The Scope of Work for the State-Of-The-Art Mobility Hub may consist of the following: The Mobility Hub will be a mixed-use building that will host multiple transportation and mobility activities for people visiting, living, and working in Coral Gables. The City of Coral Gables is envisioning this structure to have a lifespan of 75 years. Due to the fast-changing pace of transportation and mobility technology, this building will need to be designed to be adaptable during its lifespan. The following scope narrative and conceptual study, prepared by the City’s Parking Consultant, provides a sample conceptual approach that defines the Project’s program. The ground level of the Mobility Hub will most likely host the mobility related program components, including an internal drive-thru lane for ride sharing services to pick-up and drop-off users and have accessibility to other mobility uses at grade. Due to Andalusia Avenue being one way eastbound, we have located the entry/exit lanes to the parking levels on the west side of the building with the exit lane for the drive-thru lane on the west side of the building to minimize vehicular conflicts. The entry to the drive-thru lane is located on the east side of the building to minimize vehicle conflicts and provide a clean entry portal for those utilizing the many mobility options. The sidewalk on the north side of Andalusia Avenue will be dedicated as drop-off and pick-up areas for City Trolleys and other larger vehicles. The ground level will provide retail/flex-use space, bicycle storage, dockless vehicle parking, bike share docking stations, a wi-fi lounge, e-Commerce Logistics for drone package deliveries and pop-up coffee shops. Back of house (MEP) support spaces will also be located on the ground level. A speed ramp will take vehicles up to the first supported level to maximize the space for other ground level uses. A pedestrian connection on the ground level in the north-south direction will connect to a new Paseo on the north side of the alley that will allow users direct access to Miracle Mile from the building. Glass-backed elevators, facing Andalusia Avenue will be utilized to enhance passive security. A second pair of elevators will serve the e-Commerce logistics with access to the rooftop for drone delivery. Initially, the first supported level will be reserved for Electric Vehicles (EV), with charging stations on all spaces. As the need for additional EV charging stations grows, additional levels will be convertible to be exclusive for EV. Provisions and upgrading of the electrical system will be needed to accommodate for the future expansion of the EV charging infrastructure. These provisions shall include running empty conduit to the future location of EV charging stations and additional space for transformers and other electrical equipment in the electrical room. This first supported level will be 25’-0” above the ground level to provide ample headroom for the ground level program uses and access to the pedestrian path connecting to the Paseo and eventually Miracle Mile. The intermediate levels between the ground level and the rooftop will serve as self-parking levels when the building is opened. These levels have been designed to accommodate self-driving vehicles in the future since the garage consists of long span construction. The ramp layout of these park-on levels will be a double threaded helix ramping system, with one-way traffic flow and two (2) doubleloaded bays, utilizing angled parking. The footprint of the park-on levels will overhang 5’-0” to the sidewalk on the south side of the property as well as 5’-0” on the alley side, on the north side. This will increase the efficient depth of the property from 100’-0 to 110’-0” to accommodate the two (2) double-loaded parking bays. The self-parking portion of the garage will roughly yield between 750- 800 spaces. The parking bays will have columns on the perimeter to improve maneuvering and visibility. The concept was developed with a cast in place post-tensioned structure in mind for the long span parking bays and for the expected lifespan of the building. The floor-to-floor height on the intermediate levels is 12’-0” for improved natural ventilation, distribution of natural light and to improve passive security. Self-driving vehicles will be able to park closer together so that when the garage is converted to 100% self-driving vehicles, the parking capacity may increase to approximately 1,050 spaces, using the same floor area. The parking portion of the building will be designed as an open parking garage with natural ventilation. The top level of the mixed-use building will be an active rooftop with open air uses for the public: potentially including landscaped areas, venue space, café/restaurant(s), lounging areas and/or areas to practice sports. The final design will need to consider the egress needs for public assembly. The City also wants to consider a heliport on the top level of the building.
