Steel Estimating Rule of Thumb

Steel Estimating Rule of Thumb

Steel Estimating Rule of Thumb

(OP)
I am estimating steel quantities for a preliminary design and only want +/- 25% accuracy.
Some engineers quote typical figures of xx kg/m^3 as a rough estimate or sanity check.
Does anyone know what typical figures would be for a steel framed crushing plant, and a steel framed process plant?

RE: Steel Estimating Rule of Thumb

Hi sdz,

For a steel framed process plant i usually take a value of 26 Kg/m3 when the equipments you have in the process plant are not very heavy.

Thanks busogu,
I ended up with 63 kg/m3 for a crushing station (including allowance for cleats & end plates). I would expect this type of structure to be on the heavy side so I can live with that.

RE: Steel Estimating Rule of Thumb

For roofs, I usually use about 5-6 psf and for floor systems (depending on loading) from 6 to 15 psf (typically 8 to 10).  Can convert using 1 m2 = 10.7 ft2 and 1 kg = 2.2 lbs.
