UNSPSC 71101606: Underground seal installation service

Service that installs underground wall seals to block off old mined areas or move fresh air to specific areas of mine. Seals are built to MSHA standards.

UNSPSC 71101606 Underground seal installation service is a Commodity code that spans underground utility and infrastructure sealing work performed as part of broader construction and utility projects. State and local governments buy underground seal installation services primarily through highway and road construction projects, stormwater and water utility upgrades, and irrigation system work. Issuing bodies include county transportation divisions, municipal public works departments, and state transportation agencies. Broward County Highway Construction and Engineering Division, the City of Fort Worth, the City of DeBary, and the Florida Department of Transportation District Four have all procured work touching on underground infrastructure sealing and related subsurface activities in the recent solicitation window.

Recent opportunities show activity concentrated in Florida and Texas. The Broward County Pine Island Road Capacity Expansion project (ITB, response due June 2, 2026) encompasses utility upgrades and infrastructure work requiring underground utilities certifications and coordination with water control district dredging and bulkhead construction. The Florida Department of Transportation District Four's Districtwide Storm Sewer Inspection solicitation (ITB 14934, response due February 23, 2026) covers storm sewer system assessment across Broward County with a $500,000 maximum contract value. The City of Fort Worth's Filter Media RFP (response due May 7, 2026) and the City of DeBary's Rob Sullivan Park Irrigation Improvements bid (closed April 10, 2015) represent municipal water and irrigation work in Texas and Florida respectively. These opportunities reflect a pattern of sealing and underground infrastructure work embedded within larger construction and utility procurement initiatives rather than standalone seal installation contracts, indicating that the code captures a subset activity within broader, higher-value project scopes.
