3.	The topographic shall be sufficient to provide all the data required for a detailed design for the project considering slopes required for storm drainage, roads, connections, intersections etc.

4.	While a minimum 80 to 100m long corridor for the topographic survey is acceptable as a general rule, however it cannot be limited, in case the slope variations in the near vicinity are significant or notably inter-dependent features like existing roads/ buildings/ walls/ bridges exist. Consider increasing the width of the corridor on both sides where necessary.

5.	A CSV file in PNEZD format shall be submitted on 5 non-writable CDs with the submittal.
