resulting from the excavation shall be transplanted, relocated, braced, shored or otherwise protected and preserved unless otherwise directed by the Engineer. 2) Delivery and Receiving Pipe — The pipe shall be delivered no more than 5 working days prior to joining and installation. Pipe and fittings may be stored in the right-of- way, adjacent to the boring path in the right-of-way only when they may be maintained outside the roadway "clear zone" as determined by F .D . O .T. standards. Appropriate unloading and handling equipment of adequate capacity must be used to unload the truck. Safe handling and operating procedures must be observed. Pipe and fittings must not be rolled or pushed off the truck. When using a forklift, or forklift attachments on equipment such as articulated loaders or bucket loaders, lifting capacity must be adequate at the load center on the forks. Forklift equipment must be rated for the maximum lifting capacity at a distance from the back of the forks . Lifting equipment such as cranes, extension boom cranes, and side boom tractors, should be hooked to wide web choker slings that are secured around the load. Only wide web slings should be used. Wire rope slings and chains can damage components and shall not be used. Spreader bars shall be used when lifting pipe longer than 20' . Individual pipes may be stacked in rows . Pipes shall be laid straight, not crossing over or entangled with each other. The base row must be blocked to prevent sideways movement or shifting. The pipe sections shall be stacked no higher than 2 rows. B . Joining, Pive and Stub-End 1 ) Joining and stringing of the pipe shall be accomplished in one continuous operation. The joining shall begin promptly at the beginning of the work day and continue until completed. Pipe joining and directional boring shall be the only on-site operation allowed to continue beyond 5 : 00 P.M. The CONTRACTOR shall have all traffic control devices, lane closures and signage in place and ready for use prior to start- up . 2) Joining shall be accomplished using a hydraulically operated, microprocessor controlled heat fusing machine, specifically designed to handle the project pipe O.D . The operator shall have had a minimum 3 years experience in the process of operating H.D.P.E. butt-fusion machines capable of joining at least 8-inch diameter pipe. 3 ) Joining shall generally follow these procedures : a) Securing Each component that is to be fused must be held in position so that it will not move unless a clamping device moves it. 02400 — Directional Bore Crossings 02400 - 5
