Abstract: A method is provided for using low-overhead equipment to perform a dynamic load test on pipe piles of a deep pile foundation for an existing building. The existing building is lifted to a predetermined elevation above grade and cribbing stacks are positioned to support the existing building at the predetermined elevation above grade. The cribbing stacks are spaced from each other enabling low-overhead equipment to maneuver underneath the elevated building to drill drive pipe piles and to position a drop weight used for dynamic load testing the driven pipe piles. Grout is pumped under pressure into the pipe piles continuously during the drill driving of the pipe piles so that grout exits through a grout port to mix with disturbed soil about the pipe pile to encase the pipe pile in a grout-soil mixture. Sensors are attached to the pipe pile being tested. The sensors provide information regarding the pipe pile impacted by the drop weight.

Abstract: Pile cap connectors are attached to pipe piles and are secured to an existing building so that the existing building is supported by an array of the deeply driven pipe piles which serve as the foundation for the building. Alternative pile cap connectors are length adjustable to span the distance between the top of the drill driven pipe piles and the underside of the lifted existing building. The pile cap connectors are an integral part of a method using low-overhead equipment to construct a deep piling foundation for an existing building where the method involves lifting the existing building to a predetermined elevation above grade and positioning cribbing stacks to support the existing building at the predetermined elevation above grade. The cribbing stacks are spaced from each other enabling low-overhead equipment to maneuver underneath the elevated building to drill drive the pipe piles at designated locations to provide optimal support for the building.
