Ensure that each shipment of products to the job site includes a list of products <br />shipped and the required written certification statement for each product. Provide this list <br />..., and certification(s) to the Engineer. <br />. <br /> <br />II <br /> <br />641-2 Materials. <br />Meet the following requirements: <br />Portland Cement Concrete * ........ Section 346 * Class V Special <br /> <br />. <br /> <br />.., <br />. <br /> <br />641-3 Concrete Pole Construction. <br />Construct concrete poles in accordance with Section 450. Assume responsibility for <br />performance of all quality control testing and inspections required by Sections 346 and <br />450, however; the PCI personnel and plant certifications are not required. <br /> <br />.., <br />. <br /> <br />n <br /> <br />641-4 Installation Requirements. <br />641-4.1 General: Furnish poles of the type and length shown on the plans. Provide <br />catenary cable of the size shown on the plans. Ground poles in accordance with <br />Section 620. Install span wire assemblies in accordance with Section 634. <br />Do not consider the poles acceptable for use if the camber of the pole, <br />measured as the maximum deviation between the centerline of the pole and a straight line <br />connecting the centroids of the cross-sections at each end of the pole, is greater than the <br />total pole length in inches [millimeters] divided by 140]. <br />641-4.2 Footings: Provide footings 3 feet 6 inches [1 m] in diameter and of the <br />depth specified in the plans for strain poles used for span wire support of traffic signals. <br />Provide footings for all other pole applications as specified in the plans. Construct the <br />footings with Class I concrete as specified in Section 347. <br />For the excavation and backfill of the footing, meet the requirements <br />specified in 125-4 and 125-8.2 with the exception of the backfill density. In lieu of the <br />requirements for obtaining the specified density, the Contractor may hand tamp the backfill <br />in 4 inches [100 mm] maximum layers or machine tamp the backfill in 6 inches [150 mm] <br />maximum layers. When performing such operations, ensure that the material is neither dry <br />nor saturated. The Contractor may backfill with concrete. <br />Use forms, when required, meeting the requirements of 700-7.3. If the <br />footing is cast in an oversize hole, place the concrete in the top 6 inches [150 mm] in a <br />form. Trowel all exposed surfaces to a smooth finish. <br />641-4.3 Orientation of Poles: For poles supporting one catenary wire, orient the <br />pole so that the load face is perpendicular to the catenary wire. For poles supporting two <br />catenary wires, orient the pole so that the load face is perpendicular to a line bisecting the <br />angle between the two catenary wires. <br /> <br />., <br />. <br /> <br />., <br />. <br /> <br />1"'1 <br />. <br /> <br />. <br /> <br />r"1 <br /> <br />. <br /> <br />, <br />. <br /> <br />.., <br /> <br />. <br /> <br />,.., <br /> <br />. <br /> <br />..., <br /> <br />641-5 Method of Measurement. <br />641-5.1 General: Measurement for payment will be In accordance with the <br />following work tasks. <br /> <br />...1 <br /> <br />..., <br /> <br />. <br /> <br />..., <br /> <br />09/09 <br /> <br />01000-148 <br /> <br />03-4122.F <br /> <br />. <br />
