Which document is used to modify contract scope, time, or cost?

• A. Change Order
• B. RFI
• C. Architect's Supplemental Instructions
• D. Submittal

Answer: (A)

A change order is the formal instrument used to modify contract scope, time, or cost. It records an agreed-upon change to the signed contract—such as adding or removing work, adjusting the project schedule, or altering the contract sum—and becomes part of the contract documents once signed by the involved parties. This creates a clear, legally binding basis for any adjustment to price and timeline and ensures everyone is aligned on the new requirements. Requests for information seek clarification and do not authorize changes to the contract. Architect’s Supplemental Instructions provide clarification or interpretation of the contract documents but do not by themselves modify the agreement. Submittals are items for review and approval of products or methods and do not alter the contract terms.
