Summary
- 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.
- 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.
- That gap between excavating and injecting grout went against protocol and “could very well explain the comparatively rapid settlement and tilting that occurred during pile installation in August.”
- SFDBI said they would inspect between each additional pilot pile installation to ensure work was proceeding as expected.
- NBC News reported in 2016 via a public records request that the Millennium Tower was previously expected by its builders to settle a maximum of 5.5 inches by the year 2028.
