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