Please see solicitation and all applicable attachments. Please be advised that only Contractors of the Small Business Indefinite Delivery / Indefinite Quantity (IDIQ) Multiple Award Construction Contract (MACC) for Utility Mechanical Construction, Primarily in the Hampton Roads, Virginia Area of Responsibility (AOR) (Contract Nos. N4008523D0043/0044/0045/0046/0047/0048) can provide a proposal for this project [Extend 35kV Circuit from Navy South Substation to SA Substation at NSA HR, Norfolk, VA]. Contractor must provide supervision, labor, material, and equipment required to perform all work for the following project: Extend 35kV Circuit from Navy South Ckt #5 to Switch 232. This project will extend a 34.5 kV underground circuit from Navy South Switching Station circuit #5 (NS-5) to existing Switch #232, way 1. This underground circuit will replace NS-15 overhead circuit as the primary 34.5kV line for the SA Substation. The NS-15 overhead circuit will then provide redundancy for the SA Substations. Demolition work includes circuit NS-5 from Navy South Switching Station from existing circuit breaker to electrical manhole (EMH) #3803 to EMH #3804 to EMH #3805 to EMH #3746 to EMH #3745 to EMH #3744 to EMH #3743A. New work includes providing 3-1/C #750kcmil 35kV EPR and 1#4/0, 600V Cu ground from existing circuit breaker #5 in Navy South Switching Station to Switch 232 way 1 through the existing underground ductbank system from EMH #3803 to EMH #3408B. Refer to NAVFAC Executable Scope Work Order No.: 1747833 (Attachment A) for additional information.
