The engineer responsible for the troubled fix of the Millennium Tower acknowledged that the building is continuing to tilt about 3 inches a year since work began.
The tower is now tilting some 26 inches north and west at the corner of Fremont and Mission streets.Monitoring data shows that 10 inches of that tilt and about 2 inches of settlement occurred during work on the fix last year.
At the current rate, the tower’s lean could reach the functional 40-inch maximum – the point Hamburger says the elevators and plumbing may not continue to operate – in just a few years without the fix. Installing 18 steel piles to bedrock now is the best way to stop the tilting and possibly reverse some of it, City Supervisor Aaron Peskin told supervisors.
