About this file
This is an architectural drawing showing typical roof details for the Armed Forces Retirement Home Sheridan Building renovation project in Washington DC. The drawing (A560) includes nine detailed technical illustrations of various roofing components and assemblies, including roof drains, pipe penetrations, expansion joints, and parapet connections.
The details specify construction requirements such as 3-ply modified bitumen roofing, minimum R-26 rigid insulation with 1/4" per foot slope to drains, air and vapor barriers, and 2-hour fire-rated pre-compressed foam joints (EMSEAL DFR2). The drawing provides specific assembly requirements for standing seam metal roofing, green roof drainage systems, and roof anchor installations. Construction materials include pressure-treated wood blocking, metal flashings, gypsum board, and waterproofing membranes. The drawing was prepared by AE Works for construction bid documents dated November 13, 2024, with a bid addendum issued February 12, 2025.
