NEW DELHI: With its operational network within a touching distance of 400km — and a large section built 15 to 20 years ago — Delhi Metro Rail Corporation (DMRC) is going to replace the manual inspection by a drone survey.
“DMRC will use drone for inspection as an advance means for a better view and access, doing away with the manual mode of inspection that takes more time and labour,” a spokesperson said. “The inspection will be done in a phased manner at all elevated sections,” he added.
