<br />15080 - 2/10 <br />A. Shop Drawings: Submit for approval the following: <br />1. The CONTRACTOR shall submit all deviations to the Work as shown or specified <br />for approval in accordance with Section 01300. <br />2. Tests: Submit description of pipe joint testing methods, procedures and <br />apparatus. Submit copies of all test reports. <br />3. Certificates: Submit certificates of compliance with referenced standards <br />indicated above. <br />4. As-Built Drawings: During progress of the Work, keep an up to date set of <br />drawings showing field and shop drawing modifications. The drawings shall <br />show all piping in plan and profile, with all reference dimensions and elevations <br />required for complete as-built drawings of the piping systems. Conform to the <br />requirements of Section 01720. As-Built shall clearly show the size, outside <br />diameter, manufacturer and type of pipe used in the directional drilling. <br /> <br />B. Experience Requirement: In accordance with Paragraph 1.02.A of this Section. <br />C. Pipe Material Calculations: The CONTRACTOR shall provide calculations <br />determining the maximum pulling force that may be anticipated during the pullback <br />operation to overcome theoretical frictional forces. The calculated pulling force will <br />not exceed the manufacturer's recommended yield tensile strength and factor of <br />safety for the proposed pipe material and fused joint. <br />D. Drilling Plan: CONTRACTOR shall submit a detailed narrative description of the <br />sequence of events that will be performed to install the specified pipe using <br />horizontal directional drilling. The plan shall indicate the location of existing utilities <br />as found by exploratory methods in the field. Plans shall also include the diameter of <br />the pilot hole, rig pulling capacity, torque, and mud pumping capabilities. Included <br />shall be a description of methods and precautions the CONTRACTOR proposes to <br />use to prevent exceeding the pipe manufacturer's approved safe yield tensile <br />strength during pullback. <br />E. Fusion Technician Qualification Certification: In accordance with Paragraph <br />3.02.C.4 of this Section. <br />F. Boring Path Report: The CONTRACTOR shall furnish a Bore Path Report for pipe <br />4” or larger to the ENGINEER within seven days of the completion of the bore path. <br />The report must include: <br />1 Location of project. <br />2 Name of person collecting data, including title, position and company name. <br />3 Investigation site location (Contract drawings station number or reference to a <br />permanent structure within the project right-of-way). <br />4 Identification of the detection method used. <br />5 Elevations and offset dimensions of the bore path. <br />6 Proposed directional drilling pipe path. <br /> <br />1.04 PRODUCT DELIVERY, STORAGE AND HANDLING <br />A.
