About this file
This document is an architectural drawing set for a roof replacement project at the Chalmers P. Wylie Veterans Outpatient Clinic in Columbus, Ohio, operated by the U.S. Department of Veterans Affairs. The drawing, dated April 27, 2026 with bid documents released May 6, 2025, provides detailed specifications for the roof restoration work on Building 1A.
The project scope includes selective removal of the existing roofing system down to the structural deck and installation of a new roofing system to match existing conditions, along with application of fluid-applied waterproofing and paver roof systems in designated areas. Key existing elements to remain include roof drains, overflow drains, HVAC equipment, and air handling units. Work includes removal of existing roof walkway pads with installation of new walkway systems. The drawing identifies multiple roof sections (Roof 1A, 1D, 3A, and others) with specific attention to biohazardous exhaust areas, high-powered radio frequency areas, roof access points, pipe vents, electrical grounding, anchor points, and boot flashing. One addendum has been issued as of the drawing date. The enlarged roof plan and three-dimensional building perspectives provide comprehensive visualization of the restoration scope across the facility's multiple roof sections.
