ABSTRACT
Site investigation is a widely used term and is often taken to mean physical exploration on site, such as the excavation of trial pits or the sinking of boreholes. It is, perhaps, for this reason that all too often investigators charge onto site with no real understanding of what they are looking for or why. Such investigations can often end up as nothing more than the examination of a number of unrelated points of detail with no coherent strategy or means of interpretation.
