Convert Sprinkler System from Dry to Wet, Building 4224

The Naval Facilities Engineering Command is seeking to convert the fire sprinkler system from dry-pipe to wet-pipe configuration in Building 4224 at Marine Corps Air Station Cherry Point, North Carolina. This procurement involves modifying the existing fire protection sprinkler system with hydraulic calculations based on fire hydrant flow tests, requiring 100% coverage of designated areas including electrical and mechanical spaces, and compliance with NFPA 13 standards. The solicitation is restricted to Mechanical MACC (Multiple Award Construction Contract) contractors, with only three eligible firms authorized to submit proposals: Mechworks Mechanical Contractors, North State Mechanical, and R&W Construction Company. A Qualified Fire Protection Engineer must review submittals, perform construction surveillance, and witness testing, with extensive documentation requirements including hydraulic calculations, shop drawings, and operation manuals. Key dates include a mandatory site visit on August 26, 2025 at 0930, with contractors required to submit attendee lists by August 19, 2025, an RFI deadline of August 29, 2025 at 0900, and proposal submissions due September 5, 2025 at 1200 local time. The government intends to evaluate proposals and issue a task order without discussions, requiring contractors to submit their best initial pricing.

This procurement is designated as a Total Small Business set-aside under NAICS Code 238220 for Plumbing, Heating, and Air-Conditioning Contractors. The three pre-qualified contractors eligible to compete are all North Carolina-based firms within the Mechanical MACC framework, ensuring competition remains within the established contractor pool. The estimated contract value ranges between $250,000 and $500,000, reflecting the complexity of converting the fire suppression system infrastructure. The contract requires completion within 120 calendar days after award, establishing a relatively tight timeline for the sprinkler system conversion work. Performance will occur at Marine Corps Air Station Cherry Point, North Carolina, requiring contractors to comply with Davis-Bacon wage requirements and Executive Order 14026 minimum wage provisions. The project involves technical work including steel piping installation, sprinkler components with specific K-factors, and comprehensive testing protocols to ensure fire protection system reliability.
