THE BRITISH Tunnelling Society has published the new edition of its Specification for tunnelling.
An updated version of the 1997 Model specification for tunnelling, it reflects the 'significant changes in tunnelling techniques', said the BTS.
It is designed to be used as a contrac t specificat ion on its own or with other specifications on multi-disciplinary projects.
Published with the approval of the ICE Ground Board (now part of the British Geotechnical Association), the revision also took on board comments and suggestions from industry.
The original document was the first produced with the specific aim of establishing a common standard for design and construction of tunnelling in the UK. It now forms the basis of specification for tunnelling projects in the UK and worldwide.
