Almost a decade ago, Santa Clara Unified School District started its search for land to build a new school system. Over eight years later, the Agnews Campus is finally becoming a reality. This project consists of an Elementary School, a Middle School, a High School, and all associated sports fields, parking lots, and major utility connections.
Over the last year, 3500 Zanker Road in San Jose, CA, has transformed from a decrepit and abandoned mental hospital, to a 56-acre mud pit, into the early makings of the next great educational institution. The old existing structures, water tower, and roads are gone. The soil stabilization system, underground utilities, and building foundations have been installed.
The largest K-12 school construction project in the country is currently over a quarter of the way to completion and has recently hit some major milestones.
On September 20, the last underground column of the entire site’s soil stabilization system was completed. The project utilized the Cement Deep Soil Mixing (CDSM) system, which are underground concrete columns installed directly under each building’s foundational elements across all three campuses. The entire campus totaled just over 10,000 CDSM columns, using 8.7 million gallons of water and 672,000 tons of cement in 145 working days. In the end, over 75 miles of underground concrete columns were installed.
As the CDSM was wrapping up at each campus, the building projects were given the green light to begin digging foundations, pouring slabs, and preparing for structural steel.
On October 7, the first piece of steel at the Elementary School was set in place. Since then, three of the four Elementary School buildings have completed structural steel erection and are continuing with decking and interior build-out. In similar timing, two of the five Middle School buildings have completed structural steel erection as well.
