Estimate concrete volume, ordering, cost, and rebar-cage materials for a square or rectangular column.
Enter column length, width, and height to calculate the volume of a uniform rectangular prism. The planner converts the result to cubic yards or cubic meters, applies the order allowance, and reports bag quantities, ready-mix guidance, rough cost, and supplier notes. An optional cage takeoff estimates longitudinal bars and closed ties from the entered bar sizes, count, spacing, side cover, and end cover.
The volume formula assumes a straight column with a constant square or rectangular section. Capitals, corbels, haunches, pedestals, pilasters, tapered forms, and embedded blockouts should be measured separately. Form dimensions should represent the finished concrete section, and multiple identical columns can be totaled using the built-in quantity field after one section is checked carefully.
Column size, concrete strength, bar count, bar size, tie configuration, lap length, development, cover, and connections are structural requirements. The cage preset is provided only as editable takeoff input and should not be used to design a load-bearing column. Follow the drawings and have changes reviewed by the responsible engineer before purchasing steel or concrete.
The design volume is 8 cubic feet, or about 0.30 cubic yard. With a 5% allowance, the planning amount is about 0.31 cubic yard.
No. It estimates material from the bar and spacing inputs. Structural drawings or an engineer must specify the actual cage.
