B60 nuclear containments production facility consolidation, portsmouth naval shipyard (PNSY), kittery maine

The Naval Facilities Engineering Systems Command (NAVFAC) Atlantic is conducting market research through a Sources Sought Synopsis for the B60 Nuclear Containments Production Facility Consolidation at Portsmouth Naval Shipyard in Kittery, Maine. The project involves a major overhaul and renovation of Building 60's interior, including removal and replacement of existing mechanical and electrical systems, installation of building-wide sprinkler and fire alarm systems with interior fire pump and external generator, complete floor renovations with new layouts while preserving historic elements, and construction of an interior elevator tower to improve accessibility. The Navy is seeking qualified small businesses, including SBA certified 8(a), HUBZone, SDVOSB, WOSB, and EDWOSB firms, that can demonstrate experience with projects of similar size, scope, and complexity involving complete renovation of historic structures at least two stories tall on restricted sites. Interested contractors must submit capabilities packages including questionnaire forms and documentation of 3-5 relevant construction projects completed within the past 10 years that demonstrate experience with projects valued at $25 million or greater final construction cost. Responses are due by Thursday, August 21, 2025, at 14:00 EDT, submitted electronically with a 5MB limit and 10-page maximum for capability statements.

This opportunity is currently designated as a potential small business set-aside under NAICS code 236220 Commercial and Institutional Building Construction with a small business size standard of $45 million, though the government will use market research responses to determine whether to proceed with a small business set-aside acquisition versus full and open competition. The anticipated contract value ranges between $25-100 million and will be structured as a firm fixed price construction contract. The project specifically requires specialized experience in historic masonry building renovation and work in congested urban/industrial areas with limited laydown space. No incumbent contractors or current service providers are identified in the documentation. The government has structured the market research to assess contractor capabilities across multiple dimensions including past performance on similar large-scale renovation projects, current staffing levels with detailed labor category breakdowns, and compliance with federal contracting requirements including DCAA-approved accounting systems for potential cost-plus award fee task orders.
