D.C. Mun. Regs. tit. 19, r. 19-310
This section shall govern all disputes arising under or related to contracts awarded by the Authority to procure goods, services or construction.
In order to make a claim under a contract, a party to the contract shall submit to the CCO a written assertion that the party is entitled to the payment of money in a sum certain, the adjustment or interpretation of a contract provision, or other relief under the contract.
If a claim on behalf of a contractor has a value of more than $ 50,000, the claim shall be accompanied by the certification of the contractor that the claim is made in good faith and that the amount or adjustment requested and the supporting data are accurate and complete to the best of the contractor's knowledge and belief.
The CCO shall attempt to resolve all contractual disputes by mutual agreement after informal discussion. The CCO may agree to the use of alternative dispute resolution procedures, in accordance with the principles governing procurements by the Federal government set forth in relevant sections of Title 48 Code of Federal Regulations at any time that the CCO has authority to resolve the issue in controversy.
If the CCO cannot resolve a claim after informal discussion, the CCO shall, within 60 days of receipt of the claim, issue a written decision granting or denying the claim, giving the CCO's reasoning, and setting forth the contractor's appeal rights. The CCO's failure to issue a decision within this time shall be deemed to be a denial of the claim for the purpose of appealing the Authority's final decision to the District of Columbia Contract Appeals Board.
The District of Columbia Contract Appeals Board shall have exclusive jurisdiction to review final action of the Authority on any dispute.
