Citigroup Processing Center

2007 TCA Tilt-Up Achievement Award - Office Division

Article tools: Coming soon!

Although Citigroup originally sought a brick façade for their 175,000-square-foot office building in Urbandale, Iowa, the tight construction schedule (they wanted to move into the office in just under six months) made masonry impossible. As such, Clayco, who had previously completed a brick-inlay Tilt-Up structure for Citigroup’s regional headquarters and processing center in O’Fallon, Mo., proposed a similar structure for the Urbandale site.

While a traditional brick design would have taken significantly longer, the Tilt-Up work on this structure was completed in just 30 days.

Clayco used 35,000 square feet of brick inlay with a sandwich panel insulation system to give the processing center an exterior that imparts a corporate feel and coordinates with the other structures in the surrounding office park.

Large structural panels placed at the front of the building support a great amount of spandrel glass.

About the TCA

Founded in 1986, the Tilt-Up Concrete Association (TCA) strives to improve the quality and acceptance of site-cast Tilt-Up construction, a method in which concrete wall panels are cast on-site and tilted into place. Tilt-Up construction is one of the fastest growing industries in the United States, combining the advantages of reasonable cost with low maintenance, durability, speed of construction and minimal capital investment. At least 10,000 buildings, enclosing more than 650 million square feet, are constructed each year using this construction method.
