India Reverts Seismic Code: Safety vs. Cost Debate Reignited

India has reverted to the 2016 seismic code, withdrawing the recently proposed 2025 draft amid significant debate. The 2025 version aimed for enhanced earthquake safety, aligning with international practices and incorporating advanced hazard assessment. However, concerns over its substantial cost increases and practical enforceability led to its withdrawal.

Experts are advocating for a balanced strategy. This approach seeks to enhance safety, particularly for critical infrastructure like hospitals and schools, and promote retrofitting of existing homes. The challenge lies in achieving robust safety standards without imposing prohibitive expenses on a developing economy and ensuring practical implementation.

While the 2025 draft introduced scientific advancements like quantified risk and detailed zoning, critics pointed to the steep rise in construction costs. For instance, a 10-storey building in Delhi could see design base shear increase by 40%, with critical structures facing even higher percentages. The practical application for young engineers also raised concerns.

The focus is now on developing a pragmatic path forward. This involves sequencing safety improvements effectively, targeting vulnerable areas, and strengthening national earthquake mitigation programs. The goal is to gradually move towards a safer built environment, ensuring capacity and compliance keep pace with new standards, rather than rushing potentially unmanageable reforms.
