Electrical Estimating Services in Arizona

Electrical takeoffs and estimates for residential, commercial, industrial, data center and solar projects across Arizona. Service and distribution, feeders, branch circuits, devices, lighting and controls counted and measured from your drawings and priced for electrical contractors and GCs.

Overview

Electrical Estimates From One-Line to Last Device

Quick answer: Electrical estimating is the takeoff and pricing of a building’s electrical systems. The estimator prices service and distribution equipment from the one-line diagram and panel schedules, measures feeders and branch circuits by conduit and wire size, counts devices, lighting fixtures and controls from the plans, and adds boxes, fittings, supports, trenching, labor, testing and equipment. Labor is typically calculated from installation units for each item.

Electrical scopes are detailed and labor-intensive. A single commercial building can include thousands of devices, miles of conduit and wire, and switchgear with long lead times. Missing a feeder, undercounting fixtures or using the wrong conduit type can make a large difference in a bid.

Our electrical estimators work from the one-line diagram, panel schedules, power and lighting plans, fixture schedules and specifications. We price gear, feeders, branch circuits, devices, lighting, controls and specialty systems, and organize the estimate by system and area.

Electrical work pairs with our MEP Estimating Services, Low Voltage Estimating Services, Solar Estimating Services and Data Center Estimating Services.

In Depth

How We Estimate Electrical Work

Gear and distribution

Service equipment, switchgear, transformers and panels are priced from the one-line diagram and panel schedules by rating and configuration.

Feeders

Feeders are measured from equipment locations along realistic routes, then priced by conduit type and size and conductor size and quantity.

Branch circuits and devices

Devices, boxes, receptacles, switches and equipment connections are counted from the plans. Branch circuit conduit and wire are measured or calculated from circuit layouts.

Lighting

Fixtures are counted by type from the lighting plans and priced from the fixture schedule, with lighting controls, sensors and emergency units.

Labor

Labor is calculated from installation units for each item, adjusted for height, access, conduit type and site conditions. Testing, startup and commissioning support are added when required.

Expert Guide

Electrical Cost Drivers in Arizona

  • Copper and equipment prices: wire, switchgear and transformers are sensitive to commodity prices and lead times.
  • Cooling loads: large HVAC systems in Arizona increase service size, feeders and equipment connections.
  • Underground work: trenching for feeders and site lighting may encounter caliche, increasing excavation cost.
  • Utility requirements: APS, SRP and TEP each have service and metering requirements that affect equipment and coordination.
  • Labor demand: semiconductor, battery and data center projects have increased demand for electricians in the Valley.
  • EV and solar: chargers, solar and battery systems increasingly appear in residential and commercial scopes.

For federally funded projects, Davis-Bacon wage determinations are applied. For full MEP budgets, see our MEP Estimating Services.

Arizona Factors

Arizona Electrical Cost Factors

Large HVAC Loads

Cooling equipment drives larger services, feeders and disconnects.

Caliche Trenching

Underground feeders and site lighting trenches may require rock excavation.

Utility Service Requirements

APS, SRP and TEP service requirements and timelines affect cost and schedule.

Rooftop and Outdoor Work

Heat affects productivity for rooftop and site electrical work in summer.

Electrician Demand

Megaprojects across the Valley compete for licensed electricians.

Gear Lead Times

Switchgear and transformers may need early procurement and escalation.
