Set to become India’s longest expressway, the Narmada Expressway is 1,350 kilometers long and features long-span bridges and tunnels passing through undulating terrain, rivers, and cities, compounded by challenging climate conditions. LN Malviya bid on the project and initially used conventional methods for conceptual design. However, they quickly realized they needed advanced 3D modeling and analysis technology to optimize alignment and geometry of the long-span bridge and high-speed highway design.

They selected OpenRoads Designer to model roadway alignment, and OpenBridge and STAAD to model the bridge structure and analyze hundreds of load combinations, ensuring the bridge could resist high water currents and wind pressure. Bentley’s applications improved overall design efficiency by 25% and boosted productivity by 40%, reducing bridge design time by 200 hours and saving costs and resource hours. The integrated solution provided accurate geometric calculations and streamlined coordination, facilitating clear communication of design intent and technical management throughout the project development stage.
