Change orders and contracts

How do you get change orders signed before doing the work?

Set the rule at kickoff, make it fast and easy for the owner to sign, and train the field to stop and call the office before starting extra work. When work truly cannot wait, get a written directive with a not-to-exceed amount.

To get change orders signed before doing the work, make "no signature, no extra work" a stated rule from the kickoff meeting, price changes within a day or two so the owner is not waiting on you, send them in a format the owner can sign from a phone, and train your foremen to stop and call the office whenever someone asks for something new. When the work cannot wait, get a written directive with a not-to-exceed number before the crew starts, and convert it to a formal change order later. The fix is part process, part habit, and part spine.

Most contractors who do unsigned extra work are not careless. They are trying to keep the job moving and the client happy. The problem shows up months later, when the person who asked for the work has moved on and nobody remembers agreeing to the price.

Why unsigned change work is risky

  • Many contracts require written approval before changed work, so unsigned work may not be paid at all.
  • Contracts often set notice deadlines. Under the federal FAR changes clause, for example, if an oral or informal order is treated as a change, the contractor must give the contracting officer written notice, and no adjustment is allowed for costs incurred more than 20 days before that written notice (with a limited exception for defective specifications).
  • Unsigned work is invisible to the budget, so job costing looks worse than it is until the dispute is settled.
  • Your leverage disappears once the work is done.

Step-by-step: making signed-first the default

1. Set the rule at kickoff

At the pre-construction meeting, walk through the change process: who can request changes, who can approve them, the dollar limit for the owner's rep, how fast you will price them, and that extra work starts only after written approval. Put it in the meeting minutes. When the rule is announced on day one, enforcing it later does not feel personal.

2. Name the approvers in writing

Get the names of the people who can sign changes and their limits. A super's verbal "go ahead" is not approval if only the owner's PM can commit money.

3. Train the field to stop and call

Foremen get asked for extras on site every day. Give them one script: "Happy to do it. Let me get you a change order so it is approved before we start." Then a phone call or text to the PM. Make it clear the company backs them when they say it.

4. Price fast

The biggest reason owners push to start before signing is that pricing takes too long. Aim to turn simple changes around in one or two working days. Use a standard pricing breakdown so it does not get rebuilt every time. See how to price a change order.

5. Make signing easy

Send the change order as a short PDF or e-signature link, not an attachment buried in a long email. One page with scope, price, time, and a signature block. Follow up the same day by phone.

6. Use a directive when work cannot wait

Sometimes the work truly cannot stop: an inspector's correction, a safety issue, a sequencing problem that will idle three trades. Get a written change directive or field authorization signed by an approver, with a description, a not-to-exceed amount, and how the final price will be set. Track the work on signed daily T&M tickets.

7. Escalate unsigned items weekly

Keep a pending change list and review it in every weekly owner meeting. Anything older than two weeks gets raised to the owner's decision-maker.

Worked example: a framing change on a custom home

Say a builder on a $1.1 million custom home is framing the second floor. The homeowners walk the site on Saturday and ask the framing foreman to move a bedroom wall 18 inches to enlarge a closet.

The foreman uses the script and texts the PM a photo with the request. On Monday morning the PM prices it: framing labor, added material, an electrical relocation from the electrical sub, and a revised HVAC register location. Total, as an illustration: $2,340 and one added day for framing. The PM sends a one-page change order through e-signature at 11 a.m. The homeowners sign it on their phones that evening, and the crew moves the wall Tuesday.

Total delay to the job: one day. The electrical and HVAC subs got their own written changes from the builder the same afternoon, so their extras were priced and approved before anyone touched a wire or a duct. Without the rule, the foreman would have moved the wall Saturday, the electrical and HVAC subs would have billed extras weeks later, and the builder would be asking for $2,340 from homeowners who remembered it as "a small tweak."

Mistakes to avoid

  1. Letting the field approve or promise prices.
  2. Taking days or weeks to price small changes.
  3. Accepting approval from someone with no authority to commit money.
  4. Starting T&M work without signed daily tickets.
  5. Not putting the change process in the kickoff minutes.
  6. Letting unsigned items pile up until closeout.

What to do if work already started without a signature

It happens. When it does, write it up immediately. Send the owner a written notice the same day that you consider the work a change, describing what was requested, by whom, and when, and that pricing will follow. Start signed daily tickets for the remaining work. Then submit the priced change order within a few days. The longer the gap between the work and the paper, the weaker your position becomes, especially under contracts with strict notice windows like the federal one above.

Residential vs commercial

On residential jobs, the person asking for changes is usually the person paying, so it is easier to get signatures on the spot. The risk is informality. Homeowners often treat changes as favors. Some states regulate home improvement contracts closely, so check your state licensing board's rules on contracts and changes. See how to handle homeowner change requests.

On commercial jobs, approval often runs through an architect and owner's rep, which takes longer. Directives and not-to-exceed authorizations matter more there.

Templates and tools

Use a construction change order template and a change order log template. For when work has already started on a verbal OK, read how to handle verbal change requests from owners.

Smart Business Automator sends change orders for approval from the project and tracks who has signed and what is still pending. See change order approval automation.

Frequently asked questions

What if the owner refuses to sign but wants the work done?

Ask for a written directive with a not-to-exceed amount. If the owner will not put anything in writing, document the request, notify in writing that you consider it a change per the contract, and follow the contract's notice process before starting.

Is a text message approval enough?

It is better than nothing as evidence, but many contracts require a signed change order. Treat a text as a placeholder and get the formal change order signed quickly.

Can a superintendent approve a change order?

Only if the contract or owner gives them that authority. Get approvers and dollar limits in writing at kickoff.

What if the change is needed for safety?

Do the work needed to keep the site safe, then notify the owner in writing immediately and follow with a change order or claim under the contract's procedures.
