Walker was prime designer for the expansion of the OhioHealth Riverside Methodist Hospital Red Garage. The expansion created 600 additional spaces with a 5-level horizontal and 1-level vertical expansion. The expanded garage has a total capacity of 1,633 spaces separated between employees and the public. The structure is cast-in-place post-tension concrete with a precast facade. There is a separate ramping system for the different user groups of the structure.
In addition to prime design, Walker’s services included parking planning, functional design, structural/mechanical/electrical engineering, and PARCS/signage consulting.
The decision to expand vertically and horizontally was determined through a master parking planning exercise and feasibility study based on the growth of facilities on campus. The vertical expansion minimized the amount of additional sites required to add spaces. The horizontal expansion was a compromise to add additional spaces with flat floor parking in a compact footprint. It also encompasses a new emergency generator facility on the ground floor.
