How to calculate approximate formwork and steel bars by total volume of concrete works? I want to check my work process?

a)      Formwork Calculation:

For formwork calculate the area of formwork separately for different structural members such as column, beams, slab, foundation, concrete walls etc. then apply unit area rates from schedule rates of your country or take a lump sum amount for overall form of structure but it must be kept in mind that rates of formwork for different structures is different depending on usage of formwork, material used, height etc.

 

b)      Steel calculation:

Calculate weight of steel bars used in unit volume of concrete then multiply it overall volume of concrete and by this way you will get results quickly but in case of complex layout of distribution of steel bars and If you want more accurate result then calculate overall length of all bars and multiply with density of bars.

 

I am using these methods, please inform me what process you are adopting?

Shah hussain I didn't understand your method .plz told me again, what is overall volume of concrete? I clculate the volume of concrete already and you say weight of bar used in volume of concrete and then multiply by overall volume of concrete. You telling me again, please
