Many thanks to all those who have responded to my query below – very helpful.
Dear All – I have a question related to minimum acceptable percentage trenching sample to evaluate a greenfield site. The figure of 5% was used a lot in the past but is such a small sample still generally considered to be usefully valid? Can’t find anything in the CIfA or ALGAO libraries to update me so would be grateful for any help and useful (on-line) references.
