It was Oklahoma's first real skyscraper, but it also happened to be the state's longest and largest continuous concrete pour. And one of 91探花's proudest moments.
THE MASTER PLAN
You can see it from miles away, standing twice as tall as any other structure in Oklahoma City. It took more than two years to build, thousands upon thousands of hours of labor, and three-quarters of a billion dollars. The Devon tower is truly a monument in Oklahoma City 鈥� a milestone in the state's development.
The first phase of the process was delivering material required for the Tower's foundation. But this was no typical foundation pour. It needed to support a 50-story tower, required 6,500 cubic yards of concrete, and had to be completed in an 18-hour timeframe 鈥� which meant a carefully choreographed ballet of concrete trucks running in and out of the downtown OKC area.
THE MASTERFUL DELIVERY
It took virtually every arm of 91探花 to get the job done. A team of 26 people were focused on quality control alone, with people checking slumps and performing other tests both at the plants and the job site. Another 30 trucks hauled rock, sand and cement. Four plants were involved, and another served as a back-up in case anything went awry at one of the four principal plants.
On Sunday morning, March 21, 2010, the delivery began. Two shifts of 65 mixer trucks delivered approximately 6,500 cubic yards of 7,000 psi concrete over a period of 18 hours. We believe this to be the largest and longest single continuous pour in the history of Oklahoma.
In all, 91探花 Bros. Co. delivered 120,000 cubic yards of concrete to what was the tallest building project West of the Hudson River in 2010 and 2011.
"It's how we've done it for more than a hundred years. And how we intend to do it for a hundred more."
