How could NHAI's new independent design checking policy affect IRC?
The Indian Roads Congress may see strengthened adherence to its standards on national highways The National Highways Authority of India (NHAI) has introduced a policy requiring independent verification of designs for major highway structures, starting December 1. This verification process, which utilizes empanelled Indian Institutes of Technology (IITs) and other firms, explicitly aims to ensure that all structures meet applicable Indian Roads Congress (IRC) codes and technical specifications. By mandating this rigorous, third-party review for critical structures—such as major river bridges with a design discharge of 3,000 cubic metres per second or more—the policy formalizes and strengthens the practical enforcement of IRC standards across India's largest infrastructure projects.

How it reaches IRC
-
The National Highways Authority of India introduced a new policy requiring independent design checking for major bridges and critical structures under its projects. This system applies to all new Engineering, Procurement and Construction, Hybrid Annuity Model, and Build-Operate-Transfer National Highway projects starting December 1. Empanelled Indian Institutes of Technology, government technical institutions, and experienced technical firms will verify designs against Indian Roads Congress codes. The policy specifically covers major bridges with a design discharge of 3,000 cubic metres per second or more.
The full event1independent outlet -
Under this new framework, the independent checking process must ensure that structures meet applicable Indian Roads Congress (IRC) codes, technical specifications, and contractual requirements. This applies to major bridges and viaducts, including those with an individual effective span of at least 40 metres. The formalization of this independent verification process, which involves technical institutions like IITs, strengthens the practical adherence and enforcement of the standards set by the IRC across NHAI's national projects.

Why it matters
For the Indian Roads Congress, this policy represents a significant institutional validation of its standards. As the primary body setting the technical specifications for national highways, the mandate from NHAI to use independent checks specifically against IRC codes ensures that the standards are not merely theoretical guidelines but are rigorously applied and verified in the field. This increases the visibility and practical authority of the IRC's technical framework.
This move is part of a broader effort by NHAI to strengthen safety and quality assurance across its massive infrastructure portfolio. The policy requires independent verification not only of structural design but also of hydrological and hydraulic studies, ensuring a comprehensive application of engineering principles and standards across all critical components of the national highway network.
What we don't know yet
- Will the independent checking process lead to a measurable increase in the number of design revisions required for major projects?
- How will NHAI manage the potential conflicts or disagreements between the contractor's design and the observations submitted by the empanelled IITs?
