The Conco Companies Sets Records with First Mat Pour of The Grand


The Grand is an immense, much anticipated mixed-use development project in the Los Angeles neighborhood of Bunker Hill that commenced construction in May 2019. To kick off the project, Los Angeles commercial concrete contractors, The Conco Companies delivered an impressive demonstration of its skills and expertise. For the first of the two towers to be erected for the project, Conco provided the second-largest continuous casting of a foundation in Los Angeles in a mere 15 hours. The project with the top honors in this category and the recipient of Guinness World Record recognition in 2014 was the Wilshire Grand Center, also completed by Conco.

The metrics for the foundation mat pour of this 39-story residential tower designed by Frank Gehry are staggering: 140 skilled Conco employees placed 13,275 cubic yards of concrete at an approximate rate of 1,000 cubic yards per hour. The 39,303 square foot concrete mat varies in thickness from 6 feet to 12 feet and weighs roughly 27,000 tons. Throughout the 15-hour mat pour, eight state-of-the-art concrete pumps worked to pump and place the concrete while 1,348 truck trips to six batch plants were completed.

In addition to the speed of its service delivery and the seamless coordination with multiple stakeholders such as developer Related Companies, the Los Angeles City Council, and the Department of Transportation, Conco also achieved the feat of zero injuries during this first phase of the project. Conco prides itself on prioritizing job site safety, and true to Conco’s focus, despite the dizzying speed of the mat pour, there were no injuries. The experience and expertise behind Conco’s reputation as the top supplier of commercial concrete services – no matter the scale or difficulty of the project – was certainly on full display during this massive mat pour.

The Conco Companies’ mission is to be the best supplier of concrete services in the Western U.S. and to bring expertise and incomparable quality to each project. We continue to upgrade and expand our facilities to better serve the growing market for commercial, educational, parking structures, public works projects, and other development.
