About this file
This document is a roof plan drawing for Building 606 at the United States Military Academy (West Point), prepared by the US Army Corps of Engineers. The roof plan (Sheet A-120) details a comprehensive roofing system renovation with multiple specific requirements, including: installing 5" average thickness isocyanurate insulation (R-30), modified bitumen roof system, tapered insulation to achieve 1/4" per foot slope, metal roof deck, roof drains with 30" sumps, overflow drains, and various mechanical and plumbing penetrations. The project involves multiple roof sections (Roof #1 through #18) with specific installation instructions for elements like rooftop units, dunnage, walkpads, salvaged coping stones, and mechanical equipment integration. The drawing is part of project number 94078 for the New York District, with an issue date of 2 September 2025 and is marked as Addendum #2 for repair of the General Instruction Building.
