Instructions & Best Practices

Use change orders to protect scope, timeline, and cash flow

When to use a change order

  • Any time the owner asks for work outside the signed scope.
  • When concealed conditions require additional labor, material, or equipment.
  • When architects, designers, or engineers revise plans after award.
  • When allowances or unit-price quantities exceed contract assumptions.
  • When schedule acceleration, resequencing, or premium labor is requested.

How to number them

  • Use sequential numbering beginning with CO-001.
  • Tie the number to the job number on all backup documents.
  • Reference related RFI, submittal, drawing revision, or email thread.
  • Log pending, approved, and rejected items in one master register.

What to document

  • Clear description of added, deleted, or revised work.
  • Pricing backup: labor hours, crew mix, supplier quotes, and markups.
  • Time impact in calendar days, including procurement or inspection delays.
  • Exact location, drawing detail, specification section, or field sketch.
  • Who requested the change and when the direction was given.

Legal tips

  • Do not start non-emergency extra work without written authorization.
  • Make sure the customer signs both cost and time adjustments.
  • Preserve emails, text messages, and site photos as backup.
  • Review contract clauses for markup caps, notice deadlines, and waiver language.
  • For regulated projects, confirm lender or owner representative approval requirements.

Pro tips for getting signatures quickly

  1. Send the change order the same day the issue is identified.
  2. Use a one-paragraph description and attach backup on a second page if needed.
  3. Offer a good / better / best option when possible to speed owner decisions.
  4. Have field staff photograph the existing condition before work begins.
  5. Update the log weekly so pending revenue does not fall through the cracks.
