The Conco Companies is providing a full range of concrete services on the 221 N. Mathilda Project for the San Francisco based owner/developer Spear Street Capital.   The three-story, Class A office building also has a partial below grade parking structure with parking stalls. The project is on a 4.3 acre greenfield site located between N. Market Ave and Sobrante Way just off W. California Ave and close to the Sunnyvale Caltrain station, the San Francisco Peninsula commuter rail service.   The building’s architect, SmithGroupJJR says the most significant design feature is the “striking, custom 2,000 sq. ft., laminated glass artwork that will span the building’s east façade.” 

Conco’s responsibilities on the project include providing concrete pumping, reinforcement, formwork, finishing, and shotcrete services.  During the project, we expect to place 7,600 cubic yards of concrete as well as shotcrete.  This project consists of 1,150,000 pounds of rebar and post tension reinforcement of which Conco is having placed by others due to factors beyond our control.  We started the project in August 2017 will complete the job in July 2018.
