Which document is issued by a principal directing changes in a contract authorized under the contract's changes clause?

• A. Non-conformance Report
• B. Site Instruction Notice
• C. Contract Change Notification (CCN)
• D. Change Control Board (CCB)

Answer: (B)

When the owner needs to direct a modification to the work under the contract’s changes clause, the instrument used is a Site Instruction. This document comes from the principal (or their on-site representative) and provides explicit directions to alter, clarify, or add to the work so the project can proceed. It serves as a quick, on-site directive to implement needed changes, with any resulting impact on cost or schedule addressed later through the contract’s formal change processes. A Non-conformance Report records defects and required corrective action, not a directive to change the contract. A Contract Change Notification is a formal notice that a change is being proposed or has occurred, and a Change Control Board is the group that reviews and approves changes, not a specific on-site directive.
