COMPUTED WEIGHT
The engineer will compute the weight of structural steel on the basis of the following assumptions as to density - kilograms per cubic meter (pounds per cubic foot):
|
Steel |
490 lb./ft.3 |
|
Cast Iron |
450 lb./ft.3 |
The weight of rolled shapes and plates will be computed on the basis of their nominal weight and dimensions as shown in the contract documents, deducting for copes and cuts.
The weight of welds will be included in the computed weight, assuming the weight of fillet welds to be used as follows:

* The weight of welds shown is 1.5 times theoretical weight.
The weight of heads, nuts, single washers, and threaded stick through of all high strength shop bolts shall be included in the computed weight on the basis of the following weight:
