What are modifications to the construction plans during the building phase referred to?

Modifications to the construction plans during the building phase are referred to as revisions or change orders because they officially document any changes made to the original plans after construction has begun. These modifications can arise due to various reasons, such as design changes, errors found in the initial plans, or requests from clients for alterations. Change orders serve as a formal agreement between the parties involved, detailing the nature of the changes, the reasons for them, and any associated costs or impacts on the project timeline.

The importance of using the term "revisions or change orders" lies in its legal and procedural implications. It typically requires careful documentation and approval to ensure all parties are aware of the alterations and that the adjustments are communicated effectively. This helps avoid any misunderstandings that might arise later in the construction process, maintaining the project's integrity and accountability.

While terms like corrections, updates, and annotations may refer to minor adjustments or notes on plans, they do not encompass the full scope of formal changes that revisions or change orders imply, making them less suitable for describing modifications that alter the course of the construction progress.
