IntroductionIn underground engineering such as construction of a railway tunnel or a flood-charge tunnel.it is very important to measure profiles for saving construction cost and checking construction quality Conventional methods of profile measurement in tunnelling are labor intensive both in taking the measurement and in their evaluation.Now a laser instrument product for automatic profile measuring has been developed and produced by AMBERG MEASURING TECHNIQUE Ltd in Switzerland Currently.the joint production of this type of equipment is discussed between DANDI.AMBERG MEASURING TECHNIQUG Ltd.and GAITE Corporation
