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. The static GCP must be established from this PBM using triangulation network method and Frog & leap method for linear areas. The contractor must strictly avoid radial offset method. If the PBM is not available with CMWSSB within the area of interest, the contractor must procure the nearby Survey Of India, GTS benchmark available to establish the static GCP of the project location using the above mentioned methods only.

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). The final base map with assets and utilities shall be furnished in (.shp) format. The geo referenced assets and utilities along with the attributes (as specified by the GIS Wing, CMWSSB) shall be converted into proper geo database (FGDB / PGDB) with the attributes. One set Hard and Soft Copy of all the CMWSSB 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.
