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. Bearing capacity and other pipe pile characteristics that indicate whether the pipe pile tested is acceptable are determined from the information provided by the sensors."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"High strain dynamic load testing procedure","description":"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.
