Power Distribution Estimating Services
Request a power distribution takeoff or priced estimate for service entrances, switchboards, panelboards, transformers, busway and feeders. Reconcile the issued one-lines and schedules before applying vendor prices.
Bid deliverable: Tagged gear counts, feeder raceway and conductor quantities, and a record of supplier inclusions or exclusions. Confirm utility, civil, testing and commissioning boundaries in the quote. Review published electrical takeoff samples →
One-Line Reconciliation
Every feeder verified against single-line and floor plans.
Gear Schedules
Switchgear, panelboards, disconnects & ATS itemized.
Drawing-Based Takeoffs
Measure issued feeder routes, pull boxes and bends; identify missing design information.
Schedule confirmed after review
Fast turnaround for distribution bid deadlines.
Power Systems Covered in Our Takeoffs
Power distribution is the backbone of any commercial or industrial electrical build. Our estimators provide exhaustive measurement and bill-of-material takeoff:
Power Distribution Deliverables
Feeder Schedule Table
Tabulated origin, destination, length, wire gauge, conduit size, pull box locations, and elbow counts.
Marked One-Line Diagrams
PDF single-line schematics color-checked against physical floor layout drawings.
Gear Bill of Materials
Ready to email directly to gear distributors (Square D, Eaton, ABB, Siemens) for manufacturer pricing.
Rigging & Installation Labor
Labor hours adjusted for equipment setting, heavy wire pulling, and feeder terminations.
Price a defined power distribution package
Reconcile each feeder origin and destination between the one-line, panel schedule and physical routing plan. Keep cable length, raceway length, parallel sets, terminations and equipment counts separate so supplier quotations and installation allowances remain traceable.
Documents and vendor inputs to provide
Send one-lines, feeder schedules, distribution layouts, equipment schedules, grounding details, utility requirements, specifications and addenda. State the US project location, current revision, bid deadline and any quoted gear packages or exclusions.
Clarify civil, utility and equipment boundaries
Identify responsibility for excavation, duct banks, concrete encasement, backfill, utility-owned equipment, rigging, testing and commissioning. Gear quotes should identify freight, taxes, terminations and installation exclusions. Document routing assumptions where the design does not show a complete route.
Engineering design, conductor sizing, fault studies and protective-device coordination are separate from measuring the issued design. For the wider package, review industrial electrical estimating or commercial electrical estimating.
Power distribution takeoff scope
For service equipment, feeders, switchgear, panels, transformers, grounding, and site-distribution bid packages. Keep the engineer’s design basis and utility boundaries visible.
Documents that define your estimate
One-line diagrams, feeder/cable schedules, service and switchgear details, equipment layouts, grounding plans, utility requirements, civil profiles, vendor quotes, and testing specifications.
| Scope item | Measurement | Source to reconcile | Item to clarify |
|---|---|---|---|
| Gear and transformers | EA by tag/rating | One-line, equipment schedule, and vendor quote | Accessories, metering, protection, factory options, and quote exclusions |
| Feeders and busway | LF by specified configuration | Route lengths, elevations, and termination locations | Parallel sets, conductor quantities, splices, supports, and pull access |
| Underground distribution | LF/EA and excavation quantities | Duct-bank sections, profiles, handhole and manhole details | Concrete, spacers, trenching, dewatering, backfill, and restoration |
| Grounding and acceptance | LF/EA and test allowances | Grounding details and project acceptance criteria | Specialist testing, utility coordination, and commissioning interfaces |
Inclusions, exclusions, and responsibilities
Confirm utility-owned equipment, civil excavation, protection studies, arc-flash analysis, medium-voltage termination, testing, and energization responsibilities. Measure the specified design; do not choose equipment ratings from a generic online estimate.
How should incomplete switchgear quotes be carried?
List the supplier, quote date, validity period, included equipment, exclusions, freight, taxes, and lead-time assumptions. Show missing components as provisional allowances for review rather than presenting a complete fixed equipment price.
Confirm the fee and review deadline
Send the project location, current drawing revision, included systems, required outputs, and bid deadline. The proposal should state the estimating fee, delivery date, price/labor assumptions, and revision terms before you authorize work.
Inspect the published electrical takeoff samples for measured quantities and units. The commercial and multifamily excerpts illustrate selected electrical scope; they do not establish completed industrial or instrumentation assignments.
