pneumatically placed, greatly reduces labor cost and time. Notable projects Conco's portfolio includes involvement on many renowned construction projects throughout the Western U.S. A prime example is on February 15, 2014, Conco broke the Guinness World Record for the largest continuous mat pour to date in just hours. The event was verified by an official Guinness World Records adjudicator who was on site during the pour. [4] The massive mat pour required a fleet of 227 trucks that made 10 to 14 concrete drops for a total of 2,100 trips. Conco used eighteen concrete boom pumps strategically located around the site to place 82 million pounds of concrete to complete an almost 20-foot-thick foundation. The mat pour was for the new Wilshire Grand Center that is being built by the Turner Construction Company in downtown Los Angeles and is slated to become the tallest building in the U.S. west of the Mississippi. [5] In the summer of 2013, Conco was retained by the general contractor, American Bridge/Fluor Enterprises, Inc. JV, to assist on the repair of 32 anchor rods on the eastern span of the new Bay Bridge in San Francisco, CA. A permanent fix was designed that involved a complex series of steel saddles and post-tensioned jacket walls that were used to provide the required clamping force to secure the bridge deck framing to the E2 crossbeam. The concrete jacket wall structures were placed in three pours totaling 380 cubic yards. Due to restricted access and rebar congestion, much of the concrete was pumped 250 feet and then injected into the forms through ports at strategic locations. [6] In 2012, Conco was awarded the concrete contract for the new $1.2 billion San Francisco 49ers Levi Stadium. The scope of the project called for extensive concrete work that consisted of slabs in excess of 2,000,000 square feet and used more than 65,000 cubic yards of concrete to complete. In order to meet the demands of the ambitious timeline for completion of the foundation, Conco worked in four separate areas simultaneously. The same approach was taken for the many deck pours that needed to be done. The Levi Stadium is another Turner Construction project and opened in the fall of 2014. [7] Another significant project was the parking structure for the Nokia Theater L.A. LIVE + project in Los Angeles, CA that opened in 2007. Anschutz Entertainment Group (AEG) was the
