Duong Do “A frame is assembled over the pile to be tested on top of which an amount of weight (a minimum 110 to 120% of maximum test load) is safely stacked. This generally takes the form of concrete blocks of regular dimensions and weight although steel ingots can be used provided that their weight can be assessed with reasonable accuracy. The size of the testing apparatus is generally a function of the pile size … Read more

PileDynamicsInc SQUID performs a quantitative assessment of the bottom surface of a drilled shaft – quickly, safely and efficiently. Measuring the thickness of sediment covering the bearing strata, it outputs strength vs penetration analysis.
Dan Brown and Associates Lateral Statnamic load test on an 8-ft drilled shaft in the St. Croix river near Oak Park Heights and Stillwater, Minnesota. Approximately 220 tons of force are applied.
Skfycraftmedia’s channel Aerial view of a Statnamic load test on a deep foundation. “The Statnamic is a Rapid Load Test that uses a combustion chamber to provide a rapid load application to the pile head. The length of the stress wave in these tests is sufficiently long to encompass the whole pile and therefore there is no need for complex wave equation analysis when interpreting the results. However, in common with the dynamic load test, … Read more
The kentledge method is a static load test for piles where a frame is assembled over the pile to be tested, on top of which an amount of weight (concrete blocks in most cases) is safely stacked. In this particular project the operation was not that safe… SPH Razor 154thmedia
Shannon Theodore The Thermal Integrity Profiler (TIP) uses the heat generated by curing cement to asses the concrete quality drilled shafts or augered cast in place plies.
These methods are based on monitoring the response of a pile subjected to hammer blows applied at the pile head. The measured response parameters are subsequently analysed to give predictions of the soil resistance that would be mobilised by the pile under static load conditions, based on stress wave theory.

Shannon Theodore The Cross-Hole Analyzer determines the quality and consistency of the concrete of drilled shafts, slurry walls, bored piles, cast-in-situ piles and other types of concrete foundations.
Handbook on Pile Load Testing Federation of Piling Specialists. “Pile load testing provides an opportunity for continuous improvement in foundation design and construction practices, while at the same time fulfilling its traditional role of design validation and routine quality control of the piling works. In order to achieve this improvement, data from pile tests has to be collected and analysed to enable the piling industry, both individually and collectively, to make the best use of … Read more
