What Is a Change Order?
A change order is a formal record used when contracted work changes after an agreement begins. It documents what is being added, removed, or modified. A clear change order also records the reason, price adjustment, schedule effect, and required approvals. Contractors use these documents to reduce misunderstandings and protect project records. Owners benefit because every adjustment receives a visible cost and timeline explanation before work proceeds.
How to Use This Generator
Start with accurate project and contract information. Add the owner, contractor, and project manager details. Describe the requested change using specific language about materials, labor, locations, and affected work. Add each cost item separately whenever possible. The calculator combines line items with equipment, subcontractor, permit, overhead, profit, tax, and discount values. Review the revised contract amount before generating the document. Enter schedule changes as added or reduced calendar days. Finally, record the approval status and names of responsible parties.
Good Change Order Practices
Strong change orders are specific, measurable, and tied to the original contract. Avoid vague descriptions such as “extra work” without explaining what changed. Separate labor and materials when they need independent review. Use consistent numbering so later records are easy to audit. Attach drawings, quotations, photos, or field instructions when they support the request. Do not rely on verbal approval for significant changes. Confirm pricing and time impacts before changed work begins whenever the contract allows. Keep signed copies with invoices and project correspondence. Requirements differ by contract and jurisdiction, so this generator should support project administration rather than replace legal, accounting, or professional advice.

Frequently Asked Questions
1. What should a change order include?
It should identify the project, describe the change, show cost and schedule adjustments, and document approvals.
2. Can a change order decrease the contract value?
Yes. Deleted work, credits, or substitutions may create a negative change and reduce the revised contract amount.
3. Should labor and materials be listed separately?
Separate values usually improve transparency and make review easier for owners, contractors, and auditors.
4. Does this generator provide legal advice?
No. It creates a practical project document. Contract requirements and applicable laws should be reviewed independently.
5. When should a change order be approved?
Approval should generally occur before changed work begins, subject to emergency provisions and the governing contract.
6. What is the revised contract amount?
It is the original contract plus previous approved changes and the current change order adjustment.
