Foundtest (M) Sdn. Bhd. is
specialized in providing high strain dynamic load testing, analysis
and consulting services for the piling work industry. Dynamic pile
testing (commonly known as PDA test) is performed by well-trained
and experience engineers using a Pile Driving Analyzer (PDA)
on site and pile wave analysis will be carried out on the signal
acquired by using Case Pile Wave Analysis Program (CAPWAP).
Dynamic pile testing technology
had been introduced to the industry for more than 30 years. This
time and cost saving method of pile testing has eventually getting
popular and is widely recognized nowadays. The American Society of
Testing and Materials has developed a standard (ASTM:D4945) for the
performance of dynamic load test. It is a very cost-efficient tool
used to replace the time consuming conventional
static load test in
determination of pile capacity.
PDA is a very powerful tool in monitoring the
response of a pile subjected to hammer impact applied at the pile
head. The response is measured in terms of force and acceleration
close to the pile head. Other than determination of pile capacity,
the behaviour during the pile installation works, such as the pile
integrity, driving stresses and the energy transmitted to the pile.
Once the pile wave analysis is completed, the full report will
present the predicted static load-settlement behaviour and the pile
capacity distribution among the pile shaft and pile toe. All these
information are very useful in assessment of the pile capabilities
by the engineers.
