Rows of empty sample jars for use in site investigations


Site investigations and ground investigations are an essential part of land development. They enable designers to determine geotechnical properties of the ground to aid in foundation design and to determine the presence of any harmful contamination in soil or groundwater to assess risks and determine remediation requirements. 


ERS's multi-disciplinary team of geologists, drillers and scientists undertake and manage site and ground investigations on behalf of designers, consultants, developers, local authorities and smaller clients to provide factual reports. We've also done several projects for renewable energy consultants and developers, including work on solar farms, battery energy storage systems (BESS) and other energy infrastructure projects. Whilst we mainly work across Scotland and the north of England, as contaminated land specialists, we are often asked to work further afield too. Take a look at our Projects page for examples of some of the sites we have worked on.


We carry out our work in accordance with BS EN 1997-2 and its related technical standards together with the relevant sections of BS 5930 and ERS’ own in-house procedures.  Where applicable, ERS conducts all ground investigations in accordance with BS 10175. 


Our capabilities include the undertaking and supervision of trial pitting, windowless sampling drilling, cable percussive drilling, rotary core drilling with dynamic sampling and sonic drilling, soil resistivity testing for electrical infrastructure, and the installation of gas, vapour and groundwater monitoring wells. Our experienced geologists log soils and rock samples to BS EN 14688-1 and BS EN ISO 14688-2 to provide engineering logs of trial pits and boreholes. 


Our team also undertakes in-situ testing including infiltration testing (BRE 365) and dynamic cone penetrometer (DCP) testing, resistivity surveys and site monitoring and sampling. ERS will also manage the transport and storage of samples collected during the site investigation and schedule geotechnical and geotechnical testing with external laboratories. 


As brownfield and contaminated land specialists, ERS has experience of site investigations on more complex and heavily contaminated sites, e.g. BDA Red Sites, and apply appropriate mitigation measures to protect site staff and the environment during the works.
