Construction Change Order Template (Free + Editable)
A verbal "go ahead and fix that soft spot" feels like approval. Your invoice will disagree. A construction change order template turns that conversation into a signed document in about 10 minutes.
We built the template below from the standard AIA form, Caltrans' change order manual, and the paperwork commercial and municipal owners ask paving contractors for.
You'll get the editable form, a walkthrough of all 11 fields, a filled-in example from a parking lot job, and the pricing math that protects your margin.
Construction Change Order Template: 11 Fields
Every construction change order runs the same 11 fields, and here's what belongs in each one:
- Project and contract identifiers: project name, site address, contract number, contract date, and the owner's legal entity name
- Change order number and date: sequential numbering, with revisions written as CO-03R1 so both versions stay in the file
- Description of the change: plan and spec language, with station numbers, square footage, depth, and mix designation
- Reason for the change: owner-directed, unforeseen condition, design omission, code, or weather, since the reason drives who pays
- Supporting documents and photos: RFI numbers, plan sheets, takeoffs, supplier quotes, and dated photos, all named on the form
- Cost breakdown by line item: labor, material, equipment, and subcontractor, with units and unit prices on every line
- Margin on the changed work: your target margin applied as a divisor, inside whatever cap the changes clause allows
- Revised contract sum: original sum, prior approved changes, this change order, and the new contract total
- Schedule impact: working days added and the revised completion date, even when the answer is zero days
- Signatures and dates: owner, contractor, and the architect or engineer when the contract calls for one
- The clause that closes the file: a line stating this change order is full compensation, including the time extension
What Is a Construction Change Order Template?
A construction change order template is a reusable form that documents a change to a signed contract: the added or deleted work, the price, the schedule impact, and the signatures that make it binding. You fill in the blanks, both sides sign, and the document joins the original contract as an amendment.
Change orders show up on most jobs. AIA Contract Documents ran text analytics on 892,457 change orders across 18,229 completed projects and found the typical job carries between 1.7 and 11.29 change orders depending on its size.
Most of them land in the back half of the schedule, right when your crews are already committed somewhere else.
The form itself is the last step of a longer change-order process that starts the moment somebody spots the change. That guide covers how to spot a change, price it, and negotiate it. This page covers the document that ends the argument.
On paving work, the triggers are predictable. Subgrade fails under the first pass, drainage the survey missed shows up in a low corner, or a property manager decides to cut in a second entrance while your crew is already mobilized.
Anybody who has run paving project management on commercial lots knows the change is coming, and the only real question is whether the paperwork keeps up with the loader.
Public work leaves even less room to improvise.
Caltrans treats a change order as a legally binding document and requires a separate memo justifying each one, which is a decent bar to hold yourself to on private jobs too.
Download the Construction Change Order Template (Editable)
The construction change order template opens as a view-only Google Doc, which keeps the master copy clean for the next contractor who needs it. Your own copy is fully editable, and making one takes about thirty seconds:
- Open the template, click File, then click Make a copy.
- Save the copy to your own Google Drive or a shared team folder.
- Rename it with your job and change order number, along the lines of "Northside Lot CO-02."
- Delete the How to Use This Template block at the top before the form goes anywhere near a customer.
- Fill in Sections 1 through 11, then export to PDF for signatures.
Prefer MS Word? Open your copy, click File, then Download, then Microsoft Word (.docx). The tables, checkboxes, and section numbering survive the export intact.
The form also ships with four extras most blank templates skip: A change order log in Appendix A, a daily T&M ticket in Appendix B, a completed example in Appendix C, and a pre-send checklist in Appendix D.
Store the filled copies somewhere your office and your field crews can both reach. A signed change order sitting in one estimator's inbox may as well not exist, which is the entire argument for keeping project records centralized.
The 11 Fields Your Construction Change Order Template Needs
Owners push back on four of these more than the rest: There’s the description, the cost breakdown, the margin, and the schedule days. The other seven exist to make those four hard to argue with six months later.
1. Project and contract identifiers
Write the project name, site address or parcel number, original contract number, and the date you signed that contract.
Property managers run dozens of lots, so "Northside Business Park" means nothing on its own. Add the owner's legal entity name too, since the LLC on the contract is often different from the name on the building.
2. Change order number and date
Number your change orders sequentially and never reuse a number after a revision. Call the revision CO-03R1 and keep both versions in the file.
Clean numbering is what makes a change order log readable in October, and that log is the spine of any honest project tracking on a job that racks up three or four changes.
3. Description of the change
Describe the work using the same language as the plans and specs: station numbers, area in square feet, depth in inches, mix designation.
Vague descriptions are what owners dispute, so "repair failed subgrade" becomes "excavate 6,200 sq ft of failed subgrade in the truck court to 8 inches, install woven geotextile for subgrade separation, and place 8 inches of aggregate base." Writing it in the industry terminology the owner's engineer already uses will save you a week of email.
4. Reason for the change
State what caused the change and who originated it: owner-directed addition, unforeseen site condition, design omission, code requirement, or weather.
The reason drives who pays, and getting it on paper the same day heads off the "you should have caught that at bid" conversation three months down the road. One line does the job.
5. Supporting documents and photos
List every attachment by name: RFI number, plan sheet, spec section, quantity takeoff, supplier quote, and dated site photos.
Photos of a failed subgrade taken before you cover it up carry more weight than any paragraph you could write about it. Reference the attachments on the form itself so nothing wanders off from the file.
6. Cost breakdown by line item
Break the price into the same buckets you bid with: labor, material, equipment, and subcontractor.
Owners approve line items faster than lump sums because they can check your quantities against their own numbers. Show units and unit prices next to every total, and keep your labor rates consistent with the ones you used at bid time.
7. Margin on the changed work
Apply your target margin to the direct cost, and read your contract's changes clause before you do. Plenty of owner contracts cap the percentage you can add for overhead and profit on changed work, and some want subcontractor quotes attached.
Across completed projects, change orders move the contract total by an average of 3.2–5%, so the margin you protect here compounds over a full season.
8. Revised contract sum
Give the owner four lines: original contract sum, net change from previously approved change orders, this change order amount, and the new contract sum. Spreadsheet formulas cover the arithmetic, and this tends to be the first place contractors start automating the paperwork.
The math has to match your billing, because a revised total that disagrees with your pay application is the quickest way to get it kicked back, and now you're chasing a payment you already earned.
9. Schedule impact
Enter the working days added and the new substantial completion date, even when the honest answer is zero days.
Blank schedule lines read as "no impact" to an owner, and you lose the extension later. Two extra days in a truck court can shove the next three lots on your calendar, which is why scheduling construction projects around approved changes matters as much as the dollar figure.
10. Signatures and dates
Collect a printed name, title, signature, and date from the owner, from you, and from the architect or engineer when your contract calls for one.
The AIA's G701 form states plainly that it carries no effect until the architect, contractor, and owner have all signed. Three signed originals, one per party, is an old-school habit that still ends arguments.
11. The clause that closes the file
Add a short paragraph stating that this change order represents full compensation for the described work, including any time extension.
Contractors who skip that sentence end up fielding a second claim for delay costs on the same change six months later. Your attorney can hand you two sentences you'll reuse for years.
How to Price a Construction Change Order Without Giving Up Margin
Price the change off your own cost data, then apply margin as a divisor. Margin and markup are different math, and the gap between them is real money.
Say you have $16,934 of direct cost and a 22% margin target. Divide by 0.78, and your price is $21,710.26. Multiply by 1.22, and you get $20,659.48, which works out to an 18% margin and $1,050.78 handed over on a single change order. Repeat that across a season of parking lot work, and you've financed somebody's truck payment.
Three pricing methods cover almost every change you'll write:
- Contract unit prices when the change is more of something you already bid
- Lump sum when you can pin down scope and quantities up front
- Time and materials when nobody knows the extent yet, backed by daily tickets
Get those T&M tickets signed every day by whoever represents the owner on site. A stack of signed tickets converts into an approved change order with almost no friction. An unsigned stack converts into a negotiation you're going to lose part of.
Construction Change Order Template Example (Filled In)
Here's the form on a job most paving contractors will recognize. A 32,000 sq ft parking lot mill and overlay at $184,500. Your crew starts milling, the truck court fails under the loader across roughly 6,200 sq ft, and nobody bid subgrade repair.
The contract sum lines follow from there:
- Original contract sum: $184,500.00
- Net change from previous change orders: $2,310.00
- This change order (CO-02): $21,710.26
- New contract sum: $208,520.26
Schedule impact runs two working days, pushing substantial completion from June 12 to June 16. The reason for the change is an unforeseen site condition, backed up by eleven dated photos and a compaction test.
Three signatures close it out: The property manager, your project manager, and the owner's engineer.
Filling that out with your cost data in front of you takes under 15 minutes. The expensive version is the one you write from memory in August, after the crew has moved on and the photos have vanished into somebody's camera roll.
5 Mistakes That Make a Construction Change Order Template Useless
1. Starting work on a verbal approval
A property manager saying "just take care of it" gives you nothing to bill against. Get a signature before the loader moves, or at minimum an email confirming scope and price that you can attach to the form later that day.
2. Leaving the schedule line blank
Contractors fill in the money and forget the days constantly. Zero days is an answer, and writing it down protects you when the same owner asks about liquidated damages two months later.
3. Bundling unrelated changes onto one form
One change order should cover one change. Bundling subgrade repair with an owner-requested striping upgrade gives the owner a reason to dispute the whole document over the half they didn't want.
4. Pricing off a gut number
Guessing on the spot feels responsive and quietly kills margin. Pull your actual labor, material, and equipment rates, even when it costs you an hour, because the owner's engineer is checking your quantities against theirs.
5. Letting the form sit unsigned
Federal highway guidance has told agencies to settle changes well in advance of the contract completion date since 1960, and the reasoning holds up. Approval gets harder as the job winds down, because the owner has fewer options and less budget left to work with.
When a Change Order Template Stops Being Enough
A template handles one change on one job beautifully. Twenty active jobs with three changes each means 60 documents, 60 revised contract sums, and 60 opportunities for a crew to show up working from a superseded scope.
That's where the constraint shifts from paperwork to version control. The form is only as good as the system around it: whether your revised contract total reaches accounting, whether the added two days hit the schedule your foreman opens each morning, and whether the change makes it into the invoice at all.
Run Estimates, Change Orders, and Crews in One Platform
OneCrew is a platform built specifically for project-based asphalt and concrete paving contractors, and it replaces the patchwork of tools that lets scope changes slip through the cracks between the field, the office, and the invoice. Here's what OneCrew covers:
- Price change order scope off the same line items you bid so your margin target holds from estimate to invoice: OneCrew's estimating tools let you build estimates from aerial imagery or plan takeoff with configurable calculators for labor, materials, equipment, and subs.
- Push added scope and schedule days straight to the crew's schedule, not a revised text message: OneCrew's scheduling feature assigns crews and roles to specific job phases so your office and field see the same scope at the same time.
- Capture the field photos, surface conditions, and measurements that justify the change order before the crew moves on: The field management tools push mobile work orders and job details to crew phones and pull photos, time stamps, and field notes back to the office as conditions unfold.
- Send the change order proposal through the customer portal and collect the signature before the loader moves: OneCrew's proposals feature generates professional, branded proposals directly from your estimate.
- Keep every change, conversation, and revised contract total tied to the right customer record: OneCrew's CRM tracks every lead, conversation, and project history in one place.
- Bill the original contract plus every approved change in one invoice and sync to QuickBooks without double entry: OneCrew's invoicing tools generate invoices from the line items already in the platform and sync invoicing and payment data with QuickBooks Online.
You only need one platform that carries a change from the field photo all the way to the final invoice with every signature and line item accounted for. Book a demo and see how OneCrew handles change orders on your jobs.
FAQs
1. What is a construction change order template?
A construction change order template is a fill-in form that documents a change to a signed construction contract, covering the scope of the change, its cost, its schedule impact, and the signatures of the owner and contractor. Once every party signs, the form becomes part of the original contract.
2. Who has to sign a construction change order?
The owner and the contractor both sign a construction change order, and the architect or engineer signs when the contract calls for it. AIA's standard form carries no effect until all three parties have signed, so read your changes clause before any work starts.
3. Can I use my own construction change order template instead of AIA G701?
Yes, you can use your own construction change order template as long as your contract doesn't name a required form. Many owner contracts specify G701 or their own document, and submitting the wrong form can hold up payment, so check the contract first.
4. How much detail should a change order cost breakdown include?
A change order cost breakdown should include separate lines for labor, material, equipment, and subcontractor costs, with quantities and unit prices on each line. Owners approve itemized breakdowns faster because they can verify your quantities against their own estimate.
5. What happens if the customer won't sign the change order?
If the customer won't sign the change order, hold off on the extra work and put your position in writing the same day. Most contracts require written authorization before changed work begins, and performing it on a handshake puts your payment at risk.
