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

This is an architectural drawing set for a Weapons Handling Facility located in the Northern Division. The document consists of a comprehensive roof plan with detailed structural specifications, elevation views, and cross-sectional diagrams illustrating the facility's construction methodology and component specifications.

The roof plan indicates a repetitive structural bay system using Warren truss configurations spanning approximately 30 feet, with multiple bays arranged in a grid pattern. The drawing specifies typical roof construction details including 18" to 20" deep daily live loads, directional metal decking indicators, and roof drainage specifications. Key details include roof opening locations, all roof openings with specific dimensions and callouts, and provisions for equipment installations. The elevation and section views demonstrate the vertical structural relationships, truss connections, and building interface details. Additional annotations address construction sequencing, structural member sizing, connection details, and material specifications for the roof deck and supporting frame. The document includes graphic scales for reference and appears to be part of a larger construction document set, as evidenced by the sheet identification marking and revision block in the upper right corner. The drawing is prepared for the Northern Division and dated accordingly in the title block.
