Description:This standard gives recommendations and guidance for unreinforced
earthworks forming part of general civil engineering construction,
with the exception of dams. This standard also gives recommendations
and guidance for temporary excavations such as trenches and pits.
NOTE Reinforced earthworks are covered in BS 8006-1 and BS 8006-2.
This document applies to earthworks classified as Geotechnical
Category 1, 2 and 3 structures as defined in BS EN 1997-1-2004.
Overview: BS 6031:2009 Code of practice for earthworksBS 6031 - Best practice guidance on geotechnical aspects of earthworks and on working practices What are earthworks?Earthworks are:1) Structures formed by the excavating, raising or sloping of ground, e.g. embankments, cuttings or remediated natural slopes2) Civil engineering process that includes extraction, loading, transport, transformation/improvement, placement and compaction of natural materials (soils, rocks), and/or secondary or recycled materials, in order to obtain stable and durable cuttings, embankments or engineered fillsEarthworks are commonly associated with transport infrastructure, but there are many other important applications:Platforms for industrial, commercial and residential buildingsWater engineering, flood defence and coastal protection worksOther civil engineering projects.What is included in BS 6031?BS 6031 gives recommendations and guidance for unreinforced earthworks forming part of general civil engineering construction, with the exception of dams. It also gives recommendations and guidance for temporary excavations such as trenches and pits.BS 6031 reflects the actual processes that might be followed on a typical project to deliver the earthworks. In practice earthworks design is an iterative process where the employer, consultant, main contractor, sub-contractors and construction validation team often take design decisions. To reflect this situation BS 6031includes some subjects in more than one clause.What has changed from the previous edition of BS 6031?This revision of BS 6031 reflects the widespread UK practice of using the Specification for Highway Works (SHW) 600 series for the construction of earthworks. Within this standard, the SHW has been set as the default approach for earthworks specification that applies unless the designer details an alternative form of specification/earthworks management system. This edition of BS 6031 is set out in clauses to reflect the overall earthworks process: where earthworks are planned, designed, constructed, adopted/approved following construction, and then the earthworks moves into an asset management process. This cycle is only broken when the earthworks reach the end of their useful life and are decommissioned. BS 6031 recognizes that construction of new earthworks and the remediation or repair of existing earthworks are activities that have similarities and significant differences. Wherever possible, clauses cover both construction and remediation activities, which need to be taken into consideration as appropriate.This version of BS 6031 replaces the 1981 version, which is now obsolescent.What is the relationship between BS 6031 and BS EN 1997-1 (Eurocode 7, part 1)?This version of BS 6031 brings it into line with BS EN 1997-1:2004. The style adopted within BS 6031is to cross-reference BS EN 1997-1:2004 (not repeat it). BS 6031 is non-conflicting complementary information (NCCI) to BS EN 1997-1.Who should use BS 6031?Civil engineersConstruction workersConsultantsContractorsContents of BS 6031:ForewordSection 1: GeneralIntroductionScopeNormative referencesTerms and definitionsThe control of riskSection 2: Design and management of earthworksPlanning of earthworksSite conditions and investigationsDesign of earthworksSpecification of earthworks fill materialsConstruction of earthworksAdoptionEarthworks asset managementDecommissioning and disposal of earthworks assetsSection 3: Temporary excavations, trenches, pits and shaftsTemporary excavationsConstruction procedureTrenchesPits and shaftsAnnex A (informative) Potential modes of failure of slopesBibliographyList of figuresList of tablesSee more information on Eurocodes
