NASA/JSC plans to issue a Request for Offer for replacing main substation switchgear and circuit breakers. This procurement is open to both large and small business and ranges between $1,000,000 and $5,000,000. This procurement is part of the Small Business Competitiveness Demonstration Program and is being conducted using the NASA MidRange procedures. The Standard Industrial Code is 1731 Electrical Work for the replacement and includes the following: Replace four existing oil circuit breakers (identified as OCB's D710, D730, D740, and D750) with new Government furnished equipment (GFE) 145kv, 2000A, SF6 gas breakers. The new gas circuit breakers will be Government furnished. The existing OCB's are mounted on "I" beams installed on pier type foundations. New conduit shall be installed between the new SF6 breakers and trench duct for signal and control cables. Because of shuttle flight restrictions, the installation and testing of each breaker shall require less than five (5) days. Remove 138kv Air Switch T3HS, 138kv OCB D700, 15 MVA Transformer T3 and switchgear 3. This removal will include all bus, support structures, cabling, Building 221F2 (contents included) and foundations. Relocate 25 MVA transformer 2 temporarily and re-install transformer 2. Repair foundation for transformer 2. Upgrade the 138 kv ring bus to 2000 amp capacity by replacement of the remaining 2-1/2 inch tubular bus with new 3-1/2 inch tubular bus. Replace two 138 kv, 1600 amp line traps with 2000 amp units mounted on new structures. Remove existing switchgear 2. This removal will include Building 221F1 (including it's contents), all interconnecting cables, and foundation. Construct new switchgear 2 Building 221F and install new Government furnished switchgear 2 lineup and remote operator panel. The new Building 221F will be located in the same area as the existing Building 221F1. This new facility and all other outdoor structures are designed for and shall be constructed to withstand 135 mph wind load. Replace existing 15kv bus duct between transformer 2 and switchgear 2, and between switchgear 2 and switchgear 1. Relocate the existing loads from existing switchgear 2 to switchgear 4 and 5. Remove the loads from existing switchgear 3 and connect to new switchgear 2. Upgrade switchgear 1 from 500 MVA to 750 MVA by replacement of existing air circuit breakers with new 750 MVA vacuum circuit breakers. Construct extension to switchgear 1 Building 221B. Provide and install new remote operator panel in the extension. Provide and install Allen Bradley remote I/O modules and cabnets to connect switchgear 1 and 2 to the existing Allen Bradley PLC system. Provide and install remote tap position indicators on the two existing Westinghouse transformers (T1 and T2). Disconnect and remove capacitor Bank 1 to improve access to Transformer 5. Reconnect capacitor Bank 2 to switchgear 1. ALTERNATE NO. 1 -- Replacement of one (1) 15 kv air switch at Building 7A, one 15 kv air switch at Building 14, one 15 kv air switch at Building 16A, one 15 kv air switch at Building 36 and one 15 kv air switch at Building 420.The existing oil filled 750 kva transformer at Building 14 will be replaced with a new liquid filled 750 kva transformer. NOTE: The base bid contains lead coating paint and Polychlorinated Biphenyl (PCB). The alternate contains only PCBs. The Government will handle the disposal of lead contaminated materials and debris resulting from the dismantling and removal of Building 221F1. The Contractor shall furnish a closed top, lined rolloff contained for accumulation of all lead contaminated debris. Construction will be completed within 584 calendar days after notice to proceed.
