Please confirm whether a Small Business Subcontracting plan is required, and what if any subcontractor participation goals are required.

The plan is required from the apparently successful offeror prior to contract award, not with the initial proposal. Please see GSA's subcontractor small business goals https://www.gsa.gov/small-business/get-started.

20 Document 01, Solicitation Section II.D (Technical Proposal) indicates that “all other pages (including the cover page) are included in the page limitation.” To improve clarity and organization of the response, may the cover page, table of contents, and section tabs be excluded from the page limit?

It is not readily apparent what, if any, documentation is considered CUI. Please confirm the documents designated as CUI, or confirm that this is not applicable, considering that the inclusion of CUI significantly increases the compliance requirements and may limit the pool of contractors able to participate in the project.

Revised documents have been uploaded to sam.gov with the required CUI Markings under Amendment 0003. See question 11 for the revised documents.

22 Please confirm whether previously completed CPARS and PPQs may be submitted, or if new ones must be obtained.

24 What does UCI mean on the docs uploaded to SAM.Gov? Controlled Unclassified Information (CUI) is sensitive, non-classified federal information requiring safeguarding or dissemination controls. It is created or possessed by the government (or contractors) and, while not classified under Executive Order 13526, must be protected according to laws and policies, often managed via NIST SP 800- 171.

25 Unclassified Control Information? Can I send these docs to my subs who are bidding? Do the subs need to sign non disclosure form provided? I believe we have to sign (the offerer) and send to you prior to submission, correct?

Yes, contractors registered on SAM.gov are authorized holders and may share solicitation documents marked as Controlled Unclassified Information (CUI) with potential subcontractors for a lawful government purpose, such as bidding.

Please adhere to the following security requirements:

- Email Distribution: Any documents sent via email must be password protected.

- Physical Copies: Documents must be kept in a secured location and protected by a physical barrier, such as a folder or a locked cabinet, when left unattended. Any printed documents must be shredded after use.

- Direct Access: Alternatively, subcontractors may register to access the documents directly via SAM.gov.

Please note that CUI replaces former designations such as "For Official Use Only" (FOUO) and "Sensitive But Unclassified" (SBU). A non disclosure form is not required to share CUI marked documents for this solicitation.

26 Also, provided checklist says submit subcontracting plan, however in the solicitation under subcontracting section states not needed at this time. Please clarify if we should submit one with this submission or wait until after award.

39 Reference Amendment 0003. We have successfully downloaded ten (10) of the eleven (11) CUI‑marked files issued as part of Amendment 0003 to our secure enclave.

However, one file appears to be missing and remains unavailable for download: “Attachment 11 – Drawings dated 2025‑10‑13 (11 Drawings 2025 10 13.pdf).” Please provide the missing file or confirm when it will be made available to ensure bidders have access to the complete and current set of solicitation documents.

The file has been availble and ready to request access since amendment 0003 was issued. CO has confirmed you have access.

40 "Reference Amendment 0003. Eleven (11) files, identified as Attachments 10 through 20, were deleted from SAM.

gov and subsequently re issued, with the exception of Attachment 11 (Drawings dated 2025 10 13, 376 pages).

The re issued documents now include Controlled Unclassified Information (CUI) markings at the top of each page, whereas the previously posted versions did not.

Please clarify the following:

CUI Applicability Review:

We formally request the Government conduct and confirm a review of all re issued attachments currently marked as CUI to verify whether CUI designation is appropriate and necessary for each document, consistent with applicable CUI guidance and criteria.

Document Supersession and Authorized Use:

Confirm whether the previously posted, unmarked versions of the re issued attachments are fully superseded and no longer authorized for use, and whether bidders are required to rely solely on the re issued CUI marked documents for proposal preparation, pricing, and subcontractor solicitation.

Safeguarding and Handling Requirements:

For any documents that remain designated as CUI, please clarify the specific safeguarding, handling, storage, and distribution requirements bidders and their subcontractors must comply with when accessing and using these materials.

Disposal of Previously Issued Unmarked Documents:

Provide direction regarding the proper destruction or deletion of any electronic and hard copy versions of the previously issued, unmarked attachments that may have been downloaded, printed, or distributed prior to re issuance. Please clarify whether certified deletion, document destruction, or other disposition actions are required, and whether bidders must confirm compliance.

Industry and Subcontractor Availability Impact:

Additionally, please advise whether the Government has considered the likely impact on competition should all re issued documents remain designated as CUI. Broad application of CUI markings may significantly limit bidders’ ability to solicit and engage subcontractors, as a substantial portion of the subcontractor marketplace is not currently compliant with CUI safeguarding requirements.

This condition could adversely affect pricing, schedule, overall bid participation, and project execution."

"Yes, contractors registered on SAM.gov are authorized holders and may share solicitation documents marked as Controlled Unclassified Information (CUI) with potential subcontractors for a lawful government purpose, such as bidding.

Please adhere to the following security requirements:

- Email Distribution: Any documents sent via email must be password protected.

Please note that CUI replaces former designations such as ""For Official Use Only"" (FOUO) and ""Sensitive But Unclassified"" (SBU). A non disclosure form is not required to share CUI marked documents for this solicitation.

41 The Solicitation indicates that Requests for Clarification or Interpretation are due by April 27, 2026. Given the significant volume and complexity of documents associated with this project, we respectfully request that the deadline for submitting questions be extended by three (3) weeks. This additional time will allow Prime Contractors and their Subcontractors to complete a thorough review of the solicitation documents and submit informed and meaningful clarifications.

Request for Clarifications and Interpretations has been extended to May 20th, 2026 by 2:

42 The Solicitation identifies May 28, 2026 as the proposal due date. Should certain RFP documents remain designated as Controlled Unclassified Information (CUI), additional time will be required to identify, evaluate, and engage subcontractors that are compliant with CUI safeguarding requirements. Accordingly, we respectfully request that the proposal due date be extended by a minimum of four (4) weeks to allow sufficient time for compliant subcontractor outreach, coordination, and proposal development.

The proposal due date has been extended to June 4th, 2026 by 2:00 PM EST.

43 Please confirm whether the full AV, Security, and Telecommunications scope is included under the Electrical Subcontractor, or if only the boxes, raceways, and pull strings shown on the Electrical Drawings are part of this contract, with the balance by others. On some prior federal projects, portions of this work have been performed by separate Government-retained contractors, so we request clarification on the intended scope for this project.

Security and Telecom system are 100% included in contract. The AV system boxes, raceways and pull strings by contractor;

equipment and cable will be furnished and installed by NPS.

Height of flood barriers to match the height of existing granite water table. See Building Elevations.

45 The solicitation doc says it's not required to be submitted with offers, but the proposal contents checklist in Section II. A lists the subcontracting plan as one of the required submission docs. Please clarify

Refer to RFI #23 and #31

60 Specification 01 11 00 Section 1.12 A. states normal business working hours of 8:00am to 4:30pm. Would GSA/NPS be agreeable to starting at 7:00am and off hours/weekends if needed?

City of Boston regular construction hours are 7 AM to 6PM weekdays. Due to the proximity of residential abutters, work requests outside these hours will be dependent on review by federal and local authorities. Additionally, The Boston Municipal Code sets standards for reasonable noise levels. It also sets maximum acceptable noise levels for different times of day. An unreasonable level of noise is anything louder than 70 decibels at any time, except for permitted construction. Compliance with these requirements is a condition of the contract.

61 Drawing Sheet C1-0 Proposed Demolition shows that the existing concrete sidewalk along Third Avenue will be removed and replaced. Is this a City of Boston owned sidewalk requiring City permitting/approval?

Yes

62 Can work such as site prep and demolition commence before all work plans are submitted and approved?

Work can proceed once NTP is issued.

63 Please indicate where the information required in RFP Section II. E (Other Information to Submit with Proposal) should be included, i.e., in Price Proposal or Technical Proposal? And we assume this information does not count toward the 45 page limit, correct?

Other information to submit with proposal is not a submital for the technical proposal and does not count toward the technical proposal page limit. The technical proposal has been increased from 45-pages to 60-pages.

64 Please clarify where the JV Agreement is to be included in our proposal (i.e., Price Proposal or Technical Proposal).

If included in the Technical Proposal, please confirm it is excluded from the 45-page limitation as it would require up to 50% of the allotted 45 pages.

The JV agreement is not a submittal requirement for the technical proposal therefor isn't apart of the 60-page limitation.

65 Solicitation Section II.E. Other Information to Submit with Proposal (2) Qualifications of Offerors page 14 of 51.

Does GSA Form 527 – Contractor’s Qualifications and Financial need to be submitted for each JV member/partner? If so, can the information be submitted directly to GSA? If so, to whom and how?

Please ensure that a GSA Form 527 is submitted with the proposal for each Joint Venture member or partner.

66 The RFP currently does not exclude the Reps & Certs from the page limitation…we’re assuming this would be included as part of the Price Proposal and therefore excluded from the 45-page limitation?

The Reps & Certs is not a submital of the technical proposal and is excluded from the 60 page limitation.

67 Do the three example Similar Projects required in Factor 2, Company’s Experience, need to be the same Similar Projects required in Factor 3, Company’s Past Performance?

Yes. Solicitation page 11 under Factor 2.

"Note: Reference “Definitions” above in the “Technical Proposal” section. Offerors must not submit more than three (3) Similar Projects to satisfy the submittal requirements of both evaluation Factor 2 and Factor 3."

68 If additional key personnel beyond the Project Manager and Onsite Superintendent are provided in our proposal, will the additional personnel be considered more favorably from an evaluation perspective?

At a minimum, the key personnel for the project must consist of the following positions: Project Manager On-site Superintendent
