Construction change order template

A change order form records what changed, what it costs, how it moves the schedule, and who approved it. Download this template as a CSV for Excel or Google Sheets, or print it.

A construction change order template is a one-page record that turns a scope change into a signed amendment to the contract. It lists the change, the price, the days added or saved, and the signatures that make it binding. Use the free template below for every change order, whether it is a $900 outlet relocation or a $60,000 structural fix, so the paperwork looks the same and nothing gets skipped.

Most change order fights are not about the work. They are about missing paper. The crew did the extra footing, the owner said yes on the phone, and three months later nobody agrees on the price. A standard form, filled out before the work starts, is the cheapest fix there is.

What a change order form is for

A change order modifies the contract sum, the contract time, or both. It usually starts as a change order request from the contractor or a request from the owner or architect. Once both sides agree on scope, price, and time, the change order is signed and becomes part of the contract documents. From then on it can be billed on the next pay application, typically as a new line on the schedule of values.

This template is built as a log-style sheet, one row per change order, so a project manager can see every change on a job in one place and still print a single row as the form for signature. Add a header with the project name, contract number, owner, and original contract amount when you print it.

How to fill in each column

  • CO number: number change orders in order and never reuse a number, even if one is rejected. Gaps raise questions in an audit.
  • Date issued: the date the change order is sent for signature, not the date the issue came up.
  • Description of change: say exactly what is added, removed, or changed. Reference the RFI, drawing, or field directive that caused it.
  • Reason: owner request, unforeseen condition, design error, or code requirement. This matters later if the change is disputed.
  • Labor, material, and markup: break the price out. Owners approve faster when they can see how the number was built.
  • Total amount: the net add or deduct. Use a minus sign for credits.
  • Days added: the schedule impact in calendar or working days, matching how your contract counts time. Write 0 if none, never leave it blank.
  • Status and approved by: pending, approved, or rejected, and the name of the person who signed.

Common mistakes

  1. Doing the work before the form is signed. If the contract allows it, get at least a signed field directive or change directive first.
  2. Lumping labor, material, and markup into one number, which invites a line-by-line argument.
  3. Leaving out the reason, so a design-error change later looks like contractor scope.
  4. Not adding approved changes to the next pay app. Signed money still has to be billed.
  5. Forgetting to flow the change down to the subcontractor whose scope it affects.

  • Sample data only. Replace the example rows with your own job.
  • Number change orders in sequence and never reuse a number.
  • Use negative amounts for credits so the log totals correctly.
  • When printing a single change order for signature, add the project name, contract number, original contract sum, and revised contract sum at the top, plus signature lines for contractor and owner.
  • Carry approved totals to your change order log and the next pay application.

Frequently asked questions

Is a change order legally binding?

A change order signed by the parties authorized in the contract generally becomes part of the contract. Check your contract for who can sign and whether changes must be in writing.

What is the difference between a change order request and a change order?

A change order request is the proposal: here is the change and what it costs. A change order is the agreed, signed version that amends the contract.

Can I use this change order template in Excel?

Yes. Download the CSV and open it in Excel or Google Sheets. Add formulas for the total column and save it as your own workbook.

Should credits go on a change order?

Yes. Deleted scope is a deductive change order. Show it as a negative amount so the revised contract sum stays accurate.
