Tunnel engineering poses many challenges with respect to the design of tunnel support system. Many factors govern the safety of a tunnel. Also stringent analyses is necessary for analyzing the safe excavation procedures. Noble Geo-Structs Pvt Ltd provides services to meet these challenges. One of the challenging projects included tunneling below Arabian sea. Construction of shafts has also been a major part of the tunneling projects. Dr. Kulkarni has been providing recommendation since 30 years and more.
Landslides have proven to be hazardous resulting in to severe damage to industries, infrastructure and life; costing many millions!!! Hence landslide mitigation measures form a very crucial part. Noble Geo-Structs Pvt Ltd specializes by providing expert, innovative and cost-effective solutions to mitigate landslides. Protection measures for both natural and man-made slopes are recommended by NGS Pvt Ltd.
