What is the contractor required to do when a unilateral change is properly issued under the Changes clause?

When a unilateral change is properly issued under the Changes clause, the contractor is required to continue performance of the contract as changed. This requirement stems from the principle that a change order issued by the contracting officer is considered a lawful directive, and the contractor must comply with it regardless of any disputes that may arise regarding the new terms.

The Changes clause allows the contracting officer to unilaterally make changes to the contract, which can include alterations in specifications, delivery schedules, or other terms. Once this change is officially communicated and documented, the contractor is obligated to proceed with the adjusted work. Continuing performance ensures that project timelines are maintained and that the government’s needs are met.

This approach also aligns with the objectives of contract management, where parties are encouraged to minimize disruptions and maintain the flow of work despite the adjustments made via changes. By proceeding with the changes, the contractor can later seek adjustments to compensation or other contract terms in accordance with the contract's dispute resolution processes, rather than pausing or halting work. This structure facilitates a more efficient and effective contract administration process.
