Paragraph c of Clause 4-1: General Terms and Conditions (March 2006) and Clause B-37: Changes (Construction) (March 2006) allow the CO to make unilateral changes, as specified in the clause, within the general scope of the contract. These changes are accomplished by issuing written change orders. The supplier must continue performing under the contract as changed, except under contracts that are not fixed-price or incrementally funded where the supplier is not obligated to continue or incur costs beyond the limits established in Clause 2-31: Limitation of Cost (March 2006), or Clause B-32: Differing Site Conditions (March 2006). The Postal Service uses the established accounting procedures when analyzing the price or cost of changed work.
