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.

Playa Blanca, Bankers, and the Pivotal Point

I made this 1:200 working model entitled ‘Playa Blanca, Bankers and the Pivotal Point’ during my time at the Städelschule Frankfurt. The three-dimensional knot bent from copper wire combines investigations into rotational symmetries, the programmatic linking of living and working environments, and early aesthetic explorations into the consequences of parametric design models. This physical model formed the basis for a series of digital models whose gene codes continue to shape the work of our office in terms of methods and aesthetics to this day.

Clay 3D Print of Urmein

The model displayed here, a Clay 3D Print of Urmein, a rural village in Switzerland, highlights the exploratory path that architects often take when new technologies become available. The model is based on information drawn from photogrammetry and drone footage, and has been produced by a clay printer intended for pottery – all tools that do not typically belong in the architect’s toolbox.

Exploring Spatial Perception through Performative 1:1 Extended Reality Models: Preliminary insights from Infra-thin Magick

© TACK
ABSTRACT
Building on scenography, performance theory and findings from neurosciences, tacit knowing in architecture is understood here as embodied, embedded and enacted perceptual dimension of our built environment. Through art- and design-based research, tacitly knowing is examined as a form of practice and a new extended reality (XR) design tool is probed to exercise it. Since the atmospheric turn in architecture (Böhme 2017, McCormack 2014, Bille et al. 2015), it is well known that spatial perception is multi-sensory and that the interplay of our senses goes beyond the cross-fertilization of sight, touch, taste, smell and hearing. Nevertheless, architectural designers may have only touched the surface of what we might be able to feel regarding our spatial environments. Apart from the sensation of our movement and whether our environment is too hot or cold, our abilities to feel space physically remain challenging to represent and communicate through conventional architectural tools. This includes i.e. our sense of balance, our ability to feel time passing, our knowledge of which of our body parts are where without having to look at them, and our sense of gravity, orientation, and illumination. Some of these “always-there-but-never-felt” sensations can be revealed and physically experienced when entering a fully immersive virtual environment for the first time. As our brain takes a split second to adjust to the novel surroundings, it is at this moment that we can suddenly sense our senses at work. The XR case study “Infra-thin Magick”, exhibited as part of Speculative Fiction at the Academy of Fine Arts Vienna in 2022, explains how such unanticipated insights can be purposefully evoked by displacing and reassembling the components constituting our multimodal and synaesthetic spatial perception. Leaning on the design theoretician Thea Brejzek and Lawrence Wallan’s understanding of the “autonomous model”, this performative real-time and -scale XR model that oscillates between physical installation and virtual reality (VR) experience is employed as an operative tool for designing and analyzing spatial experiences beyond the known sensations of our built environment. First user-testing results are presented, and the premise of the autonomous model to co-create reality and allow architects to research through active participation, first-hand experience, discovery, and play are brought to light.

Urban Predation: The symbolic economy of the Pixo

Image 02: Denilson Baniwa Yawareté Mural Artist: Denilson Baniwa Photo: Rafaela Campos Alves , © Creative Commons
ABSTRACT
This essay proposes an analysis using the “symbolic economy of predation” to provide new perspectives on the question of pixo. For this, pixo will be considered as any act on walls, building facades, asphalt or monuments rejecting the hierarchical separations between writing, scribbling, painting or graffiti imposed by the art system and other institutions. In Amerindian ontology, as Viveiros de Castro describes, the feeding regime is the predominant model upon which relations are perceived. The predator and prey duality stands as the archetypical role ruling interactions between different subjectivities and perspectives. This “symbolic economy” permeates social relations and translates them into a particular epistemology shared by many indigenous peoples throughout the Amazon region. We aim to consider the relationships between those who practice pixo and the city through an analogy with the predator and prey dialectic. We argue that, on the one hand, these taggers get symbolical dominion over the city’s territory by marking places with their signatures, thus gaining recognition from their peers; on the other, the city - represented by formal governmental and economic institutions - preys upon taggers by criminalizing their practice as vandalism and by socioeconomically excluding peripheral populations, thus denying their access and right to the city itself. Pixo is a reaction to the passive role imposed on society that gains critical and artistic qualities as a practice of protest, endorsing its predatory performance. This analogy intents provide a new perspective to describe the city and its complex relations with the aesthetical and social realities of its inhabitants. A distinct description of the urban relations that might enable planners and policymakers to evaluate socio-political phenomena within the city through a new set of lenses, allowing the development of innovative approaches to tackle and decriminalize conflictual practices as the pixo.

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.

The drawing as a synthesis is made after the project is built or the competition is over. This kind of ‘drawing made afterwards’ is about bringing all the principal ideas and responses that now already exist into a drawing. It is a synthesis, and like a poem it reduces or condenses the new reality of the project and describes it all at once very precisely.
