UNSPSC 73151701: Water proofing material treatment services

UNSPSC 73151701 Water proofing material treatment services is a Commodity code that covers roof restoration, waterproofing, and membrane treatment work on existing buildings, including silicone recoating, EPDM repair, PVC membrane installation, elastomeric coating systems, and related sealant and flashing work. State and local governments procure these services to address water intrusion, extend roof life, and restore watertightness on municipal and institutional facilities including libraries, courthouses, cultural centers, water utilities, educational institutions, and county maintenance buildings. Issuing bodies span city planning and public works departments, county governments, university systems, school districts, water authorities, and community college districts. The work commonly appears in competitive sealed bids (IFB) or requests for proposals (RFP) structures with response deadlines ranging from two to eight weeks. Representative recent opportunities include the City of Tallahassee issuing IFB 08126KM for waterproofing at the Senior Center with bids due July 9, 2026; the City of St. Marys, Georgia soliciting proposals for roof recoating on City Hall (approximately 90,440 square feet, due March 26, 2026); the Macon Water Authority procuring roof restoration at Rocky Creek Water Reclamation Facility's Maintenance Building with sealed bids due May 12, 2026; and Mt. San Antonio Community College District seeking registered waterproofing consultants for on-call professional services under RFQ 2026-019 covering site analysis, envelope inspections, design, and warranty verification through October 2030.

Geographic activity concentrates in Georgia (Macon, Atlanta, St. Marys, Tybee Island, Glynn County, Walker County, Cobb County, DeKalb County, Butts County), with secondary activity in Florida (Seminole County, Tallahassee), Texas (Houston, Dallas), Connecticut, California, Colorado, Oregon, and South Carolina. Most solicitations are competitively bid with award to the lowest responsible and responsive bidder; insurance requirements typically mandate Commercial General Liability of $1,000,000 to $2,000,000 per occurrence, workers' compensation at statutory limits, and performance/payment bonds at 100 percent of contract value when awards exceed $25,000 to $100,000 thresholds. Warranty periods commonly extend 20 years from manufacturer and 2 to 3 years from installer. No set-aside designations for disadvantaged enterprises appear in recent solicitations, though several issuers note openness to DBE, MBE, and WBE participation. Work schedules typically compress to 30–180 days, with liquidated damages assessed at $300 to $2,000 per day for delays, and retainage held at 5 to 10 percent pending completion and acceptance.
