Apex Electric Estimating Inc provides professional power distribution estimating services for commercial, industrial, and infrastructure electrical projects nationwide. Power distribution is the backbone of every electrical system — from the utility service entrance to the final branch circuit. Accurate power distribution estimating ensures your bid covers every component, connection, and labor hour required to deliver a safe, code-compliant, and functional electrical system.
Our specialized estimators analyze your construction drawings to deliver line-item material takeoffs, labor calculations, and bid-ready packages for every power distribution component: service entrances, switchgear, distribution panels, feeders, transformers, motor controls, raceways, and grounding systems. We price with zip-code-calibrated material costs and local labor rates so your bid reflects true project costs.

Our Power Distribution Estimating Process
- Drawing Review — We analyze architectural, electrical, and structural plans, specifications, panel schedules, one-line diagrams, and load calculations to capture every power distribution component.
- Quantity Takeoff — We measure conduit runs, wire lengths, device counts, and equipment quantities using Trimble Accubid, PlanSwift, and Bluebeam Revu. Quantities are cross-checked against schedules for accuracy.
- Pricing & Labor Calibration — We apply zip-code-calibrated material pricing from regional distributors and local labor rates. Union and merit-shop rates are applied based on project jurisdiction.
- Bid Package Assembly — You receive an editable Excel file organized by CSI division, color-coded marked-up plans, PDF summary, and optional basis-of-estimate documentation.
Software Used for Power Distribution Estimating
- Trimble Accubid — Electrical estimating with integrated power distribution databases
- PlanSwift — Digital plan takeoff for conduit and raceway measurement
- Bluebeam Revu — PDF markup and quantity extraction
- RSMeans — National and local electrical cost data
- Microsoft Excel — Custom bid packages with your firm’s formatting
Frequently Asked Questions About Power Distribution Estimating
Q: What documents do you need to estimate power distribution? A: We need the complete electrical construction documents: one-line diagrams, panel schedules, load calculations, conduit and cable schedules, architectural and structural plans, specifications, and any addenda. We can start with partial documents and update as more become available.
Q: How accurate are power distribution estimates? A: We maintain a verified 100% accuracy rate tracked against final closed-out field costs across 5,000+ completed electrical projects. Power distribution is our core specialty — we do not estimate HVAC, plumbing, or structural trades.
Q: Do you estimate high-voltage power distribution systems? A: Yes. Our power distribution estimating covers systems from 120V branch circuits through 15kV medium-voltage distribution. We estimate medium-voltage switchgear, transformers, cable terminations, and protective relay systems for industrial and utility projects.
Q: Can you provide estimates for Design-Build and CMAR projects? A: Yes. We provide power distribution estimating for all project delivery methods including design-bid-build, design-build, CMAR, and IPD. We include GMP support, value engineering alternates, and cost-reimbursable documentation as needed.
