Design by auditing firm D.D. Desai scrapped; BMC to invite bids, award work after new consultant submits designs

The Brihanmumbai Municipal Corporation's (BMC) work on building approaches to Delisle Bridge has not yet taken off though the Western Railway (WR) has finalised a contractor for the reconstruction of the bridge.

The approaches were initially designed by auditor D.D Desai’s firm but following the Himalaya Bridge collapse, the BMC asked a different firm to vet the designs.

After the collapse of the bridge in March, in which seven people lost their lives, the BMC’s primary report had largely pinned the blame on structural auditor Prof. DD Desai Associated Engineering Consultants and Analysts Pvt. Ltd. The police arrested the firm’s director Neeraj Desai and the BMC took away work from the firm. In the case of bridges allotted to the firm for structural audit, the BMC is in finalising a contractor for a re-audit.

One such work was of designing the approaches to the Delisle Road overbridge. “We have given the work to another consultant from our panel. The designs are expected soon. We will then invite bids and award work. Our work is not as complicated as that of the railway. It will go on simultaneously,” said Additional Municipal Commissioner Vijay Singhal. Officers said the work may cost around ₹70-₹100 crore.

WR has finalised and awarded the contract for the new Delisle Bridge, which will take 10 months to complete. The bridge will be built in place of the century-old bridge that was dismantled earlier this year.

The contract for the new bridge has been awarded to the joint venture firm, Saidutt-Dynamic-Sobti, and will be built at a cost of ₹86.52 crore. The work is being executed by WR, but the BMC will bear the cost.

The new rail overbridge (ROB) will have a six-lane road with pedestrian pathways on either side. The ROB will be 85 metres long and span five tracks. It will have a provision for the proposed sixth line between Mumbai Central and Bandra.

The main girders will be fabricated using high-grade steel. Similar to the old bridge, the new bridge will be built at a 64-degree angle. However, it will not have any pillars between the tracks and will rest on two main pillars on either end. As a result, it will be higher than the earlier bridge.

The BMC recently demolished 170 structures that were coming in the way of the Delisle Bridge demolition.
