About this file
This document is a detailed Roof Plan drawing for Building 606 at the United States Military Academy, West Point, NY, prepared by the US Army Corps of Engineers. The roof plan includes 18 distinct roof sections with specific technical requirements, such as providing 5" average thickness isocyanurate insulation (R-30), modified bitumen roof system, tapered insulation to achieve 1/4" per foot surface slope, metal roof deck, roof drains, overflow drains, and adjustable pedestal systems with 24" square pavers. Additional specifications include installing salvaged coping stones, roof manufacturer's walkpads, fixed galvanized steel ladders, rooftop units, plumbing vents, and ballasted guardrails. The project is part of a repair and renovation effort for the General Instruction Building, with an issue date of 2 September 2025 and contract number W912DS19C0034.
