SLU Walk Receives Coveted Excellence in Achievement Award
St. Louis, MO (Feb. 27, 2008)
Clayco Inc. has received two Tilt-Up Achievement Awards from the Tilt-Up Concrete Association, including one of only two Excellence in Achievement awards granted in 2008. Concrete Strategies Inc., a Clayco partner, performed the tilt-up construction for both projects.
TCA’s highest honor was granted for Clayco and Concrete Strategies’ innovative work on the Saint Louis University Walk in midtown St. Louis. The firms’ other winning project is the new Casino Queen in East St. Louis, Ill.
According to TCA, Excellence in Achievement recognition is only granted for projects that exemplify the current state-of-the-art achievement in tilt-up construction with unique and inventive use of the tilt-up method. As its name implies, the SLU Walk is a walkway connecting SLU’s new Edward A. Doisy Research Center to other health sciences facilities. The project started as cast-in-place, but the team recommended a switch to tilt-up because it was more cost-effective, safer, cut the schedule in half and provided better quality. However, nothing like this had ever been done with tilt-up.
Barclay Gebel, vice president of operations for Concrete Strategies, explained, “Because of the shape of the panels – they are not level at the bottom – we had to pick up the panels flat from the casting bed and then rotate them plumb in the air using special rigging. It took approximately 10 hours to prepare each panel. There are cast brick slots in the back side of the panel, and we had to use a lintel beam to support the load of the brick. In addition to the challenge of placing each panel, the walkway goes uphill. To overcome this challenge, we poured all of the panels sistered together and then erected them vertically as they were cast on the casting bed.”
This revolutionary project was recognized in the special projects category. Clayco received a second Tilt-Up Achievement Award in the commercial division category for the new Casino Queen, the very first floating gaming facility with a land-based casino shell and a gaming floor. Built by Clayco/Legacy LLC Joint Venture, the 238,000- square-foot entertainment complex was constructed with TCA-grade A patch, the highest grade of patch, to enhance the facility’s structural integrity. Concrete Strategies overcame a limited site-casting area by using floor slabs twice and bringing in a 300-ton crawler crane to pick up panels that weighed approximately 200,000 pounds. With two levels, the structure also features a 38,000-square-foot gaming floor, which is rafted on a floating concrete barge. The Casino Queen is recognized as the first tilt-up casino construction in the St. Louis area.
“We are honored to have received two TCA Achievement Awards and the exclusive Excellence in Achievement award,” said Bob Clark, chairman and chief executive officer of Clayco. “The SLU Walk in particular is a history-making project, and it is always our goal to look beyond what has already been done and introduce new innovations in construction.”
