📝 Estimator's Field Note
"One thing I've learned from estimating across different markets: the local utility's service entrance requirements are never quite what you expect. We always call the utility engineering department before finalizing a bid in a new jurisdiction."
🔍 Scope Gap Warning
The scope boundary between structured cabling and electrical for powered devices (PoE) is a frequent source of change orders. Who provides the power injectors, who terminates the Cat6 at the patch panel, and who commissions the active equipment — define this before bid submission.
