D-30 RFQ 20-10-01 Professional Engineering and Architectural Services for Pedestrian Bridge with Park Elements Across A1A at 174th St. CCNA D MAINTENANCE OF TRAFFIC Given the high volume of vehicles and pedestrians using Collins Avenue, safety of the traveling public and construction workers are paramount for this project. Not only must a safe work zone be guaranteed, but the public must confidently perceive it as such. The EAC Team will prepare a construction phasing and Maintenance of Traffic (MOT) sequence that makes safety considerations front-and-center. It is expected that the construction of the towers and pedestrian ramps on both sides of Collins Avenue can be constructed without impacting vehicular traffic. Appropriate measures to detour pedestrian traffic will be provided should sidewalks and paths in the park require closure. Construction of the elevator towers will be performed one at a time in order to keep one side of Collins Avenue unimpeded at all times, allowing for continuous pedestrian movement. Vehicles may not use Collins Avenue during the erection of the bridge structure which will require closure of the roadway. It is estimated that the erection of the bridge, ensuring proper bracing of all elements and confirming it is safely in place, may take up to three days - during which time vehicular detours will be provided for both the southbound and northbound directions of travel along Collins Avenue (see figure to the right). Pedestrian traffic at the bridge location will be limited to the east side of the roadway and diverted along the back perimeter of the park. Advance notification of roadway and sidewalk closures will be communicated to the local community well in advance of the actual closures and adequately communicated with temporary signs and digital message boards during the closure. The EAC Team will work closely with the City and the community to solicit feedback in order to develop an MOT plan that takes the needs and concerns of all parties into consideration. We will also coordinate and communicate the MOT plan and construction phasing, during design as well as during construction, with local law enforcement and emergency responders to develop routes that result in the lowest response times. Due to the nature of this project (specifically the need to erect the bridge elements), impacts to the traveling public cannot be completely eliminated, but the EAC Team will work closely with the community to mitigate against impacts to the furthest extent possible. ROADWAY SAFETY The EAC Team will comply with all safety vertical and horizontal clearances and setback requirements, while also designing a pedestrian bridge that will fit well in the context and become an attractive link between the neighborhood and the beach. We have proposed a construction sequence that minimizes impacts to the busy roadway.
