Core Objective Behind The Geotechnical Investigation;
This geotechnical study aims to gather essential data on the sub-soil conditions of the site. This information will assist contractors in developing an appropriate detailed design for the structures and selecting suitable machinery, methods, and technologies for construction.
Additionally, the study will help mitigate potential damage to existing structures during the construction process.
As per the terms and conditions of the tender, boreholes with a diameter of 150 mm will be drilled at regular intervals of 500 meters along the twin tunnel alignment. Additionally, 3 boreholes will be drilled at each station site. According to the basic consultant plan, the depth of these boreholes will range from 10 meters to over 20 meters.
Tender’s Description;

Please change a bpt hospital metro station and move the metro line by going through into wadala railway station. Why I’m telling this, because, in wadala railway station, we get the both option either monorail(to go saat rashta monorail stn) and in harbour line(Goregaon/Panvel). We can easily switch in between if this happens. I’m requesting you please make a change, which I have mentioned.
