Electrical Estimating | Apex Accuracy Estimating
Detailed electrical estimating for commercial, industrial, and residential projects including panel schedules, conduit, wiring, fixtures, and low-voltage systems.
Our electrical estimating specialists deliver precise takeoffs and cost analyses for projects of all types and sizes. From commercial office buildings to industrial facilities, we calculate every wire, conduit, device, and fixture with meticulous accuracy. Our estimators use advanced electrical estimating software combined with up-to-date material pricing and labor databases to produce bid-ready packages that win projects. We cover all electrical systems including power distribution, lighting, low-voltage, fire alarm, security, and data/communications.

Frequently Asked Questions
What electrical systems can you estimate?
We estimate all electrical systems including power distribution, lighting, low-voltage (data/communications/security/fire alarm), emergency power, and specialty systems. Our estimators are experienced in NEC code requirements and local amendments across all 50 states.
Do you provide panel schedules and load calculations?
Yes, we analyze panel schedules, perform load calculations, size conductors and overcurrent devices, and provide complete panel schedules as part of our electrical estimating package.
Can you estimate design-build electrical projects?
Yes, our electrical estimators work closely with design teams on design-build projects. We can provide preliminary estimates during design development and refined estimates at each design phase.
How do you price electrical materials?
We maintain relationships with electrical suppliers and use real-time pricing from major electrical distributors. We also track manufacturer pricing trends and bulk discount opportunities to provide accurate, competitive material costs.
