Construction on the Wilshire Grand project in downtown Los Angeles broke a world record on Sunday for the longest concrete pour.

Work began shortly before 5pm on Saturday as crews poured 21,200 cubic yards of concreate, weighing about 84mn pounds, from 208 trucks

The pour laid the foundation for a planned 73 story (1,100ft high) luxury hotel, office and retail space in downtown LA, which is being developed by Korean Air. When the $1bn project is complete in 2016 the building will be the tallest west of the Mississippi.

A representative from the Guinness Book of World Records was on hand to confirm the record.

The record-breaking pour involved 300 workers and took about 20 hours.

According to a report in the Los Angeles Times, eight concrete plants and a backup were used – each no more than 20 miles from downtown to ensure the trucks could deliver the concrete within 90 minutes of being mixed. Any longer and the concrete would not be usable. Once on site, 19 pumps pulled the concrete from the trucks into more than a dozen hoses used to funnel it into the pit.

The incredible feat surpassed a record set by crews pouring the foundation for Las Vegas' Venetian hotel back in 1999.
