Constructed in 1976, the parking structure at Ellis Hospital is a free-standing, four-story, cast-in-place concrete structure. The building is four bays wide with two interior bays sloped to serve as ramps between the levels. The structural system for the upper three levels is a 5½-inch-thick, post-tensioned, cast-in-place concrete slab.
Ryan Biggs Clark Davis performed an investigation and developed repair/maintenance priorities and budgets for the structure. The recommended $3 million repair program was phased over several years to allow continued use of the building.
Ryan Biggs Clark Davis was then retained to design repairs for several phases of the multi-phased repair program. The work included concrete repairs, coating repairs, and structural repairs to the post-tensioned tendons. For each phase, Ryan Biggs Clark Davis worked closely with the owner and contractor to develop travel lanes to allow full occupancy of the structure while the repairs were being performed.
