The existing tunnel survey method contains many problems of taking much measuring time, increasing construction expenses, and delaying a term of construction, Therefore the site survey system for an improvement efficiency is developed. This system will be able to solve the error factor and the problem of curtailment of time and expenditure. In order to solve these problems it connected a measurement equipment and a notebook computer, and developed the system which simultaneously with tunnel measurement it will be able to decide locations and errors from site at real-time. The development of the tunnel survey system minimize the error occurrence as measuring tunnel, and the probability of more or less excavation. Therefore this site survey system leads to the effect of the improvement execution quality of work, the cost reduction and the construction term reduction.
