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.

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.

Teaching Design in a Post-Rainbow Nation A South African Reflection on the Limits and Opportunities of Design Praxis

Example co-developed code of engagement (Author 2017), © Jhono Bennett
ABSTRACT
There has been an intense discourse on the relationship between inter-stakeholder university engagements, or service learning, and the broader society that South African universities claim to serve over the past decade in both local and international academia. The inherent problem within these power structures, the challenges to achieving mutually beneficial project outcomes and the growing concern of vulnerable, unheard institutional and individual voices are critical factors. The recognition of these dynamics within the emerging field of design research and design-led teaching is less nuanced in these debates. Training institutions of architecture have a rich history of undertaking service-learning initiatives to create value and learning for both the students and the stakeholders of such projects. Still, in South Africa, they are only now seen through a post-rainbow nation lens. The FeesMustFall movement is primarily driving this change. Larger institutions are recognising previously marginalised voices that now find traction in learning and practice across South Africa. This chapter reflects the author’s experience with emergent views and concerns as a researcher, lecturer and spatial design practitioner in Johannesburg. This section centres on learning regarding city-making in Southern Africa, and it presents two case studies followed by a discussion of growth opportunities.

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.

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.

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.

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.

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.

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.

ABSTRACT
The present essay seeks to point out contemporary phenomena of decreasing autonomy by the alienation of everyday skills that, together with architectural drawing, promote the architect and urbanist’s figure to that of an expert, thus immobilizing its practice in a heteronomous form. It aims the exposition, with the critiques of Ivan Illich and Sérgio Ferro, how the architect’s practice contributes to the alienation and exploitation of the construction worker’s labour in detriment of the body-skill dialectics, which would allow for a closer relation between individual and society. Opposing this alienation processes, both in consuming as in the production of architecture, with studies about technology and anthropology, it argues in favor of a politics of transformation of architectures technology based on the relation between body, skills, learning and technique.

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.
