Electrical Estimating Services Counted, Measured and Labor-Loaded

Electrical estimates for electrical subcontractors and for general contractors who need a check number before they trust a sub quote. Devices are counted off the power and lighting plans, homeruns and feeders are measured as real routed lengths rather than straight-line distances, and labor is applied with published units by item.

What an Electrical Estimate Covers

The estimate is built the way an electrical contractor bids: item, quantity, material cost, labor unit, extended hours.

Service & Distribution

Everything from the utility point to the last panel.

  • Switchgear, MDP and panelboards
  • Transformers and disconnects
  • Feeder conduit and conductor
  • Grounding and bonding
Branch Circuits

Devices counted and homeruns measured circuit by circuit.

  • Receptacles, switches and plates
  • Homerun and branch conduit runs
  • Wire by size and insulation type
  • Boxes, straps and fittings
Lighting & Controls

Fixtures against the schedule, controls against the plan.

  • Fixture counts by type and mounting
  • Emergency and exit lighting
  • Occupancy sensors and dimming
  • Lighting control panels
Fire Alarm & Life Safety

Initiating and notification devices with their wiring.

  • Panels, pull stations and detectors
  • Horn/strobe notification devices
  • Fire alarm cable and conduit
  • Programming and acceptance testing
Low Voltage & Data

Structured cabling, security and AV where it is in scope.

  • Data drops and cable tray
  • Racks, patch panels and terminations
  • Access control and CCTV
  • Pathway and sleeve counts
Labor Units

NECA-style units by item, not a flat percentage of material.

  • Labor units applied per item
  • Difficulty and height factors
  • Temp power and site lighting
  • Local wage rates and burden
Deliverables

What You Get Back

Three files, every time — the numbers, the evidence behind them, and what we assumed to get there.

Priced Estimate

A line-item estimate in Excel or CSV, priced off your own cost library or a regional benchmark database, with material, labor, equipment and subcontract split out.

  • Line items grouped by CSI division
  • Material, labor and equipment split
  • Markup, overhead and profit applied
  • Excel, CSV or BidcoreAI project
Marked-Up Drawing Set

The measured drawing set comes back with every quantity traced on the sheet it came from, so your own reviewer can check a number without re-measuring it.

  • Colour-coded measurement overlays
  • Sheet and detail references
  • Scale and calibration recorded
  • Searchable PDF
Assumptions & Exclusions

A written basis of estimate: what was included, what was excluded, which allowances were carried, and the open questions worth issuing as an RFI before the bid goes out.

  • Basis of estimate memo
  • Inclusions and exclusions list
  • Allowances and contingencies
  • Suggested RFI list

How It Works

From Drawing Set to Bid-Ready

1
Send the drawings
Upload the plan set, specifications and any addenda through the request form — or paste a Drive, Dropbox or WeTransfer link if the set is large.
2
Scope analysed by the platform agent, then reviewed manually
The BidcoreAI agent reads every sheet, schedule and specification section and returns the full scope. An estimator then reviews it line by line against the drawings, so nothing is carried on the agent alone and nothing in the set gets missed. You get a fixed quote and a delivery date before any work starts.
3
Measured and priced
Quantities are measured in the BidcoreAI takeoff workspace, then priced against your cost library or a regional benchmark database.
4
Delivered and reviewed
You get the estimate, the marked-up set and the basis of estimate — plus a call to walk the numbers if you want one.
