Electrical Estimating Mistakes That Kill Profitability
From fixture counts to feeder lengths, electrical packages punish incomplete takeoffs. Fix these common misses before bid day.
Electrical estimating fails quietly. A missing panel, undersized feeder, or ignored low-voltage scope can erase the entire job profit after award.
High-Risk Misses
- Counting fixtures without verifying circuiting and controls
- Ignoring gear lead times and temporary power needs
- Underestimating conduit bends, supports, and firestopping
- Treating low voltage as 'someone else's problem'
- Skipping coordination with mechanical equipment connections
A Cleaner Electrical Workflow
Build from the one-line and panel schedules outward. Lock device counts, then quantify feeders, branch, and specialty systems. Price labour with productivity that matches the building type—hospitals are not warehouses.
