Vellore: A major structural failure occurred in Tamil Nadu's northern border belt when the upper concrete roof slab and support framework of an under-construction Church of South India (CSI) structure caved in at Mandai Krishnapuram near Katpadi in Vellore district. The accident took place while workers were actively pouring wet concrete for the church's upper ceiling, causing a 20-foot steel scaffolding structure to give way under the heavy wet load and trapping over a dozen labourers beneath twisted iron bars and slurry. Following an intensive overnight joint emergency operation led by the National Disaster Response Force (NDRF) alongside Tamil Nadu and Andhra Pradesh state agencies, authorities officially concluded rescue operations, confirming three fatalities and 11 injured.

  • Deceased Identified: The deceased have been identified as building contractor John (39) from Bengaluru, alongside daily-wage construction workers Immanuel (45) and Samuel (45) from neighbouring Andhra Pradesh.
  • Hospitalisation of the Injured: Eleven rescued workers were transported via emergency ambulances to the Vellore Government Medical College Hospital at Adukkamparai, the Christian Medical College (CMC) Hospital in Vellore, and a government medical facility in Chittoor, Andhra Pradesh, with several undergoing trauma surgery for crush fractures.
  • Cross-Border NDRF Deployment: A 38-member specialized disaster rescue unit equipped with canine squads from the NDRF 4th Battalion base in Arakkonam was dispatched to the crash site, utilizing hydraulic spreaders and concrete cutters to clear subterranean voids and reach trapped victims.

District Administration Orders Structural Probe and Police File FIR

Visiting the site to inspect the rescue work, Vellore District Collector P. S. Leela Alex announced swift administrative and regulatory investigations:

  • Technical Inquiry Committee: The district administration has constituted an expert engineering committee to evaluate structural load calculations, verify the tensile strength of the centering props, and inspect whether the church administration secured mandatory planning permits and municipal structural stability clearances.
  • Criminal Negligence Case: The Thiruvalam police station has registered a First Information Report (FIR) under sections of the Bharatiya Nyaya Sanhita (BNS) concerning acts endangering personal safety and causing death by negligence against the structural engineers and on-site building supervisors.
  • Inter-State Relief Coordination: Because multiple deceased and injured workers hail from border villages of Andhra Pradesh, Chittoor district administration officials liaised directly with Tamil Nadu counterparts to expedite ex-gratia relief disbursal and streamline medical management.

Scaffolding Norms and Construction Safety Oversight

Civil engineering bodies and local civic activists across northern Tamil Nadu have raised serious concerns regarding non-standard centering practices during large-span institutional slab castings. Structural experts emphasized that multi-tiered temporary scaffolding must undergo mandatory engineering load-testing prior to pouring wet concrete, demanding stricter regulatory inspections to prevent preventable work-site tragedies.
