Hi:

for structural steel works, I have used (as estimation and confirmed with m-h usage) from 90 to 120 m-h/ton, from classification, installation, alignment, bolting, etc. Consumption for machinery (crane, manlift) is not considered in this range.

Considers the type of structure (heay, ligth, medium, etc), classified as per kg/m.

regards

Hi Suaila, difficult, but as a guide I suggest crew of 4-5 men and 25 pieces of steel with a weight of 25 kilos within a 10 day workday. Regards Jan
