About NIGP 77093
NIGP 77093 Waterproofing Membrane and Base Sheet, an Item code, encompasses removal and installation of single-ply membranes (TPO, EPDM, modified bitumen) and associated substrate systems at municipal, county, school district, and special-purpose facilities. State and local governments procure this work through RFP, RFQ, IFB, and ITB notices as discrete roofing and building-envelope components within larger capital projects, with recent solicitations emphasizing manufacturer certification, multi-year warranties, prevailing-wage compliance, and bonding requirements. Issuing bodies include city procurement offices (Tallahassee, Taylor, Rome, College Park, Tybee Island), county departments (Chatham, Santa Clara, Jefferson, Marion, Solano, Harris), school districts (Hillsborough County, San Jacinto College, Stephens County Board of Education, DeKalb County), transit authorities, and tribal governments. The work sits at the intersection of roofing and waterproofing, with scope commonly involving substrate inspection and repair, insulation installation, flashing and trim, surface preparation per SSPC or manufacturer standards, and labor coordination with facility closures or operational constraints.
Recent activity concentrates in Georgia (Brooks County, Chatham County, College Park, Tybee Island, Stephens County, DeKalb County), California (Santa Clara County, San Jacinto College, Eugene/Oregon), Texas (Harris County, Jefferson County), Florida (Hillsborough County, Marion County), and Michigan (Taylor). Representative recent opportunities include Brooks County, Georgia's Armstrong Campus re-roof with TPO installation (ITB/RFP due November 17, 2026); Chatham County's 40,800-square-foot Records Center TPO membrane installation with 30 percent M/WBE participation goal and June 18, 2026 deadline; Harris County Precinct 2's Leonel J. Castillo Community Center TPO replacement (ITB due June 15, 2026) requiring five-year workmanship and 20-year manufacturer warranty; and Hillsborough County Public Schools' waterproofing services RFP (26284-MST, due August 17, 2026) with 10 percent small-business-enterprise weighting. Contracts range from under $100,000 site-specific repairs to multi-million-dollar campus-wide envelope projects; prevailing-wage requirements, M/WBE participation goals, and FEMA compliance appear in jurisdictions with federal funding or state prevailing-wage laws. Bonding—bid bonds ranging 5–10 percent and performance/payment bonds at 100 percent of contract value—is standard for projects above $50,000.
