Thiruvananthapuram, Dec 7 (NationPress) A high-level investigation into the failure of a section of the under-construction flyover along NH 66 at Mylakkadu, near Kottiyam in Kerala's Kollam district, is set to commence today. It has come to light that a significant technical alert, issued four months prior, was reportedly overlooked.
This advisory originated from a four-member expert panel appointed by the NHAI after a similar structure collapsed at Kooriyad in Malappuram earlier this year.
Upon examining the Kollam Bypass–Kadambattukonam segment of NH 66, the committee identified serious construction deficiencies and alarmingly weak soil conditions at various sites.
In their findings, the committee remarked: "Similar issues are present along the under-construction protection wall in the Kollam Bypass–Kadambattukonam area as well. The soil is critically weak in several areas, with Standard Penetration Test (SPT) results at some locations as low as 0 or 1. This is extremely concerning. Unless the soil is reinforced, the wall currently under construction is in danger of collapsing."
The panel also recommended corrective actions, including soil fortification and structural enhancements.
However, the failure to execute these suggestions is now perceived as a pivotal factor contributing to the collapse, according to the panel.
The flyover's sidewall collapsed on the evening of December 5, creating significant craters on the adjacent service road and trapping several vehicles. Although there were no reported injuries, the event incited panic among the local residents and led to the closure of the affected area, causing major traffic disruptions on this crucial route.
As part of the investigation, a team of NHAI technical specialists from Delhi will arrive at the site today. This will be succeeded by a visit from NHAI Chairman Santosh Yadav on Monday to evaluate the damage and oversee the restoration progress.
Officials indicated that temporary traffic restoration along the affected service road is anticipated by Monday, pending safety evaluations.
In the meantime, punitive measures have been initiated against the involved agencies.
The contractor from Delhi, Shivalaya Construction Ltd, along with consulting firms Feedback Infra and Sathra Services, has been suspended from participating in NHAI tender processes for a month.
Point of View
It is vital to highlight the pressing need for stringent safety measures in infrastructure projects. The oversight leading to the Kollam flyover collapse is a stark reminder of the potential consequences when warnings are disregarded. Our commitment is to ensure that such incidents prompt necessary reforms to protect the public.
