What is defined as a change order in construction?

A change order in construction is defined as a formal document that alters the original contract. This definition is crucial because a change order typically arises when modifications to the project scope, timeline, or budget are necessary during the construction process. This could include any changes such as additions to the work, variations in specifications, or adjustments due to unforeseen circumstances.

By formally documenting these changes, a change order ensures that all parties involved—the contractor, client, and any relevant stakeholders—are in agreement about the new terms. This helps maintain clarity and accountability, preventing disputes and misunderstandings. The existence of a formal change order also serves as a legal record, providing evidence of the agreed-upon changes to the contract.

In contrast, the other options do not adequately capture this formalized process. A request for additional work without a cost adjustment may not involve contractual changes at all. An estimate of the total project costs is simply a prediction and does not alter any contract terms. Lastly, a notice of delay in project completion relates specifically to scheduling rather than changes to the scope or financial terms of the contract.
