Since its founding in 1959, Berkel has grown to become one of the largest piling contractors in the U.S. Our work consists of specialized foundation and construction services such as installing Auger Pressure Grouted (APG) piles and Auger Pressure Grouted Displacement (APGD) piles, Shoring and Earth Retention and Ground Improvement and Stabilization.
- ExcavationHartsfield-Jackson Atlanta International Airport underwent a $1.2 billion dollar expansion project centered on the construction of the new Maynard H. Jackson International Terminal. Passenger access between the new International Terminal and the domestic airport facilities is primarily via underground Automated People Mover (APM) trains. The new International Terminal is located approximately 1/2-mile from the terminus of the existing APM tunnel. A cut-and-cover method was selected for the construction of the APM tunnel extension to allow the construction team to best address unknowns and potential obstructions. The construction of the APM extension required an excavation support system for a 450-ft long, 55-ft deep excavation across Taxiway Dixie and a 900-ft long, 35-ft deep excavation beneath the basement of existing Concourse E. The excavation under Concourse E required both excavation support and support of the existing columns over the proposed excavation zone.
