About this file

This is Amendment 0003 to Solicitation ACQR6148962, issued by NAVFACSYSCOM Mid Atlantic PWD New London at Naval Submarine Base New London, Groton, Connecticut. The amendment is effective March 11, 2026, and extends the proposal due date to March 26, 2026, at 12:00 PM EST. The amendment addresses responses to six Requests for Information (RFIs) related to a mechanical, electrical, and plumbing project involving Make-Up Air unit (MAU) replacement and related infrastructure work.

The RFI responses address electrical system capacity assessment, including as-built information for electrical panels (Panels A-D) and Main Distribution Panel (MDP) with breaker schedules. The government confirmed that only 1999 as-built drawings are available and provided 11 attached photographs of electrical panels. Regarding electrical demand load verification, the government indicated that Advanced Metering Infrastructure (AMI) data is unavailable due to distribution fiber failure and scheduled PWD electricians to meter the MDP to determine current load demand. The amendment clarifies project scope for multiple CLINs, including MAU #1 replacement within two days (CLIN 0001), MAU #2 replacement (CLIN 0002 with extended one-week timeline if accepted), temporary make-up air provision for one month (CLIN 0003), and roof curb and ductwork replacement (CLINs 0005-0007). The contractor is not required to sign and return the amendment document. Offerors must acknowledge receipt of this amendment prior to the extended proposal deadline or risk rejection of their offers.

AMENDMENT OF SOLICITATION/MODIFICATION OF CONTRACT 1. CONTRACT ID CODE PAGE

1) As follow-up to RFI 006. It appears that the as-built information on Drawing E6 (attached) does not reflect current conditions. Further information will be needed to determine available power. Please provide pictures and/or updates to the as-built of each of the electrical panels and any sub panels (Panels A-D) to allow confirmation of existing breakers and loads.

Answer: B562 asbuilts (1999) are the only drawings we have on file. See 11 each attached photos (including breaker schedules) of MDP and Panels A-D.

2) As a follow-up to RFI 006. It appears that the electrical service feed via a 300 kVA transformer and demand load (as of 1999) on the electrical service was 123.6 kVA. Please confirm current demand load and that the 1999 as-built information is still accurate. If this cannot be confirmed, please provide 12 months of electrical metering data for the kWH meter mounted on the secondary side of the pad-mounted transformer feeding the service. This information is required to confirm the demand load if not clearly confirmed by the government. A current demand load assumption is required to provide our basis of bid estimate.

Answer: Advanced Metering (AMI) electrical data is not recorded/available at B562 due to distribution fiber failure in that area. We're going to schedule our PWD Electricians to meter the MDP to provide an idea of its current load demand. We'll follow up with the metering results.

3) Please provide an extension of two weeks following responses to final RFIs to allow for DOR and MEP vendors to receive adequate time to receive equipment quotes as the power consumption issue tremendously impacts the proposed solution to meet the government's needs.

Answer: Proposal due date has been extended.

4) CLINN003 states to provide Temporary MakeUpAir for one month. Please provide information on how you anticipate that we will be able to provide MakeUpAir to the space since we will not be able to connect a temporary unit to the existing MAU ductwork?

Answer: Means and methods is up to the Contractor. One idea, without using the existing ductwork, would be to run temporary exterior flex duct, with branches supplying each storage area through their exterior doors.

5) Will you assume that if we have provided pricing for CLIN 0003 that we have not included replacement MAU #1 within the two days as per scope of CLIN 0001? And that CLIN 0003 will need to be accepted in order to complete the project?

Answer: If the roof curb does not need replacement, it's the gov't position that 2 days should be enough time to remove exist and install new MAU, provided the crane and equipment is onsite, and any electrical/mechanical prep work is done. If you're replacing roof curbs, or entire ductwork (CLIN 0005-0007), it's the gov't position that CLIN 0003 would be needed.

6) CLIN 0001 states pricing is to be based on replacing MAU #1 in two days. If CLIN 0002 is accepted will we be required to replace both units in two day

Answer: Regarding MAU #2 (CLIN 0002), although we need fresh air in the shipping/receiving area, it's not as critical as the 2-day requirement for MAU #1. We could make do (i.e. open doors for fresh air) for a week, especially if this work is not being done during the winter.
