About this file
This is an architectural drawing for a roof replacement project at the Chalmers P. Wylie Veterans Outpatient Clinic in Columbus, Ohio, under the U.S. Department of Veterans Affairs. The drawing is an Enlarged Roof Plan for Roof 1D and was issued as part of the Bid Documents dated 05/06/2025, with Addendum 01 issued on 04/27/2026.
The scope of work includes removal of the existing roof system down to the substrate and installation of a new roofing system to match existing conditions, along with waterproofing and paver roof system installation. The project maintains several existing roof penetrations and equipment, including roof drains, overflow drains, pipe vents, lightning protection grounding terminals, anchor posts, radio frequency equipment (which requires relocation and restoration to original location), and electrical conduit penetrations. The drawing legend identifies areas designated for selective removal, fluid-applied rehabilitation, replacement scope work, and areas not in scope. The plan indicates the roof access point, biohazard exhaust area, and high-powered radio frequency area. The document references Architect/Engineer of Record stamp requirements and includes matchlines for coordination with adjacent architectural sheets (AE101, AE102, AE103, and AE141).
