The National Highways Authority of India (NHAI) plans to float bids for 124 highway and expressway projects worth Rs 3.4 lakh crore in the financial year 2025-26, PTI reported.
These projects will cover a total length of 6,376 km across the country.
Among the major projects in the pipeline is the 476-km Gorakhpur-Kishanganj-Siliguri corridor, which will be bid out under the Hybrid Annuity Model (HAM).
The Hybrid Annuity Model (HAM) is a method for developing infrastructure projects, particularly roads, where the government and private developers share financial and operational risks.
It combines aspects of the Engineering, Procurement, and Construction (EPC) and Build-Operate-Transfer (BOT) models.
Another key project, the 106-km Tharad-Deesa-Mehsana-Ahmedabad stretch (Package 1), will be tendered under the Build-Operate-Transfer (BOT) model.
This project includes the construction of service roads and grade-separated structures.
National highway projects are primarily executed under three models: BOT, HAM, and EPC.
In BOT and HAM projects, the concession period, including maintenance, ranges from 15 to 20 years, with the concessionaire responsible for upkeep during that time.
In the EPC model, the contractor is liable for maintenance during the Defect Liability Period of five years for bituminous roads and ten years for concrete pavements.
