What is a Change Order best defined as?

A Change Order is best defined as a written instrument that modifies the original contract by detailing changes in the Work, which often includes adjustments to the Contract Sum and Contract Time. The necessity for a Change Order typically arises when conditions on-site differ from what was anticipated, requiring modifications to the scope of work, additional materials, or extended timelines.

By framing it this way, the Change Order ensures that all parties have a clear understanding of the changes being made, as well as the ramifications on costs and scheduling. This written documentation is crucial for maintaining transparency and managing expectations within the contractual relationship between the parties involved.

Other options may refer to elements related to change orders, like directives from the Architect/Engineer or alternative methods of compensating for changes, but they do not fully capture the comprehensive definition provided by the correct choice. A Change Order specifically consolidates modifications in a way that has been agreed upon by all relevant parties, making it a formal amendment to the contract instead of just a directive or proposal.
