Zeitz MOCAA (Museum of Contemporary Art Africa)\u00a0\u2013 Description de Heatherwick Studio.<\/em><\/p>

Comment transformer quarante-deux tubes de b\u00e9ton verticaux en un lieu d’exp\u00e9rience de la culture contemporaine ?<\/strong><\/p>

Depuis les ann\u00e9es 1920, l’\u00e9minent silo \u00e0 grains du Cap stockait et triait le ma\u00efs provenant de toute l’Afrique du Sud.<\/p>

Apr\u00e8s sa mise hors service dans les ann\u00e9es 1990, ses propri\u00e9taires, le Victoria & Alfred Waterfront, ont demand\u00e9 au studio de d\u00e9velopper des id\u00e9es pour adapter le silo et son site. Bien que le front de mer soit d\u00e9j\u00e0 une zone dynamique, il lui manquait une institution culturelle majeure.<\/p>

Au m\u00eame moment, la Fondation Zeitz cherchait un nouveau lieu permanent pour sa collection d’art contemporain d’Afrique et de sa diaspora. Les deux programmes ont co\u00efncid\u00e9 et il a \u00e9t\u00e9 d\u00e9cid\u00e9 que le silo \u00e0 grains serait transform\u00e9 en un nouveau mus\u00e9e d’art contemporain d’Afrique et de sa diaspora.<\/p>

Bien que le b\u00e2timent en b\u00e9ton ressemble \u00e0 une structure unique, il est compos\u00e9 de deux parties : une tour de classement et quarante-deux hauts silos cellulaires. Le principal d\u00e9fi consistait \u00e0 convertir ces tubes de b\u00e9ton serr\u00e9s en espaces adapt\u00e9s \u00e0 l’exposition d’\u0153uvres d’art tout en conservant l’h\u00e9ritage industriel du b\u00e2timent.<\/p>

Nous avons d\u00e9velopp\u00e9 un concept visant \u00e0 sculpter un atrium, comme une cath\u00e9drale vo\u00fbt\u00e9e, pour former le c\u0153ur du mus\u00e9e. D\u00e9croch\u00e9 du centre du b\u00e2timent, il donne acc\u00e8s aux \u00e9tages des galeries qui s’organisent autour de l’atrium central.<\/p>

La r\u00e9alisation du concept des tubes sculpt\u00e9s a \u00e9t\u00e9 un v\u00e9ritable d\u00e9fi technique. Model\u00e9e sur un seul grain de ma\u00efs, la forme arrondie a \u00e9t\u00e9 mise \u00e0 l’\u00e9chelle pour remplir le volume de 27 m\u00e8tres de haut, puis traduite en milliers de coordonn\u00e9es, chacune d\u00e9finissant un point dans les tubes du silo. Trac\u00e9s physiquement \u00e0 l’aide de clous, les tubes en b\u00e9ton fragile d’une \u00e9paisseur de 170 mm seulement ont ensuite \u00e9t\u00e9 recouverts de manchons int\u00e9rieurs partiels en b\u00e9ton arm\u00e9.<\/p>

Les nouveaux manchons en b\u00e9ton ont cr\u00e9\u00e9 une structure composite stable de 420 mm d’\u00e9paisseur et ont servi de guide de coupe pour le retrait de certaines parties des anciens silos. Les tubes existants ont \u00e9t\u00e9 r\u00e9duits pour r\u00e9v\u00e9ler les g\u00e9om\u00e9tries courbes de l’atrium de 4 600 m\u00e8tres cubes. Les bords coup\u00e9s ont \u00e9t\u00e9 polis pour donner une finition miroir qui contraste avec le granulat de b\u00e9ton brut du b\u00e2timent.<\/p>

\"\"<\/a>

Chacun des tubes sculpt\u00e9s a \u00e9t\u00e9 coiff\u00e9 d’un panneau de verre feuillet\u00e9 de 6 m\u00e8tres de diam\u00e8tre qui fait entrer la lumi\u00e8re du jour dans l’atrium. Le verre porte une fritte sp\u00e9cialement command\u00e9e \u00e0 l’artiste africain El Loko, inspir\u00e9 de ses \u0153uvres de l’Alphabet cosmique. En plus d’att\u00e9nuer la chaleur de la lumi\u00e8re du jour, les frittes cr\u00e9ent une surface s\u00fbre et praticable pour le jardin de sculptures.<\/p>

Les tubes internes restants ont \u00e9t\u00e9 retir\u00e9s pour faire place \u00e0 80 espaces de galerie offrant 6 000 m\u00b2 d’espace d’exposition. Les tunnels souterrains ont \u00e9galement \u00e9t\u00e9 adapt\u00e9s pour permettre aux artistes de cr\u00e9er des \u0153uvres sp\u00e9cifiques au site.<\/p>

Les proportions de la partie tour du complexe de silos la rendaient inadapt\u00e9e \u00e0 un espace d’exposition. L’\u00e9quipe de conception a repens\u00e9 cette structure comme un phare illumin\u00e9. Inspir\u00e9s par la texture vitr\u00e9e bomb\u00e9e d’une lampe v\u00e9nitienne, nous avons d\u00e9velopp\u00e9 une m\u00e9thode pour le nouveau vitrage qui donnerait un effet convexe similaire.<\/p>

La solution a consist\u00e9 \u00e0 utiliser des facettes de verre, organis\u00e9es pour cr\u00e9er une forme convexe subtile. Construite avec du verre structurel, la composition renforce les cadres de barres d’acier de 60 mm x 15 mm pour former une coque transparente.<\/p>

Formant un kal\u00e9idoscope de textures et de couleurs changeantes, le vitrage cr\u00e9e des motifs irr\u00e9guliers et \u00e9tincelants et offre des vues lointaines. La nuit, le b\u00e2timent fait office de lanterne pour le port et la ville.<\/p>
