See the accompanying photos and floorplan for more detail of the referenced areas. The roof over the main building is the original roof that was constructed circa 1995 and has far surpassed its lifespan. There are multiple soft spots scattered all over the roof with low areas that pool large amounts of water. The problem areas have gone unaddressed for so long that there are even large grassy patches growing out of the roof. The impacted areas have resulted in flooding into many exam rooms, large leaks in the pharmacy, and scattered leaks in office spaces. A storeroom has a leak that pools in the fluorescent lighting causing the room to no longer be useful due to safety issues. Contractor will replace all 29,043 square feet of roof over the main facility. The areas adjacent to the proposed repairs and renovations will be continuously occupied by the OKC VAMC.
