Mortenson and Clark Construction have reached substantial completion on the $1.4 billion Chase Center in San Francisco after starting construction 30 months ago. The entertainment and sports complex will be home to the NBA's Golden State Warriors and is expected to host 200 other events each year.
The 18,000-seat arena is the centerpiece of the new 11-acre development, which features two new 11-story office buildings that will serve as ride-sharing giant Uber's new headquarters. The project also includes more than 3 acres of public plazas and open space as well as retail space that can accommodate more than 20 stores.
Mortenson-Clark, at peak construction activity, had up to 1,500 workers on site and placed as much as $2.8 million of work a day. The JV also used 4D modeling and an "innovative" construction strategy that saw the "unraveling" of the arena from the project's other structures and a quadrant approach used to build the arena instead of a more traditional one. Each quadrant and each quadrant level had schedules, which allowed crews to make sure that the project not only advanced as quickly as possible but that all levels of each quadrant were completed at the same time.
The Warriors have also proposed building a hotel and condos next to the new center, but the team has released few details so far. What has been reported is that the hotel will feature 142 rooms and would be operated by SH Hotels and Resorts, an affiliate of Starwood Capital Group. The 24 condos would be market rate. Construction on these components could start as soon as 2021 and open in 2023. The hotel and residential building would replace an approved and planned 24,000-square-foot retail building.
If the Warriors move forward with the new plan, it would require approval from the San Francisco Office of Community Investment and Infrastructure and other city agencies.
If it comes to it, the Warriors might be up for another zoning fight because they were victorious against activists that tried to stop construction of the Chase Center. Local groups argued that the center's construction and eventual operations would be disruptive to patients at the nearby women's and children's hospitals. The lawsuit went all the way to the California Supreme Court, which decided in favor of the Warriors. The legal battle forced the team to delay by one year its inaugural season at the Chase Center.
