Project Overview
CASAD Consultants served as the primary structural and engineering consultants for the Lalpur Bypass Flyover project in Jamnagar, Gujarat. Spanning a total length of 1,000 meters, this key urban arterial grade separator is engineered to relieve severe traffic congestion at the Lalpur Bypass junction. The design incorporates curved prestressed concrete (PSC) girders and specialized substructure framing to ensure seamless multi-level traffic movement while supporting high-capacity heavy vehicular loads.
Key Technical Details
Structural Footprint & Scale: 1,000-meter total elevated length incorporating complex curved deck geometry and transition approach ramps.
Superstructure Engineering: Custom-designed Prestressed Concrete (PSC) girders optimized for deck curvature, torsional resistance, and long-term durability.
Advanced Substructure System: Utilizes portal-type piers and split-pier supports fitted with elastomeric bearings anchored on high-load deep pile foundations for optimal load transfer and underpass clearance.
Casad's Scope of Work
End-to-End Structural Design & Engineering: Executed comprehensive structural modeling, finite element analysis (FEA), and detailed engineering drawings for superstructures, substructures, and foundation systems.
Feasibility & Geometric Alignment Studies: Performed initial engineering feasibility assessments and detailed horizontal/vertical alignment design to integrate deck curvature smoothly into existing road networks.
Advanced Substructure & Foundation Modeling: Engineered specialized portal-frame piers and split-pier configurations to maintain unobstructed ground-level traffic lanes during and post-construction.
Technical Approvals & Proof Consulting: Led statutory coordination and secured formal technical sanction approvals from municipal and state road transport authorities.
Capabilities in Action
Curved Elevated Highway Design: Proven technical capability in engineering complex PSC girder superstructures featuring horizontal curvature and non-linear deck geometry.
Substructure Innovation for Urban Corridors: Expertise in deploying portal and split-pier structural systems to minimize ground footprint while maximizing underpass vehicular clearance.
Full Lifecycle Infrastructure Consultancy: Demonstrated proficiency in delivering seamless end-to-end consulting—from pre-feasibility planning and structural design to technical proof-checking and site validation.
