TVA Allen Combined Cycle Plant
Location: Memphis, Tennessee
Client: Tennessee Valley Authority (TVA)
Geotechnology, Inc. was selected to provide the Tennessee Valley Authority with geotechnical services for a $160 million design/build project located south of Paul R. Lowry Road in Memphis, Tennessee. Subsequently, we provided a wide range of services in the development of the TVA Allen Combined Cycle Plant.
TVA Allen Combined Cycle Plant Project Background
This project consists of the construction of a greenfield power production facility. The primary structures include two combustion turbine-generators and a turbine hall building. They also include two heat recovery steam generators (HRSGs) and one steam turbine generator (STG). In addition, various other structures including tanks, pipe racks, cooling towers, a warehouse and an administrative building are being planned.
Geotechnology, Inc. provided geotechnical services including subsurface exploration and site-specific seismic study. We also oversaw SPT- & CPT-based liquefaction hazard evaluation, settlement analysis and CFA Deep foundation (Augercast & drilled-displacement piles) in both static and post-liquefaction conditions. Finally, we conducted Lateral Spreading Analysis.
