Who must sign a Construction Change Directive?

A Construction Change Directive is a written order prepared by the architect instructing the contractor to proceed with a change in the work without requiring the prior consent of the contractor. This directive may be issued due to unforeseen circumstances or changes in project specifications.

The necessity for the signature of both the Owner and the Architect/Engineer is essential because the Owner is ultimately responsible for funding the project and must approve changes that impact the budget or scope. The Architect/Engineer’s signature indicates their agreement that the change is necessary and justifiable from a design perspective, ensuring coherence with the overall project intent.

In contrast, while the Contractor does execute the work, their signature is not required on a Construction Change Directive since this document is not a mutual agreement but rather an order to proceed. Therefore, the requirement for the signatures of the Owner and Architect/Engineer reflects their respective roles in validating and authorizing changes to the construction process. This is why the answer highlighting the need for both signatures is the correct choice.
