NHAI mandates drone-based progress measurement for highway packages above ₹200 crore
Open NHAIWhat changed
NHAI directed that UAV/drone surveys are the primary method for monthly physical progress measurement on all EPC and HAM packages with a contract value above ₹200 crore. The Independent Engineer must use drone-generated point cloud data and orthomosaic imagery as the reference for chainage-wise progress certification. Manual measurement books remain in use for smaller structures and culverts, but corridor-level earthwork and pavement progress must be drone-certified.
Action to take
Drone survey data now carries the same evidentiary weight as IE-countersigned measurement books for corridor-level quantities. If the IE's drone survey underestimates progress, raise a formal dispute within 7 days of the survey report. Ensure your survey team accompanies the IE's drone operator on every flight.
