Desk Study

A Desk Study is the first step in the iterative process of Contaminated Land Assessment.  It involves a site walkover and the review of publicly available information for a given site, including past and current uses as well as surrounding land use in order to develop a conceptual site model upon which of a risk assessment is based to consider the potential sources of contamination identified.  A Desk Study is normally carried out prior to the conduct of any intrusive site investigation since it forms the basis upon which the site investigation is conducted.  

Geo-Environmental Site Investigation

Intrusive Geo-Environmental Site Investigation forms the second phase of the iterative contaminated land assessment process and aims to investigate each potential source of contamination that has been identified by the Desk Study. Therefore each site investigation must be bespoke and designed to target the particular issues at each site in relation to the proposed development based on the Site Conceptual Model that has been derived from the Desk Study.

Geotechnical Site Investigation

Geotechnical site investigations are required to provide a thorough understanding of the ground conditions at a given site and provide recommendations for suitable foundation design of proposed structures. We aim to undertake an integrated approach to geotechnical investigations and desk study based research is carried out prior to any intrusive work to help ensure that we are prepared for the ground conditions present and anticipate the geotechnical information that will be required to enable the design of appropriate foundations.

Land Remediation

Contaminated land remediation work comprises the third phase of the contaminated land assessment and may be required to help mitigate risks associated with the presence of contamination that has been identified during the Geo-Environmental Site Investigation. Prior to the conduct of remedial works a remedial strategy should be designed and fully documented within a site specific Remediation Method Statement (RMS). This document sets out the preferred remedial method to be employed, targets to be achieved, how the site will be validated and any monitoring requirements. Following the completion of remedial works a Validation Report should be produced to document the remedial works undertaken and to conclude whether they were successful.

Ecological Surveys

A robust ecological assessment of a development project is based on a comprehensive set of ecological information specific to the site in question.  Gathering this information is generally undertaken in three iterative steps comprising firstly the conduct of a desk study, then if required an extended phase 1 habitat survey and then subsequent detailed habitat and species surveys in order to inform the requirement for mitigation measures.  It is necessary, from the earliest stage in a proposed development project, for the design team to be fully informed about the presence or potential presence of statutorily protected species on or around the site.  Disturbance of interference with protected species can constitute a criminal offence. Our ecologists are highly experienced not only in the technical skills of site surveys, but also in working within multi-disciplinary teams and regularly provide expert advice to help overcome obstacles to development associated with the presence of protected species. 

Flood Risk Assessments

In circumstances where the Environment Agency consider that there is a risk of flooding they may require the conduct of a Flood Risk Assessment to accompany a planning application. A Flood Risk Assessment takes into account the risk and impact of potential flooding on a site as well as how the development may affect flooding in the local area.  It provides recommendations as necessary as to how the risks associated with flooding can be managed.  Each assessment undertaken is specific to each individual site and can range from the most basic level of report through to a detailed flood risk report including mitigation works. 

Asbestos Surveys

Under the Control of Asbestos Regulations 2006, owners of non domestic buildings have the responsibility to manage asbestos in premises.  As such, asbestos surveys are carried out to comply with this legislation.  Surveys are also required before the demolition or refurbishment of buildings.
