Service Focus:

Desktop to Phase 1 services

Reports for site analysis and environmental assessment provides datasets and reports for all stages of site development from locating a site through to full Phase 1 studies.

Here we look at some of the most common datasets and reports our users draw upon to mitigate risk and realise the greatest potential from their development site.

Read on for our quick run through for:

  • Contaminated Land Assessments
  • Flood, Environmental and GroundWater Assessments
  • Sustainable Drainage Reports (SuDS)
  • Utility Searches
  • Geological Data
  • Base Mapping

Utility Searches

 utility searches from - PAS128 compliant reports in PDF or converted to CAD ensure you're aware of critical infrastructure in the vicinity of your site and can guard against unexpected costs and risk to personnel's health and safety

Utility Searches

Critical to site design and risk avoidance for health and safety and damages liability. Even "green field" sites can carry gas pipelines or fibre-optic cables for example.

The Utilities Search Report collates and outlines features below the surface such as:

  • gas and oil pipelines
  • electricity cables
  • telecommunication wires
  • mains water supplies
  • sewers
  • fibre-optic cables.

Overview maps available in CAD format, for review alongside your other site designs.

From £369.25 + VAT including disbursements


We also offer underground services tracing at survey level accuracy for non public areas and verifying data from statutory searches.

Geological Data

 Geological data from ranges from bedrock and superficial geology to borehole records. Interpreted datasets such as the BGS Civils data offer relevant information to designing infrastructure and recognising how the environment will behave in both the short and longer terms

BGS (British Geological Survey) data covering both bedrock and superficial geology and also derived datasets such as the Civils collection.

  • Boreholes: Free to view on Under "extras", find markers showing all BGS borehole records coloured by depth. Links to an online PDF copy of the trial pit / borehole log.
  • 50k and 10k geology: Providing bedrock and superficial geology. Available in layered PDF or CAD/GIS formats including links to the detailed listing in the BGS lexicon
  • Civils: a comprehensive collection focussed on civils requirements covering:
    • Bulking Volume
    • Corrosivity (ferrous)
    • Discontinuities
    • Engineered Fill
    • Excavtability
    • Foundation
    • Strength
    • Sulfate/Sulfide potential

Boreholes - FREE. Other datasets from £10 + VAT

 Base Mapping delivers base mapping in convenient formats making it quick to consume and support your site assessments whether it be raster mapping, PDF report, vector extracts or height data as points, grids or contours, we have a range of data to help you quickly establish you site's environment
