Most change-order disputes are lost before the conversation starts because the field record is incomplete.
A usable daily log should capture four items every day: crew count by trade, materials delivered, weather delays, and scope variances noticed in the field. Keep entries short, but specific.
When the owner requests additional work, log it the same day and attach a photo. This creates a timestamped trail you can use for approvals and billing.
Teams that maintain clean daily logs close invoices faster and spend less time arguing over what happened on-site.
