As many as 377 infrastructure projects, each worth Rs 150 crore or more, have been hit by cost overruns of more than Rs 3.94 trillion owing to delays and other reasons, according to a report.
The Ministry of Statistics and Programme Implementation monitors infrastructure projects worth Rs 150 crore and above.
Of such 1,635 projects, 377 projects reported cost overruns and 565 projects time escalation.
"Total original cost of implementation of the 1635 projects was Rs 19,47,462.67 crore and their anticipated completion cost is likely to be Rs 23,41,784.84 crore, which reflects overall cost overruns of Rs 3,94,322.17 crore (20.25 per cent of original cost)," the ministry's latest report for September 2019 said.
According to the report, the expenditure incurred on these projects till September 2019 was Rs 9,96,613.94 crore, or 42.55 per cent of the anticipated cost of the projects.
However, it said the number of delayed projects decreases to 495 if delay is calculated on the basis of the latest schedule of completion.
Further, it said that for 693 projects neither the year of commissioning nor the tentative gestation period has been reported.
Out of 565 delayed projects, 182 projects have overall delay in the range of 1 to 12 months, 129 projects 13 to 24 months, 140 projects reflect delay in the range of 25 to 60 months and 114 projects show delay of 61 months and above.
The average time overrun in these 565 delayed projects is 38.41 months.
The brief reasons for time overruns, as reported by various project implementing agencies, are delays in land acquisition, forest clearance and supply of equipment.
Besides, there are other reasons like fund constraints, geological surprises, geo-mining conditions, slow progress in civil works, shortage of labour, inadequate mobilisation by the contractor, Maoist problems, court cases, contractual issues, ROU/ROW (right of use/right of way) problems, law and order situation, among others, the report said.
It also observed that project agencies are not reporting revised cost estimates and commissioning schedules for many projects, which suggests that time/cost overrun figures are under-reported.
