Introduction After the successful projects ‘Pykrete Dome’ and “Sagrada Familia in ice” ,we started to make new plans for the winter of 2016. Searching for a new challenge, we came to the conclusion that our sponsors and the community of Juuka in Finland, would be interested in an iconic building with a strong appeal. For us it had to be a new technical and scientifi c challenge. Combining these two starting points and based on the experiments of the last project, we came up with the idea to make a model of the never build Brigde over the Golden Horn by Leonardo da Vinci. A visit to the sources of the bridge in Milan in Italy, inspired us to what would become the final concept of a model based on the most important parts of this bridge. From that moment, it was necessary to start searching for partners who wanted to help us to achieve our goal. The initiative for the project was very well received and many companies wanted to contribute by sponsoring materials. We also looked for cooperation with other universities for technical and organizational input. Due to the size of the project it was clear from the beginning that we could not do everything by ourselves. Therefore, we immediately started looking for master students who could help us to elaborate the design of ‘Da Vinci’s Bridge in Ice’. In September 2015, a team of 10 students committed themselves to be responsible for certain parts or aspects of the building to be realized. To realize the fi nal construction of the ‘Da Vinci Bridge in Ice’ in Juuka, we needed more manpower than in the previous years. The building team consisted of about 180 people. In addition to the project members, several volunteers signed up for the project, including family, friends and fellow students from our university and other universities. The municipality of Juuka also contributed considerably to the success of the project. Although the bridge collapsed because of unusual weather, we have learned a lot and see it as a successful experiment. Without the help of the Juuka municipality and community, and the many volunteers, the project would not have been such a great success. By means of this booklet we want to thank everyone who was involved in the project. We hope that this booklet is a nice memento to the great achievement that we have received all together. Thank you very much for your eff orts and support! Happy readings, Roel Koekkoek, Thijs van de Nieuwenhof and Arno Pronk 11
