• 320 km girders have been cast.

• Construction of 14 river bridges has been completed across districts such as Valsad, Navsari, Kheda, and Surat, showcasing precision civil engineering over diverse terrain.

• Seven steel bridges and five prestressed concrete (PSC) bridges have also been completed.

Gujarat Surges Ahead

Gujarat continues to dominate the construction charts:

• Progress of around 143 km of track bed construction has been achieved so far in Gujarat.

• 3 lakh noise barriers have been installed over 150 km.

• Rail welding work for 200-meter-long track panels is in progress.

• Over 100 overhead equipment masts (OHE) have been installed between Surat and Bilimora bullet train stations.

Additionally, six of the eight stations in Gujarat have completed their structural work.

Maharashtra Catches Up With Tunnel, Station Work

In Maharashtra, focus has shifted to complex tunneling and underground station development:

• The 21 km tunnel between BKC and Shilphata has achieved 3.3 km of cumulative tunnel heading using the New Austrian Tunneling Method (NATM).

• Seven mountain tunnels are also being executed in Palghar district.

• Vikhroli and Sawli shafts have reached the required depths of 56 and 39 meters respectively.

At Mumbai Bullet Train Station, major excavation and foundation work is ongoing:

• 75 per cent of the total 18.7 lakh cubic meter earthwork is completed.

• 25,000 cu.m. concrete has already been poured for the base slab out of the planned 2 lakh cu.m., using temperature-controlled concrete from in-situ batching and chiller plants.

• Secant piling work (3384 piles) is fully completed.
