After comparing systems, general contractor Kunzik & Sara knew prefabricated concrete was the right building system for the rooftop parking required for the new El Cajon Mercedes Dealership.
Given precast’s ability to span farther distances than other building systems, Gary Whitfield & Associates started designing for Clark Pacific’s 72 foot long double tees that easily support the roof parking loading. With the additional span, there are fewer columns, allowing for more capacity and a larger turn radius for the service bays. Hollowcore planks were used for the speed ramps which gives the dealer additional storage under each ramp.
In addition, a precast structure can be delivered in 30-40% less time than traditional construction methods, helping the dealer open their doors sooner.
