Electrical estimates

A commercial electrical estimate is a takeoff and cost summary of the devices, fixtures, raceway, wire and equipment on your electrical plans.

The service

What you send. What you get.

You send

  1. Electrical power, lighting and systems plans
  2. Panel schedules, one-line diagram and light fixture schedule
  3. Electrical specification sections
  4. Mechanical and equipment schedules that need power connections
  5. Addenda and your labor units or rates and material pricing

Start with a short description. We arrange document sharing after confirming the work.

You get

  1. Device and fixture countsCounts by type, room and sheet, tied to the revision you sent.
  2. Raceway and wire takeoffConduit and wire by size, with the routing assumptions used written out.
  3. Cost summaryQuantities priced with your approved labor units or rates and material pricing.
  4. Open questionsCircuiting gaps, fixture schedule conflicts and equipment connections that need an answer.

Typical buyers: Electrical contractors bidding commercial work; Electrical subcontractors pricing tenant improvements; General contractor estimators checking electrical bids.

What we measure

Measured from your plans.

The estimate counts devices, fixtures and panels by type and measures branch conduit and wire by size, priced with rates you approve, plus assumptions and open questions. We confirm fit and a fixed quote after reviewing your documents.

Before we start

Questions to resolve and work not included.

Questions we help identify

  • Fixture type on the plan missing from the fixture schedule
  • Circuiting and homeruns not shown, so branch routing is assumed
  • Equipment connection responsibility not assigned between trades
  • Panel schedule loads do not match the one-line diagram

Not included

  • Electrical design, load calculations or code review
  • Utility company charges and service work by others
  • Fire alarm, security and low-voltage systems unless added to the scope
  • Site visits and field verification of existing circuits

Questions

About electrical estimates.

What do I need to send for an electrical estimate?

The electrical plans, panel schedules, one-line diagram, fixture schedule, specification sections and all addenda. A priced estimate also needs your labor units or rates and material pricing.

How is branch wiring measured when circuiting is not drawn?

We state the routing assumption used and list it as an open question. Your team can accept it or give us a different basis.

Are fire alarm and low-voltage systems included?

Only when you add them to the scope and the documents show them. We confirm the split during scope review.

Send the plan set details.

We confirm availability, scope, price and timing before any work begins.
