UNSPSC 72141123: Manhole construction service

The building of manhole access stations owned by others

UNSPSC 72141123 Manhole construction service is a Commodity code capturing specialized underground infrastructure installation work that state and local governments buy to replace, repair, and rehabilitate sanitary sewer, storm drain, and combined sewer systems. Recent solicitations show manhole work embedded within larger sewer rehabilitation, storm drain improvement, and gravity main replacement projects across municipalities, counties, water authorities, and utility commissions. The work typically combines manhole installation with pipe replacement, cured-in-place lining, lateral reconnections, and site restoration. Issuing bodies span cities, counties, regional water and sewer authorities, and utility districts; repeat buyers include multiple Mississippi municipalities (Brandon, Flowood, Pope, Leakesville, Ruleville), Georgia cities and authorities (Americus, Berkeley Lake, Tennille, Warner Robins, Chamblee), Florida counties and municipalities (Seminole County, Collier County, Orange County, Flagler County), and the City of Waco, Texas. Geographic concentration appears strongest in the Southeast — particularly Georgia, Florida, and Mississippi — with secondary activity in the Mid-Atlantic (Virginia, North Carolina) and Texas.

Representative recent opportunities include the City of Brandon, Mississippi's Highway 18 Sewer Extension Phase 1 (ITB, bids due July 24, 2026), soliciting installation of approximately 2,000 linear feet of 15-inch gravity sewer with associated manholes and appurtenances; the Douglasville-Douglas County Water and Sewer Authority's Donny Brook Lane Stormwater Improvement (IFB 322, bids due August 5, 2026), calling for removal of 71 linear feet of 54-inch corrugated metal pipe and installation of a new concrete box culvert with two new concrete headwalls; Seminole County, Florida's Gravity Sewer Improvements on Talbot Road, Kewannee Trail, and Hollyridge Road (IFB CC-6816-26/TAD, bid deadline February 18, 2026 with engineer's estimate $3.24 million), encompassing approximately one mile of gravity sanitary sewer with 11 new precast concrete manholes; and the City of Waco's Speegleville Road Lift Station Improvements (RFB 2026-025, bids due August 12, 2026 with engineering estimate $1.5 million), covering lift station rehabilitation, piping, valve installation, and electrical systems. Manhole work in this market segment typically appears as unit-price or lump-sum line items within larger IFB and RFB procurements, with bid bonds of 5–10 percent, performance and payment bonds at 100 percent of contract value, and substantial completion periods ranging from 60 to 335 calendar days depending on scope complexity and site constraints.
