Change Order Agreement for Construction of Buildings

Construction of Buildings · NAICS 236 · Change Order Agreement

In building construction, changes are inevitable—whether it's a homeowner deciding to move a wall, an architect revising a detail, or an unexpected foundation issue. Without a formal change order, these adjustments can lead to disputes over cost, schedule, and scope. This Change Order Agreement provides a clear, written record of any modification to the original construction contract. It documents the exact change, the reason behind it, the cost adjustment, and the impact on the project schedule. By using this agreement, both contractors and owners can ensure that all parties are aligned, minimizing misunderstandings and protecting their interests. This template is tailored for construction of buildings, including residential, commercial, and institutional projects.

Frequently asked questions

What is a change order and why is it important in building construction?

A change order is a written amendment to the original construction contract that documents any change in scope, cost, or schedule. It is crucial because it prevents misunderstandings and provides legal protection for both the contractor and owner by clearly defining the modification and its impact.

Can I use this agreement for any type of building project?

Yes, this agreement is versatile enough for residential, commercial, or institutional building projects. It is designed to align with standard construction industry practices and can be adapted to fit your specific project needs.

What should I do if the owner refuses to sign a change order?

If the owner refuses to sign, you should stop any work related to the change and document the situation in writing. Proceeding without a signed change order can lead to non-payment and legal disputes. Consult with a construction attorney if needed.
