CTA Project No. 19-0035-001-01 16110-7 Golden Shores Street Lighting <br />October 12, 2020 SIB Bid No. 20-09-01 <br />3. Concrete or Brick: Expansion shields, or threaded studs driven in by powder charge, <br />with lock washers and nuts. <br />4. Steelwork: Machine screws. <br />D. Nails or wooden plugs inserted in concrete or masonry for attaching raceway not <br />permitted. Do not weld raceways or pipe straps to steel structures. Do not use wire in <br />lieu of straps or hangers. <br />3.06 BENDS <br />A. Install concealed raceways with a minimum of bends in the shortest practical distance. <br />B. Make bends and offsets of longest practica l radius. <br />C. Install with symmetrical bends or cast metal fittings. <br />D. Avoid field-made bends and offsets, but where necessary, make with acceptable hickey <br />or bending machine. Do not heat metal raceways to facilitate bending. <br />E. Make bends in parallel or banked runs from same center or centerline with same radius <br />so that bends are parallel. <br />F. Factory elbows may be installed in parallel or banked raceways if there is change in <br />plane of run, and raceways are same size. <br />G. PVC Conduit: <br />1. Bends 30-Degree and Larger: Provide factory-made elbows. <br />2. 90-Degree Bends: Provide rigid steel elbows. <br />3. Use manufacturer's recommended method for forming smaller bends. <br />H. Flexible Conduit: Do not make bends that exceed allowable conductor bending radius of <br />cable to be installed or that significantly restricts conduit flexibility. <br />3.07 EXPANSION/DEFLECTION FITTINGS <br />A. Provide on all raceways at all structural expansion joints, and in long tangential runs. <br />B. Provide expansion/deflection joints for 5 0 degrees F maximum temperature variation. <br />C. Install in accordance with manufacturer's instructions. <br />3.08 PVC CONDUIT <br />A. Solvent Welding: <br />1. Provide manufacturer recommended solvent; apply to all joints. <br />2. Install such that joint is watertight. <br />B. Adapters: <br />1. PVC to Metallic Fittings: PVC terminal type. <br />2. PVC to Rigid Metal Conduit or IMC: PVC female adapter. <br />C. Belied-End Conduit: Bevel the unbelled end of the joint prior to joining. <br />3.09 WIREWAYS <br />A. Install in accordance with manufacturer's instructions. <br />B. Locate with cover on accessible vertical face of wireway, unless otherwise shown.
