Excursion to the MAN Steel House

On April 28 and 29, 2025, an interdisciplinary workshop on the topic of “measurement models” in engineering will take place at the Bauhaus-Universität Weimar. As part of the event, scientists from the fields of structural engineering history, civil engineering, design theory as well as monument preservation and restoration science will shed light on the historical context of model statics and discuss strategies for its preservation. All interested parties are cordially invited to attend.

Until the 1980s, the architecture of Soviet high modernism produced a large number of equally magnificent and unique buildings in various phases, often characterized by spectacular constructions. At the invitation of the National University of Building and Construction of Armenia, Werner Lorenz (coordinator, head of SP A2) and Christoph Dauberschmidt (head of SP B2) spent a week in Yerevan in February.

All interested parties are cordially invited to attend.

The second, expanded, edition of the SPP 2255 brochure was completed in March 2025 and arrived hot off the press at the coordination office in Cottbus today.

The Church of the Holy Guardian Angels in Schaffhausen, built in 1933/34, is an architectural jewel of its time. Built as a longitudinal truss church – with an invisible steel skeleton concealed beneath the masonry that supports the entire structure – it fascinates scientists. With the help of Anke Fissabre and Sebastian Hoyer from the sub-project “Hidden steel structures in sacred buildings”, the Saarbrücker Zeitung reported on the unique research project on the listed church on March 17, 2025.

Since 2021, the cluster workshops on questions of dealing with historic railroad bridges have become an integral part of the scientific exchange in the DFG Priority Program “Cultural Heritage Construction”. As in previous years, the 5th workshop of the Railway Bridge Cluster also aims to promote dialog between theory and practice; once again, it brings together SPP researchers and practitioners from Germany and Switzerland.

The 5th CommonGround 2025 in Bochum deals with the “dark sides of high modernism”. The term “high modernism” is the central connecting point of all sub-projects and is usually used to categorize the ingenious, far-reaching developments from around 1880 to 1970.
This year’s CommonGround paints a different picture away from the positive connotation and invites a reflective, critical examination of the negative consequences of the technological euphoria of high modernism.

In a world in which virtual realities increasingly dominate human perception, material and materiality are gaining new relevance than ever before. In the context of the annual meeting 2025, the fourth think tank of the DFG priority program Cultural Heritage Construction at the student center of the Bochum University of Applied Sciences Georg Agricola focused on the building material as the “basis of all construction” (J. Stark / B. Wicht).

The second funding phase of the SPP 2255 has begun.

New sub-projects are setting new accents, new formats of exchange have been added – including the first practical projects on the Wuppertal suspension railroad and the steel structures of Tempelhof Airport. The Cottbus team would like to thank all contributors, supporters and friends for their excellent cooperation and wishes you good health, good luck and many personal successes for the new year!

The first year of the DFG Priority Program 2255 Cultural Heritage Construction presented us with major challenges – but together we got off to a flying start. The coordination team would like to thank all contributors, partners and friends for their great commitment and diverse support!

We wish you all a Merry Christmas and good luck, health and many new successes for 2022.

How good it was to finally be able to exchange ideas in person again! Communication in the second year of our DFG Priority Program was characterized by a wide range of encounters, from common ground and cluster workshops to think tanks and annual meetings.

Thank you for your powerful commitment!

The Cottbus Head Office wishes all contributors, supporters and friends of SPP 2255 health, happiness, joy and success in their work in 2023!

The first funding phase of SPP 2255 is coming to an end, and we will be starting the second at the beginning of the year. Three more years of the Cultural Heritage Construction Research Network lie ahead of us. Some projects are coming to an end, others are being added. We would like to thank all those with whom we were able to work in the first phase for exciting encounters, multi-layered suggestions, valuable insights and their often inspiring commitment to the common cause – the interdisciplinary process of valorizing the cultural heritage of construction.

For 2024, Team Cottbus wishes both old and new contributors and supporters health, happiness and joy in their work!

Following the impulse meeting at the start of the second funding phase in May 2024, the SPP 2255 organized its fourth annual meeting in April 2025 in collaboration with the sub-project “Structural Health Monitoring of Iron Structures” (F2) based in Bochum and Dortmund.

The hangars built in 1933/34 on the former Cottbus-Nord airfield form a unique ensemble of extraordinary buildings of their time in Germany. With the help of Roland May, Thomas Klatt reported in the Lausitzer Rundschau and Märkische Oderzeitung newspapers on August 9 and 10, 2024 about this unique building heritage, which has already been the focus of several SPP 2255 events.

In the context of several workshops of the SPP 2255 at the Bauhaus-Universität, an exhibition presents the diverse fields of work of the nationwide sub-projects from the first funding phase (2021 – 23) of the priority program. Some historical components and material samples provide “tangible” insights into the subject matter.

The first workshop of Cluster H in the DFG Priority Program 2255 deals with two special manifestations of cultural heritage construction of high modernity – the inconspicuous and the invisible.

The aim of the annual “CommonGround” workshop for doctoral students and postdocs in SPP 2255 is to create common foundations – a CommonGround – with a view to the fields of the history of construction technology, engineering sciences and monument theory and to discuss these together. The fourth workshop in the series took place on October 14 and 15, 2024 in Weimar. The organizing team chose “High Modernism” as the common theme.

Since its caonstruction around 1900, the Vohwinkel carriage shed has been used for the storage, maintenance, servicing and repair of suspension railway carriages. Today, the operational requirements have changed dramatically; initial structural analyses also suggest fatigue problems with the supporting structure.

The former Berlin-Tempelhof Airport is one of the largest listed building complexes in Germany. Built between 1936 and 1941, the facility mirrors several phases of German history in a unique way. The huge building complex is also of particular importance in terms of construction history; back in 2011, it was already honored by the Federal Chamber of Engineers as a “Historical Landmark of the Art of Engineering”.

Listen now to the exciting podcast from the Berlin Chamber of Construction about hidden structures.

During the first funding phase (2021 – 2023), close cooperation had already been established between sub-projects A1 and A2 of the “Railway Cluster” in SPP 2255 and the Swiss Federal Railways (SBB) heritage conservation department. On the initiative of our Swiss colleagues, a new joint working group has now come together for the first time at ETH Zurich. It has set itself the goal of developing a position paper as the basis for a future ICOMOS charter on the preservation of railroad monuments.

The sub-projects A1 (Christina Krafczyk), C1 (Torsten Meyer) and C2 (Andreas Putz) jointly conceived and realized the workshop “Integrity of the cultural heritage of construction—Balancing of monuments of high modern construction heritage”, which took place on 21 and 22 November 2023 at the TU Munich. Starting point were two specific aspects of cultural heritage construction: its network structures (infrastructures, wide-ranging functional and personal networks) and its inevitable changeability (necessity of adaptation as continuously “functioning” parts of networks).

Night of Creative Minds invites you to explore the DFG Priority Program SPP2255 Cultural Heritage Construction or High Modernism via touch screen and 3D interactive technology.

The first three-year funding phase of the DFG Priority Program 2255 “Cultural Heritage Construction” (SPP 2255) ended at the end of 2023. In the context of the impulse meeting for the second funding phase 2024 – 2026, the SPP will present the fields of work of the eleven completed sub-projects from the first funding phase of SPP 2255 to a wider public in the foyer of the Central Main Building (ZHG) on the central campus of the BTU in Cottbus. In addition to general information, interesting objects and impressions from the respective activities in connection with the work will also be presented.

The second of the two three-year funding phases of SPP 2255 began at the start of 2024. In the first funding phase, eleven interdisciplinary sub-projects investigated different aspects of cultural heritage construction from 2021 to 2023 and exchanged views on its overarching aspects in numerous workshops. For the second funding phase, eight sub-projects were selected last year to continue their work in SPP 2255. Four of these build on topics from the first funding phase, while the other four sub-projects expand the spectrum and enrich the SPP 2255 with completely new research questions.

The history of building technology and the history of technology are sister disciplines. However, there is hardly any exchange. Scientific contacts, joint conferences or even projects are rare exceptions. There is an unmistakable difference in their research interests, topics and methods. But this is precisely where the potential of the encounter lies: the different emphases can also be seen as mutually enriching. There is much to learn from each other!

During the second annual meeting of the SPP 2255 in Dessau-Roßlau, the participants also visited on October 13, 2022 various historical constructions in the Dessau-Mitte industrial park in the course of a field trip prepared by Axel Schuhmann (Anhalt University of Applied Sciences). One of its preserved halls made a particular impression on the participants, yet there was hardly any information available about it – for example on the construction period or the planners responsible.

Subsequent research led to a surprising discovery: the building is a supposedly lost work by the architect and designer Peter Behrens (1868-1940), an exceptionally important figure for the development of modern architecture.

Just about a year ago, at the Sixth Annual Conference of the Gesellschaft für Bautechnikgeschichte in Berlin (11-13 May 2023), seven of the 17 presentations had been delivered by participants from the SPP 2255. This considerable presence in the German-speaking context of the history of construction was now followed by a no less remarkable international display at the 8th International Congress on Construction History in Zurich (8ICCH, 24 – 28.6.2024). This year’s conference with well over 200 participants from all over the world had been organized by the Institute for Preservation and Construction History at ETH Zurich.

On September 14, 2022, a compact workshop of the subprojects C2 and C4 took place in the rooms of the Custody of the TU Bergakademie Freiberg, where possibilities were exchanged on how the models investigated in SPP 2255 could be presented to the public in the form of a scientific exhibition.

The workshop deals with the current limits of 3D capture and digitalisation of particularly complex and filigree objects. The occasion is the challenge of digitalising a historical wire rope model for the Olympic roof landscape in Munich. This model exemplifies the difficulties and limitations of digital capture and representation. The cross-project exchange is intended to show new possibilities and approaches for the digitisation of these challenging objects.

A two-week exhibition in the architecture pavilion at the TU Braunschweig presents the fields of work of the eleven sub-projects of SPP 2255 to a wider public. In addition to general information, interesting objects and impressions from the respective activities within the framework of the work will also be presented.

The third annual meeting was already the last joint event of the DFG priority programme Cultural Heritage Construction in the first funding phase. Lectures, discussion panels and site visits provided ample opportunities to look beyond disciplinary boundaries. This time, the focus of the professional exchange was on the annual theme for 2023: “Upgrading the Highly Modern”.

On the Day of the Open Monument, the renovated GDR-type school gymnasium KT60L of the Freie Waldorfschule Magdeburg e.V. was opened to the public. During guided tours and the hands-on offer “Leonardo-Brücke-Bau”, the construction, the cultural value as well as the sustainability idea of the barrel-shaped supporting structure could be understood and discussed.

Im Rahmen von Gastaufenthalten bei den Teilprojekten B2 und B3 finden im Juni 2023 an der TU Dortmund Vorträge von Prof. Dr. Ir.‐Arch. Els Verstrynge (KU Leuven) und Prof. Dr.-Ing. Andrzej Cwirzen (Luleå University of Technology) statt, die auch online zugänglich sind.

The GDR produced highly typified load-bearing structures based on standardised building elements, which were in turn combined in type buildings. The workshop will focus on the phenomenon of state-led building typification in East Germany, with a consideration of West German type building for contextualisation. In addition to an insight into materials, constructions and development mechanisms, the constructive side of building in the GDR will be addressed and its worthiness of preservation discussed, away from the classical history of architecture and urban development.

The workshop will take place from 29.-31 3. 2023 at the Bauhaus University Weimar. A one-day excursion on 31. 3. will explore selected type buildings.

The third think tank of the DFG priority program cultural heritage construction is based on the annual theme 2023 of the SPP 2255 “High Modern Age adapt to the loads – cultural concepts and ingenious strategies for a difficult heritage”.

In high modernism, steel, along with reinforced concrete, was not only a building material whose material properties made it possible to realize architectural visions, structural innovations or infrastructural systems that had previously been considered impossible. In this context, the material was also connoted with a symbolism that made it an integral part of the contemporary promise of progress across all systems.

The Swiss Federal Railways (SBB) can look back on a long tradition of taking monument preservation concerns into account in planning practice. Firmly established structures such as the SBB Fachstelle für Denkmalpflege or the SBB Historic Foundation have proven to be very helpful. What can the railway and monument preservation in Germany learn from this?

The annual workshop Common Ground for doctoral candidates and postdocs in the SPP 2255 aims at creating common foundations – a common ground – with regard to the fields of history of building technology, engineering sciences and monument theory and to discuss them together.

When dealing with listed railway bridges in the Deutsche Bahn network, there is potential for conflict between the actors at many points in the planning process. Together with representatives of DB Netz AG and the preservation of monuments (VDL and NDL), concrete ways of acting together were discussed on November 11th, 2022 in the Lower Saxony Office for Monument Preservation in Hanover.

Participants from the projects Mass Phenomenon Commercial Hall (C3), Steel and Metal Lightweight Construction in the GDR (C4), Monument Spatial Framework (D1) and Reallabor Cottbus – Development of Construction Methods in the GDR (D2) met in the city of Erfurt on 27 July 2022 for the workshop “Halls with Steel Structures on Site – Erfurt”.      
Dipl.-Ing. Volker Mund, managing director and civil engineer of the engineering office Bauen GmbH, was available to the participants as an expert on dealing with GDR buildings and as a discussion partner.

The second annual meeting of the DFG priority program Cultural Heritage Construction once again opens up opportunities for intensive professional exchange and networking for the participants. Lectures, discussion rounds and on-site visits offer opportunities to look beyond the boundaries of one’s own disciplines, both with regard to one’s own project work and in relation to the annual theme of 2022 “Authenticity”.

The second think tank of the DFG focus program Cultural Heritage Construction addressed the concept of authenticity, a central value standard of monument preservation action, whose efficiency in dealing with the building constructions of the high-modern has hardly been examined up to now. Renowned experts traced the challenges, criteria and processes of concrete handling in this special area. On closer inspection, the ‘guiding star of monument preservation’ turned out to be a fragile and dynamic construction.

The “strategy and method laboratories” (SuMupLABs) are one of the central event formats to promote interdisciplinary exchange in the SPP 2255. They are explicitly aimed at the processors in the individual sub-projects of the SPP.
The SuMupLAB 2022 takes the participants to the former airfield Cottbus-Nord. The site, which was used by the military from 1933 to 2003, is currently undergoing forced expansion into a commercial location in the context of structural change in Lausitz. This raises crucial questions about the future authenticity of an ensemble of five aircraft hangars that are unique in Germany.

On November 25, 2022, a one-day workshop was held at the Technical University of Munich, which focused on an introduction to actor-network theory and the limits of its applicability in network research in the history of civil engineering. It was open to all SPP members and was jointly organized by the subprojects Plank Trusses (D2), Historic Concrete Repairs (B2) and Physical Models in Civil Engineering (C2).

Im Forschungsschwerpunkt SPP 2255 „Kulturerbe Konstruktion“ der DFG befassen sich WissenschaftlerInnen der TU BA Freiberg und TU Braunschweig mit den Konstruktionen des VEB Metalleichtbau-kombinat (MLK). Ein Typenbauwerk des MLKs ist das Sporthalle KT60L.
Die Sporthalle der Freie Waldorfschule Magdeburg e.V. wurde Mitte 1970er Jahre erbaut und in den Jahren 2007 sowie 2010/11 saniert. Sie stellt wegen des innovativen Erhaltungsansatzes ein Vorbild für den allgemeinen und auch denkmalpflegerischen Umgang von Typenbauwerken der DDR dar.

The annual Common Ground workshop for doctoral candidates and postdocs in the SPP 2255 aims to create common foundations – a common ground – with regard to the fields of history of building technology, engineering sciences and monument theory and to discuss them together. The second workshop of the series will take place on 11.10.2022 in Dessau and will deal with the monument values of constructions of high modernity relevant to the history of building technology.

Das erste Jahrestreffen des DFG-Schwerpunktprogramms Kulturerbe Konstruktion eröffnet den Mitwirkenden aus den verschiedenen Teilprojekten die Einblicknahme in verwandte Fragestellungen und Untersuchungsmethoden sowie Möglichkeiten zum intensiven fachlichen Austausch und zur Vernetzung. Vorträge, Diskussionsrunden und Vor-Ort-Besichtigungen bieten Gelegenheiten zum Blick über die Grenzen der eigenen Disziplinen sowohl im Hinblick auf die eigene Projektbearbeitung.

The DFG priority program “Cultural Heritage Construction” (SPP 2255), coordinated by the BTU Cottbus-Senftenberg, has been operating for a year. Despite all the current adversities, the network of 19 research institutions in Germany and Austria, financed with €2.5 million per year, set standards in the first year.

The colloquium will report on ongoing research projects on concrete restoration. The focus will be on issues relating to the preservation of historical monuments.

On September 09, 2021, the Institute of Building Preservation and Structure and the Institute of Steel Construction at TU Braunschweig invited Cluster C to a one-day workshop. All subprojects, Innovation system of the steel industry (C1), Physical models in civil engineering (C2), Mass Monument Industrial Hall (C3) and lightweight steel and metal structures in the GDR (C4), were represented. In additionAntonia Zöllner M.Sc. participated with her associated project Above-Ground Structures of the Rammelsberg.

The Sternbrücke in Hamburg-Altona is not only a fascinating example of ultra-modern bridge construction from the 1920s. It is also one of the most prominent railroad bridges in Germany, the replacement or preservation of which has been the subject of intense debate on both sides for years.

On October 22, 2021, the Institute of Solid Structures of TU Dresden hosted a hybrid workshop on the topic of dealing with historic railroad bridges. The workshop, which was held with the participation of invited guests on site in Dresden and in the form of a parallel online conference, was aimed at the participants of the thematic cluster A (railroad bridges) of SPP 2255, which is composed of the two subprojects „Monuments in the Network “ (A1) and „Holistic Evaluation of Steel Railway Bridges“ (A2).

The aim of our event is to create a common knowledge base for the work and understanding in the interdisciplinary structured SPP 2255.
Common Ground #1 had as its theme a theoretical and application-oriented consideration of the concept of the history of building technology.
The event took place in Cottbus on 11.12.20121 – and thus on the day after the think tank (Building at the Limit) – so that all the research associates could participate in both events in presence.

In Weimar, the members of the subprojects DENKRAUM (D1) and Brett- und Bohlenbinder (D2), which are connected in the cluster D, met for a two-day workshop at the Bauhaus University. In lectures and discussions common questions and topics of the two subprojects were worked out, especially with regard to the current SPP annual topic Building at the Limit. In addition, excursions to interesting roof structures of high modernism in Weimar and the surrounding area were undertaken.

Die „Strategie- und Methodenlabore“ (SuMupLABs) sind eines der zentralen Veranstaltungsformate zur Förderung des interdisziplinären Austauschs im SPP 2255. Sie richten sich explizit an den Bearbeiterinnen und Bearbeiter in den einzelnen Teilprojekten des SPP.
Das erste SuMupLAB 2021 führte die Teilnehmerinnen und Teilnehmer in die ehem. Sendehalle von Radio Europe 1 im Saarland. Das 1954/55 errichtete Bauwerk steht exemplarisch für das erste Jahresthema des SPP 2255 – „Bauen am Limit“. Der lichtdurchflutete Bau wird von einer gut 80 m weit frei spannenden Hängeschale überdacht, in deren spannungsreicher Baugeschichte die Grenzen des technisch Beherrschbaren in dramatischer Weise offenbar wurden.

In lectures and interdisciplinary discussions, the first think tank of the priority program Cultural Heritage Construction addressed two apparently almost opposite facets of ultra-modern construction, which were put up for discussion with the annual theme 2021 “Building at the Limit”: exploring structural limits at the limit of what was previously conceivable while minimizing the use of materials on the one hand and the confinement of structural thinking in codified limits of what is permissible by a previously unthinkable regulatory apparatus on the other.

The aim of our event is to create a common knowledge base for the work and understanding in the interdisciplinary structured SPP 2255.
Common Ground #1 had as its theme a theoretical and application-oriented consideration of the concept of the history of building technology.
The event took place in Cottbus on 12.11.2021 – and thus on the day after the Thinking Workshop (Building at the Limit) – so that all the research associates could participate in both events in presence.
