| Principal Client | : | Rail Vikas Nigam Limited, India |
| Client | : | Eptisa India Ltd. Kolkata |
| Location | : | Railway Line Tunnel between Rishikesh and Karanprayag - Uttarakhand |
| Scope of Work | : | Detailed Design Consultancy Services for RVNL, 3 No. Adit Tunnels & Portals (A1 – 307m Long, A2 – 573m Long And A3 – 942m Long, total 1822m ) to facilitate the Railway Line Tunnel between Rishikesh and Karanprayag - Uttarakhand |
| Project Description | : |
Construction stage detailed engineering and numerical analysis related to adit tunnels & other associated works. The work will include review of available design reports & drawings, preparation of Basic design report, detailed engineering drawings & Design reports for Principal Client & Proof checker’s approval. The design shall be presented in such a way that the calculations are clear and easily understandable so as to allow the contractor or another design engineer in the construction stage to review, own and improve the designs during the implementation, if needed. All design & drawings should be fit for construction. Detailed work scope will include: 1. Review of available data & drawings provided by RVNL 2. Design inputs for preparation of Inception Report 3. Finalization of tunnel cross section 4. Adit tunnel portal excavation & support system design & drawings 5. Adit tunnel excavation & support system design & drawings 6. Tunnel lining design, numerical analysis & drawings 7. Main tunnel & adit tunnel junction design & drawings 8. Instrumentation 9. Any other supporting design & drawings in connection with the tunnel design. |
| Challenges | : | The geological conditions for Adit-3 was unfavorable for underground excavation in the Initial reach of about 150 - 200 m out of 942 m and materials consisting of mixture of sand, silty sand / sandy – silt (fine – coarse grained), and thin veneer of silty clay to clayey silt (clayey soil near the surface.), also accompanied by fractured, shattered rock mass material present to have heavy void ratio, which appears to highly permeable / more clayey layers and causing saturation & ground movements. In addition to above, the soil/rock mass in this reach of tunnel is under heavy tectonic stresses and seepage conditions and squeezing in nature. |
| Status | : | Design part has been completed Successfully within the stipulated time and construction is under progress |
| Consultancy in Preparation of Feasibility / DPR, Tender Stage and construction stage engineering design of Road and Highway Tunnels in the hilly terrain. |
| Our Team professionals are having individual experience in Roads and Highway tunnels for Designing of different level engineering. Some of the examples of road tunnel designing are given below: |
