Building workers in Los Angeles have broken the world record for the largest continuous concrete pour.
They poured 82 million pounds (37.2 million kg) of concrete during an 18-hour period, as they laid the foundation for a 1,100 feet (335 metre) skyscraper.
Guinness World Records adjudicator Michael Empric said the round-the-clock pouring for the skyscraper - to be known as the New Wilshire Grand - involved 208 trucks making more than 2,100 trips.
Ultimately, 21,200 cubic yards (19,385 metres) of concrete were poured, beating the record of 21,000 cubic yards (19,202 metres) set by The Venetian hotel in Las Vegas in 1999.
Empric - who had just finished judging a successful Valentine's Day effort to set the record for the most people feeding each other simultaneously - said he learnt a lot about concrete and the challenges of such a pour.
