Submarine Support Facility
Location: San Diego
Client: Naval Facilities Engineering Command
Completion Date: 2000
This project was the design of a Submarine Support Facility (SSF) at Naval Submarine Base San Diego (SUBASE). The SSF performs maintenance and repair services required for nuclear-powered submarines homeported at SUBASE San Diego. Design features:
- Structural slab foundation supported on precast concrete piling; soil conditions required vibro-compaction and vibro-replacement techniques to reduce liquefaction potential due to a seismic event
- Special concrete construction
- Smooth, crack-free concrete surfaces for all walls and floors
- Floating post-tension wearing slab
- Increased emphasis on structural tightness to support negative pressure ventilation
- HVAC system with special HEPA filter system
- Use of materials with low radon levels
- Containment and treatment of radiological liquid waste
- 10-ton bridge crane
- Liquid processing area
- Controlled material storage area
- Access point room
- HEPA filter room
- Clean work/gage calibration room and personnel decon room
- Mechanical and electrical rooms
- Parametric estimating and programming documentation (PEP)
- Final design, plans and cost estimating
- Construction support services
