How do I determine optimum bay sizes when laying out a parking structure?
Efficiency and economy in precast concrete construction is driven by repetition, standardization and minimum number of pieces. Optimum bay sizes are most commonly based upon the width of the standard double tee module being used. A garage manufactured by a precaster utilizing 12′ wide double tees would optimally use 36′ or 48′ bays while a garage constructed with 15′ wide double tees would implement 30′ or 45′ bays. Precasters in the project region should be consulted to determine available modules.
