Before revision: A good example of specified loads would be the following simplified floor to ceiling sandwich load table (based on the National Building Code of Canada standards): Floor Finish (Terrazzo) per 10 mm thickness = 0.24 kN/m^2 Reinforced Concrete per 10 mm thickness = 0.24 kN/m^2 Mechanical Services = 0.35 kN/m^2 Electrical Services = 0.10 kN/m^2 Floor Area (110 mm thickness) = 8 m^2 Total Dead Load = (0.24 + 11*0.24 + 0.35 + 0.10)*8 = 26.64 kN In order to design to these loads, one would need to convert them to design loads by applying Load factors or, more generally, a form of safety factors to them.
