Sunnyvale-based Level 10 Construction announced earlier this month that erection of its new downtown San Jose project, 200 Park Ave., may take significantly less time using a new hybrid core system.

200 Park Ave., pictured above in a rendering provided by Gensler, is the first new speculative office project in downtown San Jose in 10 years. The new 19-story office building will have 16 levels of Class A flexible workspace, with three levels of above-ground parking and four levels of below-ground parking.

Level 10 Vice President Casey Wend, who is overseeing 200 Park Avenue, says the project will be the first in California to use “SpeedCore,” a new hybrid core system.

As described by the American Institute of Steel Construction:

SpeedCore is a revolutionary concrete-filled composite steel plate shear wall (CF_CPSW) core. With this remarkable system, erection will take an estimated 40% less time to complete than it would with a traditional cast-in-place reinforced concrete core.

Erection of the hybrid core begins with pre-fabricated panels consisting of two structural steel plates held in place with cross-connecting tie rods. After erection, these panels are filled with concrete, creating a unique sandwich-style structure that provides strength and stability along with the benefits of rapid erection. Additionally, SpeedCore is a non-proprietary system, meaning many American steel fabricators can produce the panels.
