Correct evaluation of cut and fill volume of soil is one of the most important factors which controls construction cost in enormous construction sites. To achieve accurate computation of soil volume in construction site precise surveying is required, however most of construction sites adopt existing optical surveying instruments such as Total Station. The problem when using these optical instruments in construction sites is that these instruments take longer time in data acquisition. Due to insufficiency of computation time accurate and precise observation cannot be accomplished with these equipments. As a result roughly calculated earthwork volume may cause arguments between contractors and supervisors in the matter of reduction or increasement of total construction cost. In this study VRS-RTK Surveying is adopted to perform fast and accurate in-situ surveying for rapid computation of soil volume. This VRS-RTK Surveying system is proved to have more accurate three dimensional coordinates with high density and better economical solution with less manpower.
