The government saved over 12 per cent in construction cost against estimates in awarding contracts of Urban Extension Road-II or Dwarka Expressway, and CAG findings that the cost was exorbitant are misplaced as the auditor did not factor in the actual cost, top sources in the road transport ministry said. According to reports, the Comptroller and Auditor General (CAG) had found that the National Highways Authority of India’s (NHAI) decision to go for an elevated carriageway on the Haryana portion of the Dwarka Expressway pushed up the construction cost to Rs 251 crore per kilometre from Rs 18.2 crore per km estimated earlier.
