The CM also said that he would form a team to probe the cause for the honeycomb formation.

Passengers travelling via the purple line of Bengaluru Metro Rail on Wednesday morning were inconvenienced due to a sudden and unannounced delay in trains. This after metro officials noticed a honeycomb formation in the concrete of pillar number 155.

Speaking to the media on Wednesday evening, Chief Minister HD Kumaraswamy said that he had learnt of the formation of the cracks three days ago.

“During regular inspection, the engineers had found that cracks were formed on the pillar. I had learnt of this three days ago and had instructed the metro officials to rectify the situation as soon as possible,” Chief Minister Kumaraswamy said.

Honeycombs form in concrete due to imbalances in the materials used during construction, poor cement to water ratio, when the steel or iron bars are not placed properly after the concrete is poured, improper placement of reinforcement bars in the horizontal and vertical beams of the pillars or use of substandard materials.

When questioned about the cause for the formation of the honeycomb, Chief Minister Kumaraswamy said that he would launch an inquiry into it.

“I will consult with experts and form a team to probe the reason why the honeycomb appeared in the concrete. This will be fixed as soon as possible,” Kumaraswamy added.

The trains were plying at 15-minute intervals, causing delays for office-going commuters early on Wednesday morning.

The Bengaluru Metro Rail Corporation Limited officials said that the delay was due to technical difficulties. In a tweet, BMRCL said that the trains were plying slowly due to a honeycomb formation near the Trinity Metro Station. The honeycomb was formed under the metro track's bridge near the Trinity Metro Station on pillar number 155.

According to a BMRCL official at the spot, the slider or the concrete slabs supported by a pillar, has moved from its original position. The engineers have been told to concretise the slider. Temporarily, a metal jack has been placed next to the pillar to support the slider. BMRCL workers will carry out repair works after 11 pm once the metro stops plying for the day. They have been told to finish the work in three days.
