It is proposed that the 3dcoordinate method should be used as the solution to the problems caused by narrower construction sites where the traditional methods are not applicable. By using total station to survey the angle, distance and elevation at the same time, the differences of coordinate of observation points can be measured, and the horizontal displacements and differential settlement can be attained. This flexible, convenient, economical and efficient method can be used instead of direct leveling when other methods are unsuitable, especially in the narrower field. According to the analysis of the precision and the comparision of the data of settlement measurement, the precision of this method meets the requirement of the observation of deformation.
