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: Canteiros da Utopia

The book Canteiros da Utopia, whose title can be translated as Construction Sites of Utopia, is the result of Silke Kapp's Post-doc research in Urban Sociology from the Bauhaus Universiteit Weimar, conducted between 2014 and 2015. Being Kapp’s supervisee during my Master’s studies in Architecture and Urbanism at the same university, which I had the pleasure to read still in its pre-printed version. Kapp’s ability to converge imaginative and critical thought is fully represented in this oeuvre, turning the experience of reading it one of both great literary joy and intellectual stimulus.

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.

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?

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.

Architectural Ethnography? Incipits, distances, horizons for research and teaching practices

Figura 1 – profili degli abitanti e nuove tipologie di stanze (ReCoDe 2019), © Gennaro Postiglione
ABSTRACT
Architectural ethnography has increasingly been a focus of attention thanks to recent studies carried out by Albena Yaneva or to practices and research carried out by Momoyo Kaijima with her Atelier Bow Wow. Starting from an interest in the specificities of ethnographical approaches if practiced by architects, or by professionals and researchers having particular attention to forms, materiality and uses of the space in the everyday, this article outlines a literature review on ethnography for designers. This review has been helpful in defining through convergences and distances a specific positioning that we are assuming in teaching and doing research for design. A path that led to further questions on the role of transcription (graphical, photographic, textual) in architectural ethnography, as well as to challenging the role of tradition and innovation in this recent stream of research.

POSTHUMANIST SANDBOX: THE POTENTIAL OF MULTIPLAYER – ENVIRONMENTS

ABSTRACT
This paper seeks to reveal a novel assessment of creative production in academic education, re-evaluating the conceptual and artistic potential of virtual real-time collaboration through digital media. Allowing for transcultural exchange as well as global participation, this could positively influence the development of novel artistic approaches and innovative measures for universities by contributing to a more contemporary, location-independent, and ultimately more equal form of art and knowledge production.

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.

It was captured on film by Jaap Bakema. After the demise of CIAM, Bakema initiated a newsletter to keep the network updated.

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.
