Construction-phase consultation was provided on an as-needed basis for the Nationals Stadium. Qamar Kazmi served as Project Manager for the geotechnical investigation and design for a new 41,000-seat baseball stadium along the Anacostia River waterfront, in southeast Washington, D.C. Prestressed, precast concrete piles were used for the support of the main concrete and steel frame structure. Static and dynamic testing of piles was performed. A perimeter and under-slab drainage system, as well as a drainage system below the ball field, was used to control groundwater.
