This paper presents and discusses the findings of a questionnaire on the current and future use of remote control tunnelling machines (RCTM) in the UK tunnelling market. The questionnaire was prepared by the Project Management Group of the University of Manchester Institute of Science and Technology (UMIST), and sent to 105 UK organisations which undertake tunnelling as part of their business activities. The survey's findings illustrate companies' views about the financial, technical, market, environmental, and legislative constraints on this market. For almost a decade, the UK market has accepted microtunnelling as a technique for constructing tunnels up to 900mm diameter, but still uses traditional construction techniques for tunnels with 900mm to 1800mm diameter, despite their disadvantages and dangers. Trenchless techniques have considerable social and environmental benefits, including reduced noise, congestion, and traffic disruption. The main criterion for choice of construction technique remains the lowest cost to meet the required technical specification, and RCTM usually have higher capital costs. Several respondents considered RCTM techniques acceptable for a variety of tunnel construction projects. The best ways to increase the market for RCTM would be more legislation and public pressure for their use.
