📝 Estimator's Field Note
"Change-order prevention starts at the takeoff stage. When we flag a discrepancy between the drawings and specs during our initial review — I'd say it happens on roughly 40% of projects — that's a potential change order we just prevented for the contractor."
🔍 Scope Gap Warning
Utility company metering requirements are a recurring scope gap. The meter cabinet type, location, and CT cabinet requirements vary by utility and are often not shown on the design drawings.
