ABSTRACT

Despite a present, short-term economic recession a remarkable enthusiasm exists in Hong Kong for building infrastructure including major tunnel projects.

This paper provides details of current and recent bored tunnel works together with an insight into the impressive list of future underground projects planned by the MTRC, KCRC, Highways Department and Drainage Services Department for the next decade. Risks for each of these works and pipejacking, mixed face and rock tunnelling generally in Hong Kong are also identified.

From this is evident that the scale and difficulty of such works continues to increase, requiring the use of more sophisticated methods of construction, the need for better methods of assessing and managing risks and for Government to utilize improved, more equitable Conditions of Contract for such major tunnelling projects.
