Apple selected SANDIS as the off-site traffic engineer responsible for 176 acres of the new Apple Campus. Planning to house over 13,000 employees, SANDIS worked diligently to analyze and address ingress/egress and the possible traffic impacts of the new campus.

sandis sought Caltrans approval quickly and efficiently--successfully cutting a two-year process in half.

In this unique Bay Area transportation public/private partnership, half of the improvements fell under Caltrans direction, while private funding financed the remaining half. Through efficient work and a time-oriented team, SANDIS received Caltrans’ approval within a year, successfully cutting a two-year process in half. Due to SANDIS’ strong communication skills, the SANDIS team was able to remain in coordination with all involved parties and complete the proposed services in a very timely manner.

Welch Road Corridor

Stanford University

To support the increase in hospital square footage, Sandis designed all new backbone utilities along the roughly 3,300 linear foot Welch Road corridor

Stanford Medical Center is a healthcare campus that provides world renowned facilities for patient care and cutting-edge research. To sustain and expand these facilities, the medical center determined two new hospital buildings were required. One building would be an expansion of the existing Lucile Packard Children’s Hospital, while the other would replace the aging main hospital building. Sandis was retained to design the necessary roadway and infrastructure upgrades to service these two new facilities.
