Electrical Bid Estimation — AI Calculates Cables, Outlets, and Panels for You

You're an electrical contractor and bid estimation takes too much time. Massoi reads electrical blueprints, calculates wire runs, outlet counts, and panels automatically — you focus on installation work.

Do You Recognize These Electrical Contractor Challenges?

Electrical blueprints contain a massive amount of detail. Counting every outlet and linear foot of wire by hand is frustrating.

Counting Outlets Is Tedious

Electrical blueprints can contain hundreds of outlets, switches, and light fixtures. Counting each one by hand is slow and error-prone.

Wire Runs Are Estimated by Eye

Accurately measuring wire routes from blueprints is difficult. Estimation errors in wire lengths directly impact material costs.

Power and Low-Voltage Separately

An electrical bid requires separate calculations for power, low-voltage, and data systems. Managing the overall scope is laborious.

How Does Electrical Bid Estimation Work?

Three steps from blueprints to a complete electrical bid

Upload Electrical Blueprints

Drag and drop PDF, DWG, or IFC files into Massoi. AI supports floor plans, panel schedules, and wiring drawings.

AI Does Quantity Takeoff Automatically

AI identifies outlets, switches, light fixtures, wire, and panels, and calculates all quantities in seconds.

Review and Send Bid

Review the bill of quantities, add your unit prices, and send a professional bid in PDF format — all from the same tool.

Features Tailored for Electrical Contractors

Massoi understands electrical blueprints — cables, outlets, panels, and light fixtures are identified automatically.

Linear Feet of Cable Automatically

AI measures cable routes from blueprints and calculates linear feet by cable type — Romex NM-B, THHN, MC, Cat6, and others.

Outlets and Switches

Power outlets, switches, push buttons, and data points are identified and counted automatically from blueprints.

Panels and Circuits

Main panels, distribution panels, and sub-panels are extracted from blueprints. Circuit counts and feed cables itemized.

Light Fixtures and Controls

Light fixtures are identified by type — recessed, surface-mounted, and pendant. Lighting controls are also counted.

Low-Voltage and Data

Fire alarms, security systems, antenna points, and data outlets are identified as separate groups.

Cable Trays and Installation Materials

AI calculates cable tray, conduit, and raceway linear feet based on cable routes automatically.

What Does AI Recognize in Electrical Blueprints?

Massoi's AI is trained on electrical blueprints. It recognizes all the most common electrical components automatically.

Receptacles (single, duplex, GFCI, weather-resistant)
Switches, toggle switches, and dimmers
Light fixtures (recessed, surface, pendant, and outdoor)
Cables (Romex NM-B, THHN, MC, Cat6, coaxial)
Main panels, distribution panels, and sub-panels
Fire alarm devices and smoke detectors
Emergency and exit lighting
Data outlets and low-voltage drops
Cable trays, conduits, and raceways
Grounding and bonding

What Does an Electrical Job Cost? 2026 Unit Price Benchmarks

Common electrical contractor unit prices for bid estimation. Prices are installation labor only, excluding materials. Source: regional contractor pricing data, 2026.

Work Item	Unit	Price (USD, ex. tax)
12/2 Romex NM-B installed	$/ft	1.20–2.20
10/2 Romex NM-B installed	$/ft	1.50–2.80
Single-gang receptacle wired	$/unit	32–62
Switch installed and wired	$/unit	36–70
Light fixture (recessed, pendant) installed	$/unit	55–130
Sub-panel (12 circuits) installed	$/unit	950–1,800
Cable tray (8" wide) installed	$/ft	10–18

Prices are indicative and vary by region, project size, and complexity. Use your own contracting data as the basis for bids.

5 Most Common Mistakes in Electrical Bid Estimation

Even experienced electrical contractors make these mistakes — each one eats directly into your margin.

Low-voltage gets tacked on as an afterthought

TV outlets, data drops, fire alarms, and security devices often get estimated visually or copied from a previous project. A single office project can have 80+ data drops at $70–140 each. Walk through the low-voltage layer systematically.

Wire runs are estimated as straight lines

Actual cable run lengths are 15–30% longer than the shortest distance on the blueprint, because cable follows trays, raceways, and ceilings. Don't measure point-to-point — include the route's bends and vertical drops.

Raceways and conduits get forgotten

Cable trays, raceways, and PVC conduit are 8–15% of total cabling cost. On top of that you need supports, penetrations, and firestop — all separate line items.

Testing, commissioning, and reports get omitted

Acceptance testing, measurements (insulation resistance, ground continuity, GFCI tests), and the documentation take 4–12 hours per project. Required testing reports aren't part of the $/ft cable price.

Layout changes aren't budgeted upfront

On retrofit projects, 5–15% of outlets and switches get moved during construction. Include a unit price for change-order work ($/hour or $/move) in the bid — that way change-order billing is straightforward.

Frequently Asked Questions About Electrical Bid Estimation

What does electrical bid estimation include?

An electrical bid covers power, low-voltage, and data systems: cabling, outlets, switches, light fixtures, sub-panels, lighting controls, fire alarm devices, antenna and data drops, plus cable trays and conduits. The bid also includes acceptance testing and required code-mandated inspections.

What does an electrical job cost per square foot?

On new construction, a full electrical scope typically runs $5–10 per square foot, with retrofit projects in the $7–14 range. Multi-family is at the lower end thanks to scale; single-family is higher. The price covers power, lighting, and basic low-voltage.

Does AI read electrical blueprint symbols?

Yes. Massoi's AI is trained on electrical blueprints and recognizes standard NEC symbols: receptacles (single, duplex, GFCI, weather-resistant), switches, light fixture symbols, fire alarm devices, and low-voltage components. Recognition works on both CAD blueprints and scanned PDFs.

How accurate is AI-powered electrical takeoff?

In practical tests Massoi reaches 95–98% accuracy compared to manual takeoff when the source blueprint is legible. Outlets and switches are counted essentially error-free. Manual electrical takeoff usually has 5–15% error because low-voltage and data drops get missed. AI checks every layer systematically.

Can Massoi handle both HVAC and electrical bids for the same project?

Yes. The same project can include both electrical and HVAC blueprints, and AI handles each as a separate bid section. This is useful for design-build contracts and integrated MEP work. See also our HVAC bid estimation page.
