Conco is responsible for the extensive concrete work. The project consists of slabs in excess of 2,000,000 square feet and will use more than 65,000 cubic yards of concrete.
For more details on the project see our blog posts: Awarded 49ers Stadium and The New San Francisco 49ers Levi’s Stadium.
Conco was awarded a concrete contract by Holland Partners for a 21-story luxury apartment building at 1650 Wewatta, which is next to the historic Union Station in downtown Denver. The project will include 288 apartment units, 260 parking spaces, and approximately 7,000 SF of retail space. We broke ground in early 2013 and should be completed in 2014. This project will be about 18,700 CY when complete.

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 all of the concrete and reinforcement services for the $20.5 million De La Salle H.S. STREAM Innovation Center. The 27,288 square foot, 2-story building will incorporate both “green” design and construction. The multi-disciplinary building broke ground in June, 2014 and is scheduled to open August, 2015. The Center will expand teaching and learning opportunities by allowing the school to increase course offerings to prepare students for a rapidly changing global job market. STREAM stands for Science, Technology, Robotics, Engineering, Arts and Mathematics.
This project had to be completed in a way that did not interfere with the busy school schedule and extracurricular activities associated with a highly reputable high school. Therefore, a large mat foundation pour was completed on Saturday and elevated concrete slabs were scheduled around important events.

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.
