Government Revises Construction Timelines for Major Infrastructure Projects
In a significant policy shift, the government has announced extended construction periods for large-scale infrastructure projects, including bridges over major rivers and national highways. This move aims to address historical delays and enhance project predictability.
Extended Timelines for River Bridges
The construction period for bridges spanning 6 to 10 kilometers across rivers such as the Ganga and Brahmaputra has been increased to six years. Similarly, for bridges measuring 2.5 to 6 kilometers on rivers like the Mahanadi and Godavari, the timeline has been set at five years. These revisions mark a substantial change from the previous standard of 24 to 30 months, reflecting a more realistic approach to complex engineering challenges.
Revised National Highway Construction Periods
For national highway projects, new construction timelines have been established based on cost brackets. Projects costing up to Rs 500 crore will now have a two-year construction period. Those in the Rs 500 to 1,500 crore range are allocated 30 months, while projects exceeding Rs 1,500 crore will be granted three years. This structured approach replaces the older guidelines, which often led to unrealistic expectations and prolonged delays.
Background and Rationale for the Change
The revision in the 'normative construction period' comes after a 13-year gap, informed by past experiences where the average completion time for national highway projects exceeded four years, against the standard 2.5 to 3 years. The road transport ministry, in a circular, highlighted that the 2013 guidelines were based on a legacy linear model that failed to account for voluminous earthwork, resulting in additional costs and risks.
The ministry stated, "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 the Detailed Project Report (DPR) and bid invitation stage."
Benefits of the New Norms
The updated guidelines are expected to bring several advantages, including improved predictability in project completion, reduced disputes, enhanced value and quality of national highways, and more realistic and bankable bids. This is anticipated to boost investor confidence and lead to better quality outcomes in infrastructure development.
Additional Provisions for Complex Projects
Recognizing the complexities of certain projects, the new norms include extra time allowances. Critical projects involving multiple flyovers, tunnels, or elevated structures will receive an additional six months. Furthermore, projects requiring cutting and slope stabilisation in hilly states will be granted an extra 12 months, ensuring safety and feasibility in challenging terrains.
Implementation Details
The revised construction timelines will apply to all national highway projects bid out from May 6, 2024. This policy update is part of broader efforts to streamline infrastructure development and align with practical on-ground realities, ultimately fostering a more efficient and reliable construction ecosystem in India.
