Stanford and Packard Children's Hospitals
Palo Alto and Stanford, California

The 1,000,000 sf new Stanford Hospital includes an emergency department, surgery suites, patient rooms, imaging areas, clinics, laboratories, offices and a cafeteria. The facility consists of four interconnected buildings in a quad formation around a central courtyard. The design incorporated a base isolation system on auger cast piles. Geotechnical challenges included mitigating impacts of potential liquefiable soil pockets in a way that allowed for a more economical design.

The 521,000 sf Lucile Packard Children's Hospital expansion contains all new facilities, including a hospital and a two-story parking garage below grade. Geotechnical challenges included rerouting utility lines prior to construction, mitigating potential impacts of liquefiable soil pockets and stabilizing the existing building foundation to allow for the adjacent deep excavation. Rutherford & Chekene developed geotechnical parameters for use in soil-structure interaction analysis to minimize seismic loads transmitted to the superstructure. R&C provided geotechnical engineering services for both hospitals.
