FLO <br />H <br />TO: <br />VIA: <br />FROM: <br />DATE: <br />RE: <br />City of Sunny Isles Beach <br />18070 Collins Avenue <br />Sunny Isles Beach, Florida 33160 <br />(305) 947 -0606 City Hall <br />(305) 949 -3113 Fax <br />MEMORANDUM <br />The Honorable Mayor and City Commission <br />Christopher J. Russo, City Manager <br />Bill Evans, Assistant City Manager <br />9/18/2014 <br />A Resolution Ratifying an Agreement with PAC Comm Inc. for <br />Emergency Repair of the Seawall at Intracoastal Park <br />RECOMMENDATION: <br />Staff recommends City Commission approve the Resolution. <br />REASONS: <br />The first week of August, approximately 140 linear feet the seawall at the far <br />south end of the Intracoastal Park abruptly failed by canting outward and <br />sloughed wall backfill into newly created void. To avoid complete failure of the <br />seawall, the City immediately contacted PAC Comm, Inc., an experienced and <br />well qualified marine contractor, who was deployed in Surfside at the time. At <br />City request, PAC Comm, Inc. reported to the site to assess initial damage and <br />develop a plan to repair or replace the wall as quickly as possible; they have <br />since mobilized onsite and commenced repair /replacement. In addition to <br />repairing the obvious failed section(s) of the seawall, additional field <br />investigations were performed to evaluate the structural integrity of remaining <br />sections of the seawall that had not visibly failed. These field investigations <br />revealed that the wall was constructed with tie -backs into the park as was <br />common construction practice at the time of original construction. Most <br />connections had deteriorated or failed due to age and field conditions. Given this <br />discovery, failure of additional portions of the wall are a near certainty in the <br />forseeable future. The repairs have commenced at the south end of the park and <br />will continue to the maximum limits approved by Miami Dade County Department <br />of Regulatory and Economic Resources (formally DERM) under an emergency <br />permit issued for the repair work. <br />In order to preserve the seawall to the greatest extent possible and avoid its <br />failure in additional areas, the City was unwilling to delay the project. gkgrAAAWION <br />an existing contract in place in Surfside, given their knowledge of theatsfte /a 1d <br />
