Engineering Properties:Bulking

This dataset is a characterisation of the soil and rocks and the potential bulking factor (likely excavated volume increases) at Formation (local to regional) level for Great Britain. The data is categorised into Class, characteristics of similar soils and rocks and Bulking Factor, range or ranges of % bulking. The excavation of rocks or soils is usually accompanied by a change in volume. This change in volume is referred to as ‘bulking’ and the measure of the change is the ‘bulking factor’. The bulking factor is used to estimate the likely excavated volumes that will need to be moved, stored on site, or removed from site. It is envisaged that the 'Engineering Properties: Bulking of soils and rocks' dataset will be of use to companies involved in the estimation of the volume of excavated material for civil engineering operations. These operations may include, but are not limited to, resource estimation, transportation, storage, disposal and the use of excavated materials as engineered fill. It forms part of the DiGMap Plus dataset series of GIS layers which describe the engineering properties of materials from the base of pedological soil down to c. 3m depth (ie the uppermost c.2m of geology). These deposits display a variable degree of weathering, but still exhibit core engineering characteristics relating to their lithologies.

Statement

The source data for this dataset is based on the digital geological map of GB (DiGMapGB-50) which has been processed to create the Parent Material Map (PMM) V6 at 50K scale. This provided the underlying geology areas (polygons). The geology has been reattributed using a set of engineering properties. In the absence of primary bulking factor data from site investigations, bulking factor values were sourced from a variety of published literature. Categorisation of the data, and assessment of the bulking factor values of rocks and soils within the GB, has been made by expert judgement in order to create 'look up tables' of rock/soil type and associated engineering properties. The DiGMapPlus datasets follows a standard workflow to create each dataset: - Step 1: Identify characteristic, measurements and observations from archive records. - Step 2: Categorise the observations into classes/groups of similar behaviours. Where possible using published standards of classification such as BS 5930, Eurocode 7 or other similar international or national standard. - Step 3: Assess the range of variation of geological materials across Great Britain, in terms of the categories and classes identified in step 2 to create a 'lookup' dataset of expected attributes (material characteristics and behaviours) per rock/soil unit. - Step 4: Compile the spatial (map) components of the DiGMapPlus datasets with the 'lookup' dataset using standard GIS and data techniques to create a new 'map' of bulking characteristics. Spatial data-creation and bulking attribution has been completed using ESRI ARCGIS software.
