EAC Consulting, Inc. eacconsult.com City of Sunny Isles Beach • RFQ 19-11-01 • Professional Engineering and Architectural Services for Pedestrian Bridge with Park Elements Across A1A at 174th St. PROJECT SCOPE AND METHOD OF APPROACH Our Project Team is ready to refine and complete the 174th Street and Collins Avenue Bridge Park selected design concept. We have sensibly studied the Sunny Isles Pedestrian Overpass Planning Study and the 2016 Transportation Master Plan to fully understand the project scope. The project is in one of the most heavily traveled intersections by pedestrians and vehicles within the City of Sunny Isles Beach, and the concept design will be an open and elevated bridge park over the south side of the intersection, traveling east and west, to accommodate for vehicular improvements at the surface level and to take the pedestrians to an elevated plane for an enhanced crossing experience reflected as an extension of the Samson Oceanfront Park. Our Project Team provides a fresh approach in order to identify potential refinements to the concept design; our experience on pedestrian bridges allows project familiarity that will improve the concept design and maximize efficiency and cost effectiveness. Our portfolio of pedestrian bridge projects is indicative of our familiarity with infrastructure works within pedestrian bridge facilities locally and nationally. The EAC Project Team brings an in-depth understanding of the needs associated with this project. The scope of work includes the design of a pedestrian link that will become an extension of the adjacent Samson Oceanfront Park, creating a “destination experience.” The new link will be green and sustainable and will incorporate the use of native plants to create a buffer for pedestrians crossing Collins Avenue. It will be designed as a plaza, with landscaping, creating an elevated park. The connection will be fully American with Disabilities Act (ADA) accessible with stairs and elevators, that will be provided on the east and west approaches. It is our mission to design a pedestrian green crossing that is visually attractive, structurally efficient and cost effective. Proposed Bridge Structure The proposed bridge will have a main span of 165 feet with a cantilevered span providing seating for pedestrians. Bridge width will vary from 49 feet to 61 feet, with a minimum vertical clearance of 21 feet. Florida-U Beams (72 inch) can be utilized to support the pedestrian loads and dead loads including soils, plants, glass walls and glass railings, and miscellaneous items. The U-beams will be precast and erected at night with no traffic under the beams - for public safety and ease of erection. The beams will be securely connected to the supporting piers to ensure stability of the structure immediately after erection. To minimize impact to local traffic, precast decks can be used, integrating with the U-beams, for an integral bridge structure. Both and bridge layout and pier structures will have the architectural and park features desired by the city. Foundation systems like Auger Cast In Place (ACIP) piles, driven piles, and drilled shafts can be considered. Driven piles will create vibration and noise and have impact to the local activities. ACIP piles and drilled shafts will eliminate these concerns. Drilled shafts also have the least footprint, which may be critical to minimize impact to local traffic during construction.
