Terra-Petra boots-on-the-ground for World Record Concrete Pour DTLA Wilshire Grand

17Feb2014

Terra-Petra had "boots on the ground" during the record breaking concrete pour for the new Wilshire Grand Hotel in Downtown Los Angeles – February 16, 2014. We were charged with the responsibility of performing the below grade waterproofing system inspections during this world record pour. We would like to thank Korean Air, General Contractor – Turner Construction, and the design team led by AC Martin for allowing us to be part of this historic occasion.
