About this file
This is an architectural drawing set for a roof replacement project at the Chalmers P. Wylie Veterans Outpatient Clinic in Columbus, Ohio, managed by the U.S. Department of Veterans Affairs. The project involves the replacement of roofing systems on Building 1A, with work divided into multiple roof sections totaling approximately 4,260 square feet across Roof 7, Roof 14A, and Roof 14B.
The scope includes selective removal of the existing roofing system down to the substrate, application of a new roofing system to match existing specifications, and waterproofing and paver roof systems where applicable. The work requires preservation of existing roof drains, overflow drains, pipe vent penetrations, HVAC equipment, and lightning protection grounding terminals, with inspections and contractor discussion of any discovered issues during removal and installation. The drawing package is dated as Bid Documents from May 6, 2025, with Addendum 01 issued on April 27, 2026. The project is fully sprinklered and designed by FFE and HEAVY consultants, with the Architect/Engineer of Record stamp required. Work areas include biohazardous exhaust areas, roof access points, and high-powered radio frequency areas that must be carefully managed during construction.
