§43.103. Types of contract modifications.
48 C.F.R. § 43.103
Contract modifications are of the following types:
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—
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.
Unilateral. A unilateral modification is a contract 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.
