- Tender Ref No.: NHSRCL/CO/CA/SIA/2020/36
- Name of work: Conducting Survey / Field Work & Preparation of Detailed Social Impact Assessment (SIA) / Resettlement Action Plan (RAP) for Mumbai-Hyderabad High Speed Rail Corridor (About 711 Kms Long).
In November last year, the NHSRCL had invited online tender for the Tender Ref No.: NHSRCL/CO/CA/SIA/2020/36.
Upcoming High Speed Rail corridors in Indian Railways:
Currently, the NHSRCL is constructing the Mumbai-Ahmedabad High Speed Rail corridor. Also, Railways has assigned the work for the preparation of Detailed Project Report (DPR) for the following seven new High Speed Rail (HSR) corridors to National High Speed Rail Corporation Limited (NHSRCL):
None of the above seven High Speed corridor is sanctioned as yet. The decision on sanctioning any HSR project depends on the outcome of Detailed Project Report, techno-economic feasibility, availability of resources and financing options. The preparation of DPRs is still in progress and alignment/route for the corridors has yet not been finalised.
The NHSRCL has already started the LiDAR survey for preparation of Detailed Project Reports (DPRs) for Mumbai-Nagpur High Speed Rail Corridor (approx. 736 km) and Delhi-Varanasi High Speed Rail Corridor.
- The proposed plan for Mumbai Nagpur HSR Corridor (approx 736 km) will connect Mumbai city with cities/towns like Nagpur, Khapri Deport, Wardha, Pulgoan, KaranjaLad, Malegaon Jahangir , Mehkar, Jalna, Aurangabad, Shirdi, Nashik, Igatpuri, Shahapur.
- The proposed plan for Delhi-Varanasi High Speed Rail Corridor will connect the National Capital Territory (NCT) of Delhi with major cities like Mathura, Agra, Etawah, Lucknow, Raebareli, Prayagraj, Bhadohi, Varanasi and Ayodhya.
- The main corridor from Delhi to Varanasi (Approx. 800 km) will also be connected to Ayodhya.
- The High Speed Rail (HSR) route will also connect the upcoming international airport at Jewar in Gautam Buddha Nagar District of Uttar Pradesh.
What is LiDAR technology?
NHSRCL is adopting Light Detection and Ranging Survey (LiDAR) technology which provides all the ground details and data in 3-4 months wherein this process normally takes 10-12 months.
- The ground survey is a crucial activity for any linear infrastructure project as the survey provides accurate details of areas around the alignment.
- This technique uses a combination of Laser data, GPS data, flight parameters and actual photographs to give accurate survey data.
- During the Aerial LiDAR survey, 150 mtrs of area around the proposed alignment is being captured for the survey purpose.
- After the collection of data, Three Dimensional (3D) Topographical map of corridor of the proposed alignment on a scale of 1:2500 will be available for designing of the vertical & horizontal alignment, structures, location of the stations and depots, Land requirement for the corridor, identification of project affected plots/structures, Right of Way etc
- To provide clear pictures of the structures, trees and other minute ground details,100 megapixel cameras are being used for the LiDAR survey.
- NHSRCL has been entrusted to prepare the Detailed Project Reports for seven (7) High Speed Rail Corridors and LiDAR survey technique will be used for ground survey in all the corridors.
