Preliminary survey for Identification of 3 alternative routes using satelite imageries (1:25,000 PAN +LISS merged) for NRSA.Google images and Survey of India maps and finalization of most economical, Optimum route showing the topographical and other features upto 8Kms on either side and indicating final selected route alignment and digital modelling final selected route alignment and digital modelling in undulated hilly terrain along the proposed route using contour data from topographical map and submission of preliminary survey reports for approval as detailed in technical specifications.

Detailed survey along the approved route alignment approval after conducting the preliminary survey by using Modern survey equipment like GPS/DGPS, Total stations including profiling tower spotting and optimization of locations by using computer aided technique like ALTM as well as other activities as detailed in the scope of work using PLS-CADD software and submission of draft report for approval. a. Drawing the route profile including Geographical features like Nalas, Rivers, Gardens, P&T Lines, Railways crossing etc. b. KMZ/KML file of approval route. c. Levelling of the profile with reference to Survey of India bench marks(MSL) d. Tower Schedule. e. Line Schedule. f. Burgle details by using Modern Survey techniques and providing GPS, Co-ordinates at each anchor points for identification of anchor locations indluding permanents marks like poles, telephones lines, buildings etc.

Providing and fixing RCC pillar (M-20) of size 150 X 150 X 1000 mm, with approved marks including painting above the ground level and yellow lettering and marking the direction of incoming and outgoing lines are to be marked clearly on the top with red colour.IF the distance between such anchors points is more than 1KM one more directional stone is to be fixed. So alos, for the road crossings, railway crossing and nala crossings on both the sides.

Conducting Soil resistivity test along the selected route and submitting the test results in the form of draft report as detailed in the technical specifications.
