Which of the following should NOT be included in a change order?

A change order is a formal document that outlines changes to the original construction contract, including amendments to costs, scope, or schedule. It serves to ensure all parties are aware and agree to these changes before they are executed.

The inclusion of an engineer's signature in a change order is not typically necessary because the change order is a contractual agreement primarily between the owner and the contractor. While the engineer may be involved in the planning and execution of the project, their signature is not a requirement for the validity of the change order. The essential elements of a change order usually focus on changes related to project timelines, cost estimates for additional work, and detailed material specifications, which are critical for implementation and budgeting.

On the other hand, project timelines are essential for understanding how changes impact the overall schedule, cost estimates are needed for financial adjustments, and a materials list can define specific items affected by the change. All of these elements contribute to a comprehensive understanding of how the change will affect the project's execution and accountability.
