Change Order Agreement for Heavy Civil Construction

Heavy and Civil Engineering Construction · NAICS 237 · Change Order Agreement

In heavy civil construction, change orders are inevitable. Whether it's an owner-directed design change, an unforeseen utility conflict, or a differing site condition that throws your earthwork quantities off, a clear change order agreement protects your right to additional compensation and time. This document formalizes the change, captures the agreed price and schedule impact, and prevents disputes down the road. It's tailored for projects like highways, bridges, water treatment plants, and site development, where every change can have a ripple effect on equipment, crews, and subcontractors.

Frequently asked questions

What if the owner won't sign a change order but directs the work anyway?

You should still document the directive in writing and proceed under protest if necessary. This change order template can be used to memorialize the directive and your claim for additional costs, even if the owner delays signing.

Can I use this for a federal or DOT project?

Yes, but you must ensure it complies with the specific contract's changes clause and applicable regulations. This template provides a solid starting point, but you should have your contract administrator review it against the prime contract requirements.

What if the change order reduces the scope?

The template allows for a negative adjustment. You can deduct the value of deleted work, and the change order will document the deduction and any schedule relief.
