Formwork Calculators

Formwork calculators: lateral concrete pressure on wall and column forms to ACI 347R-14, with plywood sheets, studs, walers, ties and tie loads, plus contact area for slabs, beams, columns, walls and footings.

Beam Formwork CalculatorCalculate beam formwork area (soffit plus sides below the slab), plywood sheets, props, side clamps and the approximate load on each prop. Metric and imperial.Column Formwork CalculatorCalculate lateral concrete pressure on column formwork to ACI 347R-14, plus contact area, plywood sheets, clamp or yoke sets and concrete volume.Footing Formwork CalculatorCalculate formwork for pad and strip footings: side area, plank rows and total plank length, and stakes. Includes concrete volume. Metric and imperial.Formwork Area CalculatorCalculate formwork contact area (shuttering area) for slabs, beams, columns, walls and footings, with openings deducted, wastage and plywood sheets.Formwork Cost CalculatorEstimate formwork cost over a job from contact area, pours and reuses, with material, labour and consumables rates in any currency, per m² or ft² poured. Free accountFormwork Material EstimatorEstimate slab formwork materials (plywood sheets, joists, bearers, props, load per prop and release agent) from slab size, thickness and support spacings. Free accountFormwork Panel CalculatorWork out how many system formwork panels of each size a wall needs: layout along the length, stacking to pour height, filler strips, joints and corners. Free accountFormwork Plywood CalculatorCalculate plywood sheets for formwork per set and over the whole job from contact area, sheet size, number of pours and uses per sheet, with sheet weight. Free accountFormwork Tie CalculatorCalculate formwork ties: number, load per tie, utilisation against the tie's safe working load, maximum spacing and tie length, from ACI 347 pressure. Free accountFormwork Wastage CalculatorCalculate formwork sheet wastage from cutting and from damage over repeated uses, the overall waste percentage, and how many sheets to buy for the job. Free accountSlab Edge Formwork CalculatorCalculate slab edge formwork length and area, number of edge boards and braces for a rectangular or any-shape slab, including stair and service voids.Stair Formwork CalculatorCalculate formwork for a cast-in-place concrete stair flight (sloping soffit, stringer sides and riser boards) from rise, riser, going, width and waist.Wall Formwork CalculatorCalculate lateral concrete pressure on wall formwork to ACI 347R-14, plus plywood sheets, studs, walers, form ties and load per tie. Metric and imperial.
