Initial Site Appraisals
Initial site appraisals save money, and they often save time too! How?
By enabling proper planning of an appropriate investigation so that subsequent decisions regarding site acquisition, development
or disposal are soundly based.
Our initial site appraisals, also often called desk studies, Phase 1 or preliminary investigations, are designed to meet the
core requirements of the major relevant standards (see References table below) whilst, by offering a range of optional extensions
to scope, we provide the client with the flexibility to tailor the scope of the appraisal to suit the nature of their project
and the level of information required.

The data sources considered by the desk study include:
- Geology - British Geological Survey (BGS) mapping
- Radon status and protection
- Statutory authorizations, consents and determinations
- Incident notices/prosecutions and registers
- Environment Agency and Local Authorities
- Landfill and other waste sites
- Ecological designated sites (sensitive land uses)
- Client's own information
A walkover survey provides further valuable information about the condition of the site and its environs.
Our initial site appraisal reports provide a Conceptual Ground Model and an evaluation of the findings together with a photographic
record of current features of interest/concern, topographic maps, geological maps and all the database search results.
OPTIONAL EXTENSIONS TO SCOPE
|
- BGS borehole records – Available borehole logs are purchased and reviewed
- Full reports, when relevant, from databases of coal mining, natural cavities
and non-coal mining
- Soil type – Soil Survey of England & Wales mapping
- Aerial photographs, including ‘cover’ search, purchase and interpretation
- Manual searches of reference material in county records offices, libraries,
museums and local history sources

Health, Highways)
