<br />3.02 UTILITIES <br /> <br />A. Furnish equipment, materials, and labor required to complete excavating, <br />trenching and backfilling for utilities, including dewatering, shoring, bracing, <br />utility bed compacting, protecting slabs, restoration of surfaces, and disposing of <br />surplus materials as identified in the Drawings and/or Specifications. <br /> <br />B. Length of trench to be excavated ahead of pipelaying shall be limited to <br />sufficient trench for one day's pipe laying operation. <br /> <br />C. Where existing utilities are indicated, or their presence is suspected, employ <br />appropriate detection methods to locate the utilities. <br /> <br />D. Excavation in the vicinity of utilities shall be carefully carried out to prevent <br />damage to the existing utilities. <br /> <br />E. Excavation within 12-inches of existing utility shall be by hand. <br /> <br />3.03 TRENCH EXCAVATION <br /> <br />A. Where trenches are to be cut in pavement, the pavement cut shall be made <br />ahead of the excavation, leaving a uniform edge with minimum disturbance of <br />the remaining pavement. <br /> <br />B. Pavement pieces 6-inches and larger are not to be mixed with other excavated <br />material, but are to be disposed of away from the work site before the remainder <br />of the excavation is made. <br /> <br />C. Minimum width of the trench shall be equal to the outside diameter of the pipe at <br />the joint plus 12-inches on each side. <br /> <br />D. Maximum trench width shall not exceed the nominal diameter plus 2-feet. <br /> <br />E. Trench walls shall be vertical, however, for large diameter piping, or where deep <br />trenching is required, sloped sides may be permitted subject to the approval of <br />the ENGINEER. <br /> <br />3.04 BEDDING <br /> <br />A. The pipe bed shall be adequately graded and shaped such that the pipe will be <br />in continuous contact for its full length and the bottom 1/2 of its circumference, <br />spaces for joints, fittings, manholes and pump stations shall be excavated with <br />space to install joint couplings and other connecting devices. <br /> <br />B. Bell holes shall be excavated to the necessary size at each joint or coupling to <br />eliminate point bearing. <br /> <br />City of Sunny Isles Beach <br />NE 174th Street Roadway Improvements <br />02300 - 7 Earthwork <br />14-1758 / 09-19-2014 <br />
