To record and assess the condition of roads beneath the surface, vehicles equipped with NSV technology come with high resolution camera and laser-beam throwing capacity
Bihar road construction department (RCD) will now be using a “high precision laser-based technology” – (network survey vehicle) NSV technology for checking the quality of newly constructed roads and maintenance of old ones for saving time, cost and ensure accuracy in assessment.
As stipulated under the International Roughness Index (IRI), the department till now relied on manual verification of quality control measures that was not only time-consuming and costly but also prone to fudging. Now, it has decided to adopt the laser-based NSV technology, introduced recently for checking the quality of construction of national highways.
To record and assess the condition of roads beneath the surface, vehicles equipped with NSV technology come with high resolution camera and laser-beam throwing capacity. Bihar has around 5,000 km of national highways, 4000km of state highways and around 11,000km of major district roads.
Amrit Lal Meena, additional chief secretary at RCD, said the new NSV technology will also ensure that contractors are penalized suitably for not adhering to quality control measures. “Manual inspection of road is a vigorous exercise and costs a huge sum as road maintenance was brought under the Bihar public grievances resolution rights act”, said Meena.
Empowering residents with the legal right for hearing of grievances, redressal and of communication on the decision taken, Bihar Right to Public Grievance Redressal Act 2015 makes it incumbent on the government agencies to deliver a set of services within a stipulated time.
Meena said, after Nitin Navin, Minister of RCD, during a recent meeting to review various undergoing road projects, asked for speedy disposal of complaints related to poor maintenance of roads, the department decided to adopt the NSV technology.
Accordingly, for faster and digitized survey of roads for their timely maintenance, the executive engineers of the department have been told to engage among 41 firms, empanelled by the Union ministry of road transportation and highways (MoRTH).
Under the RCD’s maintenance policy, contractors are obligated to maintain roads for seven years after its completion. Meena said the policy also had provisions for high-level inspection of the projects.
