<br />15080 - 7/10 <br />no circumstances shall installed pipe be at a different elevation than 2-feet <br />from the horizontal alignment shown on the Drawings. <br />2. Should the completed directional drill pipeline alignment differ from the <br />Drawings such that additional/different fittings are necessary to join the <br />excavated pipe, then these shall be provided and installed at no additional <br />cost. <br />3. Entry and exit points shall be surveyed by experienced survey personnel <br />licensed in the State of Florida. <br />4. CONTRACTOR shall map the location of each pilot drill string joint to a <br />minimum horizontal and vertical scale of 1-inch equals 40-feet. The map shall <br />be posted in the CONTRACTOR'S office and at no cost. <br />5. Should the CONTRACTOR exceed the limits described above, a new pilot drill <br />shall be performed at the expense of the CONTRACTOR and at no cost. <br />6. Sump pits are required to contain drilling fluids if vacuum devices are not <br />operated throughout the drilling operation. <br />a. Within 48 hours of completing installation of the boring product, clean the <br />work site of all excess slurry or spoils. <br />b. The CONTRACTOR shall take responsibility for the removal and final <br />disposition of the excess slurry or spoils. <br />c. The CONTRACTOR shall ensure that the work site is restored to pre- <br />construction conditions. <br /> <br />C. HDPE Joining and Installation: <br />1. Sections of HDPE pipe shall be joined into continuous lengths on the job site <br />above ground. <br />2. Joining method shall be the butt joint heat fusion method and shall be <br />performed in accordance with the pipe manufacturer's recommendations and <br />by experienced personnel. <br />3. Butt fusion equipment used in the joining procedures shall be capable for <br />meeting all conditions recommended by the pipe manufacturer, including, but <br />not limited to, temperature requirements, alignment and 75 psi interfacial fusion <br />pressure. <br />4. Pipe and fitting joints shall be heat fused by a qualified fusion technician: <br />trained by an approved manufacturer's representative. In accordance with the <br />manufacturer's recommended fusion procedures. The CONTRACTOR shall <br />provide written certification from the pipe manufacturer for each fusion <br />technician employed on the Project. Training or requalification shall have been <br />obtained within the 12 months prior to the beginning of work <br />5. Each person making butt or socket fusion joints shall demonstrate proficiency <br />by making trial joints and destructively testing the trial fusions by bent strap <br />testing or ultra-sonic testing. Trial joints shall be allowed to cool completely <br />before testing, and shall not fail at the joint. During construction, the first fusion <br />of the day shall be a trial fusion, which shall be allowed to cool, and <br />destructively bent strap tested or ultra-sonically tested. If the fusion fails, <br />additional trial fusions shall be made and tested until successful fusions are <br />made, then that procedure shall be used for the balance of the day's <br />construction provided the procedure is within the limitations recommended by <br />the manufacturer.
