Digitization is one of the buzzwords of the 21st century. Also in restoration, conservation and the preservation of cultural assets. Our author Boris Frohberg attended a conference of the Association of Conservators in Dresden and provides information on the possibilities offered by digitization processes in the preservation of cultural assets

The interdisciplinary collaboration between restorers, archaeologists, engineers, architects and process engineers offers a wide range of possibilities.
The VDR conference from March 1 to 3, 2018 at the Dresden University of Fine Arts brought together around 120 scientists and conservators to listen to the twenty presentations.

The topics of the four blocks ranged from the basics of the technology to its practical application. The lectures covered a wide range of materials used in restoration, e.g. wood, metal, stone, wax and wall paintings – from the Middle Ages to the end of the 20th century.

A thematic introduction to 3D techniques by Christian Mulsow, Patrick Lackner and Tobias Reich was followed by practical examples of 3D scanning methods, the “Structure from Motion” method, inventory and damage recording, surveying in the context of photogrammetry, 3D monitoring and 3D documentation. It is important to clarify in advance what you want to do with the virtual three-dimensional model and which questions need to be answered. This results in the search for the appropriate technology for implementation and cost calculation.

The laser scan for the practical application of the technology for visualization and reconstruction can be conveyed very clearly. New worlds can be opened up for museum visitors and younger groups of visitors can be interested. This also applies to wet wood finds from medieval mining in the Ore Mountains and the Bremen cog. The impressive size of the objects alone convinced the participants of the technological possibilities. The recording of ancient, medieval and modern sculptures can also be very useful for virtual reconstruction, but also for comparative research.

The accuracy of fit of fracture edges after scanning is unrivaled by the possibilities offered by craftsmanship. The compatibility of the printed materials in relation to the original can certainly be assessed positively. The example of the “Luke from the Ashes” from Munich’s Theatine Church demonstrates the combination of digital technologies and traditional sculpture. The partial reconstruction could be tested beforehand on the 3D model. This also applied to the reconstruction of rock formations in the Neptune Grotto in Potsdam. Here, scale models could be printed in order to test the correct structure of the natural stones as a template for the reconstruction of the original artificial rock formation.

The costs of using the technology are still very high and are therefore limited to a few pilot projects, most of which are externally funded. In addition, the data volumes usually still present processing problems due to computer performance. This means that evaluation and storage are only possible to a limited extent. On the one hand, devices built from components that can be ordered can be an inexpensive solution. On the other hand, the performance capabilities of computers will continue to increase and the processing of data volumes will appear simpler. Nevertheless, the problem of data storage over longer periods of time remains. Whether the monitoring projects will still be available in a few decades’ time and usable for the desired increase in knowledge is desirable.

The conference began with a one-day workshop on the Structure from Motion method, hand scanners and 3D mapping and 3D reconstruction. Alexander Gatzsche, Kerstin Riße and Thomas Hackbeil explained the Structure from Motion method and the use of handheld scanners. Gunnar Siedler explained the possibilities of 3D mapping with Metigo Map to the participants.

Conclusion

The organizers and participants agreed that 3D technology offers many previously unknown possibilities. The questions of how far one should go when using scanning methods and when the technology will take on a life of its own were certainly discussed here. The opportunities and possibilities that this technology can offer and where the limits lie in dealing with virtual copies were explored. It remains to be seen whether this technology will also become increasingly established in restoration.

Viva la Piazza Zenetti

Building design
General

Since summer 2018, Piazza Zenetti in Munich has been an example of how a former parking lot can make neighbourly coexistence possible in a large city. Nevertheless, the planners responsible at raumzeug have to defend their project time and again.

Since summer 2018, Piazza Zenetti in Munich has been an example of how a rethought parking lot can make neighbourly coexistence possible in a large city. Nevertheless, the planners responsible at raumzeug have to defend their project time and again. G+L editor Theresa Ramisch presents the project here.

I always thought that the housing situation in Munich depended on how much money you had. But it’s actually a question of luck. At least if you believe the people of Munich. If you ask them where they live in the state capital, the classic answer is: “I was lucky.” Only after a meaningful pause is it revealed where the actual place of residence is. This is usually somewhere within or on the edge of the Mittlerer Ring. Well, or even in Großhadern. Happiness is subjective.
Yes, it takes a lot to find a suitable apartment in Munich. Money alone doesn’t always get you there. The pressure on space is enormous. So it’s no wonder that the financially weak creative scene in the Bavarian capital has little space left – for living and working. But also to initiate new projects. And this despite the fact that it offers so much potential for long-term urban development, as we discuss in the October 2019 issue of G+L.

But despite all these adversities, Munich’s creatives have managed to fight for a small inner-city area where creative bottom-up processes are once again possible. The Munich Schlachthofviertel. Here, players such as the Wanda e.V. association with Alte Utting or Bahnwärter Thiel are proving how creative projects can make a city like Munich – which is already considered to be highly liveable – even more attractive. What is special about the Schlachthofviertel, however, is that the Munich planning department is also jumping on the creative bandwagon that is currently thundering through the district. With the Piazza Zenetti.

Zenettiplatz led a dreary existence until the summer of 2018. There was no quality of stay here. Parking spaces defined the square. Nobody wanted to sit down and stay. But then, as part of the “City2share” project, the city invited tenders for the design of Zenettiplatz as a mobility station including a temporary neighborhood meeting place. The Munich office raumzeug was awarded the project and landscape architects Johann-Christian Hannemann and Felix Lüdicke developed a two-part square design, which is now – with further additions – in its second year.

The design

The southern area accommodates a wide range of mobility options with car-sharing parking spaces, e-charging stations and public transport bikes. The planners developed the northern area, which is part of the recreation and communication area, together with the residents in a needs analysis and a design concept. The result is a multifunctional, colorful square that is well received by the neighborhood.
An all-round, colorful piece of furniture – built as part of a participatory construction site – defines the spatial design. It encompasses the square and continues on the other side of the street, combining mobility with a place to stay. Six raised beds, a collection of potted plants and several rambling trees are responsible for the greenery on the otherwise very gray square.
In summer 2019, a carpet of grass was also added, which was only supposed to be here for two weeks. However, three dedicated neighborhood children campaigned to extend the lawn experiment over the entire summer – and beyond. The lawn is currently spending the winter at the neighbor’s, the Thiel railroad yard.

The use

The planners’ aim was to ensure that the square could be used for a variety of purposes. And they have achieved this. The surrounding (currently green) furniture can be used for sitting, working, but also for running around and playing. There is an information board, which acts as a bulletin board and reports on current activities in the piazza, as well as a book exchange shelf, a deposit niche, a swap board and lockable boxes for toys and tools. Simple, robust and functional – this triad best describes the character of the Piazza.

But wouldn’t parking spaces make more sense?

The planners actively involve the neighborhood with joint activities. One such campaign was the fountain experiment that took place in Piazza Zenetti in mid-July 2019. If you look at the pictures, it looks fun, doesn’t it? And it was. The sad thing is that not everyone is convinced by the fun. Even after two years – even shortly after such a successful event – Johann-Christian Hannemann and Felix Lüdicke in Isarvorstadt are still discussing whether the space is being used at all and whether ten parking spaces wouldn’t make more sense. The planners from raumzeug repeatedly hear “gentrification” criticism at the square: that they are only staging the functioning of the piazza and that the neighbors don’t use the square at all.
Are the critics right? My opinion: No. Firstly, a hundred meters further on, behind the underpass on Tumblingerstrasse, there are always free parking spaces. You just have to use them. Secondly, we should all be driving less anyway. Thirdly, the raised beds are blooming and growing. Why is that an argument? They are looked after by some extremely dedicated space and bed sponsors from the neighborhood. Doesn’t that alone speak for the fact that the community in Piazza Zenetti works? I mean, apart from the fact that there’s always someone sitting here? … Exactly. And fourthly: I’ve rarely been to a place in Munich where neighborly togetherness comes about as easily as in Piazza Zenetti. We don’t need to discuss the fact that neighborly togetherness is rare in a big city like Munich and is becoming increasingly rare. Nor do we need to discuss the fact that we need spaces without consumer pressure that bring us closer together as people, as neighbors, that counteract the increasing anonymity in the big city and that activate togetherness instead of coexistence. Public spaces should invite, not exclude. And that is precisely what the Piazza does. Thanks to the spatial design by Johann-Christian Hannemann and Felix Lüdicke, but also thanks to the social commitment of the planners themselves. They can be found in the Piazza every Wednesday from 6 p.m. for the neighborhood meeting “putz, plausch und plan”. And they don’t even live in the neighborhood. That’s what I call commitment.
