How We Buy

Purchases of goods and personal services (janitorial and office supplies, heavy tow service, variable message signs, parts, and maintenance, etc.) must comply with the Procurement Code in the Colorado Revised Statutes (C.R.S.) and Procurement Rules. Certain professional services such as; architecture, engineering, professional land surveying, landscape architecture, industrial hygiene (C.R.S. 24-101-105, C.R.S. 24-30-1402)  are excluded from the Procurement Code.  Some services are procured through both CDOT's Center for Procurement Contract Services and Engineering Contracts (highway and bridge construction).  Visit Connec2DOT's website to see an example of how certain items are purchased.

CDOT strongly encourages the utilization of small businesses, including businesses owned by minorities, women, and veterans when purchasing goods and services with lower dollar values (discretionary purchases).  Procurement seeks to provide all businesses regardless of size or ownership opportunity to compete for CDOT contracts.

Disadvantaged Business Enterprise (DBE) and Emerging Small Business (ESB) certifications are recognized in bridge and highway construction and generally are not considered in procurement. Contact the Civil Rights Office for more information on these certifications.

The Procurement Code sets a goal for Colorado-based Service-Disabled Veteran-Owned Small Businesses (SDVOSB) certified through the U.S. Department of Veterans Affairs.   

Suppliers wanting to business with CDOT can review each tab below to understand how CDOT buys goods and services, and learn about various resources available.

When goods or services are needed, regardless of dollar amount, CDOT first considers State Price Agreements (managed by the State Purchasing & Contracts Office) and other cooperative agreements (CDOT Cooperative Purchasing Agreements, The Governors' Office of Information Technology Enterprise Agreements, MAPO Cooperative Agreements).  Suppliers may contact the managers of agreements to understand contract terms and future bid opportunities. 

The decision or choice of supplier for discretionary purchases (goods and services less than $25,000) is primarily through CDOT employees who end users of goods, materials, and equipment, and/or the program managers responsible for the goods or services being purchased.  

It can be challenging to find who these individuals are within CDOT, and a variety of marketing and networking approaches may be needed to make your business known to the right buyers.  Consider attending the Day at the DOT to meet potential customers.    

When no cooperative agreements are available, and when the anticipated cost is greater than $25,000 for goods or services, CDOT publishes competitive bids.  

All goods and services bids are published on BidNet Direct's Rocky Mountain E-Purchasing site.  CDOT only accepts electronic bid submissions on this site.  Suppliers interested in submitting bid responses must register in a timely manner to ensure their bid is responsive.   

Bid history or bid results can be found on our Bid Log.  Bid tabulations are linked to the RFx number on the spreadsheet.  View bid status on BidNet Direct for our most recent bids.  Contact the Purchasing Agent listed for more information regarding a specific procurement.
