Pittsburgh, PA PPG Paints Arena Pittsburgh, PA a TERRATEST Company OWNER / GENERAL CONTRACTOR: Sports & Exhibition Authority of Pittsburgh, PA GENERAL CONTRACTOR: PJ Dick/Hunt Joint Venture - Pittsburgh, PA ARCHITECT: Populous - Kansas City, MO STRUCTURAL ENGINEER: Thornton Tomasetti Group - Kansas City, MO GEOTECHNICAL ENGINEER: Geo Mechanics, Inc - Elizabeth, PA PRODUCTS: Geopier GP3® System - Geopier Impact® System SOLUTION The differential settlement criteria for the ice floor was 0.25 inch, and 0.5 inch for the other arena areas. To provide uniform settlement control, drilled shafts were used for arena footings, and Geopier elements were used for the ice floor and arena slabs. Given the variability of the underlying soils and the differing settlement criteria between the arena and ice floor, Geopier® elements were installed using both the Geopier and Impact Pier® installation methods. GeoConstructors, Inc. installed over 700 Geopier and 400 Impact pier elements on this project. Geopier elements were utilized for support of the ice surface since fill depths ranged up to 18 ft and were above the water table. As the fills got deeper, alluvial sands, groundwater and caving soils were encountered, Impact pier elements were installed up to 40 ft deep. DESCRIPTION As a leading entertainment venue, this 735,000 sf, six-story arena is the regional epicenter for athletic events, concerts, and family shows in Western Pennsylvania.
