New norms for NH & bridge works: Longer timelines, realistic deadlines

New Delhi: In a major change in policy, govt has increased the time allowed for construction of 6-10 km-long bridges across rivers such as Ganga and Brahmaputra to six years and for 2.5-6 km-long bridges on Mahanadi and Godavari to five years. The timelines have been revised from the current 24-30 months.

Similarly, the construction period has been fixed at two years for national highway projects costing up to Rs 500 crore, 30 months for Rs 500-1,500 crore projects, and three years for works costing over Rs 1,500 crore.

The change in the ‘normative construction period’ has been made after a gap of 13 years, learning from past experience of how the average time taken for completion of NH projects has been over four years against the standard timeline of 2.5-3 years. The revised timeline for construction will be applicable for all NH projects to be bid out from May 6.

In a circular, the road transport ministry said present guidelines — issued in 2013 — are derived from a legacy linear model that does not explicitly account for voluminous earthwork, leading to unrealistic construction period and resulting in additional cost and risk.

“Therefore, a need was felt to revise the existing guidelines based on scientific analysis, understanding of completed projects, and prescribe a realistic construction period for civil works at DPR and bid invitation stage,” the ministry said. It added that the new norm will improve predictability in completion of projects, reduce disputes, enhance value and quality of NHs, for realistic and bankable bids, better quality outcomes and improved investor confidence.



An additional six months time has been provisioned in the new norms for critical projects which involve multiple flyovers, tunnels or elevated structures. Similarly, an addition of 12 months has been provisioned for projects that involve cutting and slope stabilisation in hilly states.
