How long does a typical soil investigation project take in London?

Simple surveys may complete in days, while large multi-location projects can extend to several months. Weather conditions and London's traffic can occasionally impact scheduling.
What certifications should soil investigation contractors hold?
Reputable London contractors should hold membership with the Engineering and Physical Sciences Research Council (EPSRC) or equivalent, plus CHAS or Constructionline accreditation for safety compliance. Geotechnical engineers should be registered with relevant professional bodies like the ICE or BGA to ensure competency standards.
