The engineer trying to stabilize the Millennium Tower, a luxury residential skyscraper in San Francisco that is sinking into the ground and now leaning over two feet off of center, said the building is now tilting three inches per year.

Structural engineer Ronald O. Hamburger made the comments Thursday at a city hearing in which he pitched an updated fix for the building's foundation, NBC Bay Area reported.

The 58-story, 645-foot tall tower — opened to residents in 2009 — is now tilting 26 inches north and west at Fremont and Mission Streets in the heart of San Francisco’s financial district, according to NBC Bay Area.

Residents were informed that the building is settling unevenly and more than anticipated in 2016. The tower sits beside the Salesforce Transit Center, a bus terminal and potential future rail terminus for California’s high speed rail network currently under construction.

But efforts to stabilize the sinking and leaning skyscraper seemed to worsen matters. Engineers halted construction on the fix in summer 2021 so they could “determine why increased foundation movement was occurring and how this could be mitigated.”
