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 and establishing TBMs for the project area as instructed by CMWSSB Engineer. 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. While surveying by RTK method, it shall be ensured that the values are captured by “fixed” status. The DGPS RTK survey report including “fixed” or “float” for the coordinates captured and horizontal & vertical precision with raw data in OEM nativity file format like (.mdb, .jxl, .tet, etc) shall be submitted. 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).

The final base map with assets and utilities shall be furnished in (.shp) format. The geo referenced assets and utilities along with the attributes shall be converted into proper geo database (FGDB / PGDB) with the attributes. One set Hard and Soft Copy of all the assets and utility has to be prepared category wise network wise in A0 Print for verification in a print scale of 1:1000 in A0 plot, with standard legends in international and NUIS standards and should be legible and three sets of final Hard Copy in A0 print. For the Underground / Surface Assets along the roads for the distance above 100 km
