The Delhi Metro Rail Corporation (DMRC) on Tuesday awarded Paras Railtech with a Rs. 43.92 crore contract for constructing a 289.65 meter cut and cover tunnel (Package CC-126A) on the 1.218 km Najafgarh – Dhansa Bus Stand extension of Delhi Metro’s Grey Line.
This underground tunnel of the Phase 3 project’s Package CC-126 was originally awarded to Shanghai Tunnel Engineering Co. Ltd. – SUCG Infrastructure India Pvt Ltd (STEC – SUCG IN JV) in October 2017, and tunneling breakthroughs were recorded by the team using one tunnel boring machine (TBM) on January 18 and June 26, 2019.
As shared earlier – my industry sources indicate that a construction site collapse had occurred in July on a 90 meter wide cut and cover portion due to heavy rainfall and ingress of water at the extreme western end of the line, and due to that the DMRC removed a 289.65 meter portion of the up-line tunnel’s construction from STEC – SUCG IN JV’s scope of works.
DMRC invited bids for this tunnel’s pending work on September 21 with an estimate of Rs 48.99 crore and opened technical bids on October 13 to reveal two bidders – Paras . Financial bids were opened on October 24.
