Walking Tour: Foundation Reuse
Click on this link to view the walking tour route and learn more about the various projects.
In 2026 we will once again organize an inspiring walking tour through Amsterdam, focused on the interaction between urban heritage, underground structures, and contemporary geotechnical practice. This tour offers a unique opportunity to experience how historical infrastructure and buildings can be assessed, adapted, and reused to meet today’s technical, societal, and sustainability challenges.
Participants will explore characteristic parts of the city on foot, guided by experts who connect what is visible above ground to what lies beneath. Along the way, examples of long-standing urban structures will serve as a starting point for discussion on topics such as foundation behaviour, monitoring, assessment strategies, and life-extension of existing assets. The informal setting encourages exchange of experiences and dialogue between professionals from different backgrounds.
The program will combine short indoor sessions with outdoor walks, allowing ample time to observe, reflect, and discuss. By keeping the format flexible, the tour can adapt to current developments, new projects, and emerging insights in the field.
This walking tour is intended for professionals with an interest in geotechnics, structural assessment, asset management, and the sustainable reuse of existing urban infrastructure. It offers not only technical inspiration, but also the chance to connect with peers in a relaxed and engaging environment.
Further details on the program and locations will follow at a later stage.
