After about 20 hours of continuous pouring, judges from Guinness World Records verified that the concrete pour at the $1 billion Wilshire Grand project in Los Angeles is the largest uninterrupted pour of slurry on record.
It took 208 trucks making as many as 10 deliveries each last weekend to complete the pour. In all, 21,000 cubic yards of concrete were poured to form the foundation for the 73-story tower.
The project, led by Turner Construction for developer Korean Air, includes office space, restaurants, retail, and 900 luxury hotel rooms. Scheduled to open in 2016, the tower will be the tallest building west of Chicago. AC Martin Partners is designing the 1,100-foot-tall tower, with Thornton Tomasetti as structural engineer.
Here are some of the pour’s impressive numbers:
• 19 pumps dispensed concrete into the pit through 13 hoses
• 24 temperature sensors provided hourly readings (the concrete should remain between 120 and 160 degrees)
• 45 degree water pumped through 100,000 feet of polyethylene hose snaked throughout the pit will help counteract the natural heating
• The concrete weighs some 82 million pounds

University of Toledo, Memorial Field House
27th Annual Reconstruction Awards—Silver Award. Memorial Field House, once the lovely Collegiate Gothic (ca. 1933) centerpiece (along with neighboring University Hall) of the University of Toledo campus, took its share of abuse after a new athletic arena made it redundant, in 1976. The ultimate insult occurred when the ROTC used it as a paintball venue.

27th Annual Reconstruction Awards—Silver Award. Administrators at the University of Connecticut Health Center in Farmington didn’t think much of the 1970s building they planned to turn into the school’s Cell and Genome Sciences Building. It’s not that the former toxicology research facility was in such terrible shape, but the 117,800-sf structure had almost no windows and its interior was dark and chopped up.
