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 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 Millenium Light Rail in Canada all with J. Muller International.
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.
