Update 1 June 2026:  Late RFI:  The Virginia Electrical Code is based on NFPA 70 (2020 Edition) with state amendments, adopted through the 2021 Virginia Uniform Statewide Building Code. NEC 230.70(A)(1) requires the service disconnecting means to be installed at a readily accessible location either outside the building or inside nearest the point of entrance of the service conductors. On Sheet E-110, the new service-rated disconnects ATS-A and ATS-B appear to be located in a room separated by a wall from the room where the service conductors enter the building. The service conductors appear to route across the wall prior to termination at the ATS units. Please confirm that the proposed configuration is compliant with NEC 230.70(A)(1), or advise if any modifications to the installation are required for compliance. Answer:  This is a federal installation and therefore the UFC adopts the 2026 NEC, not the Virginia Electrical Code. All work must comply with the 2026 NEC. The building is not supplied by a utility and therefore, by definition in the NEC, the conductors entering the building are feeders, not service conductors. The equipment is not considered service equipment. 2026 NEC, 225.31(B) exception #1 allows the disconnecting means for the building to be installed in the location shown on the plans. Update 22 May 2026:  Corrected error on page 1 of IFB solicitation. Block 13 now has the X for the bid guarantee. This was called out in FAR 52.228-1. 20% bid guarantee required. See new solicitation document in the attachements. IFB extended to 2 June 2026, end of day. Bid opening 3 June 2026 at 10am. See below.  There appears to be a conflict between the one-line diagram on Sheet E-602 and the new work power plan on Sheet E-110 regarding the secondary feeder from XFMR T58 to ATS-B. On E-602, this feeder is identified as 3200.4 (9 sets of 4-#500 KCMIL, 4" conduit), which per the feeder schedule appears to indicate new conduit installation. However, Sheet E-110 references Keynote 2 along the same routing, which directs conductors to be installed within existing underground conduits, consistent with the parallel T57-to-ATS-A feeder identified as 3200.4U. Please confirm whether the T58-to-ATS-B feeder is intended to: Reuse existing underground conduit infrastructure, in which case the feeder designation should read 3200.4U; or Be installed in new conduit, in which case Keynote 2 would not apply to this feeder run. Answer:  The intent is to reuse the existing conduit infrastructure for the T58 to ATS-B feeder. That feeder on E-602 should have been identified as 3200.4U. RFI's:  All building power outages are to take place on weekends, holiday breaks, or times when there will be no occupants in the building.  Correct. As this building will be occupied, we cannot have power interruptions during normal working hours. Please confirm per the site visit comments - Contractor is not required to provide backup generators or backup power for weekend outages to take place. Confirmed. The contractor is not required to provide a backup generator or power for weekend outages. ------------ Update: Revised Attachment 1 - Plans attached. See redaction on page E-001 removing specific language about the portable generator.  ------------ Continuation Page Defense Supply Center Richmond (DSCR) Generator Tie In This is a solicitation for construction prepared in accordance with the format in FAR Part 14 and FAR Part 36, as supplemented with additional information included in this notice.  The solicitation number SP4703-26-B-0001 is issued as an Invitation for Bid (IFB).  The resulting contract will be a firm-fixed price award with an expected Period of Performance of 365 days from the issuance of the Notice to Proceed.
