Pile load testing services is an important factor for the piling works that should be properly planned and factored into the project schedule and project costs at an early stage in order to validate the design safety factors, pile design & lengths, to establish the pile installation criteria and to quality control the piling works.
Static pile load testing (axial and lateral)
Dynamic compression load testing by pile driving analyzer (PDA)
Pile integrity testing (PIT)
STATIC PILE LOAD TESTING
The test procedure is based on the direct measurement of pile head displacement in response to a physically applied load. The test pile is loaded using a calibrated hydraulic jack that applies the test load to the pile by pushing against a beam placed directly over the test pile. The test beam is restrained by an anchorage system consisting of reaction piles installed in the ground to provide tension resistance. Once the load test frame is installed and fully instrumented, the hydraulic jack applies the test load in a series of increments according to the testing requirements as per project specifications. Each load is held for a certain amount of time until either twice the design load or pile failure is reached, whichever comes first. Pile movement is recorded with each incremental load.
Piles can be tested for compression, tension or lateral loads. By providing actual capacity and deflection values, the test results can be used to confirm that the pile design load can be adequately supported. Depending on the test pile’s performance, the results may also allow for project cost savings by permitting an increase in the pile design load, a reduction in the overall pile length, or a quantification of capacity in difficult or unknown soil conditions.

DYNAMIC COMPRESSION LOAD TESTING BY PILE DRIVING ANALYSER (PDA)
Dynamic load testing of piles by Pile Driving Analyser (PDA) is a fast and effective method of assessing foundation bearing capacity that requires instrumenting a deep foundation with accelerometers and strain transducers (sensor) and analysing data collected by these sensors. PDA testing can be undertaken during initial driving or during re-strike drives after allowing soil setup on the pile for a suitable period of time. in order to verify pile resistance, CAPWAP analysis is performed on field data from a selected representative hammer blow from the PDA test record and the following information on the pile resistance can be derived:
Pile load bearing capacity
Skin friction distribution over the pile length and the end bearing capacity
Prediction of load-settlement chart
Evaluation of pile integrity
Hammer performance
Maximum driving stresses
PILE INTEGRITY TESTING (PIT)
Pile Toe Level
Shaft restraints
Cracks
Reductions in section
Zones of poor quality concrete
The test method is performed with a hand held hammer, a sensitive accelerometer and the Pile Integrity Tester. The accelerometer is attached to the top of the pile, and then a compressive wave is generated by tapping the pile head with a hammer. When the downward compression wave encounters a change in cross section or in concrete quality, it generates an upward tension wave that is later observed at the pile top. The velocity recorded along with the subsequent reflections from the pile toe or pile discontinuities are graphically displayed. The effectiveness of the system is limited to a pile length not exceeding (30 to 60) * pile diameters depending on soil condition and concrete quality.
