Thornton Tomasetti is providing structural design services for Phase I of this iconic regional transportation hub; a gateway to Orange County, providing multimodal transit services for rail, bus and roadway. The program includes a 66,500-square-foot terminal building with a grand hall, ticketing and retail spaces beneath a soaring open structure composed of ETFE cushions. The project includes the Intermodal Terminal, the Metrolink/Amtrak concourse bridge, and the Stadium Pavilion bridge. The building program for the Intermodal Terminal features a grid shell vault structure and a three-story interior terminal building that are structurally connected. Future phases of the development call for residential units, offices and further retail functions.
The transit center will be designed to achieve LEED Platinum certification by incorporating initiatives including energy and potable water consumption reduction, storm water runoff, construction, operational waste, and air emissions reduction, optimization of climate conditions, and open space areas.
