Giordano and Associates, Inc. provide a work authorization to address the safety concerns for vehicular and pedestrian traffic for the at -grade approach. The signalization was required due to the restricted available right of way or easement width at the south landing which only accommodate one way bi- directional traffic and pedestrians. Work Authorization No. 145 Increased Scope The original contract for the bridge design did not include a detailed construction cost analysis as a part of design phase services. This Work Authorization performed a complete bid take off, analysis and constructability review by a licensed and well known marine contractor. Given the complexity of this project, this detailed review provides for accurate and updated cost figures, investigate for and identify potential areas for value engineering, define construction methods to ensure permits and easements are obtained properly, and result in potential bidders submitting Requests for Information and areas of potential change orders prior to bid opening. This allowed the design team to make adjustments to the plans prior to bid opening, which can result in a large savings to the City. Work Authorization No. 149 Increased Scope The original contract and subsequent amendment for the bridge design did not include hydrographic surveying services needed to elevate possible mitigation areas within the City. Suitability if seagrass mitigation areas are generally a function of water depth and water quality. This work was authorized to obtain needed data to determine if either the Atlantic Isles lagoon or the eastern terminus of the canal between Bayview Drive and Kings Point Drive west of Collins Avenue are suitable candidates for seagrass mitigation arrears. Work Authorization No. 162 Increased Scope This Work Authorization will allow Calvin, Giordano and Associates, Inc and associated subconsultants to provide a final design and perform final permitting services for the completion of the Pedestrian and Emergency Vehicular Bridge. This work specifically includes incorporating ADA compliance modifications, providing for the relocation of an existing FPL transformer at Porta Bellagio that is in direct conflict with the south landing of the bridge, additional local permitting from Miami Dade County Fire Department, Miami Dade Environmental Resources Management (DERM), and City Building and Public Works Permits. It is expected that this work authorization is sufficient to complete design side technical and permitting services to accommodate advertisement of the project and subsequent award. The cost of this work is in an amount not to exceed $304,095.75. ATTACHMENTS: • Resolution • Agreement Agenda Item No. IOM Date 2/20/2014 234
