SWR gonna do Final Location Survey for Rail Network Expansion

In a big move to upgrade train system, South Western Railway (SWR) gonna do Final Location Survey (FLS) for various projects, like doubling and quadrupling of train tracks.

The big boss guy, Construction Officer, on behalf of The President of India, has invited E-Tenders for these important survey projects in the SWR/CN area.

*Stages of FLS Work*
Stage – 1: Initial study of Satellite Imagery, DEM, DSM, feature extraction, and development of topographic maps. Establishing control points and verifying obligatory points, followed by evaluation of horizontal and vertical alignment.

Stage – 2: Finalization of alignment using photogrammetric techniques, Drones, and LiDAR survey. Includes geotechnical and hydrological studies, approval from Railways, and preparation of topographical maps.

Stage – 3: Preparation of general arrangement/drawings for structures, Yard engineering scale plans, layout plans, and detailed estimates. Works commence after finalization/approval of L-section in stage 2.

SWR fir Simple a Location Survey karne wala hai Rail Network ki Expansion ke liye. South Western Railway (SWR) ne railway infrastructure ko enhance karne ke liye ek significant move li hai, jiske tahat railway lines ki doubling aur quadrupling jaisi various projects ke liye Final Location Survey (FLS) conduct ki jayegi. Chief Administrative Officer, Construction, Bharat ke President ke taraf se, SWR/CN region ke andar ye crucial survey projects ke liye E-Tenders invite kiye gaye hai.
