Concrete quantities are generally taken off in measures of cubic yards, as this is the way the material supply companies charge for it. For accurate concrete estimating, the estimator must consider each of the following major components individually: formwork, reinforcing steel, ready-mix concrete, placement of the concrete mix, finishing of the surface, and curing. When estimating structural concrete, pay particular attention to requirements for concrete additives, curing methods and surface treatments. Special consideration for climate conditions as well as hot or cold weather conditions must be included in your estimate. Also include requirements for concrete placing and finishing methods and equipment.
