Colorado Public Works Bonding Basics
Colorado's public works bonding framework is governed by the Public Works Bond Act in Colorado Revised Statutes §38-26-105 through §38-26-110. It applies to all state, county, municipal, and school district construction.
C.R.S. §38-26-106 Requirements
Colorado requires a performance and payment bond on every public works contract exceeding $50,000. Each bond must equal 50% of the contract price at minimum (combined, often 100%), executed by a surety authorized in Colorado. Most Colorado public owners require 100% performance and 100% payment bonds through their bid specs, regardless of statute minimums.
Federal Projects in Colorado
Federal construction follows Miller Act rules. Colorado federal volume includes Fort Carson, Peterson Space Force Base, Schriever Space Force Base, the U.S. Air Force Academy, Buckley Space Force Base, NORAD facilities at Cheyenne Mountain, VA Medical Center Rocky Mountain Regional, Rocky Mountain National Park, and extensive Department of Energy work at facilities like Rocky Flats cleanup.
Payment Bond Claims Under §38-26-107
Subcontractors, material suppliers, and laborers must file written notice of claim to the contractor and surety within 90 days of last furnishing. Suit must be filed within 6 months after the contractor's final settlement with the owner, or within 1 year of last work if final settlement doesn't happen. The dual-deadline structure catches sub-tier contractors who aren't tracking the prime's owner settlement.
Who Counts as a Public Entity in Colorado
§38-26 covers the State of Colorado, all 64 counties, every home-rule and statutory municipality, school districts, special districts (metro, water, fire, sanitation), and public authorities. Colorado's special district ecosystem is extensive — Denver Metro, RTD, Regional Parks, and countless water/sanitation districts.
Colorado Denver Metro Construction Boom
The Denver metro area has been among the fastest-growing US construction markets for the past decade. RTD transit expansion, DIA expansion, I-70 rebuild, and constant residential/commercial development generate heavy public works bonding demand. This creates real opportunity for qualified contractors.
Bid Bonds in Colorado
CDOT requires bid bonds of 5% on virtually all state transportation projects. Denver, Aurora, Colorado Springs, and other major cities require bid bonds on most public projects. School districts (DPS, JeffCo, Cherry Creek, Douglas County) require bid bonds on bond-measure-funded construction.
Colorado Mountain & Western Slope Specifics
Public works on Colorado's Western Slope and in mountain counties involves altitude, weather, and logistical challenges that surety underwriters account for. Limited construction season, remote locations, and specialty equipment needs affect both capacity evaluation and bonding pricing. Experienced mountain contractors build track records that standard valley contractors don't.
Qualifying for Colorado Public Works Bonding
Standard criteria apply. Colorado-specific notes:
- Understand the altitude and season constraints if bidding mountain work
- Work with a surety agent who knows Colorado's special-district ecosystem
- Keep CPA-prepared financials current; Colorado underwriters are fairly standard nationally
- Build track record with smaller metro or county contracts
