The values supplied are the indicative minimum, maximum and typical values we would normally expect to encounter per geological unit but limited to the top 2\u20133&nbsp;m.<\/p>\n\n\n\n<p>The spatial model covers England, Scotland and Wales at 1:50&nbsp;000 scale and is based upon bedrock and superficial geology from BGS Geology 50K, archive data of engineering soil strength from the <a href=\"https:\/\/www.bgs.ac.uk\/geological-research\/science-facilities\/engineering-geotechnical-capability\/national-geotechnical-properties-database\/\">National Geotechnical Properties Database<\/a> coupled with the <a href=\"https:\/\/www.bgs.ac.uk\/datasets\/soil-parent-material-model\/\">Soil Parent Material Map<\/a> and displayed via dictionaries of &#8216;excavatability classes&#8217;.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is excavatability?<\/h2>\n\n\n\n<p>Excavations are dug for a range of civil engineering purposes including cuttings, borrow pits and quarries. Typically excavations to 2\u20133 m&nbsp;are for foundations, utilities infrastructure, cellar construction, grading and burial pits.<\/p>\n\n\n\n<p>Excavatability is a measure of how easy it is to remove earth materials and is used to determine appropriate excavation methods. It is a function of the geotechnical properties of the material (strength or density) and mass characteristics, in particular mechanical discontinuities.<\/p>\n\n\n\n<p>The stronger the material, the more difficult it is to penetrate, break and consequently remove. However, mechanical weaknesses, in particular discontinuities, are exploited to aid excavation. A very strong rock may be readily excavatable if it has closely spaced discontinuities while a moderately strong rock with widely spaced discontinuities may require greater effort to excavate.<\/p>\n\n\n\n<p>Additional factors that may affect excavatability include the maximum depth of penetration, bulk density, bulking volume and susceptibility to running (flow).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Definition<\/h3>\n\n\n\n<p>The description and classification of excavatability depends on the type of deposit. In engineering geology, earth materials are split into two groups: soils and rocks.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Soil<\/h4>\n\n\n\n<p>Soil is an aggregate of mineral grains or organic material that can be separated by gentle means such as agitation in water. Soil behaviour is determined by the particulate nature (specifically the particle size, shape and mineralogy), water content and material density. The mass properties of a soil are largely influenced by its material characteristics. <\/p>\n\n\n\n<p>The principal soil types are clay, silt (fine soils), sand, gravel (coarse soils), cobble and boulder (very coarse soils). Whether the soil is classified principally as fine or coarse is dependent upon the behaviour of the material. Discontinuities affect the mass strength of some soils, primarily clay and silt.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Rock<\/h4>\n\n\n\n<p>Rock is an aggregation of minerals connected by strong and permanent forces. The behaviour of the rock material depends on the material characteristics. The behaviour of the rock mass depends on a combination of the material characteristics and the discontinuities including spacing, roughness, persistence, filling, orientation and the number of sets.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Classification<\/h3>\n\n\n\n<p>The categorisation of excavatability is based on strength data collated for geological formations as identified in the <a href=\"https:\/\/www.bgs.ac.uk\/technologies\/the-bgs-lexicon-of-named-rock-units\/\">BGS Lexicon of Named Rock Units <\/a>(LEX) and the <a href=\"https:\/\/www.bgs.ac.uk\/technologies\/bgs-rock-classification-scheme\/\">BGS Rock Classification Scheme<\/a> (RCS). The strength data is derived from the <a href=\"https:\/\/www.bgs.ac.uk\/datasets\/bgs-civils-strength\/\">BGS Civils: strength<\/a> dataset and from the British Standards Institute (1999) code of practice for site investigation (amended in 2003 and 2009). The classification has been further subdivided to account for regional\/lateral geological variation where sufficient data exists. The degree of weathering of the geological unit has also been incorporated where possible. <\/p>\n<\/div><\/div><\/div><\/section>\n\n\n\n\n\t\t\t\t\t<section   id=\"latest-content-9223-block_574286b6385e6ca075524ca6aa84b682\" class=\"grid-section  primary-background   \" >\n\t\t\t\t\t\t<div class=\"container\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"row header-of-section\">\n\t\t\t\t\t\t\t\t<div class=\"col-12\">\n\t\t\t\t\t\t\t\t\t<h2>You may also be interested in<\/h2>\n\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"row grid-wrap\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"col-lg-6 col-12\">\n\t<div class=\"cards cards-orizontal-sm  cards-find-more  cards-bordered\">\n\t\t\t\t<a href=\"https:\/\/www.bgs.ac.uk\/geological-data\/datasets\/\" class=\"media-wrap\">\n\t\t\t<img decoding=\"async\" src=\"https:\/\/www.bgs.ac.uk\/wp-content\/uploads\/2020\/01\/feature_250kSample-150x150.jpg\" class=\"lazy-blur wp-post-image\" alt=\"BGS Geology 250k sample\" data-src=\"https:\/\/www.bgs.ac.uk\/wp-content\/uploads\/2020\/01\/feature_250kSample.jpg\" \/>\t\t\t\t\t<\/a>\n\t\t\t\t<div class=\"info-wrap\">\n\t\t\t<div class=\"info\">\n\t\t\t\t<h4><a href=\"https:\/\/www.bgs.ac.uk\/geological-data\/datasets\/\">Datasets<\/a><\/h4>\n\t\t\t\t\t\t\t\t\t\t\t\t\t<p>We have a wide range of  licensed geoscience data.
