What best describes the role of change orders in construction?

The role of change orders in construction is primarily to formally document any changes in project scope or details. Change orders serve as official amendments to the original construction contract, ensuring that any modifications—whether they involve additional work, alterations in project specifications, or adjustments to timelines—are recorded in a clear and legally binding manner. This formal documentation is essential, as it protects both the contractor and the client by outlining the agreed-upon changes and any associated adjustments in costs or project timelines. By having a formal record of these changes, it helps to prevent misunderstandings and disputes down the line, ensuring that all parties are on the same page regarding what has been altered from the original agreement.

The other options, while touching on aspects related to change orders, do not capture their primary function as accurately as the correct answer. For instance, although change orders can have pricing implications, their main purpose is not to allow greater flexibility in pricing but to outline changes in scope. Similarly, change orders do not eliminate the need for contracts; rather, they modify existing contracts. Finally, while improved communication among workers can be a benefit of having clear change orders, the core function of change orders lies in their role as formal documentation of changes.
