Pile integrity testing using low-strain tests such as the TDR (Transient Dynamic Response) method, 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
Dynamic load testing (or dynamic loading) is a method to assess a pile's bearing capacity by applying a dynamic load to the pile head (a falling mass) while recording acceleration and strain on the pile head. Dynamic load testing is a high strain dynamic test which can be applied after pile installation for concrete piles. For steel or timber ...
These sensors are connected to an instrument (such as a pile driving analyzer), that records, processes and displays data and results. As long as the wave travels in one direction, force and velocity are proportional and related by the expression F = Zv, where: Z = EA/c is the pile impedance; E is the pile material modulus of elasticity
In the U.S., the Federal Aviation Administration recommends eight hours between drinking and flying and that employees be removed from their duties if their blood alcohol concentration registers 0 ...
Bi-Directional Static Load Test is a steadfast Maintained Load Test option for both large and small diameter piles that is widely used in the market. The main difference between a top-loaded maintained load test and a Bi-Directional is the location of the jack. One of the types of bi-directional method is YJACK method. [4]

A pile or piling is a vertical structural element of a deep foundation, driven or drilled deep into the ground at the building site. Deep foundations of The Marina Torch, a skyscraper in Dubai. There are many reasons that a geotechnical engineer would recommend a deep foundation over a shallow foundation, such as for a skyscraper.
