Pile Integrity Test (PIT)
ASTM D5882 defines the Pile Integrity Test (PIT) as a non-destructive procedure for evaluating the condition and continuity of cast-in-place piles and drilled shafts. The test employs low-strain impact waves generated at the pile head, with the reflected signals evaluated to detect abnormalities such as fractures, necking, or changes in pile cross-section. PIT is a rapid and inexpensive approach to assess pile integrity after installation, particularly in quality assurance procedures. It is an effective method for spotting building problems early on, reducing risks and maintaining structural reliability.
