Millennium Tower
SAN FRANCISCO, CA
|
|
At 645 feet in height, Millennium Tower is the tallest structural concrete building in San Francisco. The 1.2 million-square-foot, luxury high-rise residential complex consists of two towers—60-stories and 11-stories—and includes a Club Level with 20,000 square feet of high-end amenities, and 5 levels of subterranean parking. Webcor brought significant value to the project by eliminating the subterranean parking area under the high-rise tower and then sequencing the excavation into two phases. This enabled the high-rise tower erection—the longest item in the schedule—to begin earlier, saving the owner 8 months on the schedule and $6 million in construction costs. The building’s size and location required a massive foundation system with 10-foot-thick pile caps and a 3-foot-thick core wall. The site also required a highly unique, internal cross bracing system to eliminate off-site movements and support an existing building on the south side. Project awards include: American Concrete Institute Awards - Northern California Chapter, Construction Category Winner; American Society of Civil Engineers - Region 9, Structural Engineering Project of the Year; California Construction, Outstanding Project Management Award and Multi-family/Residential Award of Merit. |
