A valid change order answers four questions: what changes, what it costs, how it affects time, and who approved it before the changed work proceeds.
Describe the scope precisely
Reference drawings, specifications, locations, quantities, products, labor, exclusions, and the reason for change.
Labels such as owner upgrade, field condition, design clarification, code requirement, allowance reconciliation, or correction should not replace actual scope.
Show complete pricing
Include labor, material, equipment, subcontractor, tax, freight, restocking, design, permits, testing, overhead, fee, and credits as applicable.
Unit prices and backup improve transparency when the scope is uncertain.
State schedule impact
Changes can affect design, submittal, procurement, sequencing, inspections, cure time, remobilization, and completion.
No-cost changes can still create delay, and cost increases can sometimes have no time effect.
Obtain authority before work
Identify who can request, price, recommend, approve, and fund a change.
Emergency or concealed-condition procedures should define limited authorization and prompt documentation.
Update the whole project
Approved changes should update contract value, budget, contingency, forecast, schedule, drawings, specifications, selections, lender records, and field documents.
A signed form that does not update the project record remains an isolated fact.
The BuildProof Four-Part Change Rule
Four-Part Change Rule turns the topic into a repeatable national workflow while preserving the local evidence required for a defensible project decision.
| Step | Required action | Exit test |
|---|---|---|
| 1. Scope | Define the exact addition, deletion, or revision. | The work is understandable. |
| 2. Price | Show complete cost and credit. | Financial effect is known. |
| 3. Time | State milestone and completion impact. | Schedule effect is known. |
| 4. Approve | Obtain required written authority. | The change can proceed. |
| 5. Integrate | Update every controlling document and forecast. | The project remains aligned. |
What to document
- Change request
- Reason and responsibility category
- Scope backup
- Price backup
- Time analysis
- Approval authority
- Lender treatment
- Updated drawings and schedule
Common failure modes
- Proceeding on verbal approval
- Pricing material but not labor or time
- Calling a change no-cost without schedule review
- Using change orders to correct defective work without clarity
- Failing to update forecast at completion
Frequently asked questions
Can a builder perform emergency work before approval?
Contracts may allow limited emergency action to protect life or property, with prompt notice and documentation.
Should every allowance overage be a change order?
The contract should define reconciliation, but cost and scope should remain visible and approved.
Can an owner reject a change caused by code?
Rights and responsibilities depend on contract, documents, law, and cause. Qualified review may be needed.
BuildProof next step
Do not allow changed work to proceed until scope, price, time, and authority are recorded, except under a defined emergency procedure.
