UNSPSC 81101507: Dam engineering

UNSPSC 81101507 Dam engineering, a Commodity code, covers independent cost estimation, structural assessment, and engineering design and permitting services for dam rehabilitation, repair, and alternatives analysis work that state and local water authorities, counties, and municipalities are procuring. Recent opportunities show state and local governments acquiring specialized advisory services—independent cost estimator support for P3 and alternative-delivery infrastructure projects, structural concrete repair coordination, comprehensive hydrologic and hydraulic assessments, and full-cycle engineering design from preliminary engineering reports through construction administration for high-hazard and significant-hazard dams.

The code sees sustained activity across the Southeast and West, with Georgia Department of Transportation and river authorities leading the recent volume. Georgia DOT has posted multiple RFQs for independent cost estimating and general engineering consulting services supporting alternative delivery and P3 projects including the I-285 East Express Lanes and I-75 South Express Lanes, with responses due November 16, 2026 and August 24, 2026 respectively; Fayette County, Georgia issued an ITB for structural concrete repairs to Lake McIntosh Dam spillway (due November 19, 2026); and the Brazos River Authority in Texas released RFPs for hydrostatic pressure relief system assessment and downstream channel improvements at Sterling C. Robertson Dam (proposals due October 14, 2026) and for Lake Limestone HPRS assessment (due August 14, 2026). The Utah Division of Wildlife Resources solicited statements of qualifications for Zeedyk-style in-stream structure design and implementation on Goslin Creek (due October 19, 2026). Connecticut and Colorado Parks and Wildlife have procured design, engineering, and construction management services for Paper Goods Pond Dam and Spring Creek Dam rehabilitation respectively. Colorado also procured CMGC preconstruction services for Spring Creek Dam (proposals due June 15, 2026). The Barberville Dam alternatives analysis for Rhode Island DEM is structured as a qualification-based selection with 18-month performance (qualifications due July 21, 2026). Geographic concentration runs heaviest in Georgia, with secondary activity in Texas, Colorado, Rhode Island, Connecticut, and Utah reflecting ongoing high-hazard dam rehabilitation programs and alternative-delivery infrastructure development.
