The concrete for the seating areas and suites at the new Sacramento arena is being poured now... in Woodland.
Inside Clark Pacific's Woodland plant, there's the "plop plop" of about a dozen people in orange safety vests and hard hats pouring and the "whoosh whoosh" of them smoothing out concrete in metal forms that are between 30 and 38 feet long. In eight hours, the forms will have cured and will be hauled away by a large crane to a storage facility.
The company's president, Bob Clark says the forms weigh as much as 23,000 pounds.
"There's a whole system of how they do it and how they flow. You hear that noise? That's a vibrator trying to get some of the air bubbles out and consolidate the concrete. So, once they're all done being poured, they continue doing all the finishing to make uniform, flat surfaces."
Tom Anderson is the Senior Project Manager for Clark Pacific. He says the company is manufacturing about five of these arena sections of differing heights every day.
"On the upper bowl, it's all consistent. It's all the 22-inch. And likewise at the Suite tub, it's all a uniform height. On the lower bowl, the arena changes. The height changes every several steps. You go up, kind of is parabolic. So, it goes for a nine-inch rise all the way up to a 12-inch rise."
Clark Pacific says it will produce about 700 forms including the concrete steps that will fit in between the longer forms being poured now.
Sacramento Metro Chamber President Peter Tateishi toured the facility with the company's president. Tateishi says the arena has generated $200 million in business for companies in the Sacramento region.
"The bulk of the work hasn't been done. We were doing demolition, excavation and now concrete pour. But, you know just even talking here today, we're learning that he's able to put 50 people on this job site for the next 10 months. That's a huge opportunity."
The Sacramento Kings say 80 percent of the contracts signed so far have been with companies in the Sacramento region.
The sand and gravel for the concrete is sourced from the Cache Creek area of Yolo County.
Clark Pacific says it will begin installation of the forms by mid-May and complete the job in August.
The company also made the concrete pre-casts for Levi Stadium in Santa Clara.
