📝 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
Outdoor lighting and landscape power scope is often split between the electrician and the landscape contractor, creating a coordination gap. We flag this on every residential estimate.

📦 Coordination Note from Our Team
Low-voltage and AV rough-in needs to be coordinated with framing. The structured cabling panel location, media room conduit, and security keypad backboxes all need framing modifications that the framer needs to know about before they start.
