Bench Mark, including additional cross sections (both U/S & D/S) at the points of bridges, regulators, cross drain, inlets, tributaries, branch channels, drains, out channels from pump houses, important structures etc., including additional cross sections at adjacent outfall point of these Drainage Channels/Khals/Rivers into other river for 250 mtr U/S & 250m D/S of that outfall point and showing detailed topography plan of all permanent & temporarily features like roads, canal, bridges, park culvert, boundary wall, Electric post, transformer etc. as available within the area, also including preparation of survey plan showing the location of topo point of FRL/G.L/Bed level/Berm level/HFL/LWL/Free-board/Pond/depressions/road etc. with appropriate R.I. and open area/green area/total ground coverage/nature of land for mentioning in the drawing with suitable scal,true north &relavent photographs etc. as per direction & satisfaction of E.I.C. complete in all respect. The cross section interval shall be fixed as & when required as per direction of E.I.C. Raw data for mathematical modelling ( in specified format as per direction of concerned authority) of survey work will also be submitted in time to time during working day. ii)Cross-Section width 250.0m to 1000.0m and cross-section interval of 30m to 120m c/c along river/khal/drainage channel etc Kangsabati & Kumari River a) upto 5.00km
