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.

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'

ABSTRACT
Reflecting on the art installation Motion of Scales, which was temporarily installed in the city centre of Kolding, Denmark, as a part of the NORDES 2021 conference, this article explores the interrelation between body, material and its performative potential. Analysing the design process through description and observation of how it was experienced and interacted with by urban public, the design-led research aims to interrogate subjectivity, emotion and embodied knowledge in academic research and its methods. How could movement within scale open up new perspectives? Does material hold a potential to reveal new modes of thinking in design research? How and to what extent could emotion contribute to design practices?

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.

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.

Glassplitter / Broken glass

Near the end of the previous century, waste recycling became more common in Switzerland – not only for paper, but also metal and glass. While developing the plans for the Kirchner Museum Davos in 1989, we had the idea to use waste glass as roof covering for the glazed building, instead of gravel or sheet metal. Glass has a similar weight to gravel and is therefore well suited for ballasting flat roofs. Without much effort, the cullet could be taken from the recycling process before remelting.

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.

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.

Archives. On The Genesis of Architectural Design

ABSTRACT
This essay highlights the ‘archive’ as a productive and inspiring factor in architectural design. As one can observe in publications, interviews, and lectures of some contemporary architects as Sauerbruch Hutton, Brandlhuber I Kniess, Valerio Olgiati, John Pawson or EM2N for example, different kinds of archival operations might form triggers for the generic processes of basic conceptions as well as for project-oriented design actions and last but not least for the attitude and stabilization of the architects’ work and profile. With the lens of interpretations of the archive initiated by Michel Foucault and other French theorists of science and historians since the 1960s up to contemporary discourses, it is possible to show via analogies of acting and reflecting the powerful qualities of the ‘archive’ and of archival operations in the dynamic processes of architectural design.

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.

Exploring Spatial Perception through Performative 1:1 Extended Reality Models: Preliminary insights from Infra-thin Magick

© TACK
ABSTRACT
Building on scenography, performance theory and findings from neurosciences, tacit knowing in architecture is understood here as embodied, embedded and enacted perceptual dimension of our built environment. Through art- and design-based research, tacitly knowing is examined as a form of practice and a new extended reality (XR) design tool is probed to exercise it. Since the atmospheric turn in architecture (Böhme 2017, McCormack 2014, Bille et al. 2015), it is well known that spatial perception is multi-sensory and that the interplay of our senses goes beyond the cross-fertilization of sight, touch, taste, smell and hearing. Nevertheless, architectural designers may have only touched the surface of what we might be able to feel regarding our spatial environments. Apart from the sensation of our movement and whether our environment is too hot or cold, our abilities to feel space physically remain challenging to represent and communicate through conventional architectural tools. This includes i.e. our sense of balance, our ability to feel time passing, our knowledge of which of our body parts are where without having to look at them, and our sense of gravity, orientation, and illumination. Some of these “always-there-but-never-felt” sensations can be revealed and physically experienced when entering a fully immersive virtual environment for the first time. As our brain takes a split second to adjust to the novel surroundings, it is at this moment that we can suddenly sense our senses at work. The XR case study “Infra-thin Magick”, exhibited as part of Speculative Fiction at the Academy of Fine Arts Vienna in 2022, explains how such unanticipated insights can be purposefully evoked by displacing and reassembling the components constituting our multimodal and synaesthetic spatial perception. Leaning on the design theoretician Thea Brejzek and Lawrence Wallan’s understanding of the “autonomous model”, this performative real-time and -scale XR model that oscillates between physical installation and virtual reality (VR) experience is employed as an operative tool for designing and analyzing spatial experiences beyond the known sensations of our built environment. First user-testing results are presented, and the premise of the autonomous model to co-create reality and allow architects to research through active participation, first-hand experience, discovery, and play are brought to light.

Through art- and design-based research, tacitly knowing is examined as a form of practice and a new extended reality (XR) design tool is probed to exercise it. Since the atmospheric turn in architecture (Böhme 2017, McCormack 2014, Bille et al. 2015), it is well known that spatial perception is multi-sensory and that the interplay of our senses goes beyond the cross-fertilization of sight, touch, taste, smell and hearing. Nevertheless, architectural designers may have only touched the surface of what we might be able to feel regarding our spatial environments. Apart from the sensation of our movement and whether our environment is too hot or cold, our abilities to feel space physically remain challenging to represent and communicate through conventional architectural tools. This includes i.e. our sense of balance, our ability to feel time passing, our knowledge of which of our body parts are where without having to look at them, and our sense of gravity, orientation, and illumination. Some of these “always-there-but-never-felt” sensations can be revealed and physically experienced when entering a fully immersive virtual environment for the first time. As our brain takes a split second to adjust to the novel surroundings, it is at this moment that we can suddenly sense our senses at work. The XR case study “Infra-thin Magick”, exhibited as part of Speculative Fiction at the Academy of Fine Arts Vienna in 2022, explains how such unanticipated insights can be purposefully evoked by displacing and reassembling the components constituting our multimodal and synaesthetic spatial perception. Leaning on the design theoretician Thea Brejzek and Lawrence Wallan’s understanding of the “autonomous model”, this performative real-time and -scale XR model that oscillates between physical installation and virtual reality (VR) experience is employed as an operative tool for designing and analyzing spatial experiences beyond the known sensations of our built environment. First user-testing results are presented, and the premise of the autonomous model to co-create reality and allow architects to research through active participation, first-hand experience, discovery, and play are brought to light.

COMMON GROUND. Discursive Orders in Architecture

ABSTRACT
Is it possible to characterize the relation of architecture and science, if it is not derived from established scientific conventions? This essay highlights one field of the multifaceted spectrum, which pops up in the context of this question, a field, which can be observed when expanding the focus from science to knowledge and processes of its formation and transformation. Focal point will be the question where and in which ways knowledge appears and marks a `common ground´. The investigations are revolved around the most important field of thematisation and mediation of architectural reality at the beginning of the 21st century to be found globally, the International Architecture Biennale, which takes place in Venice in a two year cycle. Furthermore special attention will be riveted on the biennale of 2012, which was dedicated to the theme `Common Ground´. The following notions are enmeshed with the consideration, that with a presentation and uncovering of knowledge and communication on it, we have here a kind of discourse in architecture that might not only process attitudes and a stabilization of the discipline, but also provides triggers for generic processes of scientific contexts and basic understandings of research and design in architecture.

The drawing as a synthesis is made after the project is built or the competition is over. This kind of ‘drawing made afterwards’ is about bringing all the principal ideas and responses that now already exist into a drawing. It is a synthesis, and like a poem it reduces or condenses the new reality of the project and describes it all at once very precisely.

ID – Integrated Processes of Reading and Creating Post Objects in Digital Design

ABSTRACT
This paper investigates a mechanism for generating a logic that describes an under-design object by its user in a digital design medium (AutoCAD by AutoDesk) through a deconstructive tracing of the design process. The mode of deduction and the research results aim to measure the by-design idiosyncratization, a subject-oriented process of understanding and reacting to a deeper structure. Creating multiple, independent, and autonomous correlations of the design language structure and its representation during the design process leads to new associations accessing the notion of Post-Object. This socially and culturally expected mode revokes a singularization process. At the same time, the User-Interface relationship provides correlations between a personal and unique selection of things and the necessary infrastructure to actualize and activate them. The process of collecting and crafting an expression is dispositive of singularization. Crafting a method of relating the design of objects to subjects and the use of language to form questions about how contemporary design is constituted and the multiple ways of conceptualizing contemporaneous subjectivities and implicitly post-industrial societies and economies.

Hunting Tacit Knowledge: Encounters in architectural education at ILAUD and ETH

ABSTRACT
Tacit knowledge in architectural education is slippery. It encompasses a broad range of unconscious, embodied, social and otherwise hidden forms of knowing. On one hand, this means that it manifests in different ways depending on the pedagogical format or context. On the other, it resists explanation through the traditional, and largely explicit, tools of academic writing. Therefore, rather than seeking to define it, this paper proposes three approaches for locating and describing it. First, forms of tacit knowing—which we rely on, often without thinking, in our studio, school, or regional culture—become more visible in “moments of encounter” between communities. Second, discussions and negotiations of tacit knowledge often occur through architectural materials: drawings, models, texts, buildings. Third, “moments of tacit encounter” require more evocative and speculative methods of writing and representation, with different evidentiary standards. To test these approaches, this paper narrates two “moments of encounter” as case studies, encompassing different pedagogical formats, actors, writing methods, and revealing different forms of tacit knowledge.   In 2020, I arrived at ETH Zurich, where I began an autoethnographic study of tacit knowledge in discussions between critics across design studios. I was drawn to the realistic models of Studio Caruso, which I first encountered in my architectural studies in Australia. There, they represented a hitherto unimaginable departure from model abstraction. In Zurich, though, some critics were less dazzled, questioning the labor they required. Elsewhere, realistic models had been at the center of right-wing outrage over a kiosk designed by Caruso’s office in Escher-Wyss Platz in 2007. Around these models, the tacit architectural expectations of various groups seemed to reveal itself.   In 2021, I organized a summer school in Rotterdam on summer schools. Over five days, we re-enacted a charette exercise originally set for the 1986 edition of the International Laboratory of Architecture and Urban Design (ILAUD): the summer workshops founded by Giancarlo de Carlo in Urbino. Summer schools are ephemeral in nature—intense, productive, social, life-changing, but only for a few weeks—leaving little evidence of their tacit dimension for us to study today. Re-enacting it ourselves, coming from different educational backgrounds, we started to understand something of what it must have felt like in 1986. We experienced the clashes and arguments, and overcome them through drawings or by discussing images, by talking in those informal moments on the staircase or over lunch.

Investigating the 21st Century Emerging Approaches to Practice: Codification of Architectural Epistemes, from Discourses to Practices

© Claudia Mainardi
ABSTRACT
Given the timeframe of the last 20 years, the research investigates the codification of diverse forms of tacit knowledge in architecture, its transfer, and translation from institutional narratives to principles and conventions that are crystallized in the everyday practice of selected design offices. Positioned into the lines of theories that see architecture as “a product” of a socio-political-economic condition, the aim is to understand how events that have occurred/are occurring in current times influence the professional practice and, consequently, its codes. The work is imagined to be developed through three phases. A first part –conceived as macro- analysis– is proposed as an attempt to reconstruct a historical framework of events not yet historicized; a second and intermediate one identifies the protagonists –or the practices that the research is interested at–; and a third one –as micro- analysis– made of in-depth investigations of case studies selected through the protagonists of the second phase.

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.

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.
