§ 720S.9. Payment
Structural steel for main members will be paid for at the unit price bid per pound for "Structural Steel", "Structural Steel-HS", "Structural Steel-XHS", or such other classification(s) of metal indicated.
Shipping invoice or acceptance slip weights will not be used as basis for payment.
Payment will be made based on the quantity indicated, except as may be modified by the following:
A.
Either party to the contract may request an adjustment of the quantities indicated (by each separate bid item), if the weights calculated in accordance with this specification vary from those indicated by more than the following:
1.
Over 500 tons - 0.5 percent.
2.
50 tons through 500 tons - 1 percent.
3.
Less than 50 tons - 1.5 percent.
When adjustment is required, the Contractor shall furnish the Engineer or designated representative three sets of shop bills showing the calculated weights of all parts of the structure. The weights shall be computed from the approved shop drawings, except as noted above. When this quantity is certified correct by the Engineer or designated representative, it will become the revised plan quantity. Quantities revised in this manner will not be subject to the provisions of the "General Conditions".
B.
When quantities are revised by a change in design, the plan quantity will be increased or decreased by the amount involved in the design change. Quantities revised in this manner will be subject to the provisions of the "General Conditions".
The unit bid price(s) shall include full compensation for furnishing all materials and for all fabrication, shopwork, transportation, erection, paint, painting, galvanizing, and for furnishing all equipment, tools, labor, and incidentals necessary to complete the work.
Payment, when included as a contract pay item, will be made under:
Pay Item No. 720S-A: Structural Steel Per Pound. Pay Item No. 720S-B: Structural Steel-HS Per Pound. Pay Item No. 720S-C: Structural Steel-XHS Per Pound. End
