The objective of this scanning tour was to conduct a broad overview of newly developed manufacturing techniques that are in use abroad for steel bridge fabrication and erection. The trip focused on the role of steel production, design, innovation, and fabrication in modern steel fabrication facilities in Japan, Italy, Germany, and the United Kingdom. The team also shared information on U.S. practice, initiatives, and research activities in these areas. As a result of the review, the team identified six high-priority areas on which the U.S. industry should focus: computer aided drawing and computer aided manufacturing; automated recording of inspection, welding variables, and geometric measurements for quality control and virtual assembly; high-performance steels and coatings; cutting and joining steel components, members, and structures; certification and contracting of steel fabrication and erection; and design innovation. Within each of these areas, the team made recommendations for further research, pilot studies, and modifications to existing procedures that will further modernize structural steel fabrication facilities in the United States.
