Bridges & Flyovers

Bridges mean one word: connectivity. Perhaps the most important form of infrastructure for human connectivity and transport, the significance and necessity of bridges cannot be understated. That’s why bridges end up being landmarks more often than not – from the Tower Bridge in London to the Golden Gate Bridge in San Francisco, from Brooklyn Bridge in New York City to Howrah Bridge in Kolkata, bridges and flyovers transcend time and travel in more ways than one.

To create such everlasting, landmark structures, It is absolutely essential for the builders to have the right design skills and structural knowledge. Building a bridge that stands for generations is no mean feat.

For over four decades, our dedicated team of structural engineers has been at the forefront of bridge and flyover design, delivering safe, durable, and aesthetically pleasing structures that stand the test of time. We excel in all-round design, building and maintenance of bridge and flyover structures:

Design & Engineering: From concept development to detailed design, we provide comprehensive engineering solutions for all bridge types and complexities. Our designs optimize structural performance while considering constructability, maintenance requirements, and lifecycle costs.

Inspection & Rehabilitation: Our bridge assessment services help identify structural deficiencies and develop effective rehabilitation strategies. Using advanced NDT techniques and structural analysis, we extend the service life of existing structures while ensuring public safety.

Construction Support: We provide expert guidance throughout the construction process, offering technical support, shop drawing review, and quality assurance services to ensure that bridges are built according to design specifications and industry standards.

Project Delivery Process

1. Needs Assessment

We begin by understanding your project objectives, constraints, and performance requirements. This includes traffic analysis, site investigation, and stakeholder consultation to establish clear project goals.

2. Concept Development

Our team develops multiple bridge concepts, considering structural systems, materials, aesthetics, constructability, and lifecycle costs. We work closely with you to select the optimal solution.

3. Detailed Design

We translate concepts into comprehensive designs, including structural analysis, foundation design, material specifications, and detailed drawings. Our designs comply with relevant codes while optimizing performance.

4. Construction Documentation

We produce detailed construction drawings, specifications, and cost estimates. Our documentation is clear, comprehensive, and tailored to facilitate efficient construction processes.

5. Construction Support

During construction, we provide technical support, review submittals, respond to RFIs, and conduct site inspections to ensure the structure is built according to design intent and quality standards.

6. Commissioning & Handover

We oversee testing, commissioning, and project closeout, providing maintenance guidelines and as-built documentation to support the long-term management of your bridge asset.
