What does a change order typically involve?

A change order typically involves a formal change in the scope of work that has been agreed upon by all parties involved in a construction contract. This process is essential to ensure that any modifications to the original contract are documented and approved, providing a clear understanding between the contractor, client, and any other stakeholders.

Change orders can arise due to various reasons, such as unforeseen circumstances, design changes, or regulatory requirements that necessitate alterations in the project. By formalizing these changes, all parties can adjust schedules, budgets, and expectations accordingly, which helps maintain transparency and accountability throughout the project.

The other options focus on specific aspects like costs or unilateral changes, which do not encompass the broader, collaborative nature of a change order necessary for maintaining an effective working relationship among all parties involved in a construction project.
