What document records changes in the contract scope of work due to customer requests?

• A. Addendum
• B. Change order
• C. Purchase order
• D. Modification agreement

Answer: (B)

Changing the contract scope after work has started is handled with a change order. This document records exactly what is being added, removed, or altered, along with the updated price and revised schedule. It becomes part of the contract once signed by both parties, providing a clear, enforceable amendment and an audit trail of the agreed change.

An addendum is typically used to add information or clarifications before the contract is signed, a purchase order is used to authorize procurement of goods or services, and a modification agreement can exist in some contexts but is not the standard term for recording post-signing scope changes in construction contracts.
