auger cast grout piles
how many piles should be set aside at the begining, to be used for load tests before the execution phase of the construction of the deep foundations?
5% for all under 45 cm diameter
10% for all between 45 aln 100 cm
25% for all over 100 cm
must be tested in one or other way for "in situ" piles according to cte.
however need not be load tests, (but integrity, sonic etc) for which a percentage is not set. for big numbers of piles in an "uniform" soil 1 to 3% should be more than enough.
