Tunnelling Contracts and Site Investigation

Tunnelling is a high risk business. Success depends crucially on the nature of the ground through which the tunnel is being driven. The cost of a thorough site investigation is usually only a small fraction of the cost of the construction work but this crucial phase of a project is often given too low a priority. Tunnelling Contracts and Site Investigation provides a practical and wide-ranging review of tunnelling contracts, particularly those for sewerage and drainage tunnels. It reviews site investigation methods, contract preparation and tender evaluation, tunnel costruction, claims and records, and the post-construction phase. Examples of good and bad practice of site investigation and other aspects of tunnelling are given, and the text is supported by over 500 references. Supplementary information in the second part of the book expands on particular aspects such as ground vibration and noise in considerable detail. Among other topics covered are quality assurance, rock properties and testing, pollution, permeability and dewatering. The book is aimed particularly at practising engineers involved in the procurement and management of site investigation and tunnelling contracts. It will also be valuable for specialists in construction contracts, and for students, researchers and lecturers who need to keep up to date with new developments in tunnelling.
