For a feasibility study, your Insitu Concrete breakdown is 15% labour, 80% materials and 5% fixed costs,
and your Formwork breakdown is 80% labour, 20% materials and 0% fixed costs.
Constants assume five uses of formwork.
Where the number of uses is less, the constants should be adjusted by the percentage shown:
Rates include fabrication, fixing in place and striking.
