What it means
During estimating, an estimator goes through the project drawings and specifications and “takes off” every item needed: fixtures and devices counted from the plans, conduit and wire measured along their routes, panels and equipment from the schedules. The result is a list of materials with quantities, which becomes the basis for the estimate and for requesting quotes from distributors.
Takeoffs can be done by hand from printed plans or with digital takeoff and estimating software. Either way, the takeoff often ends up as a spreadsheet or export that has to be turned into a request distributors can quote.
An example: an estimator counts receptacles, switches and fixtures on the floor plans, measures conduit and wire runs, and lists the panelboards from the panel schedules. That list — with quantities and descriptions — is sent to two distributors for pricing.
Why it matters
- Accurate bids. Missed or miscounted items turn into lost margin.
- Faster quotes. A clean, clearly described takeoff gets faster, more comparable quotes from distributors.
