Rady Children’s Hospital in San Diego broke ground on a 500,000-square-foot intensive care unit (ICU) and emergency services pavilion as part of a master plan to expand its campus.

The seven-story, $1 billion project will house 140 ICU beds and four operating rooms, double the size of the emergency department from 46 rooms to 86, and expand treatment space for behavioral health services.

A café, kitchen, and rooftop helipad are also planned.

The project will include demolishing part of an existing 1950s structure to make way for the new pavilion.

Construction costs will be funded by a $200 million pledge from Ernest and Evelyn Rady.
