The methods of construction survey of three dimensional coordinates, which is carried out in part of No.1 line of Shanghai subway for the central axial line of the circular tunnel, is systematically introduced as well as the computation of the coordinates. The emphasis is put upon the concrete plan which is designed according to the requirements of accuracy including the horizontal and level control orders, the observation requirements and the instruments used. The survey results are assessed in accuracy and compared with the designed values. It is concluded that the former plan of observation and design is feasible.
