About this event

The ICE Specification for Piling and Embedded Retaining Walls (SPERWall) is the UK's pre-eminent technical specification for piling and embedded walling works. This 3rd 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.

In the first part of this evening meeting, Tony and Pete will describe the main changes made to the document since the 2nd edition, and the factors that drove these changes. The existence of an agreed way of executing piling works helps to reduce disputes on site and enables consultants to design more economically by having confidence in how the site works will be carried out. In the second part of the meeting, some common consultant and contractor pitfalls in writing and executing a piling specification from each other's perspective will be discussed.
