Electrical Estimating

Electrical Estimating Services

Takeoffs and estimates for electrical contractors — lighting, power, cabling, containment and switchboards counted and measured from your electrical drawings, then scheduled by system for pricing.

How we measure electrical

See an Electrical Takeoff in 3D

Boards are scheduled from the single-line diagram, fittings and outlets counted room by room from the layouts, then containment and cabling measured along their routes, so every quantity is ready to price.

  1. The electrical layout is read room by room — walls, doors and every symbol checked against the legend and the drawing scale.
  2. The main switchboard and distribution board are scheduled from the single-line diagram, then the sub-main is measured along its route.
  3. Light fittings are counted by type on the ceiling layout, with the switches that control them.
  4. Power and data outlets are counted wall by wall from the small-power layout, room by room.
  5. Cable tray is measured along its route in the ceiling void, and every conduit drop from the void down to its outlet.
  6. Final circuits are measured from the board to every point, with an allowance for terminations, so the takeoff is ready to price.

Scope

What’s Included

The scope is confirmed with you before work starts, so you know exactly what will be measured and priced.

Cable trays and cable ladders carrying power cables along a concrete ceiling
  1. Lighting

    Light fittings counted by type from the lighting layouts and schedules, including emergency and exit lighting.

  2. Power

    Power outlets, switches, isolators and equipment connections counted by type.

  3. Cabling

    Sub-mains and final-circuit cabling in lineal metres by type and size, with routes stated where layouts are schematic.

  4. Containment

    Cable tray, ladder, conduit and trunking in lineal metres by type and size, with bends and fittings.

  5. Switchboards & distribution

    Main switchboards, distribution boards and metering scheduled from the single-line diagrams.

  6. Communications & security

    Data outlets, CCTV, access control and fire detection devices counted where shown on the drawings.

FAQ

Common Questions

Light fittings, power outlets, switches and other devices are counted by type; cabling, cable tray, ladder and conduit are measured in lineal metres; switchboards and distribution boards are scheduled from the single-line diagrams. Communications, security and fire detection can be included where shown.

Where layouts show devices but not cable routes, lengths are measured along assumed routes from each board to the devices it serves, with drops and terminations added as stated allowances. All routing assumptions are listed so you can review them.

Yes. Electrical is estimated as its own package. If you also need plumbing or mechanical, each can be prepared separately or combined into one services estimate.
