About this file
This is an architectural drawing sheet for the Portsmouth Naval Shipyard in Kittery, Maine, specifically detailing wall sections for the B72 Resiliency Improvements project. The drawing is classified as unclassified and was prepared by Naval Facilities Engineering Systems Command (NAVFAC) Mid-Atlantic under contract number TBD with project number P-1112 B72 Resiliency Improvements. The sheet (A-500) contains multiple wall section details at various scales (3/4" = 1'-0" and 1 1/2" = 1'-0") showing typical construction assemblies for the B72-Addition structure, including pump rooms B, S, and adjacent spaces.
The wall sections illustrate construction details incorporating standing seam metal roof systems, 4-inch insulated metal wall panels, 8-inch concrete back-up walls, 2 3/8-inch concrete-faced rigid insulation boards, vapor barriers, structural frames by MBM, and various fire-rated wall assemblies (2-hour and 3-hour rated). The drawing includes termination bar details and notes specifying that girt spacing will be determined by MBM and that air-vapor barriers must be sealed to all roof fabric and penetrating structures. The revision date is August 25, 2020, with the drawing file dated April 10, 2026, indicating ongoing project management of these specifications for naval shipyard resiliency improvements.
