Central Railway Tender

Conducting photogrammetric survey using stero satellite imagery data (CARTOS set or similar) as obtained from NRSC (national remote sensing centre) and processing the same using suitable GIS software for generation of Digital Elevation Model (DEM), orthophotos, topo maps etc.to verify the alignment by first identifying viable routes as per the requirement of Railway and finalization of most technical and economical alignment in consultation with Railways duly adopting latest circular/manuals/code of Railways with submission of detailed survey report along with abstract estimate as directed by the Engg-in- charge. The scope of the work includes suggesting viable routes for 130 kmph and 160 kmph as per terms of reference. The work shall be done as per 1 detailed specifications given in the tender document. 1)Submission of reports with definite recommendations. 2) Submission of records duly plotting the proposed alignment in topo sheets as well as in google earth. 3)All other deliverables as mentioned in tender document. Note: 1. The various deliverables in this item such as DEM, ORTHO PHOTOS, DSM, TOPOGRAPHICAL MAP to a scale of 1:5000 are purely for the purpose of finalization of alignment. However, the accurate DEM/ORTHO PHOTOS/TOPOGRAPHICAL MAP shall be generated using drone/ LiDAR Survey. (Preliminary alignment is to be worked out with different technical & economical viable alignment options, (2 alignments for 130 kmph and 3 for 160 kmph with further conditions specified in para 5.1 of Terms of Reference) keeping in view the terms of reference, clearly bringing out advantages/ disadvantages of each option) (For both UP & DN lines)
