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.
