Phase 2 Site Investigation

Phase 2 Intrusive site investigations are principally progressed if the results or recommendation of a Phase 1 Desk Study & Site Walkover present the need for further investigation. The site investigation is designed to confirm ground conditions and target areas of concern based the risks of contamination associated with the site and frequently the adjoining area found in the Phase 1 study.

Hydrogeo are highly experienced in scoping, organising and undertaking intrusive ground investigations on an extensive range of sites and projects. We work with our clients and the statutory consultees to ensure that the site investigation is designed to fulfil the project objectives and gather the necessary data to satisfy the investigation.

Site Investigations are carried out in accordance with Environment Agency LCRM and relevant British Standards. For contaminated land sites, the data collected during an intrusive site investigation is utilised to update the site conceptual model, progress quantitative risk assessments and where required inform a site remediation strategy.

Hydrogeo employs a range of intrusive and non-intrusive techniques to undertake ground investigations. These include traditional techniques such as trial pitting, window sampling, cable percussive and rotary borehole advancement in order to retrieve soil / rock samples. Samples are logged to confirm the underlying strata and sent to a UKAS accredited lab for soil chemical analysis.

Staff undertaking ground investigations are graduate engineers with appropriate qualifications, experienced in geological disciplines, and hold current CSCS cards.
