A JV of Indian contractors Patel Engineering and SEW Infrastructure is to build a 12km long bored tunnel as part of a turnkey package of works for part of the Bargi Diversion Project in the state of Madhya Pradesh.
The 10m diameter tunnel is to be excavated by TBM, and Patel said it planned to use the shields to complete the key part of the major water project project ahead of schedule.
Details on the excavation programme for the project were not immediately available.
However, the JV expects to complete the package of works within 36 months. The client’s pre-tender estimation of the construction period was 48 months.
The underground works on the Bargi Right Bank Canal (Sleemanabad Carrier Canal) section of the water resources project will also include approximately 900m, in total, of cut and cover reinforced concrete transition structures.
The Narmada Valley Development Authority (NVDA) awarded the JV an engineering, procurement and construction (EPC) contract worth US$162M to build the tunnels as well as approximately 13km of canals.
Patel’s JV partner, SEW Infrastructure, was formerly SEW Constructions.
