• Installation of a new 400A, 4-pole, closed-transition ATS on an existing concrete pad.
• Installation of new conductors from the new ATS to the existing enclosed circuit breaker (main).
• Installation of a new government-furnished 200KW diesel generator with a 1200-gallon sub-base fuel tank and working platform on a new 11ft 6in x 22ft x 8" thick concrete pad.
• Installation of new conduit and conductors from the generator to the new ATS.
• Application of corrosion inhibitor to all terminations.
• Ensuring all new penetrations through exterior walls into the generator/MCC room are airtight to prevent hydrogen sulfide gas intrusion.

Building AS4300 (NRAS Douglas Gate Entry):

• Excavation and installation of a concrete border for a gravel pad.

• Installation of an equipment rack with a service panel and a government-furnished ATS.

• Installation of conduit and wire from the pole-mounted transformer to the service panel, and from the service panel to the ATS.

• Removal of the existing service disconnect, conduit, and conductors.

• Installation of a new 12" x 12" x 6" NEMA 3R junction box.

• Installation of a new 100" x 56" x 8" concrete pad for the generator.

• Installation of a 20' long 24" class V reinforced concrete pipe in the existing swale.

• Installation of #57 stone in the excavated area.

• Placement of a government-furnished 25KW generator with a 78-gallon sub-base fuel tank on the concrete pad and making all connections.

• Testing for proper operation.

• All electrical work must comply with NFPA 70, North Carolina State Building Code, and local codes.

• Equipment must be listed and labeled by a nationally-recognized testing agency.

• Systems must be complete and fully-functioning after installation.

• Testing of all equipment and wiring is required upon completion.

• All penetrations into the generator/MCC room at G575 must be airtight.

• MCB Camp Lejeune, North Carolina.

• Environmental requirements include awareness of potential contaminants, unexploded ordnance (UXO), and radiological concerns. Specific training and notification procedures are outlined.

• Coordination with utility providers for underground utilities is mandatory.

• Site visits are required to understand existing conditions.

Solicitation / RFP / RFQ

This document is a specification (Section 26 36 23) for Automatic Transfer Switches (ATS) and By-Pass/Isolation Switches. It details the technical requirements for these components, which are essential for ensuring continuous power supply in critical systems, likely in conjunction with generators.

• Automatic Transfer Switches (ATS):
