Opening your workspace…
Measure the faces that touch concrete, enter the usable sheet area, and see the gross contact area and whole sheets side by side.
Follow the method, check the example and review the assumptions.
Contact area = length × width × faces × quantity. Allowed area ÷ sheet area, rounded up, gives purchase sheets.
A 4 m × 3 m soffit with one face has 12 m² contact area before wastage and sheet rounding.
This illustrates the method; your inputs determine your result.No. Formwork is measured on surfaces touching the concrete, while concrete is measured by volume.
No. The result is a gross planning count. Adjust your purchase plan for the planned reuse cycle.
