About Project

This survey work carried out in three different phases. In the first phase all T.B.M. points were fixed at every 100m c/c with help of Autolevel machine with accuracy of ± 1.6mm per Km. In second phase accurate google coordinates at the same T.B.M. pillars were taken with help of DGPS satellite survey instrument. Triangulation Traverse method used with 4 to 6 hours of data collection of each T.B.M. in Static data recording. In Final phase, all points were rechecked with latest Robotics Total Station Machine and 360 prism with accuracy of ± 1 mm to each pillar. Total 40 Km Stretch data provided in metro project.
