BGS Civils is a suite of maps of engineering properties based on the 1:50 000 scale Geology map  of Great Britain. It comprises eight layers and provides the key engineering characteristics of the  uppermost 2-metres of geology of Great Britain:

  - Bulking Volume (increase in volume when excavated)
  - Corrosivity (Ferrous)
  - Discontinuities
  - Engineered Fill
  - Foundation Conditions
  - Excavatability
  - Strength
  - Sulphate/Sulphide

The dataset is intended for professional user desk studies in engineering, environmental consultancy, planning, site development and asset management for daily planning activities and preventative maintenance or investigating costs for trench excavation.
