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.

On Twists and Turns. Architecture: Design and Judgment

Herman Hertzberger, Sketch Ministerie van Sociale Zaken en Werkgelegenheid, The Hague, The Netherlands, August 1984
ABSTRACT
Architects design in different ways, but rarely in the form of waiting for a singular hunch. Most often, instead, designing is hard work, reassessing material again and again, until the moment the various facets come together convincingly. In this paper, I use Hannah Arendt’s discussion of judgment in order to understand the process of design. Arendt borrows her understanding from Immanuel Kant, but draws it out of his aesthetic perspective and reassesses it into a political context. She emphasizes how a community is a necessary prerequisite for every judgment made. It is not enough to simply hear what others say, but one need to be able to think from that particular situation, in order to judge the validity of that perspective. I see a parallel here with design, though architects operate in different communities. The main challenge of design then is to connect these communities through the design and to understand what kind of information and knowledge can be gained within the different communities. By drawing the parallel, I will discuss the different knowledge communities wherein architects operate, and how 'judgment' offers a model of activating various knowledge systems.

Explicitly Tacit: Polanyi’s “Tacit Knowledge” in the Architectural Theory of Charney and Rowe

ABSTRACT
The scientist and philosopher Michael Polanyi coined the term “tacit knowledge” in 1958 to describe a type of unconscious, embodied and social knowledge that could not be explicitly taught through rules or rote-learning. He argued, instead, that some knowledge relied on practice, critique, socialisation and personal biography. In this sense, something like tacit knowledge has long played an important role in architectural education — where skill is acquired through (re)drawing, writing and model-making, reviewed by teachers and peers — even before Polanyi named it. Yet, for all the affinities between design education and tacit knowledge, Polanyi’s epistemology has rarely been directly addressed in architectural theory. This paper considers two exceptions in the writing and pedagogy of Melvin Charney and Colin Rowe in the 1970s. Both figures used Polanyi’s philosophy to propose alternatives to the “ultra” positions of Modernism. Charney argued that Quebecois vernacular architecture reflected a tacit, collective building culture that was inseparable from the embodied construction practices of craftspeople. This could not be made explicit in construction manuals or histories; students had to discover it through drawing and building themselves. Meanwhile, Rowe credited Polanyi’s Beyond Nihilism (1960) in the gestation of Collage City (1978, with Fred Koetter). Polanyi’s essay argued that individual freedom was important in making new discoveries, but that individuals still had a responsibility to go beyond themselves by conforming to collective norms and standards. This, too, found a parallel in Rowe and Koetter’s rejection of Modernist utopianism. At the same time, a close reading of these minor encounters reveals certain continuities and misalignments between Rowe and Charney’s interpretation and Polanyi’s own position as a prominent anti-Communist and contributor to early neoliberalism. Ultimately, this paper aims to clarify the role of tacit knowledge in the theory of these two architect/educators and, in doing so, simultaneously clarify the relationship between tacit knowledge and architectural pedagogy more broadly.

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.

Revealing the tacit: a critical spatial practice based on walking and re/presenting

ABSTRACT
Spatial practices that investigate architectural space with the ideal architect's eye and a commonplace representational perspective have been the subject of a lot of writing. The potential of critical spatial practices, which combine performative actions with incomplete representation possibilities, to investigate and reveal the tacit knowledge underlying space is yet unexplored. This paper finds its problem in these missing pieces in the literature and tries to decipher by deconstructing the conventional methods and tactics it criticizes, a way is sought to trigger the creative potentials of the relationship between body and space that cannot be stable. Critical spatial practices can be situated as alternative ways of understanding the architectural space and establishing a dialogue with it since they pave the way for new kinds of relationships to emerge between the subject and the space. This study focuses on the act of walking, which is claimed to be a critical spatial practice, and its re/presentation, which is argued to reveal tacit knowledge in the walked place. Based on the poststructuralist critical theories, the case study was carried out in the Historical Peninsula of Istanbul in the Khans District by walking and extracting the things which can reveal tacit knowledge. By finding top-down investigation and representation tools problematic in capturing and expressing the body and space interactions, experiences, and experimentation on the ground level, I believe walking by drifting through the invisible spaces and transitions of the Khans District when viewed from above is meaningful in expressing the experimental and creative flows on the ground level. Depending on the re/presentation, it can be suggested that performing a spatial practice with the participation of the body and interpreting the architectural space from a critical position carry the contingency of uncovering tacit knowledge.

We understand the city as a forest: a complex (eco)system in which various spatial elements are synergistically and dynamically networked. In this sense, with every design, the challenge and the opportunity arise to contribute to the system as a whole rather than creating a solitary object.

Busy body – Living and working in urban renewal neighbourhoods 

Littie Diederen and Yvonne van den Elsen, Zoiets Maak Je Toch Niet, Ik Zeg Altijd, Dat Doen Mannen... Ervaringen van Vrouwen in de Stadsvernieuwing (Amsterdam: NCDB, 1983).
ABSTRACT
Urban renewal reinforces the isolation of working-class women. This was concluded in the 1983 publication “Zoiets maak je toch niet, ik zeg altijd, dat doen mannen…”. This booklet criticizes 1980s participatory urban renewal of the Staatsliedenbuurt in Amsterdam and addresses the exclusion of women. Several inventive tools were developed in this neighbourhood to empower women to make their diverse, tacit, embodied knowledge heard and make design suggestions that better fitted their needs. As a result, new knowledge was brought into participatory urban renewal processes of which women were so often excluded; diversifying and expanding what was commonly perceived as the concerns of the resident. This paper brings forward various tools developed in the Staatsliedenbuurt that were used as vehicles to bring women’s voices into urban renewal processes, such as the fictiocritical character Els, a workshop on dwelling stories, and a manual. The paper contributes to histories on the collective efforts by various women’s groups in the 1980s that fought exclusion and sought to develop feminist approaches for urban design by making what is the tacitly known, explicit; making the invisible, visible.

This precast concrete column fragment from the Pirelli Learning Centre built in Milan (Italy) in 2022 is a case in point. The physicality of the column has created a strong reference to the between-war Italian architecture culture. Its material form speaks to the innovation in construction techniques that characterised the period, while its ornamentation echoes that of the neighbouring Bicocca degli Arcimboldi villa; illuminates the company’s history as well as the common culture through a series of abstract tire thread advertising graphics imprinted on the columns and façade elements.

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.

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.

Rooms: Architectural Model-Making as Ethnographic Research

Fig. 1
ABSTRACT
Within design and architecture, scale models can create worlds of proposition, speculation and fiction. This paper situates the model as a tool for observation, documentation and engagement; a slow, durational method that manifests a deep participation in the lives of place and people marginalised by wider society. Rooms was an artistic and research project undertaken as part of the Urban Nation artistic residency in Berlin which looked at the Romanian immigrant community inhabiting the city, the spaces they occupy and appropriate, and the objects that they surround themselves with. These instances were drawn, surveyed, documented and then recreated through 1:20 paper models. Built to an extreme level of detail the models of everyday space visualise, offer new insight, and give a sense of value and recognition to the lived realities of individuals. A situated mode of research, this form of representation transforms the seemingly mundane into an object of beauty and atmosphere, encouraging access and participation from the participant, maker and the viewer. The inherently collaborative aspect of this process reveals the tacit, implicit knowledge present in everyday actions.

Latent Continuities: Architectural knowledge and the heuristic tension of Indwelling

ABSTRACT
In his theory of Tacit Knowledge Michael Polanyi introduced the concept of Indwelling, to explain the role of habit and skill in practice-based knowledge, but also to describe a heuristic tension that underlies all forms of knowing. Such a tension, Polanyi tells us, unfolds from the ‘depths’ of our biological being to the ‘heights’ of ideas and cultural values. The premise of this essay is that the spatial (and temporal) metaphor of Indwelling is hardly an accident: human consciousness is opened to knowledge primarily through our physical engagement with the world, marked by both space and time. The hypothesis is thus formed of architecture as a discipline studying precisely such tacit processes of (In)dwelling, in search of correspondences between ‘thick’ levels of bodily disposition and ‘thinner’ levels of intellect and imagination. To pursue this hypothesis, I turn to the example of a two-month apprenticeship in traditional stonemasonry, that took place in 2019 in Greece, entailing the reconstruction of a particular type of dry-stone cobbled pathway, called kalderimi.

‘Objects of belonging’ are found or ready-made objects that users adapt to redefine the conventional boundaries of a home. These objects’ tacit presence dissolves where the house begins and ends, blurring boundaries between urban and domestic spheres.

Clay 3D Print of Urmein

The model displayed here, a Clay 3D Print of Urmein, a rural village in Switzerland, highlights the exploratory path that architects often take when new technologies become available. The model is based on information drawn from photogrammetry and drone footage, and has been produced by a clay printer intended for pottery – all tools that do not typically belong in the architect’s toolbox.

Book Corner: ‘Pre-Positions’, in Site-Writing: The Architecture of Art Criticism by Jane Rendell (2010)

Rendell, J. (2010) ‘Pre-Positions’, in Site-Writing: The Architecture of Art Criticism
The introduction to the author’s positional body of work, sets the theoretical and intellectual context for the ideas underpinning Site-Writing as a practice and their aims in giving voice to this form of practice. The author uses seminal writers on phycology, art-practice and philosophy as figures to guide their later theories and discusses the relationship between architecture and art-critique as reflective and positional practices.

Texture Kortrijk – Jewel Box

Wooden model (1/400), representing an existing warehouse and its extension. The orthogonal cast-iron column structure of the existing building is continued in the lightweight steel building on top. The new beams connect the column grid diagonally and at two different heights. The result of logic structural thinking is an unexpected golden crown. The museum Texture celebrates the prosperous past of the flax industry in the region, that used to give the river Schelde a golden shine.

RE-enactment

In 2015 we exhibited our work in this gallery and made some spatial interventions, including coloured columns, such as this one. These interventions represented our way of thinking, reflecting, acting, and communicating. We believe that a RE-enactment of a part of this exhibition fits well within the TACK framework. We thus proposed to RE-instal a column.

The chozos are traditional huts that up until about 50 years ago were built by shepherds in rural Spain as they moved around the fields with their sheep. This chozo was constructed in September 2022 by sixteen students from the University of Stuttgart during an intense exchange with experts in southern Spain.

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.

Urban Predation: The symbolic economy of the Pixo

Image 02: Denilson Baniwa Yawareté Mural Artist: Denilson Baniwa Photo: Rafaela Campos Alves , © Creative Commons
ABSTRACT
This essay proposes an analysis using the “symbolic economy of predation” to provide new perspectives on the question of pixo. For this, pixo will be considered as any act on walls, building facades, asphalt or monuments rejecting the hierarchical separations between writing, scribbling, painting or graffiti imposed by the art system and other institutions. In Amerindian ontology, as Viveiros de Castro describes, the feeding regime is the predominant model upon which relations are perceived. The predator and prey duality stands as the archetypical role ruling interactions between different subjectivities and perspectives. This “symbolic economy” permeates social relations and translates them into a particular epistemology shared by many indigenous peoples throughout the Amazon region. We aim to consider the relationships between those who practice pixo and the city through an analogy with the predator and prey dialectic. We argue that, on the one hand, these taggers get symbolical dominion over the city’s territory by marking places with their signatures, thus gaining recognition from their peers; on the other, the city - represented by formal governmental and economic institutions - preys upon taggers by criminalizing their practice as vandalism and by socioeconomically excluding peripheral populations, thus denying their access and right to the city itself. Pixo is a reaction to the passive role imposed on society that gains critical and artistic qualities as a practice of protest, endorsing its predatory performance. This analogy intents provide a new perspective to describe the city and its complex relations with the aesthetical and social realities of its inhabitants. A distinct description of the urban relations that might enable planners and policymakers to evaluate socio-political phenomena within the city through a new set of lenses, allowing the development of innovative approaches to tackle and decriminalize conflictual practices as the pixo.
