Pile Foundation Test Plans

The following test are conducted and analyzed as per requirement by NS Engineering and Geo-Technical Services:

 

  1. Static Load Test:

Static Load Tests measure the response of a pile under an applied load and are the most accurate method for determining pile capacities. They can determine the ultimate failure load of a foundation pile and determine its capacity to support the load without excessive or continuous displacement.

 

  1. Pile Dynamics Analysis (PDA):

PDA systems evaluate bearing capacity, shaft integrity, driving stresses, and hammer energy when monitoring installation. PDA tests are performed during driving on pilot or production piles, taking advantage of the high strain impact provided by the driving hammer.

 

  1. Pile Integrity Test (PIT):

Pile integrity test is a rapid way of assessing the continuity and integrity of concrete piled foundations. The test measures, pile length, or depth to anomalies, pile head stiffness, pile shaft mobility, which is dependent on pile section and concrete properties.

 

  1. Cross hole Sonic Logging (CSL) Test:

Cross hole Sonic Logging (CSL), also known as cross sonic logging or the sonic logging test is the most accurate and reliable technique for assessing the integrity of deep foundation elements such as newly placed concrete drilled shafts and slurry walls, particularly when drilling below groundwater level.

 

  1. Lateral Load Test:

The initial lateral load test for piles shall be conducted after 28 days of lateral load test pile casting by obtaining a reaction from the concrete blocks or adjacent piles.  A horizontal support beam or truss should be fabricated to receive its lateral test load through a horizontal loading platform firmly placed over the compacted ground or adjacent pile. This test provides lateral displacement of the pile tested.
