This document provides summary information for users of BGS Civils, a suite of seven engineering properties datasets. These comprise the following engineering geoproperty information:
- Excavatability
- Strength
- Discontinuities
- Bulking of soils and rocks
- Sulfate and sulfide potential
- Corrosivity (ferrous)
- Use for fill
Each dataset has an accompanying User Guide, which details the content and development of each engineering property dataset. These documents are summarised in this report.
This document outlines the background to why the dataset was created, its potential uses and gives a brief description of the content. Technical information regarding the GIS files and how the data was created is described and advice is provided on using the dataset.
The information is primarily for the near surface, here defined as the top 2 m, but will have application to greater depths for many geological units where it occurs below this depth. This data ‘product’ has been driven by a perceived need and has been made possible by the increasing availability of ground investigation borehole and pit records, and the geotechnical data from the National Geotechnical Properties Database (Self et al. 2012[1]). These provide the sources of data for the engineering properties, geological maps, reports and other documents, within the context of the spatial distribution of geological units across Great Britain. The need for this type of information was initially identified during work for the management of buried utilities, but equally, the information could prove useful to other industries such as civil engineering, the extractive industries, planning and development as well as answer more strategic legislative requirements such as the soil-framework directive.
The dictionaries, and terminology used are in accordance with standard engineering vocabulary as recommended in EuroCode7-2 (BSI 2007[2]) and BS5930 standards (BSI 2003[3], BSI 2015[4]).
The methods used to create the dataset have been critically assessed for fitness for purpose by experts in BGS.
