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.
