200 Park, a 19-story office building that will be the tallest office tower in San Jose, Calif., when it is completed, has begun erection. It is the first building in California to be built using the SpeedCore system and only the second SpeedCore project in the United States. The first is Rainier Square Tower in Seattle, and both were designed by structural engineer Magnusson Klemencic Associates, which developed the system.
Around the time construction started in March, the project’s general contractor, Level 10 Construction, released a video depicting the conceptual structural steel sequence of the tower. It shows how 200 Park’s SpeedCore system employs fabricated steel wall panels, fabricated by AISC member Schuff Steel, that are supported by stanchions and filled with high-strength concrete. Each prefabricated steel wall panel carries up to eight floors of steel framing, allowing construction to continue independent of concrete curing times.
The project’s use of SpeedCore is expected to reduce construction time by three months, resulting in an estimated completion date of May 2023. SpeedCore also helped the Rainier Square Tower finish its core nine months ahead of schedule.
When it is finished, 200 Park, owned by Jay Paul Company and designed by Gensler, will comprise 937,000 sq. ft, including 26,000 sq. ft of outdoor terraces. Find out more about the project and its use of SpeedCore in Building Design + Construction’s article.
