Specifications include, but are not limited to: The purpose of this Request for Proposals is to engage the services of a professional engineering firm to provide the services necessary to upgrade the roofing system at the Safety Center described below. The Apparatus Bay roof is a 45 mil EPDM ballasted type with tapered insulation that is approximately 25 years old. The office area of the Safety Center is a 24-gage standing seam metal roof system that is approximately 25 years old. The lower-level office metal roofs experience water infiltration during driving wind/rain events and the apparatus bay area roof experiences leaks due to age, ponding, and drainage issues. Exterior walls become saturated during rain events due to the lack of gutters and proper water mitigation control. The purpose of this work is to review the roofing systems, develop details and specifications for new roofing systems, and design improvements to direct water away from the building.
