CSI Division 26
Electrical Estimating Services
Gear, feeders, branch wiring, devices and fixtures from power and lighting plans.
Our electrical estimators count every device, fixture and homerun on your plans. Switchgear and panels come off the one line diagram, feeders and branch circuits off the floor plans, and lighting off the fixture schedule, all organized so you can compare supplier quotes line by line.
Included in every estimate
- Switchgear, panelboards and transformers
- Feeders and branch wiring with conduit and conductor by size
- Lighting fixtures by type from the fixture schedule
- Devices: receptacles, switches, occupancy sensors
- Fire alarm and low voltage rough in
- Site lighting and underground raceways
The deliverable
An Excel workbook organized by CSI division. Every line shows the drawing or schedule reference, quantity, waste factor, unit, material cost, manhours and labor cost. A summary sheet rolls the divisions up and carries overhead, profit, insurance and contingency. You can hand it to a supplier for pricing or plug in your own rates.
Frequently asked
Do you take off from the one line diagram?
Yes. Gear and feeder quantities come from the one line diagram and panel schedules, cross checked against the floor plans.
Can you split normal and emergency power?
Yes. We can structure the estimate by system or by CSI section, whichever matches how you buy the work.
