Formwork Area Calculator
Formwork Area Calculator
Schedule shuttering for columns, beams and slab soffits.
Shuttering is counted by the surface touching fresh concrete. It is different from the concrete volume itself.
List columns, beams and slab soffits with their measured dimensions. Use the contact area schedule for quantity planning and assess support arrangements separately.
How to use Formwork Area Calculator
- Choose measurement unit. Enter shuttering rate.
- Add the entries in element schedule as separate rows. Include reference, element, length / height, width, depth and quantity for each row.
- Select Calculate estimate. Read the returned values alongside the assumptions below before copying, exporting or acting on the result.
Why choose this tool?
Separate element rows make it easier to check which faces have been counted and which parts of the formwork quote need additional allowances.
Before you use the result
Contact areas only. Props, reuse cycles, slab edges and support design are excluded.
Questions about Formwork Area Calculator
Does the area include props and support design?
No. Props, support loads, reuse cycles and framing arrangements are outside the contact area calculation.
