2.4.1(j) Attachment J-C54 As-Bilt 3 Roof Plan 3 T&E Lab.pdf

This is an architectural drawing document for a Weapons Handling Facility under the Northern Division. The drawing presents a detailed roof plan with structural framing specifications for a building approximately 90 feet by 30 feet. The roof plan illustrates nine structural bays (labeled U1 through U9) with typical 30-foot spacing, featuring a truss system with specific dimensional callouts and load calculations noted throughout.

The document includes multiple detailed sections and elevation views showing vertical bracing, roof construction details, and connections. Key specifications indicate typical roof composition to be 18" to 20" duct work with roof deck noted in the details section. Additional notes specify that arrows indicate direction of metal deck, roof drains are labeled as such (R.D.), and all roof openings require specific sizing and location documentation. The drawing includes graphic scales, a north arrow, and references to sheet B0081 as the primary drawing sheet. The revisions table in the upper right corner tracks multiple revisions to the design. This appears to be a construction document providing the structural and architectural specifications necessary for building the weapons handling facility.
