JC on
    9 July 2010, for construction of the finalized foundation design (ex. G-1).
    61. PBS&JC considered the lobby, entrance, mail kiosk, exterior walkways and
    balconies to be outside the main building. It sought to use spread footing foundations
    under them because it was behind schedule due to water and casing issues with the drilled
    piers, wanted to avoid them, and was looking to make up time and save costs, including
    potential liquidated damages. {Tr. 1/98-101, 3/195) By 14 October 2010 email to
    ACO Hammer, with the stated goal of improving the schedule, Paul Cook, PBS&JC's
    Director of Operations, submitted "Design Modification Request - RFI [Request for
    Information]-0119," seeking the Corps' "cursory review of our alternate foundation
    design intent" to remove drilled piers at the exterior balconies and replace them with
    spread footers, ''with the understanding that our designers will provide complete details
    and design calculations under separate correspondence for review and approval" (57964
    R4, tab 10 at Bates 149). He appended an internal PBS&JC RFI which inquired whether
    the change was viable or allowable. A PBS&JC structural engineer responded that it was
    viable. He included part of the 2 June 2010 Kleinfelder report (finding 57) and a sketch.
    (Id. at Bates 150; tr. 1/102-03) Mr. Cook told the ACO that one reason for the request
    was to speed up construction, but the ACO saw no benefit to the Corps in changing the
    contract (tr. 4/15, 41; Corps 12/19/12 resp. to APFF in 57964 (Corps bp resp.) at 28,
    ~ 271 ). There is no evidence that PBS&JC provided "complete details and design
    calculations" by separate correspondence or otherwise.
    62. The parties agree that the RFP had a separate design value for live loads for
    exterior walkways, balconies and stairs of 100 psf and that PBS&JC's structural engineers
    calculated that drilled piers under the balconies and walkways columns would carry a live
    load of 600 psf (Corps bp resp. at 7, `` 205, 206). DOR Shafie contended in a 24 January
    2012 memorandum that the foundations in the construction documents for the walkway
    columns were a "significant overdesign" (57964, compl., ex. 5). However, he
    acknowledged at the hearing that his firm had done the design and that load-bearing
    26
    capacity was not the only reason to use a drilled pier foundation system (tr. 2/227-28).
    Mr. Heinchon conceded that the design could have been "overkill" regarding load bearing
    issues, but he noted that the main reason for using drilled concrete piers at Fort Hood was
    its expansive soil. Tied in to the main structure, balconies with spread footings would tend
    to move a lot more than the rest of the structure. (Tr. 4/111, 115) Mr. Rose also
    acknowledged that one consideration for using a drilled pier foundation system is that, if
    properly supported, it is less likely to move than a shallow supported foundation (tr. 3/52).
    63. By 15 October 2010 email, Mr. Heinchon notified PBS&JC that the Corps'
    Geotechnical Section had responded that the GTR disallowed spread footings and
    required drilled concrete piers. By 22 October 2010 email to PBS&JC, he reiterated the
    disallowance and noted that PBS&JC's technical report had recommended straight shaft
    drilled piers. He stated that there was no need for PBS&JC to speak directly to the
    Geotechnical Section. (57964 R4, tabs 11, 12)
    64. By letter to PBS&JC of 28 October 2010, ACO Hammer reiterated that spread
    footings were disallowed and he directed PBS&JC to continue with concrete piers per its
    approved foundation design. However, he stated that the Fort Worth District's
    geotechnical engineer would be at Fort Hood on 1and2 November 2010 and available to
    speak to PBS&JC's geotechnical engineer if it so wished. PBS&JC declined because it
    felt a structural issue was involved and it proceeded with the drilled piers, which were
    well underway by the time it received the ACO's letter. (R4, tab 30; tr. 1/106-07)
    65. PBS&JC contends that it requested, and was denied, the opportunity to confer
    with a Corps structural engineer concerning spread footings. DOR Shafie testified:
    A      We submitted a letter and an RFI, requesting to
    use them at these locations, and requested to speak with a
    member of the Corps to discuss calculations and methods for
    making that system work, using spread foundations at the
    balconies and walkways.
    Q       Were you or anybody working for you on the
    structural team ever permitted or given the opportunity to
    speak with a Corps structural engineer or a Corps
    geotechnical engineer or otherwise provide the details and
    design calculations for the use of spread footers under the
    walkways and balconies?
    A      No.
    (Tr. 2/141) During cross-examination ACO Hammer testified:
    27
    Q       You said a moment ago that you spoke to your
    geotech section. Correct?
    A      Yes.
    Q      You never spoke to a structural engineer, did
    you?
    A      I don't believe so. No.
    Q      And you never took the contractor up on the
    contractor's offer to have its structural engineer speak with
    your structural engineer. Isn't that right?
    A      I don't- there was a lot of discussion where
    Paul Cook wanted- once he got our reply, what our reply was
    going to be or he got our letter, he wanted to meet with our
    geotech individuals. Okay. And he may have wanted to meet
    with our structural. We were going to entertain that. I think
    there were some emails back and forth.
    Whether that meeting took place, I don't know ....
    Q      And you don't recall- and I can show it to you
    if you don't-there was an email said, We're not going to let
    you talk to our geotech section?
    A      Well, I -there may have been that letter, and I
    don't deny that fact, but that didn't influence my decision.
    {Tr. 4/39-41) As noted, the Corps did arrange for PBS&JC's geotechnical engineer to
    meet with its geotechnical engineer but PBS&JC declined (finding 64). We have not
    found any written request by PBS&JC to speak to a Corps structural engineer or any
    corroborating evidence that the Corps denied any such request, whether written or oral.
    Thus, we find that PBS&JC has not substantiated its contention that the Corps refused to
    allow it to confer with a Corps structural engineer concerning its spread footings request.
    Also, we find no evidence that the Corps acted in any way to hinder or delay PBS&JC or
    to deprive it of the value of the contract.
    28
    66. By a 5 November 2010 RFI to the Corps, PBS&JC sought to use a reinforced
    concrete slabs-on-grade foundation for the mail kiosk based upon the GTR's provision
    that structures less than 500 GSF could be so supported (finding 51). The Corps
    responded that this was for stand-alone structures; otherwise the area must use the same
    foundation system as the structure to which it was connected. The kiosk did not qualify
    because it was structurally connected to the building. (R4, tab 32; see tr. 11112)
    Ultimately the Corps allowed spread footing foundations under the kiosk, a single story of
    qualifying small size. We are unpersuaded by project superintendent Hartshorn's
    calculation at the hearing that the kiosk's gsfwas 625 square feet (tr. 3/156-159).
    Regardless, the Corps essentially required PBS&JC to make the kiosk a separate structure
    by adding beams that created a building joint which resulted in a discontinuity between
    the two structures, and by constructing an expansion joint at the roofs interface to allow
    separate movement between the buildings. PBS&JC was behind schedule and the Corps
    thought this would help. ACO Hammer allowed the change without any further design
    review other than by the project engineer, any contract modification, or any request for
    money back from PBS&JC. (Ex. G-2; tr. 11112-13, 4/46, 72, 120, 122, 125)
    67. Drilling continued into mid November 2010. A total of 584 pier holes were
    drilled. (R4, tab 7B at Bates 222; app. dsc resp. at 17, ii 43)
    68. There was no contention that PBS&J's original drilled pier foundation design
    for the exterior balconies and walkways, which the Corps had approved, was defective.
    Although PBS&JC later contended that it was an over-design, it worked as intended and
    the Corps was satisfied with it. (Tr. 2/228-29, 4/118)
    69. By letter of 11February2011, Mr. Williams notified the Corps that PBS&JC
    would seek an equitable adjustment under the contract's Changes clause (57964 R4, tab 8
    at Bates 22). It submitted a certified $368,063 CDA claim dated 2 May 2011 to
    ACO Hammer, stating that its original proposal had deep foundations for the building
    consistent with the RFP but the Corps changed the building thereafter from internal
    corridors to an exterior balcony style building. PBS&JC alleged that, in its redesign, its
    engineering team "inadvertently added drilled piers to the exterior walkways" (id. at
    Bates 16), but the walkways were not an integral part of the building. They were exterior
    covered areas under SOW§ 3.1.3.1.(a) (finding 45), and application of the GTR's small
    structures provision (finding 51) was appropriate. PBS&JC noted that its DOR approved
    changing from drilled piers to spread footings under balcony columns and alleged that
    this was consistent with Kleinfelder's 2 June 2010 report concerning spread footings
    (findings 57, 58) and with SCR § 1.11 concerning deviations from accepted designs
    (finding 47). PBS&JC contended that its DOR's re-evaluation distinguished building and
    exterior balcony foundations, for which spread footings were a viable option. It stated
    that this design modification was within its contractual rights but, upon the Corps' refusal
    to allow it, it had installed drilled piers at the balcony footings per its original design. It
    29
    sought its alleged resulting additional costs. ( 57964 R4, tab 8 at Bates 16-17) There is no
    evidentiary support for PBS&JC's claim that drilled piers under exterior walkways had
    been added to its design "inadvertently."
    70. By final decision of 17 November 2011, the CO denied PBS&JC's claim and
    this timely appeal ensued (57964 R4, tabs 1, 2).
    Corps' Expert Evidence On Balcony Piers Claim
    71. Zachary Gerich, a licensed professional engineer, held a bachelor's of science
    degree in civil engineering and a master's degree in structural engineering. At the time of
    the hearing he was a senior structural engineer in the Fort Worth District's structural
    design s.ection. He was offered and admitted without objection as an expert in structural
    engineering. He submitted an expert report dated 18 July 2012. (R4, tab 34; tr. 4/48-51)
    72. In Mr. Gerich's opinion, GTR § 5.d.(1) (finding 51) applied to structures
    under 500 gsfthat were not part of a major structure-"more of a picnic-type structure,
    canopies, just anything that's not a major structure" (tr. 4/56). He described the balconies
    at issue as a three-story construction of steel framing with many methods of attachment to
    the building. He demonstrated that contract drawings showed that balconies and covered
    walkways were structurally integrated into the barracks through interconnected columns,
    beams, support angles, headed studs, and concrete decks. (Tr. 4/58-69)
    73. Based upon Mr. Gerich's expert testimony, the contract drawings, and
    DOR Shafie's acknowledgement that that the balconies were a continuous system over
    500 gsf, we find that the balconies and covered walkways were not under 500 gsf and did
    not qualify for the GTR § 5.d(l) exception to the contract requirement for a drilled
    concrete pier deep foundation system (findings 51, 52, 72, 76). We find the DOR's and
    Mr. Rose's propositions at the hearing that the balcony system could be akin to a covered
    pavilion and small support structure (finding 52) to be unreasonable and the Corps'
    interpretation to be the only reasonable one.
    74. Mr. Gerich opined that use of drilled pier shafts is to minimize movement
    within poor soils, such as the heave and shrinkage of the clays in the local Texas area.
    Piers are the main type of foundation that will eliminate any excessive movement in a
    structure. (Tr. 4/70) Corps expert McCleskey stated that the reinforced concrete straight
    shaft drilled pier foundation system was a project requirement due to the facility's design
    requirements, the subsurface conditions, and his and the Fort Worth District's previous
    design and construction experience for similar structures. The advantages of a drilled
    pier foundation system are that it extends below the soil's upper active zone that would
    tend to produce heave, expansion, consolidation, or settlement with a shallow foundation
    30
    system, and it can be extended to a deeper, higher bearing strength formation better able
    to support the anticipated design loads for the facility. (Tr. 3/243-44)
    75. Mr. Gerich similarly stated in his report that the GTR did not allow shallow
    foundations based upon the site's highly expansive and compressible clay soils. Potential
    heave in the upper 12' zone could be 2". Drilled shaft piers reduce potential swell and
    settlement to acceptable levels. Spread footings, however, will still move with the upper
    active soil zone. Movement can be reduced to tolerable levels only by extensive soil
    excavation and replacement with non-expansive fill. He also noted that Kleinfelder had
    recognized that there had to be extensive subgrade preparation, to minimize soil
    movement to about l ", if spread footings were used. However, in Mr. Gerich' s expert
    opinion, given that the balconies had a 5'-4" span, even I" of soil movement could affect
    their slope and function and would cause more structural issues, deterioration of the wood
    structures, and maintenance problems, in the future. (R4, tab 34 at 1-2)
    76. Citing contract drawings, Mr. Gerich reported that the balconies/covered
    walkways were effectively integrated into the dormitory structure and that, given the
    anticipated soil heave and that the balcony/walkway system was not designed to move
    independently of the main structure, a common foundation system was required. In his
    opinion a structural designer should not mix different structural systems within a
    structure; use of different foundation types requires isolation joints at the intersection of
    the different systems; and the attachment of the balcony to the building structure would
    undergo severe deformations. The worst scenario would be differential settlement of the
    individual footings, which would damage the balcony and building connection and the
    connection between the exterior balcony columns. Mr. Gerich described in detail the
    potential problems with using spread footings instead of drilled piers for the
    balcony/walkways, including, inter alia, that the entire balcony structure would need to be
    isolated from the building, with enough clearance to prevent interference due to
    settlement and additional footings to support the balconies properly. (R4, tab 34 at 2-4)
    Mr. Gerich acknowledged at the hearing that it was possible, "[w ]ith a complete
    redesign," to design a separate structure for the balconies that would have allowed
    differential movement between them and the building (tr. 4/82).
    DISCUSSION
    PBS&JC contends that the Corps improperly denied its request to use shallow
    footings under the balconies and exterior walkways, which the contract allowed and was
    not a design deviation, as demonstrated by the Corps' acceptance of a shallow foundation
    at the mail kiosk. Alternatively, the contract was ambiguous as to whether the spread
    footers could be used and it should be construed against the Corps. PBS&JC apparently
    alleges latent ambiguities. Further, the Corps acted arbitrarily and capriciously and
    breached its duty of good faith and fair dealing when it failed to cooperate with PBS&JC
    31
    in its request to use spread footings and to administer the contract in a manner that did not
    hinder or delay performance or increase its cost.
    The Corps responds that the contract was not ambiguous; it expressly required
    deep foundation systems and disallowed shallow footings for the balconies and exterior
    walkways; and the Corps was entitled to strict compliance. The Corps contends that
    PBS&JC's claimed interpretations were not reasonable and it did not rely upon them prior
    to contract award. Lastly, the Corps asserts that it administered the contract reasonably
    and did not breach its duty of good faith and fair dealing.
    Regarding contract requirements for foundations, the GTR stated that the
    contractor's foundation and pavement designs were to comply with the RFP's and GTR's
    requirements and that specific requirements were in GTR § 5.f. That section,
    "Requirements for the Design-Build Contractor's Foundation and Pavement Design
    Analysis," stated under~ (I), "Recommended Foundation System(s)," that a reinforced
    concrete straight-shaft drilled pier foundation system "shall be utilized" and the
    contractor "shall design the straight-shaft drilled piers" in accordance with the GTR
    (finding 49). GTR § 5.b, "Foundation Design Considerations, Recommendations, and
    Requirements," stated that a "shallow foundation system" of "reinforced concrete
    continuous and/or spot spread footings" was "not considered to be a viable alternative"
    and "shallow footings" were "not allowed" (finding 50).
    The GTR § 5.d(I) exception at issue applied only to covered pavilions and "any
    other small (::;500 GSF) support-type structures" (finding 51). It thus equated covered
    pavilions with "other" small support-type structures, all of which had to be equal or less
    than 500 gsf. We have found that the balconies and covered walkways were not under
    500 gsf, did not qualify for the small structure exception, and that the DOR's and
    Mr. Rose's propositions at the hearing that the balcony system could be akin to a covered
    pavilion and small support structure were unreasonable (finding 73).
    PBS&JC's actions confirm that it interpreted the RFP to require a deep foundation
    system when it submitted its accepted proposal and for a long time after contract award.
    After some initial confusion on its part as to whether exterior balconies were required,
    PBS&JC incorporated exterior balconies into its design prior to contract award (findings
    53, 54). The accepted proposal design showed a foundation based upon drilled concrete
    piers-a deep foundation system (finding 55). PBS&JC alleged in its claim that, in its
    re-design, its engineers had "inadvertently added drilled piers to the exterior walkways,"
    but there is no evidentiary support for the claim of inadvertence (finding 69). PBS&JC's
    interim design submittal of 30 November 2009 and designer Kleinfelder's 9 December
    2009 report, both post-contract award, each depicted balconies and covered walkways
    supported on screw piles, another deep foundation system. Kleinfelder's 26 April 2010
    report recommended a straight shaft drilled pier foundation system, did not propose a
    32
    shallow foundation system for any of the project work, and its design drawings showed
    balconies and covered walkways supported by concrete piers. (Findings 55-57)
    Kleinfelder' s 2 June 2010 geotechnical engineering study mentioned the
    possibility of spread footing foundations for the first time, stating it understood they
    would be used at select locations, and that they could be used on a proper subgrade.
    However, the report also stated that the soil's estimated vertical movement was "greater
    than what most structural engineers consider acceptable for a shallow foundation system,"
    repeated the drilled piers recommendation in the 26 April 2010 report, and contained
    drawings showing balconies and covered walkways on concrete piers. (Finding 58)
    PBS&JC's finalized July 2010 drawings again depicted concrete drilled piers under the
    covered walkways and balconies (findings 58, 59). It was not until 14 October 2010 that
    PBS&JC submitted a "Design Modification Request" to remove drilled piers at the
    exterior balconies and replace them with spread footers (finding 61 ).
    In sum, it is apparent that the contract did not allow the use of shallow spread
    footings under the exterior balconies and walkways, and that is how PBS&JC interpreted
    it for much of the contract performance period.
    Regarding PBS&JC's alternative ambiguity argument, a contract provision is
    ambiguous only if it is susceptible of more than one different, reasonable, interpretation.
    Metric Constructors, Inc. v. NASA, 
    169 F.3d 747
    , 751 (Fed. Cir. 1999); Edward R.
    Marden Corp. v. United States, 
    803 F.2d 701
    , 705 (Fed. Cir. 1986). While we have found
    the Corps' interpretation of the exception allowing shallow foundations for small
    structures to be the only reasonable one (finding 73), even if we were to assume that there
    is another reasonable interpretation, PBS&JC cannot recover because any ambiguity
    would be patent and it failed timely to inquire about it. A patent ambiguity is one that
    would be apparent to a reasonable person in the claimant's position. In such a case, the
    contractor has a duty to inquire of the government about the provision's meaning before it
    submits its bid or proposal. The issue of whether a contractor's particular interpretation is
    reasonable is reached only if the ambiguity is not patent. Lockheed Martin IR Imaging
    Systems, Inc. v. West, 
    108 F.3d 319
    , 322 (Fed. Cir. 1997); Newsom v. United States, 
    676 F.2d 647
    , 649 (Ct. Cl. 1982); Dick Pacific/GHEMM, JV, ASBCA Nos. 54743, 55255,
    09-2 BCA if 34,178 at 168,965.
    PBS&JC knew, prior to its final proposal submission, and before contract award,
    that the contract included exterior balconies (finding 54). PBS&JC's alleged
    interpretations and ambiguities advanced at hearing or in briefing are strained. It alleges
    that there are ambiguities to the extent that any of the relevant contract provisions
    contained the words "recommended" or "recommendations" as well as "requirements"
    (see findings 49, 50), or that the 500 psf reference in the shallow foundation exception
    could be read not to apply to covered pavilions, or not to apply when individual column
    33
    sections were under 500 gsf (see findings 51, 52 ). However, any such alleged
    ambiguities were obvious. PBS&JC should have timely raised them and it did not
    (finding 57). Therefore, the alleged ambiguities are resolved against it. P.R. Burke Corp.
    v. United States, 
    277 F.3d 1346
    , 1355 (Fed. Cir. 2002). Because the ambiguities alleged
    by PBS&JC were patent, we do not reach any latent ambiguity arguments.
    With respect to PBS&JC's contention that the Corps acted arbitrarily and
    capriciously in denying its request to use spread footings under the exterior balconies and
    covered walkways, the Corps' actions were sanctioned under the contract. It required that
    the contractor obtain the government's concurrence for any proposed revision to the
    approved design before proceeding, and the government reserved the right to disapprove
    any design revision that deviated from contract requirements. (Finding 47)
    PBS&JC alleges that the spread footings change was not a deviation from contract
    requirements and notes that the Corps allowed spread footing foundations under the mail
    kiosk, without any contract modification. However, the mail kiosk was a single story of
    qualifying small size, which PBS&JC in essence made a separate structure. (Finding 66)
    Although Mr. Gerich acknowledged that it was possible to design a separate structure for
    the balconies that would have allowed differential movement between them and the
    building, this would have required a complete redesign (finding 76). Moreover, while the
    requirement for drilled piers under the balconies "'nd walkways could have been more
    than was necessary for load-bearing purposes, the main reason for using drilled concrete
    piers at Fort Hood was its expansive soils. Balconies with spread footings would tend to
    move a lot more than the rest of the structure to which they were tied. Mr. Rose of
    Kleinfelder acknowledged that a drilled pier foundation system is less likely to move than
    a shallow supported foundation. Expert Mr. Gerich confirmed that drilled piers were
    used to minimize movement within poor soils, such as those in the local Texas area, and
    that spread footings would move. (Findings 62, 74, 75)
    The Corps was entitled to compliance with its specifications and the approved
    design, and saw no benefit to it in changing. It was not obligated to approve a change,
    particularly such a significant one, advanced by PBS&JC for the first time relatively late
    in the project. (Findings 57, 61, 68) Thus, the Corps did not act arbitrarily and
    capriciously in denying PBS&JC's request to use spread footings under the balconies and
    covered walkways.
    Somewhat intertwined with its contentions that the Corps acted arbitrarily and
    capriciously, PBS&JC further alleges that the Corps breached its duty of good faith and
    fair dealing and its duty not to hinder or delay contract performance by failing to
    cooperate with it in its request to use spread footings. PBS&JC particularly stresses the
    Corps' alleged refusal to allow it to confer with a Corps structural engineer.
    34
    The duties to cooperate and not to hinder have been treated as aspects of the duty
    of good faith and fair dealing. Metcalf Construction Co. v. United States, 
    742 F.3d 984
    ,
    991 (Fed. Cir. 2014). Government officials are presumed to act in good faith and it takes
    clear and convincing evidence to prove otherwise. Road and Highway Builders, LLC v.
    United States, 
    702 F.3d 1365
    , 1368-69 (Fed. Cir. 2012). In Metcalf, the court of appeals
    discussed governmental breach of the duty of good faith and fair dealing in terms of acts
    or omissions that, while not expressly proscribed by the contract, are inconsistent with its
    purpose and deprive the other party of the contract's contemplated value. 742 F.3d at
    991; accord Century Exploration New Orleans, LLC v. United States, 
    745 F.3d 1168
    ,
    1179 (Fed. Cir. 2014). The court recently summarized:
    Every contract implicitly contains a covenant of good
    faith and fair dealing, keyed to the obligations and
    opportunities established in the contract. The covenant
    imposes on each party a "duty not to interfere with the other
    party's performance and not to act so as to destroy the
    reasonable expectations of the other party regarding the fruits
    of the contract."
    Lakeshore Engineering Services, Inc. v. United States, 
    748 F.3d 1341
    , 1349 (Fed. Cir.
    2014) (citations omitted).
    PBS&JC stated in its 14 October 2010 request to change its approved design in
    order to use shallow spread footings under the exterior walkways and balconies, rather
    than deep foundation concrete drilled piers, that it would provide complete details and
    design calculations. There is no evidence that it did so. (Finding 61) The Corps notified
    PBS&JC that its Geotechnical Section had disallowed the change. While, at first, it stated
    that there was no need for PBS&JC to speak directly to the Section, the Corps later
    arranged for a meeting if PBS&JC so wished. PBS&JC declined because it felt a
    structural issue was involved and it was well underway with the drilled piers at the time.
    (Findings 63, 64) We found that PBS&JC did not substantiate its contention that the
    Corps refused to allow it to confer with a structural engineer concerning its spread
    footings request and we found no evidence that the Corps acted in any way to hinder or
    delay PBS&JC or to deprive it of the value of the contract (finding 65).
    In sum, there is no evidence that the Corps' actions were in any respect tantamount
    to a breach of its duty of good faith and fair dealing.
