An outline of the survey work necessary for the construction of a large tunnel project such as the San Francisco Bay Area Rapid Transit System is presented. In the second part of the paper, a method for shield or tunneling machine control by laser and double target is described. This method has proven successful during the driving of the tunnels of the BART system both by hand and machine methods.
