Jefferson Rotunda – UVA – Charlottesville VA

Facade retention and underpinning of existing facility for structure rehabilitation

The Jefferson Rotunda is one of two structures in the U.S. designated as UNESCO World Heritage Sites. Berkel designed/built an excavation support system to allow construction of interior and exterior below-grade basements and temporary support for excavation and renovation in the East Oval Room, East Courtyard, East Elevator, Southeast Terrace Office and Northeast Terrace Office. Berkel also designed/built the pictured steel shoring tower system to temporarily transfer roof loads of the porticos to foundations below while allowing unobstructed access removal and new capital replacement. The capitals were carved from 9,000-lb (40-kN) blocks primarily by computer-controlled lathe and finished by hand into 6,300-lb (28-kN) capitals.

New Stadium Project – Atlanta GA

A new Stadium, Plaza, and Bridge Extension for the city of Atlanta, the stadium will be home to the Atlanta Falcons. Berkel installed over 2100 x 18-in diameter Auger Pressure Grouted (APG) piles installed from depths of about 30-ft to over 110-ft for compression loads of 150 to 220 tons, tension loads up to 60 tons, and lateral loads up to 8.5 tons.

The Plaza and new Martin Luther King Jr. bridge structures included 24-in diameter APG piles to about the same depths and tested to 1000 tons compression load.

Additionally Berkel installed earth retaining structures for temporary and permanent project grading.

Wall Length: about 1000 Linear Feet
Supported Height: 26 Feet (Maximum)
3 System Types:

- Permanent Shoring/Temporary Wood Lagging (Future Cast-In-Place Concrete Facing)
- Permanent Shoring/Permanent Shotcrete Facing (Above Grade Cistern Location)
- Temporary Shoring/Temporary Wood Lagging

Wacker Chemical Plant - Charleston, Tennessee

A new polycrystalline silicon  production facility located on a 550 acre greenfield site. Design build utilizing 5,000 - 20" diameter Auger Pressure Grouted (APG) Piles up to 70' deep seated into rock. To achieve high uplift capacities in areas of shallow rock, 4.5 in. diameter rock sockets were drilled into the rock below the pile tip elevations and high strength rebar installed. To meet the fast pace schedule 5 Crane Mounted APG Drill Rigs and 4 Rock Drill Rigs were utilized. Design build methods resulted in owner savings and an expendited schedule.

APM Tunnel Extension – ATL Int’l Airport

APM Tunnel Extension for the Maynard H. Jackson Terminal at Hartsfield-Jackson Atlanta International Airport

Hartsfield-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 ½-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.
