What should a construction change order include?
Include the original agreement reference, reason for change, exact added and removed scope, cost adjustment, schedule impact, attachments, exclusions, and authorization by the correct decision-maker.
Free Contractor Template
A copy-ready structure for documenting changed work, price, schedule, attachments, and approval—without pretending a generic template replaces your contract or legal advice.

A useful change order explains the difference between the approved scope and the proposed revision. It should let a reader understand what triggered the change, what work is added or removed, how price was calculated, what happens to the schedule, and who approved the decision.
Reference the original agreement and current drawings. Attach photos, sketches, estimates, selection records, or field notes that explain the change. Keep allowances, taxes, markup, credits, and exclusions visible rather than hiding them inside one lump sum.
Copy this structure into the company’s approved document system. Replace every bracketed prompt and remove sections that do not apply. The final language must remain consistent with the signed contract.

Common failures include describing only the price, forgetting removed scope, omitting schedule impact, attaching an unlabeled sketch, and performing changed work while approval remains ambiguous.
These resources help connect change documentation to scope, drawings, approvals, and client communication.

Requirements depend on the contract and jurisdiction. Written approval is generally stronger evidence than informal direction, but contractors should adapt the process with qualified legal advice.
That depends on urgency and contract terms. When practical, obtain approval first. If emergency work proceeds, document the direction, evidence, cost basis, and follow-up immediately.
State the number of calendar or working days, affected milestones, procurement consequences, and assumptions. Avoid vague wording such as schedule may change.
It may provide evidence, but enforceability varies. Preserve the communication and transfer the decision into the formal project record or approved change-order process.
No. It is a planning template. Adapt it to the signed contract and local requirements with qualified legal advice where needed.
