This new car dealership consists of a two story, 41,000 SF showroom with a four story, 168,000 square foot parking structure behind. Due to poor soils, both buildings' foundations were constructed over ram aggregate piers that improved bearing pressures and alleviated settlement concerns. The site's proximity to the San Andreas Fault (<0.5 km) lead to large anticipated ground motions and dynamic analyses were used to better represent the expected buildings' responses.
The showroom is a steel/wood hybrid structure with steel moment frames and wood shear walls as the lateral system. The rear half of the building houses offices and a storage mezzanine for the facility's service department.
The four story parking structure serves as a showroom, service facility, and storage building for the dealerships inventory. The building is framed with pre-stressed concrete gravity members and pre-cast, tilt up concrete shear walls serve as the lateral force resisting system. A cast-in-place concrete topping slab acts as the structural diaphragm, tying the various elements of the building together. The service department of the facility is located on the second story of the parking structure, which contains 48 service stalls. Three levels of parking above the service department hold the delearship's inventory.
