Separate a change from a clarification
A clarification explains existing scope; a change alters it. Ask for written identification of the trigger, requested result, affected documents, alternatives, assumptions, and whether the original work is deleted or retained.
Review cost and schedule together
A useful change document states the price basis, taxes where relevant, payment timing, lead-time effect, sequence impact, extension of time, and any effect on connected trades, warranties, or approvals.
Update the project record
Keep approved changes with plans, selections, correspondence, photographs, invoices, inspection records, and the final handover package. Verbal direction should be documented through the agreed process.
Pool project change orders: common questions
Should work begin before a change is approved?+
Follow the contract and applicable law. In general, obtain a clear written description, price and schedule effect, and authorized acceptance before changed work proceeds.
What if a condition is urgent?+
Use the contract’s communication and emergency process, protect people and property, and document evidence, direction, cost, and follow-up promptly.
Do changes affect warranties?+
They can. Ask how revised products, installers, interfaces, and scope affect warranty responsibilities and documentation.
