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.

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.

For architects, hand drawing is not only an important tool to grasp the history, experience, and knowledge of a place but also a space of tacit negotiation with peers and others. After the 2011 Tōhoku earthquake struck Japan, Atelier Bow-Wow began to produce collective hand drawings on large paper sheets, on which several work simultaneously, to jointly find a better future. This approach was further developed with students in different public spaces.

In Quest of Meaning – Revisiting the discourse around “non-pedigreed” architecture.

ABSTRACT
In their practice, architects never refer to something as “pedigreed” to describe their work. However, during the 1960s, Bernard Rudofsky introduced the term "non-pedigreed" architecture, which he attributed to edifices not designed by formally trained architects, but for various reasons, their status exceeds that of the "mere building". As a fact, since explicit knowledge around “non-pedigreed” architecture is scarce, architects rely mostly on interpretations. This contribution revisits several of these interpretations through the perspective of its "actors," referring to the scholarly work of selected architects, and it is structured into three parts. The first section introduces the motivations behind the study of "non-pedigreed" architecture, delving into questions of aesthetics and authorship. The second part explores the fruitful contradictions arising from the first section and focuses on the relationship between vernacular architecture and the concept of Time, as well as the development of craft skills. Finally, the third part examines specific case studies where the value of vernacular architecture shifts from being merely a reference point to becoming an integral part of the architectural production process.

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.

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

By GodefroyParis - Own work, CC BY-SA 4.0, https://commons.wikimedia.org/w/index.php?curid=78090147, © By GodefroyParis - Own work, CC BY-SA 4.0, https://commons.wikimedia.org/w/index.php?curid=78090147
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.

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.

A Post-Post Positional Praxis: Locating ideas of repair in a Southern city

© TACK
ABSTRACT
Abstract The legally implemented South African Apartheid city model of the 20th Century very specifically separated urban inhabitants along strict racial spatial definitions as set out by city practitioners and mandated by the national government on top of the existing colonial state model of segregation. These societal logics and legal systems have had a wide-scale systemic phyco-spatial effect on the many generations of urban dwellers who have no reference to patterns of living and space-making outside of this city-model. More specifically, the laws and regulations that carried these ideologies have instilled largely prejudiced tacit forms of understanding of self and ‘other’ that remain deeply entrenched in the spatial practitioners who are trusted to design and make within this context. For this reason, a critically proactive engagement with these harmfully biased tacit knowledge systems is a crucial endeavour across the built-environment practice – especially so in the architectural and the related spatial design disciplines. Such a deeply interpersonal recognition of such dynamics within spatial-design practice call for approaches, methods, and techniques that operate through considered and inclusive forms of practice that are often difficult to frame within the current ‘northern’ framings of the architect or the designer. Instead, other conceptual frameworks such as Southern Urbanism offer a more situated armature to locate these questions and begin an other-wisely based inquiry through these challenges. By thinking about an architectural - or more appropriately: a spatial design practice - through values and actions that are true to the locus of the site from which they exist, on the situated terms of the context that produce them, and through the languages – spoken, gestured and visual – that they are actioned through; the research holds an the potential to reveal other forms of more connective tacit knowledge that exist in these ways of making and maintaining urban spaces. Such an inquiry holds the potential to guide these practices both within the disciplines of the architect and support those engaging with these dynamics to expand their understandings of practice and the ‘Imaginative Geographies’ of separation and difference that continue to shape the post-Apartheid and post-Colonial cities of South Africa.

(Un)Programming the Factory: Weaving Panopticon Stories

ABSTRACT
This paper departs from practice-based research developed in Coelima, a Portuguese textile factory under socio-spatial dismantlement, to investigate the relationships between its assembly line, stories, and weaving. I ask how sets of tacit knowledge developed through workers' stories and temporal hand-weaving practices can provide new directions for architectural design to reimagine alternative 'poethical' (Retallack, 2003) working modes in the assembly line. To do so, I build upon workers' stories, which refer to acts of surveillance experienced in the weaving department under capital efficiency (Giedion, 1948), to investigate the tacit process of patterning stories through weaving (Kruger, 2001; Albers, 1959). Words taken from the workers' stories are designed as weave draft notations, or 'panopticon patterns', through a collaborative event with a group of former workers of Coelima to generate a site-specific textile language and knowledge. Although this knowledge can only be transmitted via experience, repetition, and performative making (Nimkulrat, 2012), I suggest that it can evoke emancipatory possibilities for workers and architects to reimagine socially and spatially other configurations for the assembly line grounded in ideas of industrial commons (Rappaport, 2021). Finally, I argue that knowledge acquired from weaving, weave draft notations and stories can provide creative means for architectural design to (un)program work control and time in Coelima's assembly line while re-evaluating issues of (post)work, pleasure, and productivity within the contemporary workplace.

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.

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.

Aspectos da conceituação do trabalho em Marx: a alienação como abstração concreta

ABSTRACT
This article covers a question relative to the double determination and dialecticity in the concept of labour, as developed by Marx from the Hegelian dialectics. It seeks to demonstrate the ontological significance of the concept to the Marxian thought, a key element in his critics as a path to self-conscience and as a territory for alienation. Through the inquiry on the concepts of abstraction concreteness in relation to labour, it hopes to clarify its employment and epistemological reach as it provides an understanding of alienation as a process of abstraction that, projected in the social relations of production, becomes concrete.

At the last CIAM conference held in Otterlo in 1959, members of Team 10, including Alison and Peter Smithson, Aldo van Eyck, Daniel van Ginkel, Blanche Lemco, and John Voelcker, enacted an ironic funeral procession, presumably carrying CIAM to its grave. It was captured on film by Jaap Bakema. After the demise of CIAM, Bakema initiated a newsletter to keep the network updated. Between 1959 and 1981 he compiled 18 such newsletters, which comprised a summary of contributions he received from around the world.

Decoding a Practice’s DNA: Multiple registers of tacit knowledge

ABSTRACT
In the manifold spectrum of how tacit knowledge can be conceived in architecture, the contribution aims to investigate that embedded in the architects' design process by reflecting on the codes they employ.   If the vectors are tools or communicative materials –i.e., drawings, sketches, models, texts, etc.– used for transmission, the codes are here interpreted as those characters –whether in the form of recurring patterns or aesthetic choices, technical solutions, vocabulary, etc.– that define the specificity of a practice. As the DNA of an office, and not just of its principal, as Rem Koolhaas argues (Winston, 2016), they articulate across different levels depending on the context within which they are shared: spanning from the ones used within the practice itself –forming the basis for collaboration between different project team members;– to those adopted externally to communicate with both clients and an extended community of practice. Differences in terms of codes might parallel diverse methods for their investigation. Indeed, for the former, the use of an ethnographic approach capable of unpacking specificities from within seems to be the most adequate –i.e., revealing how the implicit values of a practice are transferred into form through a collective process mediated by multiple actors;– for the latter, instead, it would be more proper to employ public occasions as a pretext through which to decipher a shared “language.” (Eco, 1976).   In general, the paper argues that codification processes are necessarily conditioned by the context in which they take place, by the positioning within the disciplinary debate, and by the actors (Latour and Yaneva. 2008) participating in their development. These closely interrelated aspects constitute the tacit knowledge inherent to a practice. Hence, although capable of changing over time, such knowledge is a unique and characterized product for an office. At the same time, it is the contribution that each firm provides in shaping its community of practice, whose shared knowledge unfolds through exchanges and encounters.

ABSTRACT
The present essay seeks to point out contemporary phenomena of decreasing autonomy by the alienation of everyday skills that, together with architectural drawing, promote the architect and urbanist’s figure to that of an expert, thus immobilizing its practice in a heteronomous form. It aims the exposition, with the critiques of Ivan Illich and Sérgio Ferro, how the architect’s practice contributes to the alienation and exploitation of the construction worker’s labour in detriment of the body-skill dialectics, which would allow for a closer relation between individual and society. Opposing this alienation processes, both in consuming as in the production of architecture, with studies about technology and anthropology, it argues in favor of a politics of transformation of architectures technology based on the relation between body, skills, learning and technique.

Performing Space Through Photography

AA394585 cucina 314 420 300 3703 4961 RGB
Photography used as a tool within the architectural design process has been little studied so far. Yet, since photography implies a discourse in itself, it may turn out as being far more than a tool. By comparing two major examples the essay wants to show how the use of photography allows architects to rather perform their design ideas than merely represent them, and how the traditional architectural discourse –in particular modernism vs. postmodernism– becomes challenged. On the one hand there is Ludwig Mies van der Rohe, who pasted various photographs from newspapers and magazines in his design drawings furnishing them with an extraordinary modern atmosphere. But, as a consequence, the inherent dislocation of space and time shifts slightly the whole collage into what almost might be called a postmodern simulacrum. On the other hand there is Paolo Portoghesi who always wanted to overcome modernism’s ignorance towards architecture’s past. Despite the fact that photography has been considered as the modernist way of seeing the world, he exemplified this position by publishing a series of books on baroque architecture in Italy, equipped with compelling photographs taken by himself. They carry the reader off into the rich and tempting world of Roman baroque applying all available means of modernist photographic techniques and tricks. It will be shown that the modernist Mies and the postmodernist Portoghesi use similar visual material and techniques, but the way their photographic techniques are embedded in the broader visual discourse shifts their meaning from “seeing photographically” to the “photographic gaze”.

What sort of tacit knowledge can we glean on Zoom, when so much architectural literature on the tacit insists on prolonged physical interaction? The answer is a great deal, going by the first series of TACK Talks. Across 9 online lectures, 9 practices, 14 designers, 10 ESR respondents, 3 moderators and a weekly audience of between 85 and an astonishing 535 viewers, the TACK network joined together to tackle a deceptively simple question: ‘how do we know?’. Their responses reveal the breadth of experience and depth of reflective thinking in the network, already establishing key themes in how we conceive tacit knowledge.

Understanding the roles of tacit knowledge in the historical collaboration between AEC: a case study approach

Author: Laurens Bulckaen (picture taken) Title: Testing report of Hennebique office on the reinforced concrete floors of the Postal office in Ghent (1906) source: KADOC
ABSTRACT
This paper tries to introduce three kinds of tacit knowledge that, according to the authors, are present in the process of designing and constructing a building. By looking through the lens of the concept of tacit knowledge, collaboration between the architect, engineer and contractor, thus the building professionals is evaluated. By closely examining a limited number of key archival documents in three case studies that were already developed before, it becomes visible that tacit knowledge is an indispensable part of the intangible process of collaboration in building. Since creating buildings requires to assemble large amounts of knowledge from a wide variety of disciplines, also interdisciplinary knowledge is necessary, which is often tacit in nature. As the complexity in building grew, throughout history it also became visible that roles of the building actors started to shift and new roles emerged. Using the concept of tacit knowledge this research tries to bridge the gap of looking at the building process as a collaborative effort also showing that the building process is governed by much more than the factual explicit knowledge of only one actor.
