Electrical Estimating
Devices, fixtures, panels and gear counted from the plans and schedules, with conduit and conductor taken off the actual routing rather than straight-line distances.
- EA
- devices, fixtures, panels, gear
- LF
- conduit and conductor by size
- CKT
- branch circuits by panel
- LS
- gear, testing, commissioning

Where bids go wrong
What other electrical estimates miss.
Feeder lengths taken from the actual routing, not straight-line distances between panels.
Fixture types counted from the schedule with controls, drivers and emergency ballast included.
Equipment connections coordinated from the mechanical and kitchen schedules, not the power plan.
Labor units applied by system and height — the same device costs more on a 30-foot ceiling.

FAQ
Electrical Estimating, answered.
Talk to an estimator
Not a salesperson. Same-day answers on working days.
+1 518 974 7222[email protected]Do you measure wire and conduit?
Yes. Conduit and wire are measured by size and type from the plans and one-line diagram, with fittings and supports included.
Are low-voltage systems included?
They are estimated separately under low voltage, fire alarm and access control unless you want them combined.
Can you use our cost book and labor rates?
Yes, and we prefer it. Your historical costs reflect your crews and your suppliers better than any published average. Send the template and we work inside it.
How does pricing work?
Pricing is per project and quoted before any work starts — no retainer, no minimum volume and no subscription.
Do you sign NDAs?
Yes. Drawings, specifications and pricing are treated as confidential by default, and we sign your NDA on request before any documents change hands.
