Intrusive Site Investigation for a Housing Development
Current government guidance requires all proposed housing development sites that are potentially contaminated to undergo a Preliminary Risk Assessment to identify the potential risk from land contamination. As in the case study on this page, this assessment may conclude that further testing is needed in order to determine the levels of risk present at the new build site, this is the point when a Phase 2 Intrusive Site Investigation should be carried out for a housing development.Get In Touch
What Does an Intrusive Site Investigation for New Build Housing Development Involve?
Phase 2 Intrusive Site Investigations for new build housing developments allow the assessor to measure the levels of contamination in the ground and therefore assess the risk to nearby receptors (i.e. residents, water bodies, wildlife etc). An Intrusive Site Investigation for a housing development will generally involve a site visit to take soil samples and assess the ground conditions, chemical analysis of the samples and comparing analysis results with industry standard screening levels.
Intrusive Site Investigations for new build houses may be done for a range of reasons based on different specific requirements and desired outcomes and each project will be very specific to each individual case. For example, the scope of work for an Intrusive Site Investigation requested through a condition on a planning application for new build houses may be different to that of an Intrusive Site Investigation used for land valuation when buying/selling land for a housing development. Housing developments are particularly sensitive sites because of their residential end use and this means it is especially important to ensure that the land being built on is free from contamination and an Intrusive Site Investigation is the only way to determine whether contamination is present at the site of a new build housing development.
Case Study for a Phase 2 Intrusive Site Investigation for New Build Houses
Our client's proposed project involved the construction of 10 residential dwellings along with a block of serviced apartments on the site of abandoned plant nurseries and an active storage and logistics yard. A Phase 1 Desk Study identified multiple contamination sources from the previous uses of the site and recommended that a Phase 2 Intrusive Site Investigation would be needed in order to more accurately assess the contamination risks at the site. When a site is proposed for residential use the acceptable risk levels from land contamination are particuarly strict, especially when applying for planning permission so it is common for a Phase 2 Intrusive Site Investigation to be needed for a housing development of this kind.
How We Helped - We were able to visit site to carry out intrusive soil sampling for the housing development project, send the samples to a UKAS accredited laboratory for chemical analysis and write up a comprehensive site investigation report. After analysing samples we compared them to industry standard screening levels and found that there were sources of heavy metal and hydrocarbon contamination at the site. This allowed us to provide well informed recommendations for how to proceed with the housing development project.
