D-28 <br />RFQ 20-10-01 Professional Engineering and Architectural Services for Pedestrian Bridge with Park Elements Across A1A at 174th St. CCNA D <br />CONSTRUCTION SEQUENCE <br />We have evaluated a Construction Phasing Sequence to provide efficiency and safety for the bridge construction: <br />Phase 1 <br />Phase 2 <br />Phase 1: Install Temporary Barrier Wall and Close Sidewalk on West Side, Redirect Pedestrian Traffic to the East Side sidewalk, Build <br />Foundation, Pier and Drainage for the West Side. <br />Phase 2: Install Temporary Barrier Wall and Close Sidewalk on East Side, Redirect Pedestrian Traffic to the West Side sidewalk, Build <br />Foundation, Pier and Drainage for the East Side. Install Temporary Signal and Lighting. <br />The EAC Team has evaluated the beam transportation method with an AutoTURN analysis to investigate if the beam delivery from the <br />183rd Street and Collins Avenue intersection is attainable. The analysis includes vehicle access checks, clearances, vehicle tracking, <br />and path maneuvers. As a result of the analysis, the overall length of the beam delivery truck (including the U-beams) will be able to <br />make the turn at the 183rd Street and Collins Avenue intersection without any major impacts. <br />Figure 12: Beam Delivery Truck AutoTurn Analysis
