Clayco, Concrete Strategies Receive Three Quality Concrete Awards
St. Louis, MO (Jan 17, 2008)
Clayco Inc. and Concrete Strategies Inc. recently received three Quality Concrete Awards from the Concrete Council of St. Louis.
Recognized for their work on Casino Queen, the Central Underground Garage at Washington University in St. Louis, and the Edward A. Doisy Research Center core and shell at Saint Louis University, Clayco and Concrete Strategies were selected by a panel of prominent concrete experts.
The grand opening of the new Casino Queen ushered in a new era of tilt-up construction in St. Louis. The two-level, tilt-up concrete building with a steel roof features 22-foot-high ceilings, a 38,000-square-foot gaming floor, buffet restaurant, casual café, steakhouse, VIP lounge, coffee bar, deli and stage bar. Completed in August 2007, the 238,000-square-foot entertainment complex was built on land while the entire gaming floor was entirely rafted on a floating concrete barge. The construction of the gaming floor consisted of precision cut, 3-inch foam sheets that were stacked in an alternating, interlocking pattern all pinned together. Once the foam was pinned, a 12-inch thick concrete cap was poured as the base for an under-floor duct system. After the ductwork was installed, the concrete slab that would act as the gaming floor was poured. This floor was carefully anchored to the basin prior to filling the basin with water, which makes the Casino Queen the first land-based “boat in a moat” casino in Illinois.
Saint Louis University’s Edward A. Doisy Research Center is part of an $80.5 million project that provides new, state-of-the-art medical research facilities at the university’s Health Sciences Center. The $60 million medical research building at Grand Boulevard and Chouteau Avenue in midtown St. Louis includes a 10-story tower at the north end of the site, near Grand and Chouteau, with the first two floors extending toward the south and connecting in a covered walkway to the SLU School of Medicine. The structural concrete for the project involved construction of a concrete elevator core and shear tower that provide structural bracing for the entire building. The building also utilized radius and straight perimeter foundation walls to create a foundation capable of not only supporting the structure, but also creating a recognizable and distinct shape for the structure. Clayco completed the core and shell in November 2007.
The Central Underground Garage is a three-story cast-in-place concrete parking structure that serves as the foundation for Washington University’s new University Center, which currently is under construction. Completed in June 2007, the parking garage extends 35 feet below the grade elevation and accommodates 523 parking stalls. Each level is approximately 70,000 square feet. A 15-inch-thick concrete lid separates the garage from the University Center and also includes transfer beams as large as 4 feet by 8 feet. Three elevator shafts that will be part of the University Center were incorporated into the garage. The Central Underground Garage houses many of the main utilities and equipment required for the University Center.
“We are pleased to have received three awards from the Concrete Council of St. Louis,” said Barclay Gebel, vice president of operations at Concrete Strategies. “These awards confirm our commitment to developing award-winning projects that exemplify the art and science of building.”
