Forensic/Retrofit/Rehabilitation – STRUCTURE OF THE YEAR 2025 WINNER: Millennium Tower Perimeter Pile Upgrade

San Francisco’s Millennium Tower is a 58-story luxury condominium building developed between 2005 and 2009. Over the next ten years, the structure settled more than 18 inches and tilted a similar amount, resulting in litigation. To address these issues, SGH designed a unique structural upgrade, which involved installing 18 piles along the building’s north and west sides extending to bedrock to arrest further settlement and provide for gradual recovery of tilting. Completed in September 2023, the upgrade has proven effective. Mr. Hamburger will describe the structural and geotechnical analyses performed, and the retrofit details.
