About this file
This is a structural engineering drawing document from Naval Facilities Engineering Systems Command (NAVFAC) detailing repair work at Portsmouth Naval Shipyard in Kittery, Maine. The drawing sheet SF506, dated with final submission on October 1, 2025, and amended on March 10, 2026, provides detailed structural specifications for Building 60 repairs, specifically focusing on four primary support details.
The document includes: (1) Heat Exchanger Support Frame Detail (A2), which specifies installation of a 3x3x3/8 steel post support system with 1/4"x4"x4" base plates and 1/2" diameter stainless steel expansion anchors requiring 2.5" minimum embedment, with dimensions to be coordinated with actual heat exchanger equipment; (2) Attic Piping Support Detail (C2), which requires installation of galvanized joist hangers with 700 pound minimum capacity supporting 2x6 joists spaced 7 feet apart typical, tied into existing 2x8 joists and wood plank attic walkway; (3) Compressed Air/Electrical Hose Reel Support Detail (C4), featuring 1-5/8"x1-5/8"x12GA slotted channel cross beams at each reel with cable bracing, requiring threaded rod concrete anchors with 1.75" minimum embedment and a ground penetrating radar survey to locate existing slab reinforcing before anchor placement; and (4) Typical Existing Girt to C8x11.5 Door Jamb Detail (A4), specifying drilling and bolting connections using 3/4" diameter A325N bolts with 3" gage spacing. All work involves coordination with existing structural elements at the naval facility, with design approval by the ROICC (Resident Officer in Charge of Construction) Portsmouth Naval Shipyard.
