Hydro & Underground
We are constructing nine adjacent tunnels aggregating about 10 Km in Jammu region for KRCL. We have also been entrusted with another Tunnel Project valuing USD 325 Mn. from the Border Roads Organisation (In JV with Strabag of Austria). AFCONS entered into the field of tunnelling in the late eighties when it carried out tunnelling work for Calcutta Metro Railway, wherein a special blade shield technique was used for the construction of tunnel in soft soil. The complete blade shield was designed and fabricated indigenously by AFCONS. Tunnel construction in collapsible material is a specialised construction and AFCONS was the first company in India to have successfully executed such civil work by using Jet Grouting. AFCONS also executed another major tunnel project for South Eastern Railway at Lilligumma, when a contractor failed to overcome hazards due to collapsible soil and the work was awarded to AFCONS. AFCONS has completed total Tunnel length of 3946 m & tunnel work for 10223 m is in progress.
Our portfolio in the Hydro Sector consists of De-silting Arrangement at Koldam Hydro-Electric Project for NTPC.
