Geotechnical risk and performance: with a focus on earthworks compaction and data management

Abstract

Abstract This paper discusses the various influences controlling risk and performance from new build to the in-service aspects of the transport infrastructure geotechnical asset of which earthworks are the major part. First it focuses on the risks associated with earthworks during construction. Compaction specifications, their origins and past supporting research results are described as are the advantages and disadvantages of the end-product. The method specification gives an insight into the development of earthworks design, construction and contracts. Recommendations are given based on modern practice and current contractual arrangements. Monitoring performance is critical to the management of geotechnical assets and the establishment of IT based methods in the UK is discussed to complete a ‘cradle to grave’ review of risk and performance aspects of earthworks.
