The transfer of technology from research to structural engineering and construction practice is illustrated using two cases of the implementation of innovative engineering methods and technologies in the renewal and 'upcycling' of existing bridges, namely monitoring-based structural verification and the Ultra-High Performance Fiber Reinforced Cementitious Composite (UHPFRC) technology to improve existing structures. Implementation of the novel UHPFRC technology in construction practice in Switzerland is analyzed to derive the decisive conditions for technology transfer. Technology transfer is primarily a question of behavioral psychology of the professionals involved in innovative projects and not merely a question of scientific and technological knowledge and know-how. Publishing research in peer-reviewed journals is of fundamental importance, but is not sufficient for putting new technologies into practice and to foster innovative structural engineering projects. Finally, change in the education of structural engineers is proposed, including new courses on engineering of existing structures, the culture of structural engineering and training to promote innovation.
