Chenani-Nashri tunnel completes 2 kms excavation
The Chenani-Nashri tunnel project, which is being developed by Leighton Welspun, has completed excavation of 2 km combined length of the two Escape Tunnels, North and South. This time keeps them well on target to complete the tunnel to their planned schedule.
On the North Escape Tunnel 829 metres of excavation and on the South Escape Tunnel 1,174 metres have been completed. In April alone, the project team excavated 180 metres in the North and 201 metres in the South giving an average of 6.0 and 6.7 metres per day respectively.
The main tunnel has also progressed well, despite its larger size. The combined length of the two headings has almost reached 1.4 km with 656 metres excavated in the North and 733 meters in the South. The North advanced 123 metres in April and the South 147 metres, giving advance rates of 4.1 and 4.9 metres per day respectively. The project is well on track to be completed on-time and within budget.
