Three months after the Rs 852-crore Bandra-Worli sealink opened to the public, it has developed leaks and there are cracks on the road surface, says a report submitted to the state government.

The leaks are dangerous as seepage will weaken the structure.

In its September progress report, Dubai-based Dar Consultants, the project designers and consultants, pointed out there are leaks on the 5.6-km sealink’s decks, the surface on which 25,000 vehicles ply every day, and that the bitumen - a tar-like substance used to smoothen the road surface - is cracking.

Water accumulates on the surface of the bridge because of condensation and rain, but it should not seep into the structure.

“Water leakage is a major cause for concern when it comes to the structural stability of any construction as it leads to corrosion. If it’s not addressed, it will cause structural instability,” architect Nitin Killawala said.

In bridges, seeping water can corrode the steel bars in the decks and the beams that support them. “There shouldn’t be any leakage in a structure like the sealink,” Killawala added.

The Maharashtra State Road Development Corporation, which funded the construction of India’s first sealink, said the consultants had informed them about the leakage. “Yes, the consultants pointed out the leaks. However, they are minor in nature and there is nothing serious about them. The bridge has been built as per international standards and it is stable,” MSRDC’s chief engineer Sharad Sabnis told HT.

Sabnis said the MSRDC would take up the issue with the contractor, Hindustan Construction Company.

“We are tackling routine issues whenever they are brought to our notice by Dar MSRDC. The bridge has been constructed according to international quality standards and as the records say, Dar Consultants has supervised and certified each and every activity of the bridge as per contract,” HCC chief engineer D.K. Sharma said.

Dar Consultants was unavailable for comment.
