43.103 Types of contract modifications.

Contract modifications are of the following types:

      (a) Bilateral. A bilateral modification (supplemental agreement) is a contract modification that is signed by the contractor and the contracting officer. Bilateral modifications are used to-

           (1)Make negotiated equitable adjustments resulting from the issuance of a change order;

           (2)Definitize letter contracts; and

           (3)Reflect other agreements of the parties modifying the terms of contracts.

      (b) Unilateral. A unilateral modification is a contract modification that is signed only by the contracting officer. Unilateral modifications are used, for example, to-

           (1)Make administrative changes;

           (2)Issue change orders;

           (3)Make changes authorized by clauses other than a changes clause (e.g., Property clause, Options clause, or Suspension of Work clause); and

           (4)Issue termination notices.
