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.

## Inputs and controls

* Measurement unit: Feet; Metres; Inches; Centimetres; Millimetres
* Shuttering rate (PKR / sq ft). Allowed range: 0 to 1000000000. Optional. Enter your own supplier quote.
* Reference
* Element: Column, four sides; Beam, sides and soffit; Slab soffit
* Length / height. Allowed range: 0.001 to 100000
* Width. Allowed range: 0.001 to 100000
* Depth. Allowed range: 0.001 to 100000
* Quantity. Allowed range: 1 to 10000

## How to use

* 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 use 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 relying on the result

Contact areas only. Props, reuse cycles, slab edges and support design are excluded.


## Tool limitations

Contact areas only. Props, reuse cycles, slab edges and support design are excluded.

## Questions

### Does the area include props and support design?

No. Props, support loads, reuse cycles and framing arrangements are outside the contact area calculation.

### What should I check before using Formwork Area Calculator?

Check Measurement unit, Shuttering rate, Reference and Element. Use the exact units shown beside the controls and replace any example values with your own inputs.
