Site Investigation
A geoenvironmental intrusive site investigation is normally carried out following the conduct of a desk study and liaison with the regulators in order to help clarify the level of risk or appropriate mitigation measures. In addition to intrusive works such as trial pits or boreholes and any associated testing or monitoring a site investigation will include a revision of the conceptual site model as derived by the desk study, an updated risk assessment and associated recommendations. A geotechnical site investigation is carried out to clarify appropriate foundation design and may also include the inspection of any existing footings on site. It should be noted that site investigation is an iterative process.
