Monopiles vs. Group Piles in Marine Bridge Construction: A Comparative Case Study of the Mumbai Coastal Road Project
Year: 2025
Type: article
Abstract: The Mumbai Coastal Road Project (South) Package-1 includes major infrastructure such as a navigational bridge, interchanges, sea walls, and reclamation works, with one of the most complex components being foundation construction in the intertidal zone. This thesis examines the use of monopile foundations for bridge structures in this marine environment, comparing them to traditional group pile systems. Through a case study of the Mumbai Coastal Road Project, it evaluates structural performance, construction methods, environmental impact, and cost-efficiency. Results show monopiles offer advantages in reduced construction time, simpler logistics, and lower material use, particularly in moderate water depths with uniform soils. However, group piles remain preferable in complex loading and variable ground conditions. The study emphasizes the importance of site-specific analysis and contributes to the advancement of sustainable and efficient marine foundation systems.
