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.

List of typical steel amounts used in different kind of structures and elements (please note that these are average values, in reality there is variance). All the quantities are shown per m3 of concrete. Typical density of concrete is approximately 2400 kg /m3. Tendon* = high strength low alloy steel, typically used for instance in pre-stressed concrete elements, this steel grade is likely to contain more virgin steel Rebar steel* = basic steel used for concrete reinforcement.
  • Pre-stressed concrete beam: 30 kg of tendon and 30 kg of normal rebar steel
  • Reinforced concrete beam: 100 kg of normal rebar steel
  • Column: 100 kg of normal rebar steel
  • Hollow core concrete slab**: 10 kg tendon
  • Wall, internal element (for instance 180 mm): 35 kg of normal rebar steel
  • Wall, external layer (for instance 70 mm): 80 kg of normal rebar steel or stainless steel
  • Balcony (for instance 260 mm): 125 kg of normal rebar steel

* In Finnish: Tendon = jänneteräs, Basic rebar steel = harjateräs ** If you’ll need to estimate this please make sure you’ll have the right amount of concrete taking into account the wholes. Usually, for hollow core concrete slab it is better to use an EPD that includes reinforcement as they usually do.
