**We are a specialized engineering firm committed solely to bridge engineering and dedicated to providing clients with cost-effective and constructible solutions. **

As a wholly owned subsidiary of the SYSTRA Group, a global leader in transport
infrastructure design, we’re part of a network of over 350 bridge engineering
specialists deployed worldwide. SYSTRA International Bridge Technologies is a
cornerstone of SYSTRA Bridges, which comprises our offices in the United States,
Canada, and the Middle East, as well as SYSTRA’s bridge design hubs throughout
the world.

At SYSTRA IBT, our team of professionals has extensive experience in all facets
of bridge design, construction, and maintenance. We’ve partnered with
transportation authorities, general contractors, and multi-disciplinary
engineering firms, including being Engineer-of-Record for both traditional
design-bid-build and design-build projects. Our bridge projects extend to
various countries, including the United States, Canada, Panama, Australia,
India, Jamaica, Mexico, Taiwan, and the Middle East.

We are dedicated exclusively to the design and engineering of a variety of
bridge types. Our expertise lies in niche areas such as steel-concrete composite
and all concrete cable-stayed structures, extradosed structures, and segmental
concrete bridges.

Additionally, our team is renowned globally for our expertise in elevated
guideway design for metro and high-speed rail projects. Our colleagues in SYSTRA
Bridges also bring in valuable references in the design of suspension bridges,
arches, and truss bridges, as well as for their successful design of over 280
miles (450 km) of elevated guideways using SYSTRA’s patented U-shaped viaduct.
Moreover, SYSTRA continues its ascent in the Engineering News-Record (ENR)
rankings, holding the 3rd position in the International Bridges Category for the
year 2024.

SYSTRA IBT is committed to providing our clients with solutions that are
tailor-made for their specific needs and site requirements. Our approach
emphasizes the importance of producing bridges that are both cost-effective and
constructible without compromising on quality or aesthetics.

### A Legacy of Engineering Excellence

SYSTRA International Bridge Technologies’ values are deeply rooted in a
mentor-apprentice tradition that has shaped the world of bridge engineering for
generations. Today, we carry on a legacy of technical achievement and the
creation of beautiful structures, honoring the innovative work of those who laid
the foundation for what is viable in bridge engineering.

### A Bridge Engineering Icon

At the core of our legacy lies the late Jean M. Muller, who was one of the
greatest bridge engineers of the 20th century. Muller’s contributions to bridge
engineering are nothing short of legendary. He is credited with the development
of the match-casting technique, a breakthrough innovation widely used in modern
precast concrete segmental construction. His visionary design for the Brotonne
Bridge in Normandy, France, featuring a 1050-ft main span supported by a single
plane of cable stays, marked a turning point in bridge engineering. He also
introduced the delta frame concept, a groundbreaking approach to widening
segmental cable-stayed bridges, allowing them to accommodate more traffic lanes
without compromising structural integrity. Muller’s mentor, Eugène Freyssinet,
is often regarded as the inventor of modern prestressed concrete.

### Continuing the Legacy

From 1972, Daniel Tassin, co-founder of International Bridge Technologies, had
the privilege of working closely with
[Mr. Muller](https://www.systra.com/ibt/wp-content/uploads/sites/21/2023/10/dtassin_article_jean_m_muller_bridge_engineer_2006.pdf)
for an impressive 25 years. Daniel served as the Chief Engineer for the iconic
Sunshine Skyway Bridge in Tampa, Florida, leaving an indelible mark on the world
of bridge construction. His career continued to soar as he became involved in
some of the largest and most challenging bridge projects worldwide.

In 2000, International Bridge Technologies was founded, establishing itself as a
renowned California-based firm specializing exclusively in bridge engineering.
Under Daniel’s guidance, who served as both IBT’s President and Technical
Director, the company embarked on a 17-year journey characterized by remarkable
accomplishments, solidifying IBT’s position as a leader in cutting-edge bridge
engineering. He is still active in the firm and serves as Senior Technical
Advisor for SYSTRA IBT.

**Prior to starting International Bridge Technologies, Inc., Daniel Tassin was involved in several remarkable projects: the Houston Ship Channel Bridge and the Sunshine Skyway Bridge**
**with Figg & Muller Engineers; the H3 Windward Viaduct in Hawaii, the Bangkok Transit System and Bang Na Expressway in Thailand, the Confederation Bridge and Vancouver Millennium Light Rail in Canada, all with J. Muller International.**

### Dynamic Synergy

IBT joined forces in 2017 with SYSTRA, a global leader in public transport and
mobility engineering. This strategic partnership was a pivotal moment in our
history, one that brought together two pillars of expertise to form SYSTRA
International Bridge Technologies. Together, we expanded our core capabilities
to offer clients an all-encompassing approach that combines technical service,
excellence in innovation, and an unwavering commitment to safety and ethics. The
integration was not just about joining two entities; it was about creating a
dynamic synergy that would shape the landscape of transportation infrastructure
worldwide.

### Forwarding a Legacy

The success of SYSTRA IBT can be attributed to the pioneering work of our
mentors. While segmental construction techniques are now commonplace, they
remain intricate and demanding. SYSTRA IBT has navigated through the same
challenges that were once considered unproven technology, developing leaders
thanks to the knowledge and guidance passed down from the Muller-Tassin duo.
This wealth of experience and expertise has enabled SYSTRA IBT to extend across
a diverse spectrum of bridge types, each presenting unique challenges. Our
engineers today are inspired and remain dedicated to carrying forward the legacy
of innovation. They continue to push the boundaries of bridge engineering,
creating structures that leave a lasting mark on the world.
