As a first step towards this task, preparation of Detailed Project Reports is being undertaken by NHAI. In the first phase, DPRs of identified 15000 km is proposed to be prepared. In LOT1, NHAI has invited bids for preparation of DPRs for 15,000 km of length in the country. Bids have been invited in 45 packages of about 300 Km length each.
In order to drastically reduce the time taken for conducting surveys, it has been decided to use latest technologies such as LiDAR, Satellite mapping and Ground Penetration Radar (GPR) in preparation of DPRs. This will also help to make data collection comprehensive with accurate measure points and increase the safety for project personnel.
