Location: St. Louis, Missouri

TSi completed the geotechnical investigation and recommendations report for use in the design and construction of the new $20 million College of Business Administration Building at the University of Missouri-St. Louis campus. The project site is located north of the existing Express Scripts Hall (ESH) in an area where the topography slopes downward relatively steeply to the north and west. The proposed building will be a three-story structure, with the lower level exposed on the north side but below grade on the south side in consideration of the sloping ground surface. A below-grade tunnel and an at-grade walkway with canopy will connect the new structure to ESH. In plan view, the building shape will be an irregular steel frame structure with brick veneer, with dimensions of approximately 75 by 230 feet. Column loads of up to approximately 350 kips are anticipated. Based on the column loads and the moderately compressible soil encountered at the site, the building will be supported by drilled shafts socketed into the sandstone bedrock, the surface of which averages about 20 feet below the ground surface.
