Attch 24 Coburn Gore 47PB0025R0044 QA V2 2025 12 10.pdf

Question Answer Date Received Date Responded Number Given the schematic nature of the project, the complexity, the considerable amount of unknown site/geotechnical information, the lack of specifications, etc., it is requested that the CMc Contingency Allowance listed in the Solicitation Section I.E.-2 be increased from 3% to 5%.

Please see Amendment 0001 to the solicitation. GSA's intent is to issue a future amendment that will contain additional technical information to alleviate this concern and the need to consider increasing the CMc Contingency Allowance.

09/23/2025 10/27/2025 0001 Many (but not all) projects in Maine buy fabricated and installed structural steel from Canada. Under the terms of the Buy America Act, and the high security nature of CBP, are construction managers allowed to consider/purchase these or other materials and services from Canada?

The Trade Agreements Act provides the authority for the President to waive the Buy American statute for eligible products from countries that have signed an international trade agreement with the United States. The value of the acquisition is a determining factor in the applicability of trade agreements.

Canada is a party to the World Trade Organization Government Procurement Agreement (WTO GPA) and Free Trade Agreements. The threshold for the WTO GPA is $6,708,000. As the Coburn Gore contract will exceed this amount, steel for this project can be purchased from Canada.

9/30/2025 10/27/2025 0001 Can GSA provide a sample or template of the Contract Price Form / CLIN structure to ensure cost segregation (base, housing option, IRA-eligible items) is formatted correctly?

The Contract Price Form contains separate tables for the Basic Requirement, Housing Options, Proposal Rates, and Unit Prices. The Basic Requirement and Housing Options tables contain mathematical instructions for each calculation. 10/15/2025 10/27/2025 0001

Small Business Socioeconomic Evaluation Factor (5%) - If an Other-Than-Small Business (OTSB) serves as the prime, and it forms a Contractor Team Arrangement (CTA) with a qualified Small Business, will the team receive credit (full or partial) under this evaluation factor? Or is evaluation credit limited only to primes that are themselves Small Businesses under NAICS 236220?

In the scenario raised, the Prime contractor would have to be a small business to receive any credit under the Small Business Socioeconomic Status evalutation criteria.

10/15/2025 10/27/2025 0001 The solicitation at Section II.F requires joint ventures to submit “financial information,” and the CASB DS-1 form references reconciliation with an entity’s financial accounting records. Can you please clarify whether audited financial statements (e.g., balance sheet and income statement) are required from all offerors as part of the initial proposal, or if they will only be requested during responsibility determination or when a joint venture or CAS-covered entity is involved?

In the case of a Joint Venture that qualifies as a small business, the Joint Venture entity must provide the financial information at Solicitation Section II.E.(4) with their proposal. In the case of a Joint Venture that qualifies as a large business, the Joint Venture entity must provide the financial information at Solicitation Section II.E.(3) with their proposal.

The Proprietary Information Agreement must be submitted with the proposal.

10/15/2025 10/27/2025 0001 The solicitation references multiple Design Narratives and PORs — should we submit acknowledgments for each, or is it sufficient to reference the final combined concept?

Reference the final combined concept when available.

In the event of an Offer being submitted by an SBA-approved joint-venture (JV), in which case the JV itself qualifies as a Small Business (and therefore qualifies for the SB socioeconomic 5% scoring), would the JV also be permitted to present past performance not performed as the JV, but performed independently by the member companies? For example, if a member of the JV is a large business with projects which meet all of the criteria of a “similar” project, would the JV receive the credit for those projects? The spirit of the 5% scoring is for it to go to actual small businesses, and not for it to be manipulated by large businesses through the JV loophole, correct? It would seem most fair that the member entities would have to decide between getting the SB scoring by submitting as a SB JV or getting the past performance scoring by submitting as a large business, but not both, correct?

Please see Solicitation Section II.F.(4). Representations and certifications, financial information, and past performance information must be submitted for each member of the joint venture.

10/15/2025 10/27/2025 0001 Please extend RFI due date to at least 11/5/25 as more RFIs are anticipated

Please see Amendment 0001 to the solicitation.

As discussed at the walk-through, FAR requires the SAM registration status for a joint venture (JV) to be “Active” at the time their offer is submitted to be considered for award. If the current government shutdown does not allow a new JV registration to be processed in time for the offer, how will this be handled or considered by the GSA?

If a potential Joint Venture offeror should experience issues with SAM registration, this information shall be provided to the CO as soon as it becomes know.

10/22/25 10/27/2025 0001

Master Attachment 15 – “Coburn Gore LPOE Final Concept Submission Combined REV 08-11-25” is not listed as a CUI document in the Solicitation. However, the associated content is stamped with bold or highlighted red font noting, “PROPERTY OF THE UNITED STATES GOVERNMENT This is controlled unclassified information. Do not remove the CUI marking. Properly destroy or return documents when no longer needed. Controlled By:

GSA (Records@gsa.gov)”. In a September 30, 2025 email from GSA, we received confirmation that the document was not marked CUI. The file name was not marked but the documents clearly are.

Therefore, we respectfully request that the CUI markings be redacted/removed based on your confirmation that the document is not marked CUI and redistributed for intended use. As a CMMC level 2 certified company and as the individual pages of the document are marked as CUI, the document will need to be handled as CUI as otherwise our certification is jeopardized.

Please see Amendment 0001 to the solicitation. Master Attachments 14 and 15 are now marked as CUI.

10/24/25 10/27/2025 0001 Please confirm the CMc will not be held to the Target ECW CLIN 0002 and reaffirm this is solely used for evaluation purposes for the selection of the CMc. The only CLIN that the CMc will be held to is CLIN 0001 “Design Phase Services (Firm Fixed Price) – Includes all Housing Options.” Our understating is the GMP will be established at roughly 75% design.

The CMc contract includes design phase services at a firm-fixed-price (FFP) and an option(s) for construction at a Guaranteed Maximum Price (GMP). The GMP, which includes the Estimated Cost of the Work (ECW), CMc Contingency Allowance (CCA) and Fee, is the construction ceiling price described by Federal Acquisition Regulation (FAR) Subpart 16.403. The GMP is established at contract award. As is the case for Coburn Gore, the GMP may be established as one option or as multiple options, with separate GMP amounts.

The GMP may be bilaterally modified upward during the design phase ONLY for approved additions to the scope of work. The GMP may be bilaterally modified downward during the design phase for deletions to the scope of work 10/24/25 10/27/2025 0001

As the government is currently shutdown, please advise what the impact may be on the project and proposal timeline.

It is not yet known what impact, if any, the current lapse in appropriations will have on the Coburn Gore CMc solicitation. All potential offerors will be notified of any changes, should they occur. 10/24/25 10/27/2025 0001

Who is responsible for the primary electrical work? Will that be provided by GSA? Please confirm the extent of the primary electrical work, compared to secondary and building distribution systems.

As communicated during the site walk through, the three phase power installation to the site from Hydroquebec is the responsibility of the CMc as part of the pre-enabling work.

GSA has established a customer record with Hydroquebec (HQ), and HQ requires a Quebec licensed master electrician contracted to continue the execution of the three phase power installation. It is expected the HQ will perform all of the utility line work to carry three phase across the border from Canada. Also, GSA expects that HQ provide the transformers for the LPOE and the Housing. exact locations TBD. GSA will lead the communication between HQ and the CMc contracted to execute the work. (GSA is also sorting out the presidential permit requirements of cross border utility work between Dept of Energy and Dept of State and will advise of any potential impacts to this scope to the CMc). Secondary and building distribution systems are also the responsibility of the CMc. 10/21/2025 12/10/2025 0002

Contract documents contain conflicting dates for Substantial Completion and Notice to Proceed:

A/E SOW Section 6 (Page 17): February 16, 2029 CMa SOW Section 2.3 (Page 10): December 15, 2028 CMc SOW Section 4.a (Page 12): February 16, 2029 CMc Agreement Section I.C.(2)(b) (Page 6): "37 months from

NTP"

NTP listed as both July 6, 2026 (CMc SOW Page 12) and September 15, 2026 (A/E SOW Page 17)

Please clarify:

What is the official contractual Substantial Completion date for the

LPOE?

What is the confirmed Construction NTP date?

Are there separate Substantial Completion dates for LPOE vs.

Housing components?

This affects project schedule development, milestone planning, and coordination with all project team members.

The documents were prepared and gathered while the concept design workflow was active. The housing design has evolved much slower than initially anticipated since the posting.

Presently our internal tracker indicates the following: CMC award: estimated April 2026, Construction start: estimated April 30, 2027, susbtantial completion: estimated April 30, 2030. The CMc is expected to develop a phased construction plan with GSA and CBP to enable the land port to remain in continuous operation and the housing to remain available to officers uninterrupted. GSA and CBP anticipates two separate CPM schedules tracking the LPOE construction and the Housing program construction on separate paths, with a confirmed phasing plan and logistics plan developed together after award

10/21/2025 12/10/2025 0002 Drawings show Primary/Inbound Inspection Booths (Qty: 3) and Secondary/Outbound Booth (Qty: 1), but materials and specifications are undefined. Please clarify: (1) What is the construction type (prefab modular, concrete, masonry, steel frame, or other)? (2) Are booths permanent, semi-permanent, or temporary?

Please refer to sheets A-432, A-433 for more information regarding the design of the inspection booths. Each booth will be a prefabricated, steel framed booth with overhead infrared heating lamps, resistant heating mats on the floor, a DX cooling unit in each booth, and OA provided from a duct routed down through the basement and out to the facade of the CIB. The exterior cladding of the booth is TBD, but will need to be robust and salt resistant (the design team is considering fibre cement and metal). The booths are designed to be pre-fabricated and hoisted into place, with MEP hookups accessible from a hatch in the upper floor level. The are designed to be permanent, but easily replaceable when they take too much wear and tear. 10/21/2025 12/10/2025 0002

Per the NEPA contracotr: Right now, the only mitigation measures are for the Canada Lynx:

Avoid tree clearing and disturbance to the extent practicable between May 1 and July 15 to avoid the breeding and denning season of Canada lynx.

If work must be conducted between May 1 and July 15, work crews or an environmental monitor should be trained to perform a pre-construction walkthrough of the area and inspect for evidence of Canada lynx dens or Canada lynx (sightings, tracks, scat, etc.). If Canada lynx evidence is observed within 100 ft of the site, do not proceed with construction until after July 15.

Brief project personnel on avoiding Canada lynx and preventing vehicle collisions (drive slowly and during daylight hours as much as possible).

Schedule construction work during daylight hours to minimize trips during the dusk and dawn periods when Canada lynx are most active.

Any permanent fencing must be permeable to wildlife to allow any trapped Canada lynx to escape.

Install temporary fencing around any open pits to prevent Canada lynx from falling in, and/or place ramps into any pits or trenches for Canada lynx to escape if they fall in. 10/24/2025 12/10/2025 0002
