About this file
This architectural drawing is a detailed roof plan and skylight design for Building 606 at the United States Military Academy, West Point, NY, prepared by the US Army Corps of Engineers. The document (Sheet A-122) provides comprehensive roof plans for multiple roof sections (Roofs #9, #11, #15, and #17) and includes intricate details for areaway skylights, with specific technical specifications for roofing materials, drainage, and installation requirements. Key technical notes include providing 5" average thickness isocyanurate insulation (R-30), modified bitumen roof system, tapered insulation to achieve 1/4" per foot surface slope, metal roof decking, roof drains with 30" sumps, and specific instructions for coping stones, penetrations, and guardrails. The project is part of a repair contract for the General Instruction Building, with the solicitation number W912DS19C0034 and an issue date of 2 September 2025, indicating a current active federal construction project.
