General wage determinations
. (1) A general wage determination contains prevailing wage rates for the types of construction designated in the determination, and is used in contracts performed within a specified geographical area. General wage determinations contain no expiration date and remain valid until modified, superseded, or canceled by the Department of Labor. Once incorporated in a contract, a general wage determination normally remains effective for the life of the contract, unless the contracting officer exercises an option to extend the term of the contract (see 22.404-12). These determinations shall be used whenever possible. They are issued at the discretion of the Department of Labor either upon receipt of an agency request or on the Department of Labor's own initiative.
