Except where specifically indicated or specified, no separate payment will be made for bolts, nuts, pins, washers, studs and strap hangers and the

17、 cost of such items must be included in the unit prices of items on which they are used. No separate payment will be made for the inspection of welds listed in paragraph NONDESTRUCTIVE EXAMINATION of this section.1.1.2 MeasurementMetalwork fabrication and machine work for which payment is not otherw

When 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 appro

20、ved as the basis for measurement.a. Computed Weights: Use the net calculated weights based on the dimensions indicated on the detail drawings for payment. Compute the weight of rolled shapes and plates on the basis of their nominal weights and dimensions. In calculating the net weights deduct all co

21、pes, cuts and open holes except rivet and bolt. Calculating additional weight for overweight allowance, protective coatings, allowance for milling, grip length of rivets and bolts and butt and groove welds is not allowed. Compute the weight of castings including fillets on the basis of the dimension

22、s shown on the detail drawings with deductions for all openings and cuts in the finished casting. Include within computed weights for fillet welds, rivets, bolts and cut washers in accordance with the following:ALLOWANCES FOR WEIGHT OF EQUAL-LEG FILLET WELDSLeg of weld in Kilograms per meterMillimet
