CITY OF SUNNY ISLES BEACH SECTION 01000 - 1 <br />SUMMARY OF WORK <br />SECTION 01000 <br />SUMMARY OF WORK <br />PART 1 - GENERAL <br />1.1 WORK COVERED BY CONTRACT DOCUMENTS <br />The work described in these specifications is for the maintenance and rehabilitation of twenty <br />(20) existing storm water gravity disposal wells owned by the City of Sunny Isles Beach <br />(OWNER), located on Central Island neighborhood in Sunny Isles Beach, Florida. In addition, <br />there is some minor ancillary maintenance work related to several drainage outfall pipes that <br />may require attention. <br />On 1/29/18, inspections were performed at four (4) wells located along North Bay Road that <br />are identified as W-2, W-3, W-15 and W-18 on the attached Exhibits (see the Appendix). All <br />of these wells revealed debris and extensive amounts of sludge in the concrete well <br />structures and the well casings. A summary of findings is provided. <br />The OWNER may elect to rehabilitate some or all of the wells as the OWNER sees fit. The <br />OWNER will determine the wells that are to be rehabilitated and the order in which <br />rehabilitation is to take place. The well location maps and a construction details table are <br />provided in the Appendix at the end of these specifications. The CONTRACTOR shall <br />perform all work in accordance with specification sections provided in the contract <br />documents. <br />Examples of typical scope of work for these wells are described below. The actual scope will <br />vary; this is only provided to give insight as to the nature of the anticipated work. <br />Mobilize to each well site, remove access lid, perform visual of the well structure and <br />arrange for a “before” downhole video to determine the extent of sludge buildup in the <br />well structure and the well casing. <br />Arrange to remove the existing steel grate/screen on the top of the well casing within the <br />well structure. Clean/remove all debris and vegetative growth within the well structure. <br />Pending the results of the “before” video, if warranted, clean out (a) all sludge in the <br />concrete well structure and (b) the open hole casing using the reverse air method, <br />develop well using airlift/jet vac. <br />Perform “after” video to confirm that the cleanout procedure was successful and the steel <br />well casing’s integrity has been maintained. <br />If the wall of the casing has been compromised, arrange for the installation of a 20” PVC <br />casing inside the existing casing (assumed to be 24” per as-built drawings).
