What are "change orders" in construction projects?

Change orders are formal amendments to the original contract that specifically alter the scope of work agreed upon between the contractor and the client. They can arise for various reasons, such as unforeseen circumstances, design changes requested by the client, or necessary alterations to comply with regulations or codes. By including these changes in the contract, both parties can clearly outline new tasks, adjustments in costs, or modifications to the project timeline resulting from those changes.

Recognizing the significance of change orders is crucial for maintaining clear communication and ensuring that all parties are aligned on project expectations and deliverables. They provide a documented basis for any new work required beyond the initial agreement, helping to prevent disputes and misunderstandings.

The other options mentioned are related to construction management but do not define change orders in the correct context. Requests for payment changes, adjustments in project timelines, and notifications of project delays might occur during a project but do not encapsulate the purpose and definition of a change order, which is explicitly linked to modifying the original contract terms regarding the scope of work.
