In general, we recommend testing on a new site all the deep pile foundations on site. This is because the cost of the test relative to the damage it may save makes no sense in doing otherwise. If you need to test a pile understructure of an old building, you need to consider additional factors, like building age, reliability of available data on the foundations, and how well the tested results correlate with that data and planned changes to the building or structure, and their use.
