The Great Lakes Science Center is one of America’s largest interactive science museums.
In addition, Cleveland’s North Coast Harbor includes the Rock and Roll Hall of Fame &
Museum and Cleveland Browns Stadium.
The 500-stall post-tensioned parking structure proudly serves all three attractions. The
structure utilizes 6 inch thick one-way slabs and 36 inch deep one-way beam (spanning
62-feet) supported by cast-in-place concrete columns spaced 25 1/2-feet apart. Since
portions of the garage are below grade, cast-in-place concrete retaining walls occur on two
sides which retain the lateral earth pressure.
The “green” roof plaza structure supports 24- to 36-inches of soil. The plaza serves as
exterior exhibits for the Science Center during summer months. Lastly, the garage structure
is supported by 100-ton augercast concrete pile groups located below each column and
the continuous retaining wall footings.
