conducting technical specifications covering detail survey including route alignment, profiling, tower spotting, contouring and soil investigation. The scope of work inter-alia shall include the route alignment using satellite imageries of NRSA, Google images and Survey of India maps, inter-alia including 1. Identification of three alternative route alignments & selection of optimized route alignment in consultation with the owner. This shall be done using low resolution satellite imageries of NRSA, Google images and Survey of India maps. The output shall be in the form of digitized route alignment drawing with latest topographical and other details/features up to 2 Kms. on either sides of selected route alignment (both in hard and soft copies). 2. Digital terrain modeling along the selected route using contour data from topographical maps. Associated field work. 3. Detail Survey using GPS, DGPS, Total Stations, long range scanners & Digital theodolites of reasonable accuracies or alternatively using ALTM, (Airborne Laser Terrain Modeling) techniques, inter-alia including i. Digitized profiling along the selected route along with plan details using Power Line Systems Computer Aided Design and Drafting (PLS- CADD). ii. Computer aided tower spotting & optimization. iii. Soil resistivity measurement along the route. a) Digitized contouring at undulated/hilly tower locations.
