The Kolkata Police arrested four more officers of the IVRCL on Monday in connection with the Vivekananda Road flyover collapse incident that left more than two dozen people dead.
Company’s director (operations) Gopal Krishna Murti, DGM (project) SK Ratnam, engineers Shyamal Manna and Bidyut Manna were detained for interrogation and were later arrested after the police found anomalies in their statements.
With these four, altogether eight officials of the company have been arrested in connection with the tragedy.
Earlier, IVRCL AGM Mallikaarjun Rao, assistant manager Debjyoti Manjumdar, structure manager Pradip Kumar Saha and project manager Tanmoy Sil were also arrested under IPC Sections 302 (murder), 307 (attempt to murder) and 120B (criminal conspiracy) and others.
Meanwhile, police sources claimed the contractor company did not implement a proper quality assurance plan (QAP) while constructing the flyover.
The labourers too, who were on spot at the time of accident, claimed that despite raising an alarm, the engineers did not paid any heed to their advice on safety measures.
“As per company records we managed to retrieve, IVRCL did adhere to the rules of transport ministry and even formulated a QAP at the initial stages. But over the years, as the company hit various stumbling blocks, endlessly pushing back the deadline, it forgot about the QAP. It should be considered as a major negligence,” said a police officer.
QAP is very important for any project as it sets quality of the construction procedure and it also helps to monitor and control the level of quality of materials used. QAP also ensures extensive mandatory laboratory tests so that no substandard material is used.
“It means that QAP ensures safe infrastructure but IVRCL never considered it necessary to monitor and test the materials supplied by the sub-contractor Sandhyamoni Projects Limited. The sub-constructor constructed the slab only once before it collapsed,” an investigating officer added.
“The flyover project was awarded to the company in February 2009 and its troubles began when Burrabazar residents moved court for a stay order against the proximity of the structure to their homes. The long delays started leading to construction flaws and the company suddenly stopped concentrating on the QAP,” said a police officer.
