Foreword Welcome to thislatest edition ofthe Institution ofCivil Engineers Specification for
PilingandEmbedded Retaining Walls, the thirdin a highlysuccessful series. Itcomes
somenineyears after the second edition and28yearsafter theoriginal ICE
Specificationfor Piling.
Theauthors wouldlikethis specification to continue to beinstrumentalin raising
standards forpiling and embeddedretaining walls andexhortuserstodevelopfuture
revisionsto keepthe standardcurrent, relevant andprogressive.
ThegreatmajorityofUK piling and embeddedwallcontractsuse thisspecification,
makingspecific project specification changes whereappropriate.This specification is
nowadopted byNetwork Rail, Highways Englandandis well known andrespected by
consultantsandcontractors alike.
Thethird edition of the specificationhasbeen producedbya numberof expert working
groups withwide consultation andcross-industrysupport.Theworkinggroups were
drawn fromconsultants, specialistgeotechnical contractorsand employerorganisations.
Therevisionsthathavebeenintroducedreflectthe manydevelopmentsin piling and
retaining wallsand
g enshrine best practice in the industryand update someof the testing techniquesthat
haveevolvedin recentyears
g reflectthe development of the relevant Eurocodes andsobringthe documentupto
date
g ensuretolerances arebetter understoodfor the varioustechniques
g providebetter guidance onconcrete specification and testing.
Changeshavebeennecessary to allthe sections soevenexperienced readerswill need to
study thefull documentandnotjustsectionsthatarenew tothis edition, which include
g a section on micropiling
g a section on helical (orscrew)piling
g updates on‘new’techniques suchas cased CFA piling
g guidance on theuse ofpolymer fluidsforexcavation support.
Thisedition retainsthe three-part approachof the second edition. PartA isan
introduction to the essentialconcepts necessary to procurea pilingorretaining wall
contract.Part Bisthe specification andisstill the onlypart ofthis documentintended
forincorporation in contracts.Part Cprovides guidance for useofthe specification and
essentialbackgroundinformationfor specifiers andcontractors alike. Unlikethe second
edition, Part3 guidance notesimmediately followthe relevant Part2 specification
requirements. Thethreesections providethe readerwithafullcompendium without
beingoverly prescriptive.
Inmy capacityas Chairman of theBritish Geotechnical Association, Ioffer mysincere
thanksto themany individuals whohavecontributedsomuch time,effort and
expertise tothe development of the specification, boththis edition andearliereditions
fromwhich ithasbeen developed, for the benefitof the very manyfutureusers.
Professor Stephan Jefferis
Chairman,British Geotechnical Association
