The DMRC’s current estimate for the DC-09 is unknown, so I can’t gauge how Afcons bidding goes and what the next steps look like.
If it is within the acceptable limits of DMRC, we should be awarded a contract in the second quarter of 2022 with construction work early next year. When awarded, AFCONs will be required to use at least 5 Tunnel Boring Machines (TBMs).
