What should a contracting officer do when notified by the contractor of a constructive change?

When notified by a contractor of a constructive change, the contracting officer should first evaluate the claim to determine its validity and the impact on contract performance. They should gather relevant documentation and communicate with the contractor to clarify the circumstances surrounding the change. It’s essential to assess any potential cost or schedule implications and, if warranted, formally acknowledge the constructive change through a written modification or directive. Finally, the contracting officer should ensure that all actions and communications are documented to maintain a clear record of the process.
