Pile Profile Tests
SoniCaliper or Shaft Area Profile Evaluator (SHAPE) method are cost-effective and are used as quality assurance testing instrument and device. Usually to determine the excavation dimensions and verticality/stability. They are also often used for deep foundations excavations such as drilled shafts, slurry walls, barrettes etc. Whereas, Koden test, based on ultrasonic distance measurement, is used to inspect the verticality, diameter / bell-out diameter of the pile hole (dropping down an instrument along the pile hole to the bottom).
