After the contract is signed

Price the change.
Document the decision.

Turn additions, credits, markup, and schedule impact into one reviewable change-order scenario before work proceeds.

Before approval

Require a complete written change.

A useful change order identifies the original contract, the reason, added and removed scope, all-in price adjustment, markup basis, payment date, schedule effect, signatures, and any permit or inspection consequence.

Do not rely on the calculator alone

  • Check whether the contract permits the proposed markup.
  • Confirm credits are documented, not silently absorbed.
  • Do not authorize vague “time and materials” work without controls.
  • Keep the signed change with drawings, photos, invoices, and inspection records.
Educational scenario—not legal advice: The signed contract and applicable law control whether a change is valid, who may authorize it, how it is priced, and when payment is due.
