Orlando Low Voltage Estimating | Accurate Takeoffs & Cost Estimates

📝 Estimator's Field Note

"The most common scope gap I find in plan reviews is the coordination between the electrical contractor's work and the low-voltage systems. When the data, security, and AV systems are designed by separate consultants, there are almost always overlaps or gaps in the raceway and power requirements."

⚠ Bid-Day Risk Factor

Utility coordination lead times vary dramatically by jurisdiction. Always verify with the local utility before finalizing schedule-dependent pricing.

🔍 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.

Permits & Fees	$12,000	$18,500	+$6,500
Contingency	$18,000	$35,000	+$17,000
Total Estimated Cost	$690,900	$770,100	+$79,200 (11.5%)

⚠ Note: The reviewed estimate identified $79,200 in scope gaps and cost underruns that the initial takeoff missed. This is consistent with our experience — independent review typically catches 8-15% in unaccounted scope.
