A concrete girder or `section’ of an under-construction metro bridge developed a crack soon after it was launched on pillars here on Tuesday, officials said.
While traffic was diverted as a precautionary measure, the “deformed” concrete segment, part of a span having nearly a dozen such box girders, will be replaced, they said.
The span between pillars 747 and 748 is part of the east-west corridor of the metro project connecting Saroli with Kapodra, said a release by the Gujarat Metro Rail Corporation Ltd (GMRC).
“The final stressing of the box girder span was completed at 1:30 am and it was kept under observation for 24 hours as per rules. At around 2:00 pm, one segment deformation was noticed. The deformation of the bridge is being continuously monitored and is in stable condition,” said the statement.
Since the load of the bridge is still on launching girder, the damaged structure can be removed by following standard procedure, the company said.
“The cause of the deformation can be ascertained only after the removal of the segment,” it added.
GMRC general manager (civil) Yogendra Singh Chauhan said there was no need to panic.
“There are thousands of segments in such bridges and it is normal to have such minor issues in one of them. We will destress the cables (which keep together all span segments) and change that segment,” he said.
