Central Contracts Unit (CCU)

Please Note: Information and registration for all future training opportunities will now be posted on the Procurement Training page

The Office of the State Controller receives its authority over contracts pursuant to CRS §24-30-202, which, amongst other things, sets forth certain disbursement, contract and payment requirements, the requirement that expenditure contracts be approved by the State Controller or his delegate to be valid and the State Controller’s authority to create Fiscal Rules to carry out his duties. Obligations that violate the Controller’s statute are not binding against the State and any person involved in ordering/incurring the obligation can be held jointly and severally liable for it.

The CCU works with all Central Approvers (State Purchasing Office, Human Resources, Attorney General’s Office, Office of the State Architect, Risk Management and Office of Information Technology) to ensure that contracts comply with all laws, rules and regulations.

Agency Assignments

1525 Sherman Street, 3rd Floor
Denver, CO 80203
Please note: Because the 3rd floor is restricted, access can only be gained by arrangement with CCU staff prior to arriving or by calling a CCU number posted at the door on the 3rd floor.

​Contract Drop Off/Pick Up
Drop Off: Agencies may hand-deliver contracts between the hours of 8:00 am and 5:00 pm Monday through Friday (except State holidays) by depositing them in the CCU's "Contract Drop Off Box" located on the 1st floor of 1525 Sherman Street, Room 102. If the front doors to the left of the entrance are locked, proceed towards the elevators and turn left. The door at the end of the hall is open and leads directly to the Drop Off Box. If your package is too large for the box, go to the 3rd floor and contact CCU staff to hand deliver the package.

Pick Up: The CCU prefers that contracts be returned to agencies via interagency mail. Please include a completed return interagency form (or, if using a different carrier, a prepaid label) with each contract. 

In Person: If an agency does not include a return interagency form or other prepaid label with the contract, that contract will be held for pick up. You may pick up your contract by coming to the 3rd floor of 1525 Sherman Street and contacting CCU staff.
