So many factors influence the performance of a pile such as settlement, earth movements and potential earthquakes, so no company should take risks on something as preventable as pile integrity. A Qualified 3rd Party Company can ensure tests are carried out correctly, to save time and money, on construction projects. If undertaken correctly (i.e following AS-2159), PIT and CSL can provide similar calibre results as other test methodologies (when applied correctly) at a fraction of the cost. Best practise testing, uses various robust methods, including:
– High-strain and low-strain tests complement each other, making it advantageous to utilize both. Conducting high strain tests on 5% of piles and low strain tests on 25% of piles would provide the engineer with enough confidence in structural guarantees to ensure the area pertains a structurally sound base.
– Static load and dynamic tests provide knowledge about load strengths and pile resistance at the toe and skin.
– Low strain tests provide information about pile integrity in relation to shape, defects, and concrete quality.
– Whilst only one or two piles may be tested in a day with high strain methods (not including pile preparation, and organising a drop weight and permits), low strain methods can be performed on more piles in a single day and to a higher percentage of total piles tested.
Example: PIT can be conducted in the realm of 20-40 piles per day depending on access to pile tops and data quality. Additionally, CSL can be performed on as many piles as 10 per day, ensuring the cages have been installed with access tubes.
