Electrical Estimate Sample at a Glance

Project	Commercial quick-service restaurant with drive-thru, Winchester, California
Scope	CSI Division 26 – Electrical (plus Division 01 general requirements)
Line items	123
Material cost	$152,893
Labor cost	$193,405 (2,035 man-hours at a $82.17/hr crew rate)
Direct cost	$346,298
Markups	Overhead 15%, profit 10%, insurance 4%, contingency 4%, sales tax on materials
Total bid	$472,426

Labor accounts for roughly 56% of direct cost on this project, which is typical for commercial electrical work with long branch-circuit conduit runs. That ratio is one reason a detailed electrical estimating service pays for itself: small errors in labor units multiply quickly across thousands of feet of conduit and wire.

What’s Included in This Electrical Estimate

The estimate follows the drawing set system by system, so you can check every number against the plans. Here is what each section covers.

Section	Items	What’s priced
General requirements (Div. 01)	1	Site supervision, final cleanup, dumpster
Lighting fixtures	19	Each fixture type by plan tag, manufacturer and catalog number: site lights, troffers, downlights, pendants, exit and emergency lighting
Power items	35	Receptacles (GFCI, WP, isolated ground, USB), junction boxes, disconnects, motor starters, EV charger, UL 924 transfer devices, emergency inverters
Conduit & wire	31	Conduit by size and type (EMT, PVC, underground) and wire by gauge, including grounding, Cat 5 and communication cable, with 10% wastage
Switches, sensors & controls	6	Single-pole and dimming switches, vacancy and occupancy sensors, daylight-zone dimming controllers
Communication & security	3	Telecom outlets, telephone cabinet with plywood backboard, security cameras
Service & riser	8	Pad-mount transformer (install only), meter socket, service conductors, main disconnects
Switchboard & panels	6	600A main switchboard (65kAIC, 208/120V, 3-phase, 4-wire) and five branch panels
Circuit breakers	14	Breakers by amperage and pole count, including 157 single-pole 20A breakers

Some of the larger takeoff quantities give a sense of scale: 9,350 LF of 3/4″ conduit and 17,741 LF of #12 wire after wastage, along with 60 standard duplex receptacles and 63 junction boxes.

How to Read an Electrical Estimate

Every line item in the sample uses the same columns. Once you know what each one means, you can audit any estimate in minutes.

• Description and CSI section. The item as shown on the drawings, with the fixture tag (for example, “14A”) so you can find it on the lighting plan.
• Unit of measure. EA (each) for devices and fixtures, LF (linear feet) for conduit and wire, LS (lump sum) for general requirements.
• Quantity, wastage and quantity with wastage. We add 10% to conduit and wire for cut-offs, bends and terminations. Devices are counted exactly, with 0% wastage.
• Unit and total material cost. Current supplier pricing for the specified product, not a generic allowance.
• Total man-hours. Labor units multiplied by quantity. In this sample a duplex receptacle carries about 0.6 hours and a 2×2 LED troffer about 1.6 hours.
• Crew rate and labor cost. A blended hourly rate for the crew, multiplied by man-hours. Rates are set for the project’s location.
• Total item cost. Material plus labor for that line, rolled up into the trade total.

Markup summary from the sample: Direct cost $346,298 + overhead (15%) $51,945 + profit (10%) $34,630 + insurance (4%) $13,852 + sales tax on materials $11,849 + contingency (4%) $13,852 = $472,426 total bid.

We set markups to match your company’s numbers. Tell us your overhead, profit and insurance rates and the estimate arrives bid-ready.

Our Electrical Estimating Process

1. Send your drawings. Upload electrical plans, the panel schedules, the riser diagram, and specifications through our contact page.
2. Scope review. An estimator confirms scope, exclusions and bid date. Any gaps between the drawings and specs are flagged early. For GC bids, we can add a full constructability review and scope gap analysis.
3. Takeoff and pricing. Every device, fixture, run of conduit and panel is counted, measured and priced with local material costs and labor rates.
4. Delivery in 24–48 hours. You receive an itemized estimate in the format shown in this sample, ready to review, adjust and submit.

Who Uses Our Electrical Estimates

Electrical subcontractors use them to bid more projects without adding in-house estimators. Our subcontractor estimating services cover every trade you might self-perform. General contractors use them to check sub bids and build complete budgets through our general contractor services. Owners and developers use them to set realistic budgets before going to bid.

Electrical is rarely priced alone. We also estimate the rest of the MEP package: mechanical, plumbing, and fire protection. Once you win the job, our shop drawing services and BIM coordination carry the project into construction.

Estimates Priced for Your Market

This sample is priced for Southern California. We adjust labor rates, material pricing and sales tax for wherever you build, including California, Texas, Florida, New York, and every other state on our service areas page.

Frequently Asked Questions

What does an electrical estimate include?

A complete electrical estimate includes itemized quantities, material costs, labor hours and markups for every system on the drawings. That covers lighting, power devices, conduit and wire, panels, breakers, service equipment, low voltage and controls, organized so each line can be checked against the plans.

How are labor hours calculated in an electrical estimate?

Labor hours are calculated by multiplying a labor unit for each item by its quantity. For example, about 0.6 hours per duplex receptacle or 1.6 hours per 2×2 troffer. Total hours are then multiplied by a local crew rate to get labor cost.

How long does an electrical estimate take?

Most electrical estimates are delivered within 24–48 hours of receiving complete drawings. Very large or multi-building projects may take longer, and we confirm the delivery date before starting.

What drawings do you need for an electrical takeoff?

Send the electrical plans, lighting and power layouts, panel schedules, riser diagram, and specifications. Fixture schedules and site plans help us capture site lighting and underground conduit accurately.

Can you use my company’s markups and labor rates?

Yes. We apply your overhead, profit, insurance and crew rates so the estimate is ready to submit. If you don’t provide them, we use typical rates for the project’s location and label every assumption.

Do you estimate other trades besides electrical?

Yes. We estimate all CSI divisions, including mechanical, plumbing, fire protection, concrete, framing, roofing and finishes. See our full list of estimating services or browse the general FAQ.
