Library Lane Parking Structure
- Oct 5, 2012
In July 2012, a 711-space, four-story garage was opened in Ann Arbor, Michigan. This library is part of a redevelopment project that could also accommodate a future 20-story building.
In order to make the facility comfortable and user friendly, the designers incorporated open stairways, glass side walls on the elevators, structural bracing to maximize visibility, large ceiling heights, long-span construction and bright white lighting.
The structure uses a number of sustainable features including being constructed from highly durable materials. The concrete contained calcium nitrite along with 25% fly ash and 15% slag. In addition the concrete had to provide a rapid strength gain and consistent air content, a predictable setting time and good consolidation at column girder intersections and PT anchorages. The material was also pumped up to 600 ft. Epoxy-coated reinforcing steel was also extensively used. The building uses rainwater that is detained in a 305,000 gal tank at the lowest level of the structure.
