How do you check for pile integrity?
Pile Integrity Test (PIT) is normally performed by striking the pile head with a light hand-held hammer and recording the response of the pile using a motion transducer (i.e. accelerometer) coupled to the pile head. The hammer strike (blows) generate compressive stress wave that will travel through the pile.
How many piles are integrity tested?
The pile head shall be fr ee from water, dirt or other debris. The concrete at the pile top surface must be relatively smooth and provide sufficient space for attaching the motion sensing device and for the hammer impact area. _____% (20%, 50%, ___%, 100%) of all piles shall be integrity tested.
What is an integrity test?
An integrity test is a specific type of personality test designed to assess an applicant’s tendency to be honest, trustworthy, and dependable. A lack of integrity is associated with such counterproductive behaviors as theft, violence, sabotage, disciplinary problems, and absenteeism.

How do you measure integrity of concrete?
Methods for Testing Compressive Strength of Concrete
- Rebound Hammer or Schmidt Hammer (ASTM C805)
- Penetration Resistance Test (ASTM C803)
- Ultrasonic Pulse Velocity (ASTM C597)
- Pullout Test (ASTM C900)

How is pile depth measured?
DIRECTIONAL DRILLING/SHEET PILE LENGTHS If a 2 inch PVC lined hole can be provided, a down hole magnetic gradiometer can be used to determine the depth to the end of the pile. If a hole cannot be drilled or is not available, pulse echo measure- ments can be made.
What is integrity of concrete?
Introduction. Structural integrity is the ability of a structure to withstand its intended loading without failing due to fracture, deformation, or fatigue. It is a concept often used in engineering to produce items that will serve their designed purposes and remain functional for a desired service life.
What is core test for concrete?
Core test is a well-established method, generally performed in the area of concrete industry to assess whether the suspect hardened concrete complies with strength- based acceptance criteria or not; and sometimes it becomes the unique tool for safety assessment of existing concrete structures.
