The Conco Companies are doing the structural concrete work for the new Wilshire Grand Hotel in Downtown Los Angeles. As part of the project, Conco broke the Guinness World Record by completing the largest, continuous mat pour at the site. The pour took 21,200 cubic yards, or 82 million pounds, of concrete and was done in just 18 ½ hours. We are also doing a poured-in-place core wall that goes up the building surrounded by slab on metal deck. The core is 130 ft. X 35 ft. with some walls up to 4 ft. thick. In addition, Conco purchased and is using a new state-of-the art electric pump to pump concrete 400 ft. horizontally and then 1,000 ft. vertically to reach the upper levels of the Wilshire tower.

The Conco Companies are providing concrete services for the new U.S. Federal Courthouse under construction in Downtown Los Angeles. Known as the “Cube” for its unique shape, the $400 million project will be one of the safest buildings in terms of bomb threats or earthquakes with an innovative design that permits the cubic volume to “float” over a stone base. The project broke ground in August 2013 and is scheduled to be finished in 2016. Located on a 3.6-acre site, the 10-story courthouse will include 24 courtrooms and 32 chambers for judges as well as housing district judges, jury assembly facilities, and offices for the U.S. Marshals. The 630,000 GSF building will also have one level of below-grade parking.
To address the issue of the courthouse’s California location, seismic design was a part of the structural engineering process. SOM designed and engineered a state-of-the-art roof truss system to control lateral drifts. The project has already earned a Green Good Design award for Green Architecture in 2014.
