The structure contains approximately 618 parking spaces on three levels. The garage is post-tensioned, cast-in-place concrete. The west and north walls are virtually solid to mitigate noise and light to the neighboring apartments. The upper barrier panels are a minimum of eight feet tall to mitigate sound and light emission. A decorative mansard required an inventive torsion-tube support to eliminate interior columns that could interfere with the parking. The conceptual design was created by MBA and then refined and implemented by BJG. The garage occupies nearly all of it’s site and posed difficult staging for the contractor.
