Construction of the new 73-storey, 335m tall new Wilshire Grand mixed-use building for owner/developer Korean Air in Los Angeles, USA, started in February 2014 and has already claimed the world’s largest continuous concrete pour.
The 16,200m³ pour, for the foundations some 24-29m below street level, gained a place in the Guinness World Records and beat the existing record set by The Venetian hotel in Las Vegas, Nevada, USA, in 1999, says Guinness World Records’ Michael Empric.
The project’s general contractor, Turner Construction Company, worked with The Conco Construction Companies, one of the largest pumping and belt companies in the US, to coordinate the fleet of pumps, including 16
When completed in 2017, the project will comprise a four-star hotel; worldclass restaurants; retail space, and 37,200m² of new office space.
During the pour 12 Putzmeister truck-mounted concrete boom pumps ranging from 32-47m, two Putzmeister placing boom towers, and two Putzmeister trailer-mounted concrete pumps were strategically placed both inside and above the excavation.
A total of 19 pumps were utilised for the pour, which included 227 ready mix trucks making more than 2,100 trips and pouring almost 39 million tons (35.4 million tonnes) of concrete during an 18.5-hour period.
