652 WWR, when required, shall be placed as shown on the plans or as otherwise directed. The sheets shall overlap sufficiently to maintain uniform strength and shall be securely fastened at lapped ends and edge s. The laps shall be no less than one mesh in width. Spiral reinforcement, consisting of evenly spaced continuous spirals, shall be held firmly in place by attachment to vertical reinforcement. Th e spirals shall be held true 110 to line by vertical spacers. Anchorage for sp iral reinforcement shall be provided with 1 1/2 extra turns of the spiral rod or wire at each end of the spiral un it. Splices in spiral rods or wire shall be made with a lap of 1 1/2 turns. Threaded tie bar assemblies may be used in lieu of spliced reinforcing bars shown on the plans. Threaded tie bar assemblies shall achieve the minimum strength in accordance with 910.01(b)2. The Contractor sh all coat any exposed part of threaded bar assemblies in accordance with 910.01(b)2.
703.07 Method of Measurement 120
Reinforcing bars will be measured by the pound based on the theoretical number of pounds complete in place as shown on the plans or placed as ordered. The quantities of materials furnished and placed shall be based upon the calculated weights of the reinforcing bars actually pl aced in accordance w ith these specifications. The weights calculated shall be based upon the following table: Bar Designation No. Weight per linear foot, pounds Bar Designation No. Weight per linear foot, pounds 1/4 in. 0.167 8 2.670 3 0.376 9 3.400 4 0.668 10 4.303 5 1.043 11 5.313 6 1.502 14 7.65 7 2.044 18 13.60 Threaded tie bar assemblies will be measured by the number of assemblies placed. WWR will not be measured. 130
703.08 Basis of Payment
The accepted quantities of reinforcing bars will be paid for at the contract price per pound, complete in place. If the substitution of reinforcing bars larger than those specified is allowed, payment will be made for only that weight which would be required if the specified bars had been used. 703.07 653 If the use of reinforcing bar lengths shorter than those shown on the plans is 140 allowed for convenience in transporting or placing the bars, payment will be based on the weight of the lengths shown on the plans. Payment for threaded tie bar assemblies will be at the contract unit price per each, complete in place. If epoxy coating is speci fied, payment for the assemblies will be at the contract unit price per each for thr eaded tie bar assembly, epoxy coated. Payment will be made under: Pay Item Pay Unit Symbol 150 Reinforcing Bars ........................................................................
