Phase 1: Desktop StudySWEL will undertake a phase 1 desktop study in any part of the UK. This will be a 30 page report written by a geologist and will be tailor written for your site. SWEL guarantee that your district planning authority's content requirements for a desktop study will be met.
A Phase 1 Desktop Study (see an example desktop study) is often required by local planning authorities, when applying for planning permission. New build and change of use both require planning and therefore a Phase 1 Desktop Study to be compiled (desktop study contents), SWEL will undertake a desktop study in any part of the UK.
As well as outlining Environmental Risk a Desktop Study also informs of Geotechnical related risk on the site, known occurrences of subsidence, and man made ground etc. are detailed in the report.
Desktop Study FAQs
contaminated from historic or present day activities. So unlike a Site Investigation a Desktop Study uses a "Reading" approach rather than a "Digging" approach. A step by step "How it Works"
1 - You give us the "go-ahead".
2 - We collect data on your site. Maps, Pollution Incidents etc.
3 - We visit your site to conduct a walkover survey.
4 - We write the report.
5 - We conclude the report with recommendations as to the risk posed by contaminated land (if any) to future inhabitants, and sensitive receptors in the area. A receptor is anything that may be impacted on by contamination, a river, a tree etc.
The first discussion is always free, so drop us a line / call with any questions.
Elaboration based on two examples:
1 - Petrol Station with Workshops: Walkover Survey will involve entering building, looking down man hole covers, looking in cupboards etc. Surplus to usual secondary information Data will have to be sought from Local Council to confirm / disconfirm the presence of buried tanks.
2 - Back Garden: Will only require the simplest of walkover surveys, and no extra secondary data will be needed (in most cases).
We are sorry we can't give a fixed price, but we only need a little bit of information about your site to give you a quote. Give SWEL a ring and we will give you a price instantly, which we will then follow up with a formal quotation, if the price is to your liking!
The outcome of the study is 80% of the time fairly easy to predict if you have a study on a;
i) Petrol Station: Then the outcome of the study will almost certainly recommend further work, namely a Site Investigation. This might equally apply to disused factories, or workshops.
iii) Open plot within an Urban Setting: This type of scenario could go either way. Was it allotments or was is a foundry. Only a desktop study will reveal the sites past contamination issues. It is this instance (iii) when a Desktop Study is most useful. So in short you may a have a little worry, but land contamination can in 19/20 cases be adapted to, and if it does turn out that your land is contaminated, it doesn't mean you won't be able to build on it (unless its really bad) and solutions can be found. For a free initial consultation ring / email the office, and we can answer any question you may have. Environmental Consultants.
1- The Report: It is stipulated in Government Legislation that only a qualified person can make recommendations on brown field development, a SWEL desktop study is only ever assembled by a qualified geo-scientist. In the desktop study there is various generic information regarding to the site, a risk assessment, and recommendations, which will say whether SWEL Environmental Consultants recommend that your build / planning approval go ahead, or that there is a site investigation leading to a quantitative risk assessment. Photos: Photos of the site, especially problem areas, if there are any.
2 - Maps: Historic Maps, Geological Maps, Geo-hydrological Maps, Site Location Maps, Arial Photos.
3- Conceptual Models: Various models are included visually explaining how you site may interact with the environment. The first discussion is always free, so drop us a line / call with any questions.
The bottom line!
Certainly less than £1000, unless you site is very big. We only need to know the most basic of details to provide a quote so please call us.
A desktop study would normally precede a site investigation and many would argue that it is essential. However, production of a formal report can be avoided if it deemed necessary to undertake a site investigation. Some site such a petrol stations and scrap yards will definitely need a site investigation. So it would seem surplus to requirements to produce a formal desktop study report. However there should always be a desktop element within the site investigation, underlying geology, location of potential hot spots, made ground can all be identified via desktop study, and as such a review of available data should be included whether this forms part of the desktop study or part of the site contamination assessment report.
Most of the desktop studies undertaken by southwest environmental are for planning applications, whether if these applications relate to a new project or change of use.
However desktop studies are also used in some other areas of our work namely site condition reporting for environmental permits. When used in site condition reporting there are used to assess likely ground quality, and provide a qualitative baseline for soil quality at the time of reporting.
