RTK Survey TBM Available : The Contractor must obtain the existing Static GCP points from CMWSSB which should be considered as the control point with known coordinates X, Y and Z. Survey consultant to ensure the closing error is within permissible limits (SoI Standards) while transferring the levels from the existing Static GCP points and the same to be presented as a report. The same process shall be adopted for random verification of positional accuracy of points established using the PBMs as base. As built survey for every sewage and water pipeline and other assets must be done using DGPS based RTK method by transferring the coordinates from the nearest Static GCP of CMWSSB. Where there are signal interruptions for the RTK method, Total Station can be used. The coordinates from the static GCP shall be transferred to the Total Station by RTK method and the co- ordinates of the assets can then be captured by Total Station. All the features, attributes of all the assets, utilities captured shall be Geo referenced as per standard Coordinate reference system (WGS 84 UTM Zone 44N).
