The Suspended Floor Estimating Calculator is used to calculate the Labour, Materials and Plant items and costs involved in constructing timber suspended floors for upper floors (i. e. not the ground floor).

The Suspended Floor Estimating Calculator calculates the following items:

  • Floor joists
  • Floor surface
  • Insulation
  • Plastering
  • Decorating
  • Plus all labour associated with the above

All of the items required in a suspended floor are specified from the Specification.


  • You should also check all the pre-specified items in the Calculated Resources tab, in particular the red highlighted “critical items” before accepting the output.
  • To estimate a ground floor suspended floor, use the Suspended Timber Ground Floor Estimating Calculator.
