With the increase in water depths required in ports in the last 25 years, the design and construction of piles and walls for quay walls and jetties have become increasingly critical. Steel combi-pile walls are used extensively and the use of reinforced concrete diaphragm walls and cast in-situ piling is again becoming more common.
The third edition of the ICE Specification for Piling and Embedded Retaining Walls was published in 2012 and reflects some of the developments that have affected piling for structures in ports, harbours and other inshore marine locations.
The first part of this seminar will consider how the understanding of the design and construction of concrete cast in-situ piles and diaphragm walls for maritime works has developed and how this has been reflected in the Third Edition of the Specification.
The second part of this seminar will consider an innovative Scandinavian piling system, will then review steel piling practice for maritime works, with a particular emphasis on achieving compatibility between the indicated design, the specification and achievable installation tolerances and finally consider how the Specification addresses these issues.
The presenters have practical experience of both design and construction and most have been directly involved with preparation of the new edition of the Specification. The seminar will provide opportunities for contributions from the floor and for questions to the presenters.
The following materials are available for download:
David Puller – Geotechnical Experts Limited - "Guidance for good practice in bored pile and diaphragm wall design and construction for marine structures"
Lessons learnt from 30+ years of project experience designing and constructing cast-in-place piles and diaphragm walls.

The Third Edition of the ICE Specification for Piling and Embedded Retaining Walls (SPERWall) – What we've learnt; changes to European Guidance on Tremie Concrete; why SPERWall has been changed; what has been changed ; how that affects the design, specification and construction of piling for maritime works using concrete.
