Lucile Packard Children’s Hospital

Foundation Solutions with Soldier Piles and CFA Piles

The Stanford University Medical Center Renewal Project included expanding Lucile Packard Children’s Hospital, for which Malcolm was contracted by Preston/Top Grade to construct temporary shoring and drilled shaft foundations for the Make-Ready Utility Tunnel. Additionally, Malcolm was contracted by DPR to install the shoring and pile foundation system for the Hospital Expansion.

Approximately 2,400 linear feet of shoring were installed around the perimeter of the site. The shoring consisted of soldier piles, shotcrete lagging, and tie-backs. About 30% of the shoring was under OSHPD jurisdiction. The building foundation system consisted of 2,275 CFA piles, 24 inches in diameter, with an average depth of 65 feet. Fourteen test piles were installed and subjected to a combination of static load testing up to 1,200 kips, High Strain Dynamic Testing (HSDT), and Low Strain Testing (PIT).
