Quantity takeoff or estimating sheet is the general form of listing and taking off types, sizes and quantities of material required in a bidding process of any construction work. This quantity takeoff sheet also includes ductwork, piping, labor, risk cost and summation of all the estimated expenditure.
To prepare a concrete estimate properly for bidding purposes the estimator must consider two facets of an estimate. The first is the quantity takeoff; the second is the pricing schedule.
A quantity takeoff of all items of concrete is the first step in preparing an estimate. All items of concrete material are listed on the quantity takeoff sheets. Since the concrete yardage in a job is the most important item, I get this down first along with related formwork, hand excavation, finishing and other items that can be gathered at the same time to expedite the takeoff.
