If the contracting officer and the contractor agree in advance to an equitable adjustment in the contract price, delivery terms, or other contract terms, the contracting officer shall issue a bilateral contract modification and shall not be required to issue a change order.
The contracting officer shall negotiate an equitable adjustment resulting from a change order in the shortest practicable time.
Failure to agree to any adjustment shall be a dispute under the disputes clause in the contract and shall be resolved in accordance with the procedures set forth in the Procurement Practices Reform Act of 2010, effective April 8, 2011 (D.C. Law 18-371; D.C. Official Code §§ 2-351.01, et seq.) (2011 Repl.) and Chapter 38 of this title. However, nothing in this section shall excuse the contractor from proceeding with the contract as changed, except as provided otherwise in § 3603.5.
