The Gujarat Metro Rail Corporation (GMRC) has taken another significant step towards expanding Ahmedabad’s metro network by inviting bids for the geotechnical investigation of the proposed Ahmedabad Metro Phase 3B corridor. The tender marks the beginning of on-ground preparatory work before construction of the new metro stretch can commence.
The proposed Phase 3B corridor will cover a 12.576-kilometre elevated route from Canal Road to Badrabad Dead End, strengthening connectivity across the rapidly developing western parts of Ahmedabad.
Geotechnical Survey to Be Completed Within Four Months
According to the tender released by GMRC, the selected agency will carry out detailed geotechnical investigations for the entire elevated viaduct.
Key Tender Details
- Project: Ahmedabad Metro Phase 3B
- Corridor Length: 12.576 km
- Route: Canal Road to Badrabad Dead End
- Estimated Cost: ₹1.46 crore
- Completion Period: 4 months
- Bid Submission Deadline: July 23, 2026
The investigation will assess soil conditions, foundation requirements, and engineering feasibility before civil construction begins.
What Is a Geotechnical Investigation?
A geotechnical investigation is one of the most important stages before any metro project enters the construction phase.
The study includes:
- Soil drilling and sampling
- Ground strength analysis
- Foundation recommendations
- Underground water assessment
- Structural suitability for elevated viaducts and stations
The findings help engineers design safe and durable metro infrastructure while reducing future construction risks.
Ahmedabad Metro Expansion Continues
GMRC has been actively moving forward with multiple expansion projects across Ahmedabad. Earlier this month, tenders were also issued for the Phase 3C Ring Corridor, while consultancy and survey works for Phase 3A and Phase 2 extensions are already progressing.
These developments indicate that Ahmedabad’s next phase of metro expansion is steadily moving from the planning stage toward execution.
Metro Network Expected to Improve Urban Connectivity
Once completed, Ahmedabad Metro Phase 3B is expected to improve public transportation by:
- Reducing travel time across western Ahmedabad
- Enhancing connectivity with existing metro corridors
- Supporting residential and commercial development
- Reducing traffic congestion and vehicle emissions
The new corridor forms part of GMRC’s long-term strategy to create a larger, integrated metro network for Ahmedabad and Gandhinagar.
Conclusion
The launch of the geotechnical investigation tender represents another important milestone for Ahmedabad Metro Phase 3B. While construction is yet to begin, the survey work lays the technical foundation for one of the city’s upcoming metro expansion projects. With multiple metro corridors currently under planning and development, Ahmedabad continues to strengthen its position as one of India’s fastest-growing urban transit networks.
