Formwork Calculator
Compute required formwork contact areas.
Project & Input Data
no.
%
An editable user-defined allowance — not a universal engineering requirement.
no.
How many times one panel set is reused on this element.
Engineering Assumptions
- Contact area only — props, walers, ties and release agents are excluded.
- Reuse cycles divide the total contact area to give the panel area to procure.
- All percentages and inputs are user-defined; the calculation is purely arithmetic and assumes no particular code or specification.
Formula Summary
- Gross contact area = L × H × faces
- Net area = max(gross − deductions, 0)
- Total area = net × (1 + waste%)
- Panel area = total ÷ reuse cycles

Engineering Insight
Formwork cost is driven more by reuse cycles than by panel price; one extra cycle can cut the purchased quantity noticeably.
Recommended Action
Align the reuse cycles with the actual pour programme and verify deductions against the structural drawings.
