measurement of complicated shapes can be determined more readily by scale
weights per fabricated piece, cast piece or assembly the use of certified
scale weights will be approved as the basis for measurement.]
a. [Computed Weights: Weights for payment shall be the net calculated
weights based on the dimensions indicated on the detail drawings. The
weight of rolled shapes and plates shall be computed on the basis of
their nominal weights and dimensions. In calculating the net weights
all copes, cuts and open holes except rivet and bolt holes shall be
deducted. No additional weight shall be calculated for overweight
allowance, protective coatings, allowance for milling, grip length of
rivets and bolts and butt and groove welds. The weight of castings
including fillets shall be computed on the basis of the dimensions
shown on the detail drawings with deductions for all openings and cuts
in the finished casting. Computed weights for fillet welds, rivets,
bolts and cut washers shall be included in accordance with the
following:
