A contract or intragovernmental order that contains draft updated or modified information along with the original contract or intragovernmental order information. If applicable, the modification may include an additional funds certification. Modifications include any written change in the terms of a contract or order including bilateral and unilateral modifications. A bilateral modification (supplemental agreement) is a modification that is signed by the contractor and the contracting officer. Bilateral modifications are used to make negotiated equitable adjustments resulting from the issuance of a change order; definitize letter contracts; and reflect other agreements of the parties modifying the terms of contracts. A unilateral modification is a modification that is signed only by the contracting officer. Unilateral modifications are used, for example, to make administrative changes; issue change orders; make changes authorized by clauses other than a changes clause (e.g., Property clause, Options clause, or Suspension of Work clause); and issue termination notices. |
