J061--Building 65 Switch 1 Repair at VAMC Central Western MA
The solicitation has been amended to include a medium-voltage electrical one-line diagram that vendors must review for system configuration, isolation points, and load connections. Responses to RFIs clarify that Switch 1's downstream loads include the B65 breaker, SW2, and TR15, while Building 15 provides alternate/emergency power via an ATS and generator. The contractor is responsible for all switching, lockout/tagout, grounding, and restoration of upstream medium-voltage equipment; VA personnel will not perform these operations. Arc-flash values and protective-device settings must be field-verified, but for planning assume arc-flash values are less than or equal to 40 Cal/cm², and VA electrical-shop support will not be available during shutdown. All other terms and conditions of the solicitation remain unchanged.
