About TACK TACK Book How to Use What is Tacit Knowledge?
The different ‘places’ where one discusses or presents work, and the particular quality of the environment where these take place. These spatial metaphors range in character from being in-progress, pedagogical or informal to communicative, informational or archival.
The variety of media and formats in which research outputs can take shape, engaging different forms of communication, reaching particular audiences and accomplishing specific purposes.
The different ways in which one person ‘knows more than she can tell’ depending on the character and origin of the knowledge. These different forms of tacit knowing describe its specificity: pointing out whether something is implicit because it is unconscious, unrecognized, unsaid, uncodified etc.
The keywords, fields and concepts that situate the particular contributions of the network within broader literature and schools of thought.
The different phases and forms of dissemination that research and academic outputs can take, indicating the kind of publication, the progress of the work or the forum where they are presented.
The idioms that reflect the multinational character and vocalize the conversations of the TACK network and its outputs.
The members, contributors, facilitators, communities and organizations that build up, around and underneath the TACK Network and participate, in one way or another, in the endeavour of addressing the question of Tacit Knowledge in architecture.

Mouldy Smells and Tacit Noses: knowledges coming into view

© TACK
ABSTRACT
In 2016 two ‘moisture experts’ visited a small public building in Stockholm. Moisture had started to seep in, and mould started to grow in the wooden park building, the spores making the staff working there ill. The experts recorded the levels of microorganisms in the interior air and the composite building materials with scientific equipment and expert noses, identifying certain elements through technological data and odorous qualities. The expert noses registered the same smells as the staff in the buildings, but evaluated, analysed and categorised them according to their expert knowledge field.   Rather than aiming to make tacit knowledges explicit, this paper puts forward a methodological approach to tacit knowledge which unpacks and makes visible what tacit knowledges does, how it operates, and what and who it affects within architecture. By engaging with material ‘events’ (Bennett, 2010) and ‘stutters’ (Graham and Thrift, 2007), like this mould and its smell, through archival documents, scientific reports and changing building materials, the testimony of the material (Material Witness, Schuppli, 2020) makes visible the socio-economic and political value systems and decision-making processes embedded into the fabric of the building. It unpacks how things, otherwise hidden, come into view when systems, infrastructures and buildings break and fall apart, and how the various knowledge productions and value systems tied and embedded into this specific building and its mouldy materials can be unfolded and detangled through a theoretical framework of stutters, ruptures and events. Through this building, its smelly materials, and the different noses inside it, expert and non-expert, the paper unpacks how tacit knowledges operates, who or what can carry it, and what and who it affects.

No Body, Never Mind: The entanglement of how architects construct imagination

Figure 3.1: My Mother’s back, 1996, Elinor Carucci Source: Elinor Carucci’s private archive. US Credit: Elinor Carucci., © US Credit: Elinor Carucci
ABSTRACT
In architectural practice, one does not primarily write, one draws, models or explains with words, mostly through the visual communication of ideas. Just as architects use literacy to describe stories and connect with what touches them, material literacy is necessary to describe what architects literally touch. Material has the ability to respond to the design and even influence it at a very early stage of the process when it comes into contact with the body. As the scientist Barad rightly asked: “How did language come to be more trustworthy than matter?” (Barad, 2003). Material can create an experimental platform to trigger emotions, to go beyond norms and return to what has become schematic in the process of making architecture. This method of architectural dramaturgy, i.e., seeking a multifaceted narrative about house and home through engagement with material, could critically reveal unseen labour and unheard voices, and facilitate a connection to our surrounding.   The paper argues feelings from the inside of the body that apparent on the outside of the body offer new ways of knowledge production in architecture. Adopting the interdisciplinary approach by Finish architect and critic Juhani Pallasmaa (in his The Thinking Hand, 2009) the paper considers theatre and performance studies as examples of phenomenological aspects of kinaesthetic and multi-sensory perception of “the internal space and one’s inner mental space” (Pallasmaa, 2009, p.19). By theoretically analysing related emotions embedded in the various hands-on processes mediated through visuals (image, video, drawings) and the applicability of the materiality of the human body (voice, gesture, etc.), empathy and trust in both architectural and theatrical production are an important trajectory to enrich collective knowledge. Starting from here, the chapter advocates not only looking at visual mediation of material, but going beyond that and prompting the capability to read and listen to sound, expression and movement that come from both sides equally – humans and non-humans – to build up material literacy and achieve a sensitivity towards tacit knowledge in architecture.

POSTHUMANIST SANDBOX: THE POTENTIAL OF MULTIPLAYER – ENVIRONMENTS

ABSTRACT
This paper seeks to reveal a novel assessment of creative production in academic education, re-evaluating the conceptual and artistic potential of virtual real-time collaboration through digital media. Allowing for transcultural exchange as well as global participation, this could positively influence the development of novel artistic approaches and innovative measures for universities by contributing to a more contemporary, location-independent, and ultimately more equal form of art and knowledge production.

Pools, Carparks and Ball-Pits: Or why the Notre Dame restoration competition is a meme

ABSTRACT
The first restoration proposals to emerge after fire destroyed Notre Dame Cathedral’s roof and spire were jokes. The more serious schemes that followed Prime Minister Edouard Philippe’s announcement of a competition – many markedly similar, recreating what was lost in glass– were collected on mainstream design media websites like Dezeen where they attracted an unusually high volume of angry comments, accusing the architects of insensitivity. Soon after, Ulf Mejergren Architects’ proposal to replace Notre Dame’s roof with a meditative pool was edited into a carpark. It sparked a series of increasingly outlandish edits – first a multi-story carpark, then a ball pit – before the French Senate declared that there would be no competition after all. This at times absurd online interest might be new for architectural competitions, but it is easily explained through meme theory, as conceived of by scholars like Limor Shifman and Ryan Milner: systems of interconnected units of cultural exchange operating on both wider cultural and specific sub-cultural levels. In this essay I contend that meme theory can be used, in reverse, to analyse reactions to, and similarities between, even the most serious Notre Dame proposals. In applying this framework, we can begin to understand how competitions operate more broadly as part of a complex network online and how they relate to traditional competition conditions.

Book Corner: Canteiros da Utopia

The book Canteiros da Utopia, whose title can be translated as Construction Sites of Utopia, is the result of Silke Kapp's Post-doc research in Urban Sociology from the Bauhaus Universiteit Weimar, conducted between 2014 and 2015. Being Kapp’s supervisee during my Master’s studies in Architecture and Urbanism at the same university, which I had the pleasure to read still in its pre-printed version. Kapp’s ability to converge imaginative and critical thought is fully represented in this oeuvre, turning the experience of reading it one of both great literary joy and intellectual stimulus.

Building worlds: architecture as speculation on society

As part of The Persistence of Questioning, critical reflections for the future: ‘What is architecture?’, Lara Schrijver argues that Science fiction in particular can help architecture to consider unforeseen consequences of design decisions. We thoroughly need to recognize how on the one hand the environment and society are connected, and how on the other hand the future remains difficult to predict.

A Joint of Many Worlds: Entangled Stories in Battaile en Ibens’s 78+ Construction System in Timber

© Eric Crevels
ABSTRACT
This paper explores the distinct networks of technical and embodied knowledge present in the development of the 78+ construction system in timber, designed in the 1970-80s by Flemish design office Battaile Ibens. It develops the history of the knooppunt, a joint of a particular material and technical complexity that structures the system’s wooden beams and cross-shaped columns, and argues for the understanding of architecture and construction as complex constellations of different crafts and skills, including but not limited to architectural design and engineering. Design and technical decisions are traced in parallel to economic and marketing strategies, weaving together social and material phenomena that shaped the system’s history. From the initial designs and prototyping, through publicity decisions and appearances in international expositions, until its idealization in the office’s approach, the history of the knooppunt exemplifies the interplay between different stakeholders and knowledge orbiting the technological development of construction systems.

The object of this visit is a short novel, which has been later “translated” into a movie. The book is Lo stadio di Wimbledon by Daniele Del Giudice, while the movie is entitled Le stade de Wimbledon and it has been directed by Mathieu Amalric. Perhaps we could say that the visit has two objects, a book and a movie, or even, more precisely, that the real object of the inquiry at a certain point turned to be the intermediate operation of translation from the book to the movie. It is in fact in this gap or relation between the two, that it seemed possible to retrace a meaningful series of tacit reasons and of cultural connections, which were hiding behind the static singularity of the two considered in their autonomy.

Clay Landscape

This 1:1000 landscape model made from clay shows the site of a prominent 12th century church and graveyard located between two housing areas, Tensta and Rinkeby, built during the 1960´s as part of the Million Programme in Stockholm, where we are currently adding a wall of housing combined with an assembly hall, 100 metres long. In our practice we have used this kind of clay model for numerous projects over the years.

Book Corner: “Speaking of Buildings: Oral History in Architectural Research” by Janina Gosseye, Naomi Stead, Deborah Van der Plaat (2019)

© Janina Gosseye
This book is a collection of twelve essays by an international group of scholars which deals with various research methods of oral history and the question of who has been unheard. The book critiques that architectural history contains mostly the main architect’s view as well as addresses only a particular group of intellectuals. Therefore the individual narratives within an on-going relational process should be decentralized by having an 'integrative dialogue with actors'

TACK Summer School Report: Re-enacting Tacit Knowledge

During the 20th century, summer schools emerged as influential moments of encounter and collaboration between students and teachers from diverse cultural contexts. Yet despite their persistence and prominence, there has been relatively little exploration of their role in architectural culture and education. Re-enacting Tacit Knowledge, a summer school about the tacit dimension of summer schools held at Het Nieuwe Instituut in September 2021, set out to fill this gap. The event formed part of the ongoing collaboration between the institute and the Horizons 2020 Innovative Training Network: TACK / Communities of Tacit Knowledge: Architecture and its Ways of Knowing.

Coarse epistemes: Skill, craftsmanship and tacit knowledge in the grit of the world

© TACK
ABSTRACT
In the words of Dutch archaeologist Maikel Kuijpers, craft is “a way of exploring and understanding the material world”. This definition suggests that craftsmanship can be understood as a touchstone for a theory of knowledge in material productions. By exploring the role of skill in the processes of making and its epistemic correspondence, I develop the hypothesis that craftsmanship is as a perceptive-cognitive enactment within the making process, a form of attunement with production. The argument is that the material, productive side of work deploys and operates a particular epistemological regime, based on types of practical engagement deeply related to the possibilities and contingencies of objective, concrete reality. Making means implicating oneself with the material world, embedding the body in the processes of transforming matter and partaking in the flows of forces that form things. Thus, the knowledge in the making – skill – can be understood as the invention or establishment of a new mode of perception through action that is enacted by tools, movements, techniques etc. This practical perception acts as the foundational basis on which craftsmanship is performed, representing its conditions of possibility. Given the perceptual, embodied nature of craftsmanship, its transmission is rendered impossible outside the actual engagement with production. As such, this interpretation refers back to the original distinctions made by Gilbert Ryle of “knowing that” and “knowing how” that influenced Michael Polanyi in his definition of tacit knowledge. The particular epistemic rationality of crafts provides insights for understanding knowledge inside disciplines involved with creative practice, such as architecture. The epistemic coupling with production helps to understand how architects design, but it also reveals a general epistemic schism in the discipline, founded in the inconsistency between abstract designerly knowledge and the craftsmanship of construction.

Invisible Elastic Structure

Behaviour rather than form: nature as a worldview. Nature as technique, posture, and condition. A perpetual ongoing construction, nature is meant as an 'artifice' appearing in the encounter between thought and the world: both in the project and the leaf, a minimal resistant force, and a maximum space potential cohabit in a tensional condition. Architecture is a continuous experience of the world.

The Royal National Theatre from Architectural Review to TikTok

@whoresonlybathroom, ‘Brutalist architecture needs to die’, TikTok screenshot, 17 December 2019, © Hamish Lonergan
ABSTRACT
The Royal National Theatre in London (1976), designed by Denys Lasdun, has attracted an unusually high volume of critical debate. Tracing the ways that critics have disagreed over time, particularly on aesthetic grounds, reveals the fluctuating fortunes of concrete Brutalist architecture beyond the theatre. This cycle has continued to inform discussion online, on social media platforms including TikTok. Ultimately, this essay argues that the only way to make sense of these conflicting accounts is to value the theatre for its capacity to generate critical, aesthetic judgments.

Forêt DesCartes: Images, fragments, and repertoires in Kieckens’s tacit knowledge

ABSTRACT
Christian Kieckens' archive at the Flemish Architecture Institute in Antwerp holds a curious object: the Foret DesCartes. It is a prototype of Kaartenstander (postcards display table stand) designed by Kieckens in 1995. The object is extremely simple: an MDF board with maple veneer on which are inserted 16 postcard holders made of bent iron rods arranged in a regular 6x4 cm grid. More than just an odd display of postcards, this small object is an operational tool for producing and transmitting architectural knowledge through the collection of images and their recomposition in space. The same cognitive mode that is represented by the Foret DesCartes can be found reflected within Christian Kieckens' key practices: the architectural trip and its communication within a Belgian and European community of practice, the use of photography as a documentation tool but also as a visual reflection on architecture, the transmission of knowledge through the medium of the illustrated book and of the exhibition, the teaching of architecture by means of examples and references. Currently underway at the Bergische Universität Wuppertal within the framework of the TACK network, the research project, ‘The Pictures on the Wall. The Composite Culture of a Contemporary Flemish Architect’, investigates Kieckens’s role as mediator between the transatlantic architectural culture of the 1980s and the local context of Flanders. The key assumption is that this process of cultural migration happened first of all at the tacit level. Kieckens’s tacit knowledge is primarily found in its fragmentary nature – as a repertoire of themes and images – as well as in its crucial relationship with a number of visual practices and media. This attitude is considered from an interdisciplinary perspective that integrates external viewpoints such as those of cultural studies, anthropology, and iconology. On this basis, Kieckens’s practices have been operatively addressed by means of a hybrid methodology, which combines bibliographic and archival studies with a series of performative approaches such as interviews and immersive ethnographic investigation, pedagogical re-enactment and experimental display, images collection and visual comparison. Within a curatorial secondment at the Flanders Architecture Institute VAi in Antwerp and a collaboration with Hasselt University, these approaches finally resulted in the exhibition, ‘Forêt DesCartes – Christian Kieckens and the Composite Culture of Architecture in Flanders’, which opened at the De Singel Centre in November 2022.

Crackpot’ and ‘Dangerous’: On the authenticity of Miesian reproductions

© Ron Frazier from Bloomington IL, United States
ABSTRACT
In 2016, the architectural press reported the planned reconstruction of Mies van der Rohe’s Wolf House, built in 1927 in Gubin, Poland, and destroyed during World War Two. Supporters claimed that, by consulting the architect’s presentation drawings, they could rebuild the house authentically. They cited a simplistic reading of philosopher Nelson Goodman’s distinction between autographic art—where an original is certified by the hand of the author—and the allographic, which is replicated through notation. Barry Bergdoll called the proposal ‘crackpot’, arguing that without the lost construction documentation it would become a ‘simulacrum’: an allusion to Jean Baudrillard’s notion of a copy without reference. Mies himself thought there was something ‘dangerous’ in building ‘a model of a real house’ after constructing his own full-scale façade mock-up for the unbuilt Kröller-Müller House (1913). Since then, an unprecedented number of reproductions have entered into their own ‘dangerous’ conversation with Mies’ work, trading to varying degrees on their authenticity. Some, like the Barcelona Pavilion reconstruction (1986) engage with heritage and archival practices in an attempt to accurately reconstruct a lost work. Others, often appearing in exhibitions such as OMA’s La Casa Palestra at the 1985 Milan Triennale, exploit the fame of Mies’ architecture to offer a rhetorical interpretation that reinforces their own authorial signature. Meanwhile self-professed 1:1 models, like Robbrecht en Daem’s Mies 1:1 Golf Club Project (2013), seem deliberately tied to Mies’ authority, stripping away materials to focus on a singular reading of the work in a model-making tradition stretching back to Alberti. By returning to Goodman’s autographic/allographic dichotomy and Baudrillard’s simulacrum, this paper seeks to make sense of these multiplying reproductions across art, architecture and conservation, and their conflicting claims to authenticity. Ultimately, this frames Miesian reproductions as one contested site in broader discussions of architecture’s relationship to authorship and authentic heritage.
