Record-Setting Concrete Pour in Los Angeles

Record-Setting Concrete Pour in Los Angeles

Portland Cement Association (PCA)

Over the weekend of February 15-16, Catalina Pacific Concrete/CalPortland successfully produced and delivered the concrete for the largest continuous concrete foundation pour in history. Ultimately 21,200 cubic yards of concrete were placed for the new Wilshire Grand, beating the existing record of 21,000 cubic yards set by The Venetian Hotel in Las Vegas in 1999. The Wilshire Grand is planned to be the tallest structure west of the Mississippi River.  When completed, this more than $1 billion world-class mixed use office and hotel project will ascend 73 stories skyward topping out at 1,100 feet.

The concrete placement began at 4:47 p.m. on Saturday, February 15, and was supplied from eight area concrete batch plants operating at full capacity throughout the night and into the morning. A fleet of 208 concrete mixer trucks delivered loads of concrete continuously until reaching the final record 21,200 cubic yards.

A project of such magnitude required precise logistics for raw materials replenishing all of the operating concrete batch plants through the concrete production facilities until the concrete was delivered to the project for placement. Included was around-the-clock transport and delivery of more than 200 truckloads of cement from CalPortland’s Mojave and Colton cement plants, approximately 65 loads of fly ash, and 1,340 truckloads of rock and sand to all operating concrete batch plants going on behind the scenes to support the epic event.
