LOS ANGELES -- A Guinness World Records adjudicator says a Los Angeles project laying the foundation for the tallest building west of the Mississippi has broken the world record for the longest continuous concrete pour after 18 hours.
Adjudicator Michael Empric says 21,200 cubic yards of concrete were poured by 11:30 a.m. Sunday, beating the existing record of 21,000 cubic yards set by The Venetian hotel in Las Vegas in 1999.
The record completion was marked by blaring horns. Empric monitored the pour overnight by smartphone before meeting with contractors and engineers Sunday.
Sean Rossall, spokesman for the New Wilshire Grand, says 208 trucks made more than 2,100 trips and poured 82 million pounds of concrete.
The hotel is scheduled to be completed in 2016 and to open in 2017.
