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.

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.

Return from the Future: The Concept of Retroactivity

OMA (1975), triptych, Boompjes Tower Slab, 1982. Colour silkscreen print, 716 × 1216 mm. Silkscreener: Bernard Ruygrok. Source: Drawing Matter
Koolhaas called his 1978 book Delirious New York a ‘retroactive manifesto for Manhattan’. In her essay Angelika Schnell describes how the concept of retroactivity is used in the architecture of OMA. Especially the high-rise project for Boompjes in Rotterdam, made between 1979 and 1981, is a design that ‘has become effective at a time in the past’. A careful reading of the accompanying text, but also the features of the design itself, reveal the circular logic of the hermeneutical model used by Koolhaas: designs are the stories that provoked the causes in the past.

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.

Book Corner: “Architecture: The History of Practice.” by Cana Cuff (1992)

© Dana Cuff
The book offers an in-depth analysis of the architectural practice culture –focusing specifically on the American one– as a “social construction”. It puts attention on the tacit knowledge seen as able to disentangle the substance of a professional ethos –affecting both espoused theory and theory-in-use, and it concludes that the design process is based on collective actions as the result of negotiations within a social process.

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.

Constructing Communities of Tacit Knowledge: Political Commitment and Urban Planning in Postwar Milan

Fig. 1 Cologno Monzese on a Saturday afternoon in the 1960s. From Casabella Continuità, n. 282, December 1963, p. 4
ABSTRACT
Exploring historical models of the construction of communities of tacit knowledge, this paper examines the contribution of leftist practitioners to Milanese postwar planning culture focusing on the communist architectural collective Collettivo di Architettura. During the reconstruction period, Milan underwent significant economic, social, and territorial transformations that intensified the divide between the city center and the periphery. The Milanese outskirts were left to speculation, rapid urbanization, and high migration rates without adequate planning tools and policies. In this context, leftist practitioners sought to address the problems affecting the Milanese periphery and wanted to contribute to their resolution. Among them, Collettivo di Architettura stood out for its explicit political stance and extensive contribution. Its members attributed social and political dimensions to architectural work and integrated collaborative ways of working and political militancy into their practice. During the 1950s, they provided free professional support in the Milanese periphery in addition to their architectural practice: as urbanista condotto, they assisted municipalities that lacked adequate planning tools and knowledge and initiated discussions with local authorities, institutions, and economic operators concerning urban development. As a result, procedures, strategies, and processes were collectively developed to establish effective planning methods and improve living conditions in the Milanese outskirts. By explicitly drawing from the Gramscian concept of the organic intellectual and the example of other committed practitioners of their time, the engagement of Collettivo’s members provided the basis for a shared planning culture. Thus, this case study highlights the significance of political commitment in generating collaborative communities of tacit knowledge.

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.

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.

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.

The Tacit Dimension [Excerpt]

The book “The Tacit Dimension” by Michael Polanyi was published firstly in 1966 at The University of Chicago Press. The following is an excerpt from the chapter “Tacit Knowing” (p. 4-13). I shall reconsider human knowledge by starting from the fact that we can know more than we can tell. This fact seems obvious enough; but it is not easy to say exactly what it means. Take an example. We know a person’s face, and can recognize it among a thousand, indeed among a million. Yet we usually cannot tell how we recognize a face we know. So most of this knowledge cannot be put into words. But the police have recently introduced a method by which we can communicate much of this knowledge. They have made a large collection of pictures showing a variety of noses, mouths, and other features. From these the witness selects the particulars of the face he knows, and the pieces can then be put together to form a reasonably good likeness of the face. This may suggest that we can communicate, after all, our knowledge of a physiognomy, provided we are given adequate means for expressing ourselves. But the application of the police method does not change the fact that previous to it we did know more than we could tell at the time. Moreover, we can use the police method only by knowing how to match the features we remember with those in the collection, and we cannot tell how we do this. This very act of communication displays a knowledge that we cannot tell.

Konvolut

The Konvolut is a growing physical product, containing important material created by the TACK network, such as readers, programs, annotated bibliography, etc. Its concept was thought as a collection in an envelope that could grow with material over time. Its nature of being in-between and a work-in-progress fitted well with the idea of tacit knowledge. It’s playful design reflects its individual nature, as each envelope has grown differently for every owner.

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.

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.
Essay

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.

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'

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.

Concrete Column, Pirelli Learning Centre

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.
