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.

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.

Traveling Perspectives: Tracing ‘impressions’ of a project in Flanders

Fig. 6.2: Focus on the front façade of the BMCC. Photographed December 2022.
ABSTRACT
The collection of localities that play an active (and overlooked) or quiescent (yet potent) role in architectural practices are put in question here. The chapter investigates how a project and its site specific geographical setting can contain traces of broader architectural contexts. It asks how architectural collaborative approaches that stem from the encounter of different perspectives can be read in the lived environment through the lens of plurilocality. Distinct yet intermingling perspectives of a contemporary architectural realisation are drawn out through a dive into the meeting and convention centre in Bruges. This is a building designed by two offices based in different architectural environments — the Portuguese practice Souto de Moura Arquitectos alongside the Antwerp-based firm META architectuurbureau. Various perspectives of the same building are set in parallel, exploring place through similarities and differences. From different modes of apprehending the project, concepts of place and architectural intentions set in motion in this instance are unpacked, involving a transversal reading through a broader architectural community of practice. Active instances of getting to know a place through experience can thereby be tacit yet situated: they can be embodied, embedded and enacted. This further explores Maurice Merleau-Ponty’s hint of a depth found in the latent form of impressions, in their ‘caché-révélé’ or hidden-revealed. Expressions of such instances, through interpreting reflexive features of buildings that stem from plurilocal collaborations, become productive insights into the mechanisms of place relation, their transfers and interweaving, and their impact in architectural design practices. Most of all, these parcels of the tacit dimension of place interpretation are put forward as such: aggregates that interfere with- and feed a relation-full practice of living environments.

Book Corner: ‘Pre-Positions’, in Site-Writing: The Architecture of Art Criticism by Jane Rendell (2010)

Rendell, J. (2010) ‘Pre-Positions’, in Site-Writing: The Architecture of Art Criticism
The introduction to the author’s positional body of work, sets the theoretical and intellectual context for the ideas underpinning Site-Writing as a practice and their aims in giving voice to this form of practice. The author uses seminal writers on phycology, art-practice and philosophy as figures to guide their later theories and discusses the relationship between architecture and art-critique as reflective and positional practices.

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.

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.
