High-Rise in San Francisco Continues to Sink
In San Francisco, repairs to fix a luxury high-rise foundation from sinking further into the earth, and to stop the structure from tilting, was recently put on hold.
The $100 million project was halted after it was determined that the building had sunk another inch during the repairs.
A spokesperson for the tower said that the project has been placed on hold while structural engineers try to understand why there has been an “increased settlement rate” and are looking for “available means of mitigating this.”
The 58-story structure opened in 2009 and by 2016 the building had sunken a total of 16 inches. The settling foundation also created a 2-inch tilt in the structure.
While the building has been deemed “safe,” a resolution was reached last year with homeowners to repair the structure by installing concrete and anchors to the building in order to provide foundation support … which has now been halted due to additional sinking.
Vulnerable high-rise structures like this can also be found in Los Angeles, and according to data from the U.S. Geological Survey, a simulation of a 7.8 earthquake along the San Andreas fault collapsed as many as five high-rise buildings in the L.A. area.
While San Francisco has started to retrofit buildings like this, hopefully cities like Los Angeles will likewise start inspecting high-risk steel-framed buildings in their areas.
