UNSPSC 81101526 Quantity surveying service, a Commodity code, encompasses independent cost estimation, schedule analysis, risk assessment, and price validation services that state and local governments procure to support infrastructure and construction projects across design, preconstruction, and construction phases. The work ranges from reviewing cost estimates and guaranteed maximum price proposals on design-build and traditional delivery projects to preparing construction plans and performing field surveys that feed cost models. Recent state and local solicitations show this code active across a mix of issuing bodies—state departments of transportation and water resources, county transportation and water utilities departments, transit authorities, and municipal public works offices—with buyers concentrated in Texas, California, Florida, and Georgia seeking both standalone cost estimating support and embedded surveying and estimation work within larger professional services continuing contracts.

California Department of Water Resources' November 2026 procurement for independent cost estimator services on the Kane Spring Habitat Restoration Project (Statement of Qualifications due November 19, 2026, estimated contract value $1 million to $10 million) exemplifies the current scope: evaluation of cost estimates, schedules, and guaranteed maximum price proposals across progressive design-build phases. Texas Military Department's September 2026 request for vegetation community planning surveys at four training center locations (bids due September 26, 2026) and similar survey-and-estimate work under multiple state and regional transit RFQs reflect demand for baseline data collection tied to cost modeling and project feasibility. Broward County Transportation's July 2026 call for Bus Rapid Transit consulting services (proposals due July 17, 2026, total estimated budget $30 million across up to three firms over five years) shows quantity surveying embedded within broader program management and construction oversight contracts. Small firms and subspecialties dominate qualification-based selections; many buyers structure work as on-call or task-order arrangements with no guaranteed minimum volume, creating a fragmented but steady market across counties and special-purpose districts in the Southeast and Southwest.
