Bids can be submitted at the NHSRCL office from 26th April to 22nd August this year, and the Technical Bid will be opened on 23rd August in the presence of representatives of the bidders.

A geo-technical investigation of the undersea tunnel area was conducted last year by a team of engineers from NHSRCL, RITES Ltd and Japan’s Kawasaki Geological Engineering. To determine the density of the rock under the sea bed, a survey was done by using static refraction technique (SRT) to study the sea bed. The final report was submitted last year.

Apex institutes like Zoological Survey of India (ZSI), Mangroves Survey of India (MSI), National Institute of Oceanography (NIO) have studied the environmental impact of the project area and have given environment clearance for the project claimed NHSRCL.

“ZSI in their report have stated that there is minimal disturbance to the wildlife in this region. No mangroves will be cut in this area as it will be an undersea/underground tunnel 20-40 meters below the ground/sea level,” said Sushma Gaur, NHSRCL spokesperson.

The NHSRCL spokesperson had also said that all related environmental clearances from authorities such as Coastal Regulation Management Authority, the National Board of Wildlife and the forest department have been received or principally agreed for approval.
The bullet train project is to be completed by August 2022 and the trains would be travelling at speeds greater than 300 km/hr. There would 12 stations between Mumbai and Ahmedabad. India would have to pay Rs.7000 crores for 18 bullet trains from Japan.
