FAQ
How is formwork area found?
From the concrete contact area: column=perimeter×height, wall=area×faces, beam=(bottom+2 sides)×length, slab=soffit.
Plywood size?
Formwork plywood is usually 1.2×2.4m=2.88㎡; divide formwork area by it for sheet count.
Deduct openings?
Precise takeoffs deduct openings, but a ~10% waste factor usually absorbs them.
