Designing of Bridge No. 20 - Bandra Mumbai

Location: Mumbai, India Client: Indian Railways

Casad Services: Detailed Planning and Designing of Bridge

---

Project Overview The project involved the critical reconstruction of Bridge No. 20, a historic railway bridge located between Bandra and Mahim stations in Mumbai. This 135-year-old structure, one of the last remaining British-era screw-pile bridges on the Indian Railways, was replaced with a modern, robust concrete bridge to ensure passenger safety and operational reliability. The project was executed under the purview of Western Railway.

Casad's Scope of Work The comprehensive scope of work for this project included:

• Detailed Planning and Designing of Abutment & Pier of Bridge: Planning and designing the bridge's main supports, including the abutments and piers.

• Design of Cofferdam & Protection Pile : To allow construction to proceed safely in or near water, a temporary enclosure called a cofferdam was designed. Additionally, protection piles were designed to safeguard the cofferdam and the permanent bridge foundation from impacts from water currents, debris, or passing vessels.

• Design of Temporary Abutment for Relieving Girder & New Abutment A1: Designing a cofferdam and protection piles for safe construction in the river, as well as a temporary abutment to allow train traffic to continue during the rebuilding process.

• Design of Strengthened Existing Pier P1: Providing a design to strengthen the existing Pier P1, ensuring its durability and ability to support future loads.
  

Capabilities in Action This project demonstrates expertise in:

• Complex Civil and Structural Engineering: The ability to replace a historic, failing structure with a modern, safe, and durable concrete design.

• Urban Infrastructure Management: Efficiently executing a large-scale project in a highly congested metropolitan area with minimal disruption to essential services.

• Comprehensive Project Delivery: The capacity to manage all facets of a major construction project, from initial design and documentation to visualization and final implementation.
