Perimeter Pile Upgrade”


Shimmick Construction for “301 Mission


Te Millennium Tower Foundation Stabilization project represents one of the most technically complex and high-profile foundation interventions ever executed on a high-rise residential structure. Located in downtown San Francisco, the 645-foot-tall tower had become


a national headline due to its significant settlement and lean — including approximately 18 inches of vertical sinking and 24 inches of tilt. Tis high- stakes project sought to stabilize the building, halt further movement, and regain public confidence in one of the city’s most prominent skyscrapers. Shimmick Construction retrofitted the foundation by installing 18 deep


foundation piles drilled to bedrock – some 300 feet below grade. Te complex operation took place on a severely limited footprint surrounded by active traffic. Despite initial skepticism and significant public scrutiny, Shimmick successfully completed the project on schedule and within budget. Also selected as a finalist in this category were Myers-Shea JV for “Yreka Complete Streets Rehabilitation” and Teichert Construction for “State Route 99 Merced CRCP Rehabilitation.”


Shimmick Construction received a Constructor award for 301 Mission Perimeter Pile Upgrade.
