What is PAS 128?

PAS 128:2014 is the latest specification for underground utility detection. The purpose of the PAS 128 specification is to set out clear requirements when carrying out the detection, verification and location of active, abandoned, redundant or unknown utilities. It applies in all areas that any utilities are present and are no deeper than three metres underground (for example in urban or rural areas, in the street, or private sites, such as hospitals or airfields).
