FIVE PRACTICAL ANSWERS
Pool Change Order Cost Control FAQs
Is a verbal approval enough?
Requirements vary, but material changes should be documented through the contract process before changed work proceeds where practicable.
Is every discovery an owner cost?

Should credits be included?
Yes. Removed work and unused allowances should be reconciled according to the agreement.
How do changes affect comparison?
Track cumulative value and schedule effect against the accepted baseline.
What if work must proceed urgently?
Follow the agreement and applicable requirements, preserve evidence, and obtain appropriate advice.
