The new ICE Specification for Piling and Embedded Retaining Walls
is designed to be used as the new technical specification for piling and embedded walling works either on land or near to shore. It documents the latest piling techniques and procurement methods used in the foundations sector whilst incorporating the changes introduced by the new European Standards.
Earlier editions of the specification have been very influential in raising piling standards in the UK and in other places where it is used. The existence of a standard agreed way of executing piling works helps to reduce conflict on site and enables consultants to design more economically by having confidence in how site works will be carried out.
The new document comprises three parts:
PART A: General requirements
- Part A – General Requirements
- Part B – Specification
- Part C – Guidance Notes
This part of the document contains the general guidance describing the requirements typically necessary for the successful construction of piling and embedded retaining walls. It includes information on the tendering process, design, and on issues such as safety, quality and the environment.PART B: Specification requirements for piling and embedded retaining walls
This part of the document is the main technical Specification advocated for use on piling and embedded walling works in the UK. It comprises 19 Sections covering the main piling and embedded walling methods, and the most common testing methods and materials used in these types of foundation works.PART C: Guidance notes on specification requirements for piling and embedded retaining walls
This part of the document provides specific guidance on the use of each of the 19 Sections within the Specification Part B. The guidance collates the experiences of contractors and consultants involved with piling and embedded retaining walls over many years.
This document has been designed for use with common practices, but is not intended to inhibit innovation. Novel solutions, such as the use of ribbed piles, piles with shaft enlargements or enlarged heads to piles, can be used with this specification provided that additional clauses are included in the project specification (containing the details described within each of the Sections in Part B) which will ensure that the final product is constructed in accordance with the design requirements. In addition, by referring to this document, Specifiers dont have to reproduce its standard clauses for every contract.
This is a major advance on earlier editions of the document. In addition to numerous updates and changes accounted for in this new edition, it also incorporates the essential commentary produced by the Federation of Piling Specialists (the essential guide from 1999) so, contained in one authoritative document are all the guidance documents needed to prepare and work to this piling and embedded walling specification.
Key changes since the 1996 edition
This edition incorporates the changes that have taken place between publication of the ICE Specification for Piling and Embedded Retaining Walls in 1996 and this new 2007 edition which includes:
- Two new methods now permitted for the concreting of CFA piles
- Procedures for CFA piling in restricted headroom
- Use of displacement auger piles
- New clauses for the construction and inspection of under-reamed piles
- Revised procedures for the testing of piles
- New clauses on the water-tightness of walls and how to measure it
- The concept of the Wall Manual
- Updated requirements for steel piling, sheet piles and welding.
