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. As geotechnical engineer of record, Rutherford + Chekene developed geotechnical parameters for use in soil-structure interaction analysis to minimize seismic loads transmitted to the superstructure.
