Site Investigation Services / Phase 2: Intrusive Investigation Reports

Great projects grow from information you can trust.

Arc Environmental will help you uncover the history of a site or a building, bringing to light previous use.

Our site investigations ranging from non-intrusive surveys to in-depth research of ground conditions.

We will use a variety of complex techniques and equipment, ranging from geophysical investigation to trial pitting and boreholes. Our reports and advice are user-friendly and accessible to a wide range of professionals including architects, surveyors, agents and lawyers.

Our interpretive reports will assess soil and groundwater contamination, ground gas issues, the presence of mine workings, the groundwater conditions and geotechnical information to aid with foundation and pavement design.

Many of our investigations are conducted to discharge contaminated land planning conditions and we ensure we have regular liaison with the regulatory authorities.

All our intrusive investigations adhere to well defined health and safety practices, and use site specific method statements and risk assessments, on-site service information and liaison with statutory authorities.

All our site investigations and associated soil and rock logging are carried out in accordance with relevant Eurocodes and British Standards.
