General Goods and Services

CDOT uses a variety of goods and services for the day-to-day operations of the agency. These are products and services NOT used directly on highway construction or maintenance projects. They call these items Professional Services, Supplies and Commodities. Firms that provide general goods and services are called Vendors. 

Some examples of vendors are janitorial cleaning products and services, office supplies, furniture, equipment, legal assistance, information technology support, construction management, and other equipment and supplies such as the temporary message boards you see along the highway. 

How Does CDOT Buy General Goods and Services?

Purchases for these types of items are managed by the Center for Procurement and Contracting. Goods and services valued at more than $25,000 are solicited through a competitive bidding process. Bids are submitted to CDOT electronically through the CDOT Supplier Self-Service Portal

CDOT also uses standard price agreements to order directly from vendors similar to a catalog purchase. Vendors providing goods and services under the competitive purchase thresholds may be able to contract with CDOT directly by contacting interested buyers in various departments. 


Vendors interested in doing business with CDOT need to register in CDOT's Supplier Self-Service Portal (SuSS) and complete the online prequalification application under the RFx and Auctions section of the site. Follow the instructions for using the portal to help with the registration and submittal process.

Types of Solicitations

CDOT uses several methods to solicit bids depending on the type of good or service.
  • Documented quotes are the most basic in which vendors are asked to simply provide pricing information for the items requested. Award is made to the lowest bidder.
  • Invitation for bid or “IFB” is similar, except that additional information such as qualifications or references may also be requested. Award made to the lowest bidder.
  • 2-Step IFB is used to solicit information from vendors regarding capabilities and price for the solution. Award is made to the most qualified and then lowest bidder of those qualified.
  • Requests for Proposals are more extensive and typically used for services rather than general goods. Award is made to the best solution offered.

Standard Pricing and Cooperative Agreements

When CDOT purchases goods or services, regardless of dollar amount, CDOT first considers State Price Agreements. These are managed by the State Purchasing & Contracts Office and available to all state agencies. These contracts generally do not have a set dollar amount; however, when State agencies need to purchase a commodity or service, they contact the vendor with the agreement. Agreements generally run for a year, with the possibility of renewal for a set period after the initial year is over. The Agreements are published by category and open for bidding annually.

CDOT also manages its own price agreements for goods and services they purchase frequently. These CDOT Price Agreements are very similar to the statewide agreements but are solicited directly by CDOT. CDOT may use Cooperative Agreements managed by the Colorado Multiple Assembly of Procurement Officials. Suppliers may contact invidual agreement managers to understand contract terms and future bid opportunities.  

Where Do You Find Opportunities?

A list of bidding opportunities can be found on CDOT's Procurement and Contract Services web page and also in the CDOT Supplier Self-Service Portal. Many of these solicitations are also posted on the Rocky Mountain ePurchasing system along with other local and  municipal government agencies in Colorado. The system is free to browse but does require an annual subscription fee for enhanced services such as email notification.

DBE/ESB and Veteran Owned Firms

The DBE Program and ESB Program and goals do NOT apply to these types of purchases. If your business primarily provides general goods and services, you may not be eligible for CDOT small business certifications. However, the state of Colorado does have a 3% contracting goal for Service-Disabled Veteran-Owned Small Businesses. Therefore, CDOT and other state agencies actively seek out these firms to supply goods and services.
