About Colorado government procurement

Colorado state procurement is centralized through the Colorado Department of Personnel & Administration (DPA) State Purchasing Office and runs on Vendor Self Service (VSS) at colorado.gov/vss, a Bonfire-adjacent platform. All executive-agency solicitations flow through VSS. Colorado awarded approximately $8 billion in commodities, IT, professional services, and construction contracts in FY24 across state agencies plus the University of Colorado System (Boulder, Denver, Colorado Springs, plus UCHealth), Colorado State University System, and the Colorado Community College System (13 colleges).

The Colorado Department of Transportation (CDOT) is the largest state buyer, running approximately $1.5 billion in annual highway, bridge, and multimodal construction lettings through the CDOT Bidding System. Bidders must complete CDOT Contractor Prequalification for financial capacity, past performance, and equipment. Federal-aid projects carry Davis-Bacon wages, Buy America iron/steel, and DBE subcontracting goals typically 10-12%. CDOT also runs the P3 program (US 36 Managed Lanes, I-25 South Gap) and the Bustang intercity bus procurement program.

Colorado's Small Business Reserve targets Colorado-based small businesses on contracts under $250,000 — a bidding preference plus a set-aside for select categories. Colorado Emerging Small Business (ESB) certification is a subset for microbusinesses under specific size thresholds. Certification is through the DPA State Purchasing Office. Colorado prevailing wages under the Public Works Contract Law apply to state and local public works over $500,000 and are enforced by the Department of Labor and Employment. Federal Davis-Bacon still applies on federal-aid work.

Local procurement runs on many platforms. Denver uses DenverBids at denvergov.org/finance/purchasing. Colorado Springs uses ColoSprings Bids. Denver County (city-county), Jefferson County, Arapahoe County, Adams County, and Boulder County each run separate procurement systems. Colorado's 64 counties and 271 municipalities each publish RFPs independently. School districts across 178 Colorado school districts each publish RFPs independently — Denver Public Schools, Jefferson County Public Schools, Cherry Creek Schools, and Douglas County School District are among the largest. Emerging demand: Colorado clean-energy transition under the Colorado Clean Air Act, hydrogen infrastructure at NREL/Golden, plus wildfire mitigation grants at the Colorado State Forest Service.

Largest Colorado state buyers

The largest Colorado state buyers are the Colorado Department of Transportation (CDOT — $1.5B+ annual lettings), Department of Personnel & Administration (DPA commodities and IT), Department of Corrections, Department of Health Care Policy & Financing (Medicaid), Department of Human Services, Department of Public Health and Environment, University of Colorado System (Boulder, Denver, Colorado Springs, plus UCHealth), Colorado State University System, Department of Natural Resources, and Department of Public Safety. Denver (city-county), Colorado Springs, Jefferson County, Arapahoe County, Adams County, and Boulder County are the largest local buyers. Denver Public Schools, Jefferson County Public Schools, and Cherry Creek Schools are major school-district buyers. Regional Transportation District (RTD Denver) is a heavy federal-aid transit buyer.
