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.

Improvised architectural responses to the changing climate – Making, sharing and communicating design processes in rural Bangladesh

ABSTRACT
Bangladesh is particularly vulnerable to global climate change because of the shifting riparian characteristics of its landscape and location, with weather-driven calamities disproportionately affecting low-income rural communities. Research findings highlight the unequal distribution of responsibilities and the greater burden on women in the community to respond to the threats of extreme climate. The research methodology for this PhD by Architectural Practice therefore seeks to empower those in Bangladeshi villages by enabling marginalised voices to be heard through an emphasis on collective engagement, especially incorporating the contributions by female residents. Carried out through community-oriented projects in the remote village of Rajapur, this ‘live’ practice-based thesis explores, tests, shares and disseminates some of the rich and varied forms of tacit knowledge which can provide valuable understandings both for those people in the locality and also for architects and designers on the international scale. Responding to social and ecological ‘entanglements’ in Rajapur, the specific problems addressed are erratic rainfall patterns which create both droughts and floods, rising sea levels caused by climate change, and naturally occurring extremely high levels of arsenic-contaminated groundwater supplies, poisoning the food chain and fish in nearby ponds and lakes. How to devise affordable, low-tech solutions that utilise the tacit knowledge and skills of those living in remote villages such as Rajapur? To reshape architectural practice as an active agent for decolonising design methods, so that issues of climate change and spatial justice can be better dealt with, the research draws upon applied anthropological methods – ‘ethnography in the field’ – which prioritise local community members as the indigenous producers of design research, analytical drawings, making and storytelling. The thesis thus addresses a gap in knowledge by contributing a unique approach to participatory architectural practice, showing how it can be expanded to include rural communities in the Global South.

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.

Presence, Presentation & Representation Between Model Making and Mediation of Material in Architectural Practice during Covid-19

© Mara Trübenbach
ABSTRACT
This paper presents one specific action, i.e. a remote empirical research within a PhD project embedded in the international research network “TACK: Communities of Tacit Knowledge: Architecture and its Ways if Knowing”. The aim of the digital ethnography was to understand processes and dynamics in an architectural office in relation to new conceptualizations of the material. In asking questions about the subject in the current pandemic context, the question of the media of such an enquiry was implicated in the thesis developed. On the one side, this study is both about finding a platform on which to discuss the idea of material, and is a speculation about the implication of that platform for the ideas developed using it. On the other, it deals with using an opportunity provided by Covid-19 to make that research, via a remote ethnography with the implication that this might be used to research lots of other things beyond materials. The study hopes to create a platform for discussion around researching, observing and mediating material ¬– revising understanding as well as increasing material literacy – beyond Covid-19.

The American Pictures of the “Shrimps’ Vanguard”

ABSTRACT
The research addresses the idea of the “picturescape” as a form of episteme1, which tacitly and structurally influence the operative design modalities applied in both architectural theory and practice. The definition of “picturescape” is derived from the term “objectscape”, coined by the Leiden archaeologist Miguel John Versluys. Specularly to this notion, the term refers to the new configuration of visual culture that was caused by the emergence of the technical means of images reproduction from the beginning of the Seventeenth century onwards. During the course of the following centuries, pictures differently corresponded to the historical contexts in which they were acting, producing a substantial impact in the definition of the coeval cultures and of their related ideas of architecture. Final objective of the research is the thorough understanding of such an influence at the multiple levels at which it operated.

The Tangible Presence of Human Labor in Architecture

Alberti’s De Re Aedificatoria, © Public Domain
ABSTRACT
This essay aims to show that in many of the theories that fundament material culture and architectural experience, labor is implied in the constitution of material and, although seldom directly addressed, it is a determining dimension of materiality. From the Vitruvian and Renaissance treatises and Gottfried Semper to John Ruskin and the Art and Crafts Movement, the underlying presence of labor can be seen intertwined with materials whenever they are called into architectural discussion as sensorial arguments. Just like the physical qualities of materials, labor, skills and techniques are imprinted in the built environment and contribute to the creation of particular atmospheres.

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.

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.

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.

BODY OF KNOWLEDGE : KNOWING BODIES

Fig. 1. Sofia Pintzou, contribution to »Sasha Waltz & Guests’ Tanztagebuch«, 2020, interpreting choreographic material from Sasha Waltz’ »noBody«, first performed 2002 at Schaubühne am Lehniner Platz in Berlin, film stills from the video, online: https://www.youtube.com/watch?v=bj-dVgonIT0, accessed July 25, 2023.
ABSTRACT
This contribution addresses tacit knowledge as an embodied form of knowing and traces the potential of the body to inform and explore, contain and convey, obtain and express architectural knowledge — in the experiencing, designing, creating, and living of architectural space. If, as framed by Polanyi, »we know more than we can tell«, focusing on the body and its immanent knowledge allows to access immediate forms of architectural knowledge. Experience, memory, and the capacity for anticipation are equally rooted in the body; corporeally anchored, contained in, and inscribed to the body. Respectively, creative imagination in architectural design relies upon the body. Through knowing how we experience architecture, we are eager to anticipate future perception in architectural design. Following my doctoral thesis, entitled “Impulses and Dialogues of Architecture and the Body”, I present the knowledge of the body as a contribution to the body of knowledge of architecture: Using the example of the working method and oeuvre of Sasha Waltz & Guests – which I investigate against the background of my own artistic practice, especially in in-situ and site-specific performances, as well as my attempts at the including of somatic practices into my academic teaching in the field of architecture – I exploit the body as a medium of spatial research, and as an immediate form of conveyance and expression in the discipline of architecture.

ABSTRACT
This contribution addresses tacit knowledge as an embodied form of knowing and traces the potential of the body to inform and explore, contain and convey, obtain and express architectural knowledge — in the experiencing, designing, creating, and living of architectural space. If, as framed by Polanyi, »we know more than we can tell«, focusing on the body and its immanent knowledge allows to access immediate forms of architectural knowledge. Experience, memory, and the capacity for anticipation are equally rooted in the body; corporeally anchored, contained in, and inscribed to the body. Respectively, creative imagination in architectural design relies upon the body. Through knowing how we experience architecture, we are eager to anticipate future perception in architectural design. Following my doctoral thesis, entitled “Impulses and Dialogues of Architecture and the Body”, I present the knowledge of the body as a contribution to the body of knowledge of architecture: Using the example of the working method and oeuvre of Sasha Waltz & Guests – which I investigate against the background of my own artistic practice, especially in in-situ and site-specific performances, as well as my attempts at the including of somatic practices into my academic teaching in the field of architecture – I exploit the body as a medium of spatial research, and as an immediate form of conveyance and expression in the discipline of architecture.

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.

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.

Review

Book Corner: “Tacit and Explicit Knowledge” by Harry Collins (2010)

© Harry Collins
In this book, Collins argues that previous accounts of tacit knowledge were imprecise in distinguishing tacit knowledge from explicit, leading some writers to claim that all knowledge is tacit. Collins takes the opposite position, arguing that nearly all knowledge that seems to be tacit at first can be made explicit and that, paradoxically, it is explicit knowledge which is harder to explain and more rarely studied. He identifies an economic rationale in this focus on the tacit, particularly in management studies: tacit knowledge, transferrable through verbal or written instructions, are cheaper to provide than the ongoing training (apprenticeships, practice, socialisation,) required for explicit knowledge.

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.

ABSTRACT
What are draughtsmanship and craftsmanship in architecture and what is their relation? This question represents, of course, what could be called two distinct fields of knowledge and communities of practice, architecture and craft, and can very generally describe how their specific knowledge take shape or, in other words, through what kind of practice it is manifested.

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.
