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.

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.

Coarse epistemes: Skill, craftsmanship and tacit knowledge in the grit of the world

© TACK
ABSTRACT
In the words of Dutch archaeologist Maikel Kuijpers, craft is “a way of exploring and understanding the material world”. This definition suggests that craftsmanship can be understood as a touchstone for a theory of knowledge in material productions. By exploring the role of skill in the processes of making and its epistemic correspondence, I develop the hypothesis that craftsmanship is as a perceptive-cognitive enactment within the making process, a form of attunement with production. The argument is that the material, productive side of work deploys and operates a particular epistemological regime, based on types of practical engagement deeply related to the possibilities and contingencies of objective, concrete reality. Making means implicating oneself with the material world, embedding the body in the processes of transforming matter and partaking in the flows of forces that form things. Thus, the knowledge in the making – skill – can be understood as the invention or establishment of a new mode of perception through action that is enacted by tools, movements, techniques etc. This practical perception acts as the foundational basis on which craftsmanship is performed, representing its conditions of possibility. Given the perceptual, embodied nature of craftsmanship, its transmission is rendered impossible outside the actual engagement with production. As such, this interpretation refers back to the original distinctions made by Gilbert Ryle of “knowing that” and “knowing how” that influenced Michael Polanyi in his definition of tacit knowledge. The particular epistemic rationality of crafts provides insights for understanding knowledge inside disciplines involved with creative practice, such as architecture. The epistemic coupling with production helps to understand how architects design, but it also reveals a general epistemic schism in the discipline, founded in the inconsistency between abstract designerly knowledge and the craftsmanship of construction.

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.

Scale in passing: Re-calibrating narrowness through spatial interventions

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?

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.

REFLECTIVE ANIMATION. Navigating the What-What

© Jhono Bennett
ABSTRACT
Critically engaging with one’s positionality in contemporary architectural research in a post-Apartheid South African context requires an approach that blends concerns about identity, location, and voice in responsibly creative means, while not reinforcing the existing power dynamics inherent in such work. This essay employs Jane Rendell’s Site-Writing modality to develop a means of navigating these inter-demographic and inter-locational dilemmas - the What-What - that emerge when working from a »northerly« located institution and speaking from a »Southern« position through multiple audiences. A reflective-animation method has been developed that provides a proto-methodology for both documenting and speculating with the tacit nature of spatial design practice in post-Apartheid South African cities.

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).
