ORDER AND OPINION

DIETZ, Judge.

Thalle Construction Company, Inc. (“Thalle”) protests a decision by the U.S. Army 

Corps of Engineers (“Corps”) to award a contract for canal construction to Phillips & Jordan, 

Inc. (“P&J”). Thalle challenges the Corps’ assessment of several significant weaknesses and 

weaknesses against Thalle’s proposal, as well as its assessment of several strengths to P&J’s 

proposal. Thalle alleges that the Corps applied unstated evaluation criteria, failed to engage in 

clarifications, and treated Thalle’s and P&J’s evaluations unequally. Because the Court finds that 

the Corps’ evaluation of Thalle’s proposal was arbitrary and capricious, Plaintiff’s motion for 

judgment on the administrative record is GRANTED. Defendant and Defendant-Intervenor’s 

respective cross-motion are DENIED. The Corps is ENJOINED from proceeding with 

performance of the contract awarded to P&J until the Corps completes a reevaluation of Thalle’s 

proposal consistent with this Opinion.

I. BACKGROUND

A. Overview of the Solicitation 

The Corps issued Solicitation No. W912EP-21-R-0024 (“Solicitation”) for the 

construction of a seepage canal and an inflow/outflow (“I/O”) canal in the Everglades 

Agricultural Area, as part of the Central Everglades Planning Project in Palm Beach County, 

Florida. AR 2.

2 The Solicitation called for a Federal Acquisition Regulation (“FAR”) Part 15

competitively negotiated source selection. Id. The Solicitation contemplated a firm-fixed price 

contract. AR 10. The Solicitation identified four evaluation factors: Technical Merit, Past 

Performance, Small Business Participation, and Price. AR 13. Technical Merit is the only 

evaluation factor at issue in this protest. 

The Basis of Award section of the Solicitation stated that an “award will be made [to] the 

best overall (i.e., best value) proposal that is determined to be the most beneficial to the 

[g]overnment, with appropriate consideration given to the four evaluation factors.” AR 13. The 

Contracting Officer was to evaluate proposals “us[ing] a trade-off process to determine which 

offer represents the best value to the [g]overnment.”

3

Id. Additionally, the Solicitation provided 

that “[a]ll evaluation factors other than price, when combined, are approximately equal to price”

for the purpose of the tradeoff analysis. Id. However, the Solicitation further provided that “[t]o 

receive consideration for award, a rating of no less than ‘Acceptable’ must be achieved for the 

Technical Merit [f]actor.” Id.

The Solicitation stated that the objective of an offeror’s response to the Technical Merit 

factor “should be to instill confidence that the offeror thoroughly understands the requirements 

of the [S]olicitation, [and] has the expertise and experience required to successfully satisfy or 

2 The Court cites to the Administrative Record, filed by the government at ECF No. 22 as “AR ___.”

3 The FAR establishes when a tradeoff process is appropriate and sets forth requirements for the conduct of a 

tradeoff process. See FAR 15.101-1.
3

exceed the [S]olicitation requirements within the required period of performance[.]” AR 14. The 

Solicitation instructed that “[t]he [g]overnment will not make assumptions concerning intent, 

capabilities, or experiences” and that “[c]lear identification of proposal details shall be the sole 

responsibility of the offeror.” AR 14. Additionally, “[o]fferors should also identify potential risks 

and plans for mitigating those risks.” AR 15.

The Technical Merit factor consisted of two elements—Technical Approach Plan and 

Construction Schedule. AR 13. The Technical Approach Plan element required offerors to 

describe the way they would “execute the work from start to completion.” AR 15. This element 

specified minimum requirements for the Technical Approach Plan and stated that the proposed 

plan would be evaluated based on “the degree to which the offeror’s proposal meets the 

requirements of the solicitation as well as the feasibility of the proposed approach.” AR 15-16. 

The Construction Schedule element required the offeror to submit a schedule “showing the start 

and completion dates, interdependence, and other relative scheduling factors for all the items 

listed in Element 1 above.” AR 16. Both elements stated that “[a]ny conflicts between Element 1 

and Element 2 may be noted as a weakness.” Id. However, the Solicitation explained that 

“[e]lements are not rated separately.” AR 15. Each member of the Source Selection Evaluation 

Board (“SSEB”) would individually rate each proposal against the Solicitation evaluation 

criteria, and “[a]n overall rating w[ould] be assigned for Factor 1 – Technical Merit” based on 

the SSEB reaching a consensus on an adjectival rating. AR 15-16. The five adjectival ratings

available to the SSEB were Outstanding, Good, Acceptable, Marginal, and Unacceptable, as 

defined below. AR 17-18.
4

Id. The assignment of an overall rating included “consideration of risk in conjunction with the 

strengths, weaknesses, significant weaknesses, uncertainties, and deficiencies” and “reflect[ed] 

the [g]overnment’s confidence in each offeror’s technical ability, as demonstrated in its proposal, 

to perform the requirements stated in the [Solicitation].” AR 17. 

B. The Evaluation, Award Decision, and Protest

The Corps received five proposals, including those from Thalle and P&J. AR 3463, 3773.

Of the proposals, only P&J’s proposal received a Technical Merit rating of Acceptable or better.

See AR 2141-68. Thalle and P&J received the following ratings:

AR 2172. Thalle’s Marginal rating on Technical Merit was based on the SSEB’s assignment of

no significant strengths, six strengths, five significant weaknesses, and seven weaknesses. See 

AR 2164-66.

The SSEB presented its findings to the Contracting Officer, who also served as the

Source Selection Authority (“SSA”) for this procurement. AR 2141-68. The SSA made the

award decision without discussions “because only one awardable proposal was received, and that 

proposal was in the awardable price range.” AR 2193. The SSA determined that P&J represented 

“the best value offer providing the highest rated Technical Merit with all other factors essentially 

being rated equal.” Id. The SSA recognized that while “there were other offerors with pricing 

lower than [P&J], their price is still $803,296.30 below the [Independent Government Estimate 

(“IGE”)].” Id. P&J’s price was deemed fair and reasonable based on adequate price competition

and comparison to the IGE. Id.

Thalle filed its complaint in this Court on December 6, 2021, alleging that the Corps 

failed to evaluate Thalle’s proposal in accordance with the Solicitation, failed to seek 
5

clarifications, and treated offerors unequally. 4 Compl., ECF No. 1. The parties subsequently 

filed cross-motions for judgment on the administrative record, and oral argument was held on 

March 22, 2022. Thalle’s protest is ripe for decision.

II. LEGAL STANDARDS

The Tucker Act grants this Court authority to render judgment on an action “by an 

interested party objecting to . . . any alleged violation of statute or regulation in connection with 

a procurement.” 28 U.S.C. § 1491(b)(1) (2018). The Tucker Act’s waiver of sovereign immunity 

“covers a broad range of potential disputes arising during the course of the procurement process” 

including objections to an award. Sys. Application & Techs., Inc. v. United States, 691 F.3d 

1374, 1380 (Fed. Cir. 2012). Accordingly, Thalle’s challenge to the Corps’ award of a contract to

P&J is within this Court’s subject-matter jurisdiction.5

Under Rule 52.1 of the Rules of the United States Court of Federal Claims, a party may 

file a motion for judgment on the administrative record to assess whether a federal administrative 

body acted in accordance with the legal standards governing the decision under review. Agile 

Def., Inc. v. United States, 143 Fed. Cl. 10, 17 (2019). This motion “is often an appropriate 

vehicle to scrutinize an agency’s procurement actions because such cases typically involve 

interpretation of contract documents or regulations, thereby presenting no disputed issues of 

material fact.” Banknote Corp. of Am., Inc. v. United States, 365 F.3d 1345, 1352 (Fed. Cir. 

2004). On a motion for judgment on the administrative record, the parties are limited to the 

administrative record, and the court makes factual findings as if it were conducting a trial on the 

record. Bannum, Inc. v. United States, 404 F.3d 1346, 1357 (Fed. Cir. 2005). This Court’s 

inquiry is “whether, given all the disputed and undisputed facts, a party has met its burden of 

proof based on the evidence in the record.” A&D Fire Prot., Inc. v. United States, 72 Fed. Cl. 

126, 131 (2006).

This Court reviews agency decisions in bid protests using the standard of review set forth 

in the Administrative Procedure Act (“APA”). 28 U.S.C. § 1491(b)(4); Impresa Construzioni 

Geom. Domenico Garufi v. United States, 238 F.3d 1324, 1332 (Fed. Cir. 2001). This standard 

permits a court to set aside an agency’s contracting decision if the protestor shows it is 

“arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with law.” 5 U.S.C. 

§ 706(2)(A) (2018); Bannum, 404 F.3d at 1351. “Under an arbitrary or capricious standard, the 

reviewing court should not substitute its judgment for that of the agency[] but should review the 

basis for the agency decision to determine if it was legally permissible, reasonable, and 

supported by the facts.” Glenn Def. Marine (Asia), PTE Ltd. v. United States, 105 Fed. Cl. 541, 

559 (2012), aff’d, 720 F.3d 901 (Fed. Cir. 2013) (citing Motor Vehicle Mfrs. Ass’n of U.S., Inc. v. 

State Farm Mut. Auto. Ins. Co., 463 U.S. 29, 43 (1983)). The protestor has the burden to show by 

a preponderance of evidence the arbitrary and capricious nature of the agency decision. Mortg. 

4 Thalle initially filed its protest at the Government Accountability Office (“GAO”). AR 2375-96. GAO dismissed 

Thalle’s protest after Thalle opted to file a complaint in this Court. See AR 3639-41. 

5 None of the parties to this litigation challenge the Court’s jurisdiction over this case or Thalle’s standing to bring 

its protest. Nonetheless, the Court “has an obligation to satisfy itself that jurisdiction is proper[.]” L-3 Commc’ns. 

Corp. v. United States, 99 Fed. Cl. 283, 288 (2011) (citing Hertz Corp. v. Friend, 559 U.S. 77, 130 (2010)).
6

Contracting Servs., LLC v. United States, 153 Fed. Cl. 89, 124 (2021). While the APA standard 

calls for considerable deference to the agency, PAI Corp. v. United States, 614 F.3d 1347, 1351 

(Fed. Cir. 2010), a court may set aside an agency’s procurement decision if the decision lacked a 

rational basis, or the procurement procedure involved a violation of regulation or procedure. 

Impresa, 238 F.3d at 1332; see also Safeguard Base Operations, LLC v. United States, 989 F.3d 

1326, 1343 (Fed. Cir. 2021). Nevertheless, if the reviewing court finds that the agency’s action 

evinced rational reasoning and consideration of relevant factors, it must sustain the agency’s 

action. Advanced Data Concepts, 216 F.3d at 1058 (citing Bowman Transp., Inc. v. ArkansasBest Freight Sys., Inc., 419 U.S. 281, 285-86 (1974)).

An agency decision is arbitrary and capricious when it results from unequal treatment of 

the offerors. See CliniComp Int’l Inc., v. United States, 117 Fed. Cl. 722, 742 (2014) (stating 

“[U]nequal treatment is fundamentally arbitrary and capricious, and violates . . . full and open 

competition[.]”). A claim of unequal treatment is derived from the FAR requirement that “[a]ll 

contractors and prospective contractors shall be treated fairly and impartially but need not be 

treated the same.” FAR 1.102-2(c)(3). An offeror is treated unequally when “the agency 

unreasonably downgraded its proposal for deficiencies that were ‘substantively 

indistinguishable’ or nearly identical from those contained in other proposals.” Office Design 

Grp. v. United States, 951 F.3d 1366, 1372 (Fed. Cir. 2020). If a protestor demonstrates that the

relevant proposals were substantively indistinguishable, a reviewing court may compare and 

analyze “the agency’s treatment of proposals without interfering with the agency’s broad 

discretion in these matters.” Id.

An agency decision is also arbitrary and capricious if the decision is a product of the 

agency’s application of unstated evaluation criteria. See NVE, Inc. v. United States, 121 Fed. Cl. 

169, 180 (2015) (stating that an offeror can challenge an agency’s analysis as “arbitrary, 

capricious, or an abuse of discretion” when the agency relies on unstated evaluation criteria). A 

claim that an agency relied upon unstated evaluation criteria in the evaluation of a proposal is 

based on instruction in the FAR that “[a]n agency shall evaluate competitive proposals and then 

assess their relative qualities solely on the factors and subfactors specified in the Solicitation.” 

FAR 15.305(a). To succeed on an unstated evaluation criteria claim, “a protester must show that: 

(i) the procuring agency used a significantly different basis in evaluating the proposals than was 

disclosed; and (ii) the protestor was prejudiced as a result—or, in other words, that it had a 

substantial chance to receive the contract award but for that error.” Banknote Corp. of Am., Inc. 

v. United States, 56 Fed. Cl. 377, 387 (2003), aff’d, 365 F.3d 1345 (Fed. Cir. 2004).

III. DISCUSSION

In its protest, Thalle argues that the Corps performed an arbitrary and capricious proposal 

evaluation because it treated Thalle’s proposal unequally, applied unstated evaluation criteria, 

and failed to seek clarifications. Thalle specifically challenges the Corps’ assessment of five 

significant weaknesses and seven weaknesses to its proposal, as well as its failure to assess three 

strengths to its proposal. But for the Corps’ faulty evaluation, Thalle asserts that its proposal 

would have received a higher Technical Merit rating, been subject to a best-value tradeoff 

analysis, and, because of its lower price, ultimately been selected for contract award. Based on 

the administrative record, the Court finds that the Corps’ assessment of two significant 
7

weaknesses and two weaknesses against Thalle’s proposal was arbitrary and capricious. The 

Court also finds that the Corps’ failure to assess one strength to Thalle’s proposal was arbitrary

and capricious. 

A. The Corps’ assessment of two significant weaknesses and two weaknesses

and its failure to assess one strength to Thalle’s proposal was arbitrary and 

capricious.

1. The Corps’ assessment of a significant weakness because Thalle identified 

two different subcontractors to perform blasting was not arbitrary or 

capricious. 

The Corps assessed a significant weakness to Thalle’s proposal because it “identifie[d] 

two different subcontractors to perform drilling & blasting (Contract Drilling & Blasting 

[(“CD&B”)] as well as Florida Energy).” AR 2164. The Solicitation provided that “a letter of 

commitment must be provided for any proposed major subcontractor for . . . rock blasting.” AR 

928. A major subcontractor is defined as “any subcontractor whose experience is submitted as 

part of the proposal.” Id. The Solicitation also required that offerors “demonstrate that [it] and/or 

[its] major subcontractors have experience . . . successfully performing blasting operations.” AR 

18.

Thalle included letters of commitment from Florida Energy and CD&B as blasting 

subcontractors in its proposal. AR 1288-90. In the blasting narrative portion of its proposal, 

Thalle referred only to Florida Energy as its blasting subcontractor. See AR 1301 (“Thalle will 

be partners with Florida Energy”). In contrast, Thalle referred only to CD&B to demonstrate its 

blasting experience. AR 1349-57 (CD&B’s blasting experience). In its evaluation, the Corps 

explained that this discrepancy makes it “unclear who [Thalle] intends to use and therefore 

conflicts with the project blasting plan.” AR 2164. 

Thalle argues that “the Solicitation did not prohibit offerors from providing letters of 

commitment from multiple subcontractors for the same work.” Pl.’s Mem. in Supp. of Mot. for J. 

on Admin. R. at 29, ECF No. 23-1 [hereinafter Pl.’s Mem.]. This argument is not persuasive. The 

record shows that the Corps assessed this significant weakness, not simply because Thalle 

submitted two letters of commitment from different subcontractors, but because it is unclear 

from Thalle’s proposal which subcontractor would be used for blasting. AR 2164. The Court 

agrees that Thalle’s proposal is unclear. Thalle’s submission of the two letters of commitment, 

combined with its use of Florida Energy in its blasting narrative and reliance on CD&B for its 

past performance, creates an ambiguity in the proposal. It is not the Corps’ obligation to resolve 

such ambiguity. See AR 14 (“The [g]overnment will not make assumptions concerning intent,

capabilities, or experiences . . . . Clear identification of proposal details shall be the sole 

responsibility of the offeror”). Considering the importance of blasting subcontractors to the 

overall project and the Corps’ stated requirement to demonstrate experience performing 

successful blasting operations, the Corps reasonably viewed this ambiguity as a concern and 

assigned a significant weakness to Thalle’s proposal for its perceived increased risk of 

unsuccessful performance. AR 17, 2164. 
8

2. The Corps’ assessment of a significant weakness for Thalle’s proposed 

equipment resources was not arbitrary or capricious. 

The Corps assessed another significant weakness because the equipment resources 

included in Thalle’s proposal “are unclear for loading and hauling[.]” AR 2164. The Solicitation 

required that offerors “[p]rovide typical production rates for all listed equipment planned to be 

utilized to blast, excavate, remove, transport, crush, process, place, and stockpile material.” AR 

15. In the planned equipment portion of Thalle’s proposal, it states that Thalle will use “two 

spreads per canal.” AR 1296. It further explains that:

Thalle will utilize two independent loading spreads that each include Two 349 

excavator and Eight 40 ton off road trucks, with each canal having a D6 dozer for 

cleanup. This equipment spread will maintain 376 [cubic yards (“CY”)] per hour, 

which in combination will maintain 1,128 CY per hour, or 11,280 CY per shift. 

This production rate provides for enough float in the schedule to account for 

downtime, weather, equipment maintenance, or environmental stoppages but not 

exceed the 530 feet per week allowed. 

AR 1297. The Corps assessed a significant weakness, explaining that “[Thalle] states two 

independent spreads; however, 2*346 CY per hour is 346 CY short of 1,128 CY and it is 

unknown if [Thalle] intends to use three independent spreads or two.” 6, 7 AR 2164. The Corps 

further explained that “[i]f [it is] two, [then] it does not appear to be enough production resources 

to meet the schedule.” Id.

The Court agrees that Thalle’s proposal is unclear mathematically. Thalle proposed to use 

two spreads per canal, each with two excavators and additional equipment. Thalle’s proposal 

stated that each “equipment spread will maintain [a rate of] 376 CY per hour.” AR 1297 

(emphasis added). At that rate, three spreads would be required to equal Thalle’s proposed total 

production rate of 1,128 CY per hour. Thalle’s proposed equipment usage thus falls short of its 

proposed total production rate. Even if the Corps understood Thalle’s proposed individual rate to 

apply to each excavator rather than each equipment spread (which is notably different from the 

language in the proposal), as Thalle now argues it intended, there would still be a mathematical 

discrepancy. Four excavators operating at Thalle’s proposed individual rate would result in a 

total rate of 1,504 CY per hour. Thalle now explains that it arrived at 1,128 CY per hour by 

applying a 75% productivity rate to account for downtime. Pl.’s Mem. at 30. This explanation, 

however, is not contained anywhere in Thalle’s proposal, and the Corps is not obligated to make 

assumptions regarding Thalle’s intentions with respect to its proposed equipment spreads. See 

AR 14. Without a clear explanation, it was reasonable for the Corps to assess a significant 

weakness to Thalle’s proposal because Thalle’s proposed means and methods for completing the 

project did not provide the Corps with confidence in its ability to successfully complete the 

project on schedule. See AR 16.

6 The government explains that the Corps “made a typographical error here, using 346 instead of 376.” Def.’s Reply 

at 13 n.4, ECF No. 28. This apparent administrative error is not pertinent to Thalle’s challenge.

7 The Court denotes that “*” stands for multiplication. 
9

3. The Corps’ assessment of a significant weakness because Thalle’s 

proposal failed to discuss applying for and obtaining the necessary permits

was not arbitrary or capricious. 

The Corps assessed a significant weakness to Thalle’s proposal because “[Thalle]

discusses following NPDES & FDEP permits . . . however [it] does not discuss applying for or 

obtaining the necessary permits.” 8 AR 2164. The Solicitation required offerors to “[p]rovide a 

detailed description of the proposed plan to manage surface and groundwater within the limits of 

construction.” AR 15. Under the permits portion of the Solicitation, offerors were specifically 

required to “[o]btain NPDES Stormwater Construction Generic Permit to provide coverage 

under [NPDES].” AR 733. Thalle argues that the assessment of this significant weakness was 

arbitrary because the Corps unequally treated its proposal and employed unstated evaluation 

criteria. Pl.’s Mem. at 22-23, 28. 

Thalle argues that the Corps treated its proposal unequally because P&J was assessed a 

significant strength and Thalle was assessed a significant weakness for what amounts to the same 

proposal content regarding permits. Pl.’s Mem. at 22-23. The Corps assessed a significant 

strength to P&J’s proposal because it stated that P&J would apply for the necessary permit upon 

Notice to Proceed (“NTP”). AR 1067 (“Upon NTP, P&J plans on immediately applying for a 

water use individual permit to deal with large rain events and dewatering efforts.”); AR 2155. On 

the other hand, Thalle’s proposal received a significant weakness because it stated only that it 

would comply with the approved permits. See AR 1305 (“During construction, Thalle will 

follow the approved NPDES and FDEP permits to ensure compliance, as well as be active in 

monitoring site conditions daily to maintain production goal.”); AR 2164. Thalle argues that its 

proposed permitting approach is substantively indistinguishable from P&J’s proposed approach.

See Pl.’s Mem. at 22-23.

However, a comparison of Thalle’s and P&J’s respective proposals does not show 

unequal treatment by the Corps. As part of its approach for managing surface and groundwater, 

P&J’s proposal explicitly addressed the need to acquire “a water use individual permit to deal 

with large rain events and dewatering efforts.” AR 1067. Further, P&J’s proposal stated that it 

would apply for the necessary permit immediately “upon notice that P&J is the successful 

proposer.” AR 1048 (“We will proceed with this work at our own risk until a formal NTP is 

received.”). P&J explained that it has “used this proactive approach in other successful projects 

enabling us to start preparations early.” Id. P&J’s more detailed description of when it will 

obtain the permits is distinguishable from Thalle’s proposal, which merely stated that it would 

comply with the permits and did not clearly acknowledge the need to apply for permits or state 

when Thalle would undertake such an application process. See Intuitive Rsch. & Tech. Corp. v. 

United States, 157 Fed. Cl. 1, 7 (2021). Based on these differences, the Corps acted reasonably

when it assessed a significant weakness to Thalle’s proposal and a significant strength to P&J’s 

proposal.

8

“NPDES” is short for the National Pollution Discharge Elimination System. See AR 732. The NPDES “is designed 

to prevent harmful discharges into the Nation’s waters” and generally “requires dischargers to obtain permits that 

place limits on the type and quantity of pollutants that can be released into the Nation’s waters.” Chesapeake Bay 

Found., Inc. v. Severstal Sparrows Point, LLC, 794 F. Supp. 2d 602, 608 (D. Md. 2011) (internal citations & 

quotations omitted). “FDEP” refers to the Florida Department of Environmental Protection.
10

Additionally, the Corps did not employ unstated evaluation criteria when it assessed a significant 

weakness to Thalle’s proposal for its failure to include a “specific narrative describing the 

application for the[] permits.” Pl.’s Mem. at 28. The Solicitation specifically required that 

offerors provide a detailed description of their plan to manage surface and groundwater. AR 15. 

An explanation of how and when the necessary permits would be applied for and obtained is 

intrinsic in the Solicitation requirement to provide a detailed description of the proposed plan for 

managing surface and groundwater. See Banknote Corp., 56 Fed. Cl. at 387 (“[I]t is well-settled 

that a solicitation need not identify each element to be considered by the agency during the 

course of the evaluation where such element is intrinsic to the stated factors.”) (quotations 

omitted). The Corps determined the lack of detail regarding permitting requirements in Thalle’s 

proposal created increased risk to contract performance. See AR 2164-65. The Corps did not use 

a significantly different basis for evaluating Thalle’s proposal than what was stated in the 

Solicitation. Based on the record, Thalle’s unstated evaluation criteria argument amounts to a 

mere disagreement with the Corps’ proposal evaluation results. See Avtel Servs., Inc. v. United 

States, 70 Fed. Cl. 173, 218 (2006) (“[A] protestor’s mere disagreement with the agency’s 

evaluation determination does not provide a basis for sustaining the protest.”) (quotations 

omitted). 

4. The Corps’ assessment of two significant weaknesses because Thalle’s 

proposal included establishment of an on-site laboratory and did not 

account for the on-site laboratory in its construction schedule was arbitrary 

and capricious. 

Thalle’s proposal was assessed two significant weaknesses stemming from its proposed 

use of an on-site laboratory. See AR 2165-66. The Solicitation required that an offeror’s 

proposed Technical Approach Plan “[p]rovide a detailed explanation of how the offeror will 

ensure quality control, including a description of proposed quality control measures.” AR 15. 

The Solicitation permitted offerors “to procure the services of a Corps of Engineers’ approved 

testing laboratory or establish an approved testing laboratory at the project site.” AR 702. The 

purpose of the laboratory is to “perform specified or required tests to verify that control measures 

are adequate.” Id. An on-site laboratory must meet certain inspection validation requirements. 

See AR 702-03. Additionally, an offeror cannot begin work that requires testing until the 

offeror’s on-site lab has been “inspected, Corps validated[,] and approved by the Contracting 

Officer.” AR 791.

In its evaluation of Thalle’s proposal, the Corps acknowledged that “[t]he contract allows 

an option to utilize an off-site laboratory or establish an on-site laboratory” but then assessed a 

significant weakness for Thalle’s proposed use of an on-site laboratory because “[t]he laboratory 

testing required for the project does not readily justify such efforts and no explanation as to why 

the offeror’s would risk schedule and expend additional resources and time to warrant 

establishment of an on-site laboratory is present within the proposal.” AR 2165. The Corps 

assessed a related weakness because Thalle’s construction schedule “does not consider the 

establishment of an on-site . . . laboratory.” AR 2165. Thalle argues that the Corps’ assessment 

of these significant weaknesses constituted unequal treatment because the Corps did not assess 

similar weaknesses to P&J’s proposed use of an on-site laboratory. Pl.’s Mem. at 21-22.

Thalle’s proposal stated that a “qualified testing firm will be selected to install and 

maintain the contractor’s on-site testing laboratory, ACI Certified Lab Testing and ACI Certified 

Field-Testing Technicians.” AR 1310. P&J’s proposal stated that a “USACE Validated 

Construction materials testing lab will be used on-site, during construction for materials testing 

services as required in the contract documents.” AR 1069-70. The government argues that 

“[P&J’s] laboratory plan is distinguishable from Thalle’s because [P&J] will use a pre-approved

lab while Thalle will ‘install’ a new lab that will require validation.” Def.’s Reply at 2 (emphasis 

in original). However, the government’s argument is not supported by the contents of P&J’s 

proposal. Nowhere in P&J’s proposal does it state that the on-site laboratory proposed by P&J is 

pre-validated. It’s proposal simply states that it will use a “Validated Construction materials 

testing laboratory.” See AR 1069. Based on this record, P&J’s proposed onsite laboratory will 

need to be installed onsite and validated by the Corps in accordance with the validation 

requirements set forth in the Solicitation. See AR 791. This is not substantively distinguishable 

from Thalle’s proposed installation and maintenance of an onsite laboratory, which will be 

subject to the same validation requirements contained in the Solicitation. Therefore, the Corps 

treated Thalle’s proposal unequally when it assessed a significant weakness against Thalle’s 

proposal and did not assess the same weakness to P&J’s proposal. If the Corps determined that 

establishment of an on-site laboratory was unwarranted for this project, resulted in unnecessary 

schedule risk, and thus warranted assessment of a significant weakness, the Corps should have 

applied this determination equally to both Thalle’s and P&J’s respective proposals.9

The Court also finds that the Corps unequally treated Thalle’s proposal when it assessed a 

significant weakness to Thalle’s proposal because its “schedule does not consider the 

establishment of an on-site [Quality Control] and [Quality Assurance] laboratory.” AR 2165. The 

Solicitation required that “[a]ll work items listed in the Technical Approach Plan should be 

included in the Construction Schedule and the timeframes given for work items in the 

Construction Schedule.” AR 16. It also stated that any conflicts between the technical approach 

and construction schedule may be noted as a weakness. Id. The issue here, however, is that 

neither Thalle’s, nor P&J’s, construction schedules list the establishment of an on-site laboratory, 

so both technical approaches contain inconsistencies with the respective construction schedules. 

See AR 1076-93, 1321. P&J argues that set up of an on-site lab was “accounted for in P&J’s 

schedule in . . . Contractor Quality Control (CQC) plan, Environmental Protection Plan, and 

Mobilize & Set up Office Trailers.” Def.-Intervenor’s Mot. for J. on the Admin. R. at 27 (citing 

AR 1076, 1078)., ECF No. 25 However, the record does not support P&J’s assertion. P&J’s 

schedule does not contain a line item for establishment of an on-site laboratory, nor does it make 

clear that the broader schedule line items for quality control include the necessary time for 

establishment of the on-site laboratory. See generally AR 1076-93. Based on the record before 

the Corps, the Court does not find a rational basis for the Corps’ assessment of a significant 

9 Thalle also argues that the Corps employed unstated evaluation criteria because “[n]othing in the [S]olicitation 

required, or even suggested, that Thalle needed to justify its use of an on-site lab” or “to justify the schedule and cost 

components of using an on-site lab[.]” Pl.’s Mem. at 27; Pl.’s Reply at 7, ECF No. 26. The Court does not address 

this argument because the Court finds that the Corps’ assessment of a significant weakness for Thalle’s proposed use 

of an on-site laboratory was based on unequal treatment.

weakness to Thalle’s proposal for this schedule deficiency without a corresponding significant 

weakness to P&J’s proposal.10 

5. The Corps’ assessment of a weakness because Thalle’s proposal contained 

larger muck estimates than expected under the Solicitation was not

arbitrary or capricious.

The Corps assessed a weakness to Thalle’s proposal because it “estimates muck to be 

4830 CY per acre, which equates to a 3 ft thick layer of muck, which is thicker than the 

expectation set by the contract (0.6” to 2 ft thick) and provides no basis for the assumption 

within the proposal (i.e., local experience).” AR 2165. The Solicitation requires that offerors 

“[p]rovide typical production rates for all listed equipment planned to be utilized to . . . excavate 

. . . material.” AR 15. Thalle states in its proposal that “[b]y utilizing a combination of two D8 

dozers and two 14 blades to push and [withdraw] the material, and two 349 excavator[s] to load 

40 ton haul trucks on each canal, Thalle expects to maintain 530 CY per hour during demucking 

and grubbing operations” and “[w]ith an estimated 360 Acres to clear and demuck, this is an 

average of 4,838 CY per AC.” AR 1297. The Corps determined that Thalle’s planned production 

rates exceeded the expected muck thickness and that the lack of an explanation relating planned 

production rates to expected project conditions demonstrated that Thalle was unfamiliar with the 

project specifications. See AR 2165.

Thalle challenges this weakness as arbitrary stating that “[w]hether the volume of muck 

is greater than what the Corps estimated . . . [has] no impact on Thalle’s schedule, cost to the 

government, or risk of performance, since Thalle is prepared to move significantly more muck 

than set forth in the Solicitation.” Pl.’s Mem. at 24. Thalle also alleges unequal treatment 

because the Corps assessed P&J’s proposal with a strength on the basis that P&J “anticipates and 

has a plan for dealing with deeper muck & marl pockets that are not obvious on boring logs 

present within the Geotechnical Data Report.” Pl.’s Mem. at 24-25; AR 2156. 

The Court finds that the Corps had a reasonable basis to question Thalle’s understanding 

of the project conditions and assess a weakness to Thalle’s proposal due to its lack of detail. See

AR 14 (“Clear identification of proposal details shall be the sole responsibility of the offeror[.]”); 

see also Harmonia Holdings Grp., LLC v. United States, 152 Fed. Cl. 97, 107 (2021) (finding a 

weakness for a contractor emphasizing work that is not important to the solicitated project could 

present a risk because it can show the contractor does not understand the work). Thalle’s 

proposal for excavating and handling muck is distinguishable from P&J’s proposal. AR 2156. 

P&J’s proposal explicitly addresses the expected project conditions by stating that “[m]uck 

thickness for most of the project varies between 6 to 18 inches across the site” and “[d]eeper 

pockets of muck of up to 4 feet in thickness have been identified.” AR 1052. P&J’s proposal 

further explains that “[o]n similar projects, P&J has encountered various depressions and voids 

10 The Corps assessed a weakness to Thalle’s proposal for its “over-simplified” schedule and did not assess a 

corresponding weakness to P&J’s proposal. See AR 2166. For the reasons discussed below, the Court determined 

that this was reasonable because P&J’s schedule is significantly more detailed than Thalle’s schedule. Compare AR 

1076-93 (P&J’s Schedule) with AR 1321 (Thalle’s Schedule). However, this does not affect the Court’s conclusion 

with respect to how the Corps treated the offerors’ respective schedules with regarding the use of an on-site 

laboratory. 
13

within the cap rock where excessive muck and marl collects. These pits can prove to be difficult, 

however our experience has prepared our crews to efficiently mitigate these deposits with the 

following approach.” AR 1052. This level of detail does not appear in Thalle’s proposal. See AR 

1297. Therefore, while the Corps assessed a weakness to Thalle’s proposal for its lack of detail 

around its planned production rates, the Corps assessed a strength to P&J’s proposal because of 

P&J’s detailed plan. See AR 1051-52 (P&J’s proposed muck handling plan). Thus, the Corps did 

not unequally treat Thalle’s proposal, and it had a reasonable basis to conclude that P&J’s more 

detailed plan for excavating and handling muck “[i]nstills confidence that the offeror has a clear 

understanding of the site conditions and reduces the projects risk to differing site condition 

(DSC) claims.” AR 2156; see Office Design Grp., 951 F.3d at 1372-73. 

6. The Corps’ assessment of a weakness for Thalle’s failure to provide 

sufficient detail on how it would overcome potential obstacles was

arbitrary and capricious.

The Corps assessed a weakness to Thalle’s proposal because the potential obstacles to 

construction that Thalle listed in its proposal did “not provide sufficient detail to instill 

confidence” in Thalle’s ability “to overcome the obstacles in the anticipated construction 

environment.” AR 2165. The Solicitation required that offerors “[i]dentify possible obstacles to 

construction operations and how the offeror will overcome these obstacles.” AR 15. Thalle 

identified two obstacles: “Extreme or Unusual Adverse Weather” and “Environmental 

obstacles.” AR 1312. Thalle also proposed plans to overcome these identified obstacles. See id.

In its evaluation, the Corps acknowledged the two obstacles identified by Thalle but determined 

that Thalle’s proposal was lacking sufficient detail on its ability “to overcome the obstacles in 

the anticipated construction environment.” AR 2165. Thalle challenges this weakness arguing 

that it is based on unstated evaluation criteria because “the Solicitation did not require offerors to 

identify any specific potential obstacles to construction.” Pl.’s Mem. at 30. 

The Court finds that, while the Corps did not employ unstated evaluation criteria, its 

evaluation does not contain a rational basis for its assessment of a weakness to Thalle’s proposal. 

The Corps assessed Thalle’s proposal against the explicit Solicitation requirement to identify 

obstacles and provide a mitigation plan and therefore did not apply a significantly different basis 

in evaluating Thalle’s proposal than was disclosed in the Solicitation. However, the Corps’

evaluation provides no basis for the assessment of a weakness aside from the conclusory

statement that Thalle’s list of potential obstacles “does not instill confidence” in Thalle’s ability 

to overcome the “obstacles in the anticipated construction environment.” AR 2165. This merely 

restates the evaluation method set forth in the Solicitation without any explanation regarding the 

basis for the weakness. AR 14. For instance, it is unclear from the Corps’ evaluation whether the 

Corps assessed the weakness because Thalle’s mitigation plans for the identified obstacles lacked 

detail or because Thalle failed to identify other potential obstacles in the anticipated construction 

environment. Accordingly, the Corps has not provided a satisfactory explanation for assessing 

this weakness. See State Farm, 463 U.S. at 43 (“[T]he agency must examine the relevant data 

and articulate a satisfactory explanation for its action including a rational connection between the 

facts found and the choice made.”) (quotations omitted).
14

7. The Corps’ assessment of a weakness because Thalle’s “staggered 

approach” was arbitrary and capricious. 

Thalle’s proposal was assessed a weakness because the Corps determined that it

“contains conflicting information” in the proposed schedule narrative and construction schedule.

AR 2165. According to the Corps, the “Construction Schedule Activity Timeframe narrative 

states using a staggered approach to the Seepage and I/O Canals for Blasting and excavation, 

[and] the schedule has them starting at the same time[.]” AR 2165. Thalle argues that the Corps 

arbitrarily assessed this weakness because its proposal does not contain conflicting information, 

and the Corps “failed to give Thalle credit for information in its proposal that clearly met the 

requirements[.]” Pl.’s Mem. at 31.

The Solicitation required that offerors “[p]rovide [the] basis for timeframes for required 

work items proposed in . . . [the] Construction Schedule, including all assumed contingencies 

(i.e. adverse weather, mechanical shut-down, environmental issues, additional permits[,] etc.).” 

AR 15. The Solicitation also stated that “[a]ny conflicts between Element 1 [Technical Approach 

Plan] and Element 2 [Construction Schedule] may be noted as a weakness.” AR 16.

Contrary to the Corps’ explanation, the Court finds that the narrative in Thalle’s technical 

approach plan does not conflict with its proposed construction schedule. Thalle’s construction 

schedule narrative clearly states that “[b]lasting and excavation will run concurrent with both 

canals.” AR 1313 (emphasis added). This is also reflected in Thalle’s construction schedule, 

which shows that blasting and excavation start and stop on the same day for each canal. See AR 

1321. For both the I/O canal and seepage canal, Thalle explained in its narrative that “blasting is 

expected to take 150 days to complete, while the excavation and haul will take 380 days.” Id. 

Thalle further explained for both canals that by “[u]sing a staggered approach, a total of 400 days 

is expected.” Id. The reference to “staggered approach” clearly refers to the staggering of 

blasting and hauling on each canal, rather than between canals. The Corps’ evaluation ignores 

that Thalle’s proposal calls for concurrent blasting and excavating of the I/O and seepage canals 

and that this concurrent activity is also consistent with Thalle’s proposed construction schedule. 

Therefore, the Corps assessment of a weakness because of conflicting information in Thalle’s 

proposal is not supported by the record. See Ala. Aircraft Indus., 586 F.3d at 1375 (highlighting 

an agency’s action is arbitrary and capricious when the agency “offer[s] an explanation for its 

decision that runs counter to the evidence before the agency”) (quotation marks omitted) 

(quoting State Farm, 463 U.S. at 43). 

8. The Corps’ assessment of a weakness for the lack of detail in Thalle’s 

construction schedule was not arbitrary or capricious.

Thalle received a weakness because the Corps determined that its proposed construction

schedule was “oversimplified and lack[ed] appropriate detail to track milestones.” AR 2166. The 

Solicitation requires that offerors provide a schedule of construction “showing the start and 

completion dates, interdependence, and other relative scheduling factors for all of the items of 

work listed in the [Technical Approach Plan].” AR 16. The Solicitation lists twelve activities that 

the schedule must contain. Id. Thalle argues that the Corps applied unstated evaluation criteria 
15

because “the [S]olicitation required only that a proposed schedule show[] the start and finish 

dates and schedule logic” for the minimum schedule requirements contained in the Solicitation. 

Pl.’s Mem. at 27; AR 16. Thalle argues that it met this requirement and, therefore, should not 

have been assessed a weakness. Pl.’s Mem. at 28. 

The Court is not persuaded by Thalle’s argument that the Corps employed unstated 

evaluation criteria in assessing this weakness. The Corps assessed a weakness because Thalle’s 

schedule, while otherwise meeting the minimum schedule requirements, lacked sufficient detail 

for the Corps to track milestones. AR 2166. The Solicitation stated that the evaluation method 

for the construction schedule would assess “the degree to which the offeror’s proposal meets the 

requirements of the Solicitation as well as the feasibility of the proposed approach.” AR 16. It 

further explained that the list of activities was provided as an example and “is not the only 

corroboration that will be made between the Technical Approach Plan and Construction 

Schedule.” Id. Accordingly, a construction schedule that meets or moderately exceeds the 

example requirements does not preclude the assignment of a weakness, and the Corps may 

reasonably determine the degree to which the proposed schedule supports the feasibility of the 

proposed approach. See Lockheed Missiles & Space Co., Inc. v. Bentsen, 4 F.3d 955, 959 (Fed. 

Cir. 1993) (“[A]gencies are entrusted with a good deal of discretion in determining which bid is 

the most advantageous to the [g]overnment.”) (quotations omitted). The offeror “carries the 

burden of presenting an adequately written proposal, and an offeror's mere disagreement with the 

agency's judgment concerning the adequacy of the proposal is not sufficient to establish that the 

agency acted unreasonably.” Westech Int’l., Inc. v. United States, 79 Fed. Cl. 272, 296 (2007) 

(quotations omitted). Thalle’s proposed schedule consisted of one page, and based on the Corps 

evaluation, its level of detail did not allow the Corps to track the milestones. AR 1321. The Court 

cannot fault the Corps for assessing a weakness to Thalle’s construction schedule based on the 

Solicitation requirements and evaluation method. 

9. The Corps’ assessment of a weakness because Thalle included only one 

crusher, screener, and loader in its planned equipment was not arbitrary or 

capricious. 

The Corps assessed a weakness to Thalle’s and P&J’s respective proposals because each 

“proposed only [a] single crusher, screener, and loader as planned equipment.” AR 2165, 2156. 

Thalle argues that “the Corps offset the weakness in P&J’s proposal . . . because elsewhere P&J 

indicated that it would use more than one crusher” and “the Corps did not afford Thalle the same 

attention even though Thalle’s proposal also explained it would use a second crusher.” Pl.’s 

Reply at 14.

The Court is not persuaded by Thalle’s argument. Both Thalle’s and P&J’s proposed 

equipment lists include only one crusher, screener, and loader. See AR 1045-46, 1296-97. The 

Corps viewed this as a risk and thus assessed a weakness to both Thalle’s and P&J’s proposals. 

AR 2156, 2165. Though both offeror’s equipment lists included only one crusher, both proposals 

contained references to the potential use of more than one crusher. See AR 1064 (P&J states that 

it “would anticipate using two more of these mobile crushers for this project.”); AR 1299 (Thalle 

states that “a second crusher will be utilized depending on availability.”). On this basis, the 

Corps assessed a strength to P&J’s proposal because P&J “noted the use of multiple mobile
16

crushers for this project, though only one was included in the list of equipment.” AR 2156. The 

Corps also separately assessed a strength to Thalle’s proposal on the basis that it “noted it would 

. . . bring additional equipment to the project to maintain production.” AR 2164. The Court finds 

that Thalle and P&J were not treated unequally because both offerors received the same 

treatment for the same weakness, both proposals contained a similar inconsistency, and both 

received a similar corresponding strength that arguably offset the respective weakness. 

10. The Corps’ assessment of a weakness because Thalle’s proposal failed to 

address the need to shift resources between canals was not arbitrary or 

capricious. 

The Corps assessed a weakness to Thalle’s proposal because Thalle “does not 

acknowledge the need to shift resources between canals due to their disproportional quantity of 

excavation per 530 [linear foot (“LF”)].” AR 2165. Thalle argues that this weakness was 

arbitrary because the Solicitation did not include a requirement to shift resources between canals

and that its “proposal clearly explained how it would maintain an excavation rate of 530 [Linear 

Feet] per week on each canal” and “did not require the shifting [of] resources between canals” to 

complete the project on schedule. Pl.’s Mem. at 30. 

The Court is not persuaded by Thalle’s argument. The Solicitation requires that offerors 

provide production rates for equipment planned to be utilized to excavate the canals. AR 15. The 

evaluation method assesses the degree to which the offeror’s proposal meets the Solicitation 

requirements, as well as the feasibility of the proposed approach. AR 16. The feasibility of the 

proposed approach will measure how well the proposed means and methods provide the 

government with confidence of successful project completion within the contract schedule. Id. 

Thalle’s proposed approach involves blasting and excavating both canals concurrently 

using two equipment spreads per canal. AR 1297, 1313. The construction drawings contained in 

the Solicitation provide that the canals have differing quantities of material requiring excavation. 

AR 980-82. Based on Thalle’s proposed concurrent approach and the differing requirements 

between canals, it was reasonable for the Corps to conclude that Thalle may need to shift 

resources between canals to complete the project on schedule since the canal with the greater 

quantity of material may require more resources than the canal with lesser material. Because 

Thalle’s proposal failed to address this apparent risk in its approach, the Corps had a rational 

basis for assessing a weakness because the method for blasting and excavating the canals 

described in Thalle’s proposal did not provide the Corps with confidence that Thalle would 

successfully complete the project in a timely manner. See AR 16. 

11. The Corps’ assessment of a weakness because Thalle’s proposed daily 

production rate was unclear was not arbitrary or capricious.

The Corps also assessed a weakness against Thalle’s proposal because Thalle’s planned 

production rate “assumes anticipated hourly production can be maintained for 10 hours a day.” 

AR 2165. The planned production rate in Thalle’s proposal provided “1,128 CY per hour, or 

11,280 CY per shift.” AR 1297. Thalle’s proposal then explained that “[t]his production rate 

provides for enough float in the schedule to account for downtime, weather, equipment
17

maintenance, or environmental stoppages but not exceed the 530 feet per week allowed.” Id. The 

Corps derived the “10 hours a day” by dividing Thalle’s proposed “per shift” production rate of 

11,280 CY by its proposed “per hour” rate of 1,128 CY. See AR 1297, 2165. The Corps

apparently viewed this production rate as a weakness because it does not account for inevitable 

downtime. Thalle challenges this conclusion by the Corps as arbitrary because it alleges that the 

Corps “ignore[ed] clearly presented information.” Pl.’s Mem. at 29. In its briefing, Thalle 

explains that it accounted for downtime because “[a]s with the hourly production rate, this 

represented only 75% productivity to account for the inevitable delays that accompany every 

construction project.” Id. at 30. Thalle further elaborates that “[i]f Thalle had proposed 10 hours 

of full productivity per day, it would have proposed to haul 15,040 CY per day.” Id.

For the same reason discussed above with respect to Thalle’s proposed equipment 

spreads, see supra Section III.A.2, the Court finds that Thalle’s proposed daily production rate is 

not clear, and the Corps was reasonable to assess this weakness. Thalle does not indicate

anywhere in its proposal that its planned production rates represent only 75% of its maximum 

production rate. Without this necessary clarifying information, it was not unreasonable for the 

Corps to interpret Thalle’s proposal as proposing its maximum production rate and conclude that 

such rate did not provide enough float in the schedule to account for downtime. See AR 14 (“The 

[g]overnment will not make assumptions concerning intent [and] capabilities . . .”); see also 

Structural Assocs., Inc./Comfort Sys. USA (Syracuse) Joint Venture v. United States, 89 Fed. Cl. 

735, 744 (2009) (“An offeror has the responsibility to submit a well-written proposal with 

adequately detailed information that allows for a meaningful review by the procuring agency.”)

(quoting CACI Techs., Inc., B-296946, 2005 CPD ¶ 198 at 5 (Comp. Gen. Oct. 27, 2005)).

12. The Corps’ failure to assess a strength to Thalle’s proposal for its use of 

GPS was arbitrary and capricious. 

Thalle argues that the Corps unequally treated its proposal by assigning three strengths to 

P&J’s proposal for proposal elements that Thalle alleges are substantively indistinguishable from 

its proposal. Pl.’s Mem. at 23-24, 26. First, P&J’s proposal was assessed a strength because it 

“provided significant detail along with means and methods for the blast plan sequence” which

“included graphics of the blast pattern along with estimated weight of explosives needed per 

drilled hole.” AR 2156. Thalle claims that its proposed blasting plan “included information and 

graphics nearly identical [to] those the Corps praised in P&J’s proposal” and thus Thalle should 

have likewise been assessed a strength. Pl.’s Mem. at 23. While the government concedes that 

Thalle’s blasting diagram, AR 1302-04, is “very similar” to P&J’s blasting plan, AR 1108-10, 

the government argues that the similarities end there. Def.’s Mot. for J. on the Admin. R. at 12, 

ECF No. 24. The government explains that P&J’s blasting plan provides more detail, including 

the type of explosive, detonation device, monitoring equipment, and procedures for inclement 

weather. Id.; AR 1065-66; see also AR 1056-57, 1059-60. The Court agrees with the government

that Thalle’s and P&J’s proposed blasting plans are not substantively indistinguishable. Thalle’s 

plan consists of only a single page, and, while it may contain identical features to P&J’s plan, it

lacks the same level of detail. The Corps was not arbitrary in crediting P&J’s plan with a strength 

for its overall more detailed plan and electing to not assign a strength to Thalle’s plan. See Office 

Design, 951 F.3d at 1372-73; Intuitive Rsch., 157 Fed. Cl. at 7.
18

Second, the Corps assessed a strength to P&J’s proposal because P&J “maintains an inhouse equipment service center in Florida (~200 mi from project site).” AR 2155. Thalle argues 

unequal treatment on the grounds that it “proposed to staff mechanics and lube men on-site[] yet 

received no recognition from the Corps.” Pl.’s Mem. at 26; AR 1296 (Thalle’s proposal stating 

that “Thalle owns and operates a large fleet of equipment with the necessary support staff of 

mechanics and lube men to keep equipment moving throughout the project.”). These proposal 

features, however, are not substantively indistinguishable. An in-house equipment service center, 

even if located away from the project site, is not the same as a staff of mechanics and lube men. 

Therefore, the Corps rationally assessed a strength to P&J’s proposal for its maintenance facility

while not similarly recognizing Thalle’s maintenance support staff. See Office Design, 951 F.3d 

at 1372-73; Alpine Companies, Inc. v. Untied States, 156 Fed. Cl. 681, 689-90 (2021); Vantage 

Assocs., Inc. v. United States, 59 Fed. Cl. 1, 19 (2003) (“The wide discretion afforded 

contracting officers extends to a broad range of procurement functions, including the 

determination of what constitutes an advantage over those proposals.”).

Third, the Corps assessed a strength to P&J’s proposal because P&J “indicates that all 

equipment will use GPS for excavation in the wet to ensure templates are met and within 

tolerance.” AR 2156. Thalle claims that its proposal also indicates use of “GPS-enabled

equipment, but the Corps ignored the benefit.” Pl.’s Mem. at 26. The Court agrees with Thalle

that the Corps unequally treated Thalle’s proposal when it assigned a strength to P&J for the use 

of GPS for excavation and did not assign a strength to Thalle for its proposed use of GPS. P&J’s 

proposal references the use of GPS in multiple places, but these references are largely redundant 

and boil down to P&J using GPS for excavation. See, e.g., AR 1057 (“A large hydraulic 

excavator equipped with GPS will begin excavation” and “a smaller excavator(s) also equipped 

with GPS”); AR 1060 (same quote); AR 1058 (“The use of GPS is essential, as this excavation 

will be done in the wet.”); AR 1060 (same quote); AR 1072 (“Utilize GPS on excavators digging 

canals”). Thalle’s proposal also references the use of GPS for excavation. AR 1311 (stating that 

all work will be monitored using “GPS controls built into the earthmoving machines.”). While 

the references to GPS are different in quantity and utilize different terminology, the proposed use 

of GPS for excavation purposes to ensure quality control and compliance with contract 

requirements is substantively indistinguishable. Accordingly, if the Corps viewed the use of GPS

as a strength, it should have assessed a strength to Thalle’s proposal similar to that assessed to 

P&J’s proposal.

B. The Corps was not required to engage in clarifications or discussions.

Thalle argues that the Corps was required to engage in clarifications and discussions to 

allow Thalle to fix the defects in its proposal. See Pl.’s Mem. at 32-34; Pl.’s Reply at 21-22. 

Clarifications are “limited exchanges” that the government may use to allow offerors “the 

opportunity to clarify certain aspects of their proposals . . . or to resolve minor or clerical 

errors.” FAR 15.306(a) (1-2). Clarifications may not be used to “cure proposal deficiencies or 

material omissions, materially alter the technical or cost elements of the proposal, or otherwise 

revise the proposal.” Dell Fed. Sys., L.P. v. United States, 906 F.3d 982, 998 (Fed. Cir. 2018). 

The Contracting Officer has the discretion to decide whether to seek clarifications. Safeguard 

Base Operations, 989 F.3d at 1346. A contracting officer abuses that discretion if they “should 

have discerned that the protester made an error rather than a deliberate decision.” Criterion Sys., 
19

Inc. v. United States, 140 Fed. Cl. 29, 37 (2018) (articulating that “the obviousness of the error is 

an important aspect of determining whether the [agency] acted reasonably by not seeking 

clarification”). Different from clarifications, discussions “are exchanges . . . between the 

[g]overnment and offerors, that are undertaken with the intent of allowing the offeror to revise its 

proposal.” FAR 15.306(d). The decision to engage in discussions is also within the contracting 

officer’s discretion. Chenega Healthcare Servs., LLC v. United States, 138 Fed Cl. 644, 654 

(2018); see also Allied Tech. Grp., Inc. v. United States, 649 F.3d 1320, 1327-28 (Fed. Cir. 

2011). 

Thalle argues that the Corps was required to seek clarifications before assessing a 

significant weakness because of its inclusion of the commitment letters for two separate blasting 

subcontractors. Pl.’s Mem. at 33-34. The Court disagrees because Thalle’s inclusion of two 

blasting subcontractors in its proposal is not an obvious clerical error that would require the 

Corps to seek clarifications. Thalle submitted letters of commitment for both Florida Energy and 

CD&B, which caused confusion on which subcontractor would perform the blasting work. AR 

1288-90, 2165. This confusion was exacerbated because Thalle mentioned only Florida Energy

in its proposed blasting plan yet it utilizes only CD&B to demonstrate its blasting experience.

See AR 1301, 1349-57. This lack of clarity with respect to its blasting subcontractors appears to 

result from a deliberate decision to use different blasting subcontractors to satisfy different

proposal requirements, as opposed to a clerical error. Accordingly, the Corps did not act 

arbitrarily when it did not seek clarifications from Thalle. Criterion Sys., 140 Fed. Cl. at 37.

Thalle also argues that clarifications were required with respect to the weaknesses 

assigned by the Corps for Thalle’s proposed equipment spreads and daily production rate. Pl.’s 

Mem. at 33-34. The Court disagrees because the weaknesses assessed against these two areas of 

Thalle’s proposal do not arise from obvious clerical errors and instead are based on a lack of 

clarity in Thalle’s proposed technical approach. Further, the record supports that the Corps 

would have needed new information regarding Thalle’s proposed approach to effectively remedy 

the lack of clarity. For instance, in order to remedy the lack of clarity around Thalle’s proposed 

equipment spreads, Thalle would need to insert the rationale that it offers in its briefing, that 

“1,128 CY per hour rate was 75% of this rate to account for inefficiencies, downtime, and other 

nonproductive time.” Pl.’s Mem. at 29-30. Similarly, Thalle would need to explain that its 

proposed daily production rate of 11,280 CY per shift is 75% of the maximum rate. Pl.’s Mem. 

at 30. Clarifications are not to be used for supplementing a proposed technical approach with 

new information. See PAE Aviation & Tech. Servs., LLC v. United States, 156 Fed. Cl. 454, 465 

(2021). Accordingly, the Corps did not act arbitrarily when it did not seek clarifications from

Thalle about its proposed equipment spreads and daily production rate. See Dell Fed., 906 F.3d 

at 998; see also Criterion Sys., 140 Fed. Cl. at 37.

With respect to discussions, the Corps did not act arbitrarily or abuse its discretion by not

conducting discussions. The contracting officer has discretion not to open discussions when the 

solicitation provides notice to offerors that the government intends to award without discussions. 

See Chenega, 138 Fed. Cl. at 654 (“[T]he overwhelming weight of authority indicates that a 

contracting officer's discretion to not open discussions generally trumps a protestor's argument 

that the agency should have opened discussions to rehabilitate unsatisfactory proposals before 

making a best value contract award.”); Allied Tech. Grp., 649 F.3d at 1327-28; see also FAR 
20

15.306(a)(3) (“Award may be made without discussions if the [S]olicitation states that the 

[g]overnment intends to evaluate proposals and make award without discussions.”). In this case, 

the Solicitation notified offerors that “[t]he [g]overnment intends to evaluate proposals and 

award a contract without discussions” so “the offeror’s initial proposal should contain the 

offeror’s best terms from a price and technical standpoint.” AR 14 (emphasis added).

Despite the well-established discretion afforded to contracting officers to determine 

whether to open discussions, Thalle, citing DynCorp Int’l LLC v. United States, 76 Fed. Cl. 528, 

540 (2007), argues that an agency’s decision to not engage in discussions is only reasonable after

“an affirmative determination that discussions could not improve the protestor’s proposal enough 

to make its proposal competitive.” Pl.’s Reply at 21. Thalle claims that the Corps decision to not 

engage in discussions was unreasonable because the Corps did not affirmatively state in its 

Source Selection Decision that discussions would not improve Thalle’s proposal enough to make 

it awardable. See Pl.’s Reply at 21–22. This understanding of DynCorp is misplaced. Indeed, the

court in DynCorp acknowledged an affirmative determination by the agency that discussions 

were unlikely to change the best value determination. However, the court’s decision was based 

on deference afforded to the agency’s discretionary determination to not conduct discussions. 

See DynCorp, 76 Fed. Cl. at 540 (“The court defers to the Air Force’s discretion whether or not 

to hold discussions [thus] . . . [t]he Air Force’s decision not to hold discussions, even here where 

only two proposals were received, was within the discretion afforded a procuring agency.”). The 

Court is unaware of any binding precedent, and Thalle has not provided any, that requires an 

agency to make an affirmative determination that discussions would not improve a deficient 

proposal enough to make such proposal eligible for consideration for award, especially when, as 

in the present case, the agency informed the offerors in the solicitation of its intention to make an 

award without discussions. Accordingly, the Court defers to the Corps’ discretion to not open 

discussions in this case. 

C. Thalle was prejudiced by the Corps’ arbitrary and capricious evaluation of 

its proposal.

Having found that the Corps acted arbitrarily and capriciously, the Court now considers 

whether Thalle was prejudiced by the Corps’ errors. See Bannum, 404 F.3d at 1351 (stating that 

once a court finds that an agency acted arbitrarily, the court “proceeds to determine, as a factual 

matter, if the bid protester was prejudiced by that conduct”). For Thalle to prevail, it “must show 

prejudicial error.” Glenn Def. Marine (Asia), PTE, Ltd. v. United States, 720 F.3d 901, 908 (Fed. 

Cir. 2013). There is no presumption of prejudice upon a showing that an agency acted 

irrationally. Sys. Stud. & Simulation, Inc. v. United States, 22 F.4th 994, 998 (Fed. Cir. 2021). To 

establish prejudice, Thalle must show that “but for the alleged error, there was a substantial 

chance that [it] would receive an award—that it was within the zone of active consideration.” 

Allied Tech. Grp., Inc. v. United States, 649 F.3d 1320, 1326 (Fed. Cir. 2011) (quoting Statistica, 

Inc. v. Christopher, 102 F.3d 1577, 1581 (Fed. Cir. 1996)). 

In this case, Thalle has demonstrated that it has been prejudiced by the Corps’ errors. In 

sum, the Corps assessed Thalle’s proposal with five significant weaknesses, seven weaknesses, 

and six strengths. AR 2164-66. On this basis, the Corps assigned Thalle’s proposal a Technical 

Merit rating of “Marginal” because its “proposal contains nearly as many significant weaknesses 
21

as it does strengths” and because the “risk of unsuccessful performance is high.” AR 2189.

Because Thalle’s proposal was assigned a “Marginal” rating, it was not considered for award, 

and the contract was awarded to P&J without conducting a trade-off analysis. See AR 2193.

The Court has now concluded that two of the significant weaknesses and two of the

weaknesses were assessed arbitrarily by the Corps. See supra Section III.A. Additionally, the 

Court has concluded that the Corps arbitrarily did not assess an additional strength to Thalle’s 

proposal. Id. While a revised count of strengths and weaknesses based on the Court’s findings 

may not result in offsetting strengths and weaknesses, the Solicitation does not necessarily

require a proposal to have offsetting strengths and weaknesses in order for it to be assigned a 

Technical Merit rating of “Acceptable.” See AR 17. The Solicitation defines an “Acceptable” 

proposal as one where the “[s]trengths and weaknesses are offsetting or will have little to no 

impact on contract performance.” Id. (emphasis added). Therefore, it is possible for Thalle to be 

assigned an improved technical merit rating of “Acceptable” based on a revised count of 

strengths and weaknesses and thus be considered for award. With price being equal to all of the 

other evaluation factors combined and Thalle’s proposed price being significantly less than 

P&J’s, Thalle has a substantial chance of being determined to be the best-value in a tradeoff 

analysis. While the Court finds that Thalle has met its burden of demonstrating prejudice, the

determination of whether Thalle’s revised combination of strengths and weaknesses “will have 

little to no impact on contract performance” is properly left to the Corps’ discretion. See 

FirstLine Transp. Sec., Inc. v. United States, 100 Fed. Cl. 359, 397 (2011) (stating that the 

assignment of technical ratings is a matter that is “within the broad discretion of the procuring 

agency”) (citing E.W. Bliss Co. v. United States, 77 F.3d 445, 449 (Fed. Cir. 1996)).

D. Thalle is entitled to injunctive relief.

The Tucker Act empowers the Court to “award any relief that the court considers proper, 

including declaratory and injunctive relief.” 28 U.S.C. § 1491(b)(2). When determining whether 

to grant a permanent injunction, the Court must consider: (1) whether the protestor has 

succeeded on the merits; (2) whether the protestor will suffer irreparable harm without injunctive 

relief; (3) the balance of hardships to the respective parties; and (4) the public interest. Centech 

Grp. Inc. v. United States, 554 F.3d 1029, 1037 (Fed. Cir. 2009) (citing PGBA, LLC v. United 

States, 389 F.3d 1219, 1228-29 (Fed. Cir. 2004)). Thalle has succeeded on the merits, so the 

Court must now consider whether Thalle will suffer irreparable harm, whether the balance of 

hardships favors granting the injunction, and whether the public interest is served by the 

injunction. 

The Court finds that Thalle is entitled to injunctive relief because Thalle has succeeded 

on the merits of its claim and the remaining injunctive relief factors weigh in favor granting such 

relief. See Contracting, Consulting, Eng'g LLC v. United States, 104 Fed. Cl. 334, 353 (2012) 

(“Although plaintiff's entitlement to injunctive relief depends on its succeeding on the merits, it 

is not determinative because the three equitable factors must be considered, as well.”) (citing 

PGBA, 389 F.3d at 1228-29). First, Thalle will suffer irreparable harm without injunctive relief 

because there is no adequate alternative remedy for its lost opportunity to fairly compete for the

contract. See Insight Sys. Corp. v. United States, 110 Fed. Cl. 564, 582 (2013) (highlighting 

“[t]he relevant inquiry in weighing this factor is whether plaintiff has an adequate remedy in the 
22

absence of an injunction”) (alteration in original); Sys. Studies & Simulation, Inc. v. United 

States, 146 Fed. Cl. 186, 203 (2019) (“The United States Court of Federal Claims has repeatedly 

held that a protester suffers irreparable harm if it is deprived of the opportunity to compete fairly 

for a contract.”) (citing cases). Second, the balance of hardships weighs in Thalle’s favor. 

Neither the government nor P&J allege how they will be harmed if Thalle is granted injunctive 

relief. Additionally, even though an injunction would result in a delay to the Corps’ project, only 

in exceptional circumstances would delay alone justify denial of injunctive relief. See Sys. 

Studies, 146 Fed. Cl. at 203 (stating “only in an exceptional case would [delay] alone warrant a 

denial of injunctive relief, or the courts would never grant injunctive relief in bid protests”) 

(alterations in original). Finally, the public interest weighs in Thalle’s favor because “the public 

interest in honest, open, and fair competition in the procurement process is compromised 

whenever an agency abuses its discretion in evaluating a contractor's bid.” PGBA, LLC v. United 

States, 57 Fed. Cl. 655, 663 (2003); see also Ernst & Young, LLP v. United States, 136 Fed. Cl. 

475, 519 (2018). Since all four factors weigh in Thalle’s favor, Thalle is entitled to its requested 

injunctive relief. 

IV. CONCLUSION

For the reasons stated above, Plaintiff’s motion for judgment on the administrative record 

is GRANTED. Both the Defendant and Defendant-Intervenor’s respective cross-motions are 

DENIED. Thalle is entitled to injunctive relief. Specifically, the Court ENJOINS the Corps 

from proceeding with performance of the contract awarded to P&J pursuant to the Solicitation. 

The Court ORDERS the Corps to reevaluate the proposals in a manner that redresses the errors 

identified in this Opinion. The Clerk is DIRECTED to enter judgment accordingly.

Some information contained in this Opinion may be considered protected information 

subject to the Protective Order entered on December 8, 2021. Accordingly, the Opinion is filed
