The ICE Specification for Piling and Embedded Retaining Walls (SPERWall) is the UKs pre-eminent technical specification for piling and embedded walling works, either on land or near to shore. This edition has been updated to reflect the latest piling techniques and procurement methods used in the geotechnical sector, as well as revisions to the Eurocodes, British Standards and CIRIA guides.This volume:includes new sections on micropiling and helical piling as well as guidance on the use of polymer fluids for excavation supportensures tolerances are better understood for the various techniquesprovides further guidance on concrete specification and testingThis edition retains the three-part approach of the second edition. Part A is an introduction to the essential concepts necessary to procure a piling or retaining wall contract. Part B is the specification and is still the only part of this document intended for incorporation in contracts. Part C provides guidance for use of the specification and essential background information for specifiers and contractors alike.This specification has been one of the most popular of ICEs standard specifications and has been fundamental in raising piling standards in the UK, as well as where it has been applied around the world.
