The pilings were drilled today. There are 28 continuous flight auger piles. The piles are 16 inches in diameter and 30 to 35 feet deep. It is amazing to see how they install these! They drill a hole to the pile depth with a hollow auger, then pump concrete under pressure through the drill. As the auger is removed concrete is pumped to the top of the hole. Then a steel reinforcing cage is lowered into the wet concrete.
