About this file
This is a structural design drawing for Building 60 repairs at Portsmouth Naval Shipyard in Kittery, Maine, prepared by the Naval Facilities Engineering Systems Command (NAVFAC) Mid-Atlantic. The drawing depicts a Second Floor Ceiling Framing Plan at a scale of 1/8" = 1'-0" and shows the layout of existing and proposed structural elements within the attic space of an industrial building. The document is classified as UNCLASSIFIED and was finalized on October 1, 2025, with Amendment 008 issued on March 10, 2026.
The drawing specifies existing structural conditions including brick masonry walls, built-up steel building columns, steel bridge crane columns, steel framed gable roof trusses, and 2x8± wood ceiling joists spaced 3'-0" on-center. Proposed work includes installation of a steel ladder mounted to the wall with 7" clearance from wall to centerline of ladder rungs; (2) 2x8 wood header beams; (1) 2x8 filler joist; 2x6 rough sawn wood plank walkway; closure of existing access hatch doors; (1) 2x8 joist attached to existing joists; and (2) 2x6 supplemental framing for piping support. General notes specify that no material storage or staging is permitted on attic floor framing without temporary shoring with approved engineered design, and all temporary planking must be removed upon work completion.
