What is required for a contractor to make changes to an existing construction plan?

A written change order approved by relevant parties is essential for making changes to an existing construction plan because it provides a clear and formal record of the modifications agreed upon. This document helps ensure that all parties involved are on the same page regarding the changes, including the scope of work, cost adjustments, and timelines. By securing written approval, the contractor can avoid misunderstandings and potential disputes later in the project.

Using a verbal confirmation or an informal agreement, such as an oral agreement, lacks the necessary documentation that protects the rights and responsibilities of all parties involved. Additionally, relying on a standard form signed by just one party, like the site manager, may not encompass the necessary approvals from all stakeholders required for significant alterations to a construction plan. Thus, a written change order that has been approved by all relevant parties is the industry standard for ensuring that changes are executed smoothly and legally.
