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.

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.

Paper

From Unconventional Households to Unconventional Affordable Housing

ABSTRACT
Over the past years, a multi-disciplinary group of scholars at Politecnico di Milano (UHUAH!) has been exploring how contemporary social and demographic dynamics challenge housing policies and projects. These issues have been at the core of teaching activities in design-based studios involving architecture students. Spurred on not only by the literature on the subject (Ronald/Elsinga, 2012), we are engaged in field research investigating the state of the art of dwelling practices, with the aim to develop alternative housing solutions (and typologies) able to overcome the distance that emerged between demand and supply. A gap mostly depending on the major changes that happened in the last twenty years in households composition, and in what is typically referred to as the family (Carlson/Meyer, 2014), with the consequent crisis of the ideal equivalence between “the family” and the “apartment typology” (Star strategies + architecture, 2016). The paper will therefore present relevant case studies from the Research by Design explorations conducted on existing building stock, a decision taken to empower Adaptive Reuse as a sustainable approach also in Housing. Our Design Manifesto considers the apartment as constituted by a system of independent rooms, in which the bed is not anymore the core device, while the connective space is interpreted as common shared areas (Connective = Collective).

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.

Building worlds: architecture as speculation on society

As part of The Persistence of Questioning, critical reflections for the future: ‘What is architecture?’, Lara Schrijver argues that Science fiction in particular can help architecture to consider unforeseen consequences of design decisions. We thoroughly need to recognize how on the one hand the environment and society are connected, and how on the other hand the future remains difficult to predict.

City as Forest

We understand the city as a forest: a complex (eco)system in which various spatial elements are synergistically and dynamically networked. In this sense, with every design, the challenge and the opportunity arise to contribute to the system as a whole rather than creating a solitary object.

The Royal National Theatre from Architectural Review to TikTok

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.

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.

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.

Post CIAM

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.

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.

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.

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.

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.
