Who must sign a Change Order after a project is awarded?

The correct answer is that the Owner must sign a Change Order after a project is awarded. A Change Order is a formal document issued to modify the original construction contract. It can involve adjustments to the project scope, budget, or time frame, and serves to ensure that all parties agree to the changes being made.

The reason the Owner's signature is essential is that they are the party that ultimately holds the contract with the contractor. By signing the Change Order, the Owner gives authorization for the changes to take place, which is critical for maintaining clear communication and consensus regarding the project. This protects both the Owner's and contractor's interests in the event of any disputes or further negotiations that may arise from the modifications.

Other parties, such as the Engineer, Subcontractor, or Supplier, play roles in the project and may have input or agreement about certain aspects of the Change Order, but it is the Owner’s approval that is legally required for the alteration of the terms of the contract.
