Updating CIRIA Piling Guides

Updating CIRIA Piling Guides (P3198) – Good Practice Guidance

A CIRIA project is now underway to update CIRIA’s iconic piling guides. GCG are proud to be supporting this project as one of the sponsors. GCG’s Senior Partner Professor Kelvin Higgins is chairing the Project Steering Group, and Dr Apollonia Liana Gasparre, another of GCG’s Senior Partners, is also a member of the Steering Group.

CIRIA’s suite of piling guides were first published in the mid-70s and 80s and since then there has been tremendous advancement in the range of techniques, plant, equipment and materials used in the construction of piled foundations. There have also been changes to design standards, codes of practice and legislation during this time. These guides were very well received by industry at the time for their effectiveness in educating the reader on a whole range of piling related issues whether they were just starting their career or seasoned professionals.

The new CIRIA piling guides cover three key aspects associated with piling:

  • A review of bearing pile types (updating PG1 – 1988 2nd Edition). This will be complementary to the ICE Specification for Piling and Embedded Retaining Walls, third edition, 2017.
  • A review of problems associated with the construction of cast-in-place concrete piles (updating PG2 – Jan 1977). This will include piling techniques such as Continuous Flight Auger (CFA), sectional casing use and new materials e.g. polymer, which have been developed since the original publication.
  • A survey of problems associated with the installation of displacement piles (updating PG8 – Oct 1980). This will include bored displacement piles and screw piles.

The project aims are to:

  • Provide the piling industry with guidance to enable the training of site personnel, designers, construction managers and ground engineering specialists.
  • Help achieve better project outcomes for managing geotechnical risk.

GCG is looking forward to the launch and dissemination of these new CIRIA Piling Guides soon!
