There was no measurable settlement during the Dec. 1-3 drilling for the second permanent pilot pile installed at the northwest corner of the troubled Millennium Tower in San Francisco, says Ronald O. Hamburger, engineer-of-record for the perimeter pile upgrade designed to stem settlement of the 645-ft-tall residential condominium.
Shimmick Construction successfully completed the 36-in.-dia pilot pile casing installation at San Francisco’s Millennium Tower, proving the efficacy of the initial step of a less-disruptive construction method designed to allow the paused foundation fix to resume.
San Francisco Dept. of Building Inspection advises the Millennium Tower homeowners association to “refrain from resuming” the pile foundation retrofit for the settling 645-ft-tall condominium until a new approach to the fix is reviewed by the city.
