Change Orders require which of the following for validity?

Change Orders must be validly executed to ensure that all parties involved in the contract are in agreement regarding changes to the scope of work, adjustments in contract price, and extensions to time. For a Change Order to be considered valid, it typically requires the signatures of the Owner, Contractor, and Architect or Engineer. This involvement of all three parties is crucial because:

1. Owner's Interest: The Owner has a vested interest in the project and needs to consent to any changes that may affect the outcome, budget, or timeline of their project.

2. Contractor Accountability: The Contractor must also agree to the Change Order since it may impact their work schedule, resource allocation, or costs. Their signature indicates acceptance of the new terms.

3. Architect/Engineer Oversight: The involvement of the Architect or Engineer is vital as they ensure that the changes align with design intentions and project specifications. Their signature serves as an endorsement that the proposed changes are acceptable from a design and technical viewpoint.

This comprehensive agreement not only helps maintain clarity among all parties but also provides legal protection against disputes that may arise from unapproved changes.
