What is an electrical takeoff?
An electrical takeoff is the measured and counted scope used to build an estimate. It includes devices, equipment, wiring and pathways, organized so quantities can be reviewed and priced.
Separate standard items and quoted packages
Count conduit, boxes, wiring devices and wire using a consistent system. Identify equipment packages that need supplier quotes, such as luminaires, switchgear, generators and fire alarm equipment. Check package inclusions before adding separate costs.
Clarify equipment requirements
Use the drawings and specifications to identify equipment ratings, accessories and installation requirements. For existing equipment, request the information needed to confirm compatibility. Record assumptions and unresolved questions.
Request package pricing early
Send reviewed quantities and current documents to suppliers early enough to clarify scope. If the takeoff is still developing, identify the preliminary quantities and send revisions when they change. Reconcile supplier counts with your own.
Count and measure systematically
Work by system, area or drawing sheet. Mark each counted device and measured route. Record panel locations, equipment connections and installation details that affect the assemblies and labor.
Use a project-specific system checklist
Adapt your checklist to the project rather than assuming every job has the same systems.
- Demolition and temporary electrical work
- Interior and site lighting
- Distribution, generation and feeders
- Branch power and equipment connections
- Fire alarm, security and communications
- Specialist systems specified for the project
- Grounding, bonding and lightning protection
Review before pricing
Check missing systems, duplicated counts, measurement units and drawing revisions. Then connect quantities with assemblies, labor and prices. AiE-powered drawing takeoff and AiE Image Matching assist the process while you review the results. See the full electrical estimating checklist.
