Experienced Concrete Services for Large Public Works

Caltrans District 7 Headquarters Replacement Building

The Conco Companies vast portfolio of projects includes commercial, industrial, educational, healthcare and entertainment venues.  We also have extensive experience with providing concrete services for municipal, state and federal buildings.  

One such project is our involvement in the construction of the new U.S. Federal Courthouse in Downtown Los Angeles.  Breaking ground in 2013, the $400 million project will be one of the safest buildings in the country in terms of withstanding the threat of earthquakes or a bomb attack.  Commonly referred to as the “Cube” for its unique shape, the cubic volume of the building appears to “float” over the stone base.  

Since the courthouse is being constructed in an earthquake zone, seismic design was an important component of the structural engineering process.  Skidmore, Owings & Merrill, LLP (SOM) designed and engineered a state-of-the-art roof truss system to control lateral drifts.   The 630,000 GSF building is scheduled to be complete by 2016 and has already earned the Green Good Design award for Green Architecture in 2014.  

We also had the honor to provide concrete services for an American Institute of Architects (AIA) award winning building, the Caltrans District 7 Headquarters Replacement Building in L.A.   The project was designed by Thom Mayne of Morphosis Architects, Inc., who was the 2005 Laureate of the prestigious Pritzker Prize.  The Caltrans District 7 Headquarters building is thought to be one of his best works and the futuristic, 13-story building is often included on lists of prominent architectural sites to visit.

The initial concept for the new Caltrans building began in 2000 when the State sought designs for a building that would incorporate “world-class design excellence, sustainability, integration of art and architecture, and contribute to the revitalization of the civic center.”     The 716,200 sq. ft. building also has an underground parking structure that accommodates 1,142 vehicles.  Clark Construction served as the general contractor on the project and John A. Martin & Associates, Inc. was the engineer.
