Average Material Quantities

Average material quantities in typical structures

You can refer to the table below for average material quantities in typical structures.  

These estimations are recommended to use if:

• Your BIM model includes composite elements which consist of more than one material, but you have no additional info of specific material quantities in the element,
• You know the area of your construction element, but not a specific quantity of the materials.

For average quantities of reinforcement steel in concrete, please check here: Rebar in concrete
