Static load tests were performed during the test phase of contract to verify the design assumptions and load-carrying capacity of the piles. Telltale rods installed at various depths within the piles were used to evaluate the load transfer behaviour of the piles with regard to the surrounding soil and bearing stratum.
The bearing capacity is depending on the size, shape and type of pile and on the properties of the soil in which it is embedded. The ultimate bearing capacity is the load at which the resistance of the soil becomes full mobilized. At the load greater than bearing capacity, this causes the head of the pile to settlement 10% of pile diameter.
General pile load test on Preliminary (Non-working) and Working piles are to be carried out as per requirements of the specification. The test load on Preliminary Pile and Working Piles are defined in the specifications.
The test assembly consists of the following:

PDA Testing utilizes the Pile Driving Analyzer (PDA) and is based on the theory of Stress Wave Propagation on Piles (CASE Method). Force and measurements taken near the top of a pile during impact provide the necessary information to determine:
