BENGALURU: After a honeycomb formation in a viaduct beam close to Trinity Metro Station final December, another structural flaw has come into light on pillar no. 67 close to South End Circle Metro Station.
TOI confirmed photos of the construction to mavens at Indian Institute of Science (IISc). “The cracking is within the seating portion of the pot bearing. The girder needs to be lifted and the pot bearing reset at the identical location in a brand new concrete seating and put below observation. The reason why for the cracking needs to be assessed,” explained professor Ananth Ramaswamy, civil engineer from IISc.
He stated BMRCL needs to investigate the reason for the cracking. South End Circle station close to Basavanagudi on the Green Line is operational since June 2017.
Experts say pot bearing is a vital a part of a construction as it takes the pressure and distributes it calmly. However, it’s susceptible to put on and tear. The development as soon as again exposes the deficient high quality of construction and insufficient inspections.
BMRCL managing director Ajay Seth, on the other hand, stated: “It’s no longer a crack within the pillar. The bearing pedestal was built in two layers. On considered one of its faces, the development joint is visible. It’s no longer a crack within the pedestal also. Action is being taken to wait to the skin joint. There’s no implication on the construction’s protection.”
On December 9, 2018, BMRCL had detected “a minor aberration in girder alignment” following a honeycomb concreting defect — hole spaces in precast concrete — in a viaduct beam above pier 155 close to Trinity Station. BMRCL resources admitted it was negligence during construction that resulted within the honeycomb formation.
Following the incident, deputy chief minister G Parameshwara had directed BMRCL to investigate cross-check all structures alongside Phase 1 Metro routes to make sure protection of passengers. BMRCL officials stated they'd use ultrasonic technology to evaluate protection of the structures. However, the reports are but to be made public.
Usually, BMRCL conducts structural inspections every year or two. Bangalore Metro Rail Employees Union (BMREU) stated there’s a shortage of civil engineers to do high quality assessments. Union vice-president Surya Narayana Murthy stated BMRCL lacks certified engineers to make sure protection and maintenance of structures. “Such structural defects could have been identified a lot earlier if there have been adequate engineers and common inspections were performed,” he stated.
