Project Overview

The Khokhra Railway Overbridge is a landmark steel truss bridge constructed to span one of the busiest railway corridors in India. Designed for high-traffic urban mobility, the bridge features a single-span steel superstructure measuring 92 meters—the longest of its kind in Western Railway—and weighs an impressive 1045 metric tonnes.

Launched over live railway tracks, this project demanded precision engineering, seamless planning, and zero room for error, making it a flagship example of complex infrastructure delivery.

The Khokhra ROB stands as a testament to Casad Infra Solutions’ ability to deliver complex, large-scale infrastructure with precision, safety, and structural excellence by:

• Enabling safe, on-time execution of a critical urban bridge under challenging live-track conditions.

• Setting a record as the longest and heaviest single-span steel girder in Western Railway history.

• Demonstrating Casad’s bridge engineering expertise in high-stakes infrastructure, integrating BIM and structural design seamlessly.

Casad's Scope of Work

Casad Infra Solutions was entrusted with the complete structural engineering services, ensuring both technical excellence and execution efficiency:

• Steel Bridge Design: Structural analysis and design of the 92 m span steel truss bridge under railway loading conditions.

• Fabrication Drawings: Preparation of workshop-ready fabrication drawings compliant with Indian and railway standards.

• TEKLA 3D Modeling: Advanced BIM modeling using TEKLA Structures for constructability, clash-free connections, and coordinated steel detailing.

• Erection Planning Support: Sequence modeling and coordination for safe and efficient girder launching over operational railway lines.

Capabilities in Action

• Large-Span Steel Structures: Engineered India’s longest single-span girder over railway tracks (92m).

• Live Track Coordination: Delivered launch-ready engineering with zero disruption to Western Railway’s operations.

• Precision Detailing with TEKLA: Generated clash-free shop drawings and ensured fabrication-ready outputs for on-ground teams.

• End-to-End Engineering Support: From structural analysis to launch sequencing, Casad offered holistic support.
