What document should be used when a change order is necessary in a design-build scenario?

In a design-build scenario, a Request for Equitable Adjustment (REA) is the appropriate document to use when a change order becomes necessary. An REA is specifically designed to address changes in the scope of work or unforeseen circumstances that impact the project, allowing for adjustments in contract terms, including costs and time extensions.

This document provides a formal request for compensation or contract modifications that arise due to changes initiated by the owner or characteristics that were not anticipated in the original contract. It includes details on the reasons for the adjustments and justifications for the additional costs or time needed to complete the project, which is essential for maintaining a clear and documented communication channel between the parties involved.

In contrast, other options may serve different purposes. Change Order Requests, while pertinent, are often less formal and generally outline a proposed change rather than the basis for seeking adjustments. A Performance Bond is a guarantee from surety to complete the project but is not related to the change process itself. A Contract Modification Agreement can document changes but is usually utilized after the terms have been agreed upon, while an REA serves as a request prior to reaching an agreement. Therefore, the REA plays a crucial role in ensuring that necessary adjustments are formally acknowledged and processed.
