NHAI will conduct special quality inspections on 17 highway projects valued above ₹500 crore where accepted bids were over 15% below estimates and work is 35–80% complete.

New Delhi, October 1, 2026: The National Highways Authority of India (NHAI) has begun a special quality-inspection programme covering 17 under-construction National Highway projects where the accepted bid was more than 15% below the estimated project cost.
The inspections are in addition to NHAI’s regular quality-control process and are intended to identify construction-quality issues early enough for corrective action. According to the Ministry of Road Transport & Highways, the first round is scheduled to be completed by December 2026, followed by re-inspection of the same projects after six months by a different team of experts.
The initiative is significant for contractors and consultants because NHAI has explicitly linked the enhanced scrutiny to projects with unusually low quoted bids, while also making clear that the inspections will assess compliance against approved drawings, technical specifications, contract conditions and project-specific quality plans.
NHAI says the 17 projects were selected using three criteria:
The selected projects include greenfield and access-controlled corridors, bypasses and four- and six-laning works across Karnataka, Madhya Pradesh, Chhattisgarh, Andhra Pradesh, Tamil Nadu, Punjab, Haryana, Gujarat and Uttar Pradesh.
The authority has not said that a low bid automatically indicates poor construction quality. The additional inspections are instead a risk-based monitoring measure applied to projects that combine large contract values, significant bid discounts and a stage of execution where quality issues can still be identified and corrected.
The inspection teams will compare ongoing works against approved drawings, project specifications, contractual requirements and quality plans.
NHAI says the checks will cover the quality of construction materials, workmanship, construction methods and records relating to sampling and testing. Road-safety provisions, traffic management and environmental safeguards will also be reviewed where applicable.
Any work found to fall short of required standards is expected to be followed up for corrective action under the relevant contract provisions.
The programme is therefore broader than a visual site inspection. It extends into the quality-assurance systems contractors use to document materials, process control, testing and compliance during execution.
NHAI has created a pool of specialists for the programme. The inspections will be carried out by teams led by 39 experienced and retired engineers drawn from organisations including the Ministry of Road Transport & Highways, Ministry of Railways, Ministry of Defence and State Public Works Departments.
Technical experts will support the inspection teams during site reviews.
The first inspection cycle is targeted for completion by December 2026. NHAI then plans to conduct a second inspection of the identified projects after six months using different teams, creating a follow-up mechanism rather than a one-off audit.
Equipment Brief analysis: the new inspection programme increases the importance of documented quality control on large road projects, especially where competitive bidding has produced substantial discounts to the authority’s estimate.
For contractors, this means that cost discipline cannot be separated from compliance with material specifications, compaction requirements, pavement quality, concrete standards, workmanship and safety provisions.
It may also increase the operational importance of site laboratories, testing equipment, survey systems, digital quality records and process-control tools. However, the NHAI announcement is a quality-governance measure, not a forecast of equipment demand, and it does not specify any mandatory new machinery requirement.
The practical implication is stronger scrutiny of whether the construction process and supporting records demonstrate compliance throughout execution.
The distinction between bid level and construction quality is important.
An aggressive financial bid can reflect a contractor’s cost structure, procurement strategy, construction method, financing assumptions or competitive positioning. It does not establish by itself that the contractor will fail to meet technical standards.
NHAI’s approach is therefore best understood as targeted risk monitoring: projects with large values, deep bid discounts and significant physical progress receive an additional layer of review so that any issue can be detected before completion.
That distinction also matters in reporting procurement stories. Equipment Brief separates tender value, quoted bid, L1 status, award value and execution-stage performance rather than treating them as interchangeable measures.
Projects in the 35–80% physical-progress range are far enough into execution for workmanship, material use and construction methods to be assessed across meaningful sections of work, but not so close to completion that corrective intervention becomes difficult.
The chosen range therefore gives NHAI an opportunity to evaluate quality during active construction rather than after the asset has already been substantially completed.
For contractors and consultants, this reinforces the need to maintain continuous quality documentation rather than relying only on completion-stage certification.
The immediate milestone is completion of the first inspection round by December 2026.
NHAI has not published the full project-wise list in the press release, nor has it identified any specific contractor or project as having failed a quality test. Equipment Brief will therefore not attribute quality deficiencies to individual projects unless NHAI subsequently publishes project-specific findings.
The more important industry development will be whether the inspection programme leads to recurring quality findings, corrective directions, contractual action or broader changes in how NHAI monitors aggressively priced projects.
For wider road-sector context, Equipment Brief is also tracking the Hyderabad–Vijayawada NH-65 tender, the Dilip Buildcon Solapur NH-65 L1 position and its guide to road-construction equipment.
