What is the primary responsibility of a contractor when a unilateral change is issued under the Changes clause?

The primary responsibility of a contractor when a unilateral change is issued under the Changes clause is to continue performance as changed. This requirement stems from the nature of unilateral changes, which allow a contracting officer to modify the terms of a contract without the contractor's consent, often in situations where quick adjustments are necessary for the progress of work.

In this context, the contractor is expected to adapt to the changes while still fulfilling their obligations under the contract. This expectation ensures that project continuity and timely completion are maintained despite modifications. If there are any impacts on costs or timeframes as a result of these changes, the contractor can seek appropriate adjustments through a request for equitable adjustment or other contractual remedies.

While options related to ceasing performance or requesting negotiations may seem relevant, they do not align with the fundamental principle that the contractor must complete the work under the modified terms dictated by the contracting officer. Additionally, while concerns about cost limits exist within the contract management framework, these considerations do not absolve the contractor from the immediate obligation to continue performance following a unilateral change.
