You already have the reinforcement layout from the structural engineer: enter the dimensions and the bars of the drawings and PRAXAO returns the concrete volume, the formwork area, the length and weight of bars and stirrups and the steel per cubic metre. It does not choose any section, bar or spacing.
Enter the dimensions to see the drawing.

Preliminary estimate from the values entered: not a structural validation and not an execution plan. Check the local rules and the manufacturers’ data.

Concrete: 0.750 m³. Formwork: 12.00 m². Longitudinal bars: 56.00 m, 49.72 kg. Stirrups: 84 pieces, 73.92 m, 16.41 kg. Steel in total: 66.12 kg, i.e. 88.2 kg per m³ of concrete (offcuts at 0 %, cover 3 cm, hooks 10 diameters).
No. It counts a reinforcement layout you already have. Sections, bar diameters, spacings, cover and lap lengths come from the structural engineer’s drawings; the tool never proposes them.
They depend on the project and the exposure. The values shown are only starting points. With a lap of 0 the bars are counted at the element height only, so the steel is a minimum, and the tool says so.
Starter bars from footings, ties, spacers, extra bars at openings, bar zones that differ along a beam, and the second layer of a slab (run the tool once per layer). The engineer’s bar schedule takes precedence over this estimate.
Weight per metre by diameter, total length, laps, waste and 12 m bars: the method to order reinforcing steel, with an example.
Concrete, formwork, pours, stripping and reinforcement by mark for a column, footings and a beam, with a worked example.
Weight of reinforcing steel from diameter and length, laps included, and the 12 m bars to buy.
Volume of concrete for slabs, footings and columns, with waste margin and cement, sand and gravel quantities.
Volume of an excavation, swollen volume to haul, truck loads and weight of soil from the dimensions.
