What is a "change order" in construction management?

In construction management, a "change order" is primarily a document that modifies the original scope of work outlined in a construction contract. Change orders are critical because construction projects often encounter unforeseen circumstances that necessitate alterations to the initially agreed-upon plans. This can include changes in design, additional work that needs to be completed, or modifications in the timeline or budget.

When a change order is issued, it serves to formally document the changes and outline any adjustments to costs or schedules stemming from those modifications. This ensures that all parties involved in the project have a clear understanding of the new terms and helps prevent disputes later on regarding what was originally agreed upon versus what is being executed.

The other options, while relevant to the construction process, do not accurately define a change order. For instance, a document verifying the completion of a project would refer to a project completion certificate, while a checklist of required materials relates to procurement and planning. A financial report for project expenses is also an essential document but is separate from the scope of work modifications that a change order entails.
