The National Highways Authority of India (NHAI) has moved to empanel Indian Institutes of Technology (IITs) and other reputed technical institutions for independent proof checking of hydraulic studies and design of major bridge structures across national highway projects in all new projects. The measure aims to strengthen safety, quality and long-term durability of the National Highway network by ensuring major bridges designed for a service life of 100 years or more undergo rigorous independent technical review prior to construction. The initiative is intended to add an additional layer of assurance to engineering decisions on critical structures.

Around 12 IITs, including Indian Institute of Technology Delhi, Indian Institute of Technology Bombay, Indian Institute of Technology Roorkee and Indian Institute of Technology Kharagpur, along with several premier technical schools, have indicated willingness to collaborate with NHAI. The empanelment is expected to create a pool of external experts capable of scrutinising structural proposals and hydraulic assessments prepared by project consultants. Institutions on the panel will be required to apply standardised vetting protocols and document their findings for inclusion in project records.

The framework will mandate independent review of structural design calculations, engineering drawings, construction methodologies, geotechnical investigations and hydraulic studies for major bridge schemes. Reviews will cover both conceptual and detailed design stages and will assess assumptions, loadings and design life parameters to reduce the risk of design defects being carried into construction. The process seeks to harmonise design practices across contracts and delivery modes so that similar standards apply whether projects are delivered through public funding, public-private partnerships or other formats.

Authorities anticipate that institutional proof checking will significantly enhance structural safety, improve design reliability and minimise long-term operational risks across the highway network. The move aligns with NHAI's broader objective of adopting best-in-class engineering practices and institutional mechanisms to support development of a future-ready National Highway network. Officials expect the framework to strengthen quality assurance and promote better execution of critical bridge projects nationwide.
