Network Survey Vehicle on highway — Jancy Labs NSV testing in Madurai Tamil Nadu for NHAI and Highways Department
Overview

What Is Network Survey Vehicle Testing?

Network Survey Vehicle (NSV) testing is a mobile pavement evaluation method. An NSV travels your road section and continuously records surface condition data — roughness, rutting, and cracking — against GPS chainage. Your project gets a precise, kilometre-by-kilometre condition profile that manual inspection cannot match.

Highway engineers and contractors who skip NSV surveys risk submitting Pavement Management System (PMS) data that NHAI or the Highways Department rejects outright — causing costly project delays. Jancy Labs conducts IRC SP 16-compliant NSV testing for highway projects across Tamil Nadu, producing reports that NHAI and the Highways Department (PWD) accept for pavement condition surveys and maintenance planning.

NSV Test List

Full NSV Test List

Jancy Labs conducts three core NSV tests on road sections. All tests follow IRC SP 16 and produce GPS-tagged, MoRT&H-format outputs:

01

Roughness — International Roughness Index (IRI)

IRC SP 16

Measures ride quality by recording vertical pavement surface deviations continuously as the NSV travels at survey speed. IRI is reported in m/km and is the primary pavement condition trigger for NHAI maintenance and overlay decisions.

  • Ride quality assessment per IRC SP 16 guidelines
  • Pavement maintenance trigger for NHAI DLP audits
  • Required input for PMS data submission
  • GPS-tagged, kilometre-by-kilometre IRI profile
02

Rut Depth Measurement

IRC SP 16

Measures transverse permanent deformation (rutting) of the pavement surface using laser-based profiling. Rut depth data identifies structural distress zones, overlay triggers, and sections requiring rehabilitation rather than routine maintenance.

  • Structural distress identification across the road section
  • Trigger parameter for overlay or rehabilitation decisions
  • Cross-sectional rut depth profile at specified intervals
  • Used in NHAI OMT contract performance monitoring
03

Cracking & Distress Detection

IRC SP 16

Automated image-based detection of surface cracking and pavement distress — classifying fatigue (alligator) cracking, longitudinal cracking, transverse cracking, and patching by location and severity across the full survey length.

  • % cracked area per section for PMS reporting
  • Fatigue, longitudinal & transverse crack mapping
  • Distress severity classification per IRC SP 16
  • GPS-tagged distress inventory for maintenance planning

Why Us

Why Choose Jancy Labs for NSV Testing?

We understand what NHAI reviewers look for — and we deliver reports that pass:

  • IRC SP 16 compliance — every output references the correct standard, so your submission meets NHAI's PMS data requirements without revision requests.
  • Qualified highway engineers sign all reports — not just technicians. Every NSV report carries the signature of a qualified highway engineer as required by NHAI and the Highways Department.
  • GPS-tagged chainage output — data links directly to your project alignment, simplifying DLP monitoring and enabling precise section-by-section maintenance planning.
  • NHAI and Highways Department (PWD) accept our reports — for pavement condition surveys, maintenance planning, and OMT contract monitoring.
  • MoRT&H-aligned data format — compatible with IHMMS submission requirements, eliminating reformatting delays before upload.
  • Fast turnaround — we understand tender and DLP deadlines don't wait. Speak to us before scheduling so we can confirm availability for your road section.
  • Hands-on OMT contract documentation experience — our team works with contractors, DPR consultants, and government departments across Tamil Nadu.
Why It Matters

The Risk of Submitting Uncertified NSV Data

Submitting uncertified or incomplete pavement survey data to NHAI can result in outright PMS submission rejection — or worse, financial penalties during performance audits under OMT contracts. EPC contractors and DPR consultants preparing NHAI bid documents regularly use our NSV data to establish baseline pavement condition before submission.

Additionally, departments increasingly require GPS-tagged, IRC SP 16-compliant NSV outputs — not manual walk-through surveys. A Jancy Labs NSV report gives your project team the verified, engineer-signed data that survives NHAI scrutiny at every stage of approval.

Questions

Frequently Asked Questions

Is Jancy Labs qualified to conduct Network Survey Vehicle testing?
Yes. Jancy Labs conducts IRC SP 16-compliant NSV testing for highway projects. Our highway engineers produce reports that NHAI and the Highways Department accept. We have hands-on experience with OMT contract documentation and work with contractors, DPR consultants, and government departments across Tamil Nadu. Our outputs follow MoRT&H pavement evaluation guidelines and IRC SP 16, making them compatible with IHMMS submission requirements.
Which NSV tests does Jancy Labs conduct?
Jancy Labs conducts three core NSV tests on road surfaces: Roughness measurement (International Roughness Index — IRI in m/km), Rut Depth measurement (transverse permanent deformation in mm), and Cracking & Distress Detection (% cracked area per section, with fatigue, longitudinal, and transverse crack mapping). Additionally, we provide GPS-tagged chainage output and MoRT&H-format reports compatible with IHMMS submission.
Are Jancy Labs NSV reports accepted by NHAI and Highways Department?
Yes. NHAI and Highways Department accept our NSV reports. Our outputs follow MoRT&H pavement evaluation guidelines and IRC SP 16, making them compatible with IHMMS submission requirements. Furthermore, our reports include GPS-tagged chainage data and are signed by qualified highway engineers — not just technicians. We recommend confirming the specific report format your department or project requires before commissioning the survey.
What is the International Roughness Index (IRI) in NSV testing?
The International Roughness Index (IRI) is a standardised measure of pavement ride quality — reported in m/km (metres per kilometre). A lower IRI value indicates a smoother, better-maintained pavement; higher values indicate rougher conditions that affect vehicle operating costs and ride comfort. NHAI uses IRI thresholds to trigger maintenance, overlay, and rehabilitation actions under OMT contracts. Jancy Labs' NSV measures IRI continuously across your road section, producing a kilometre-by-kilometre IRI profile referenced to GPS chainage — the format NHAI's PMS data submission requires.
What is rut depth and why does it matter in pavement surveys?
Rut depth is the depth of the permanent transverse depression (channel) worn into the pavement surface by repeated traffic loading — measured in millimetres. Rutting indicates structural failure of the pavement layers (base, sub-base, or subgrade) and is a critical trigger for rehabilitation decisions. NHAI uses rut depth thresholds in OMT contract monitoring to determine whether routine maintenance, overlay, or full reconstruction is required. Jancy Labs' NSV records rut depth using laser-based cross-sectional profiling as per IRC SP 16.
Can Jancy Labs conduct NSV surveys anywhere in Tamil Nadu?
Yes. Jancy Labs mobilises our Network Survey Vehicle across Tamil Nadu for road section surveys. We serve highway projects in Chennai, Madurai, Coimbatore, Trichy, Tirunelveli, Salem, Dindigul, and across the state — including national highways, state highways, and rural roads under PMGSY. Call +91-8680049004 to discuss your road section, chainage range, and scheduling before your submission deadline.
