ABSTRACT

Exploring the intangible concept of diversity, the installation Living Bridge aims to use a symbiotic relationship between human and nature to provide a possible solution for future scenarios - flooded cities caused by climate changes. Symbiosis embraces two different elements, seawater and rigid metal mesh, to create natural structural elements called Biorock. Living Bridge is constantly growing and solidifying in creating new wonders and dynamics, allowing each one to enjoy the beauty of diversity. 4

WHAT IS DIVERSITY? Our idea of diversity was described through a concept video, which was later translated into a set. The final result has to be memorizable and linked to the space.

After individual research about diversity, we work together to find a more complex and meaningful interpretation and to stimulate the imagination of people. ELISA → diversity means emerging from a flat and monotonous background. Means to have some particularities or characteristics that are evident in comparison with what surrounds you. Diversity is stand out. YIDAN → diversity is an ambition to achieve impossible. As a designers we are defining the future of place, a biomimetc architecture that adapts any possible needs and conditions will allows us to live better in an uncertain environment. FRANCESCA → diversity is opening the mind to the possibility of new compositions, to have intuitions that change the subjective perception of things. Diversity is a distorted perception.

01.2 - CONCEPT

DIVERSITY IS SYMBIOSIS Humans take everything from nature for granted, leading us to a catastrophic situation. We must create a different relationship with nature and try to create a stable equilibrium. Instead of extracting from nature, we collaborate with nature. The city and architecture are created not only by humans, and only for humans, but also the nature force, for all of us. From this idea, we create a metaphor to express the possible relationship between humans and nature, showing how we collaborate together and what is the outcome.

Diversity as a consequence of the conditioning of two elements which, by coexisting, change their original status. Their interaction generates an unpredictable and sometimes surprising change.

Andrea Branzi, Simbiosi vase, 2005 The glass structure and the flower stem work together, remaining separate. The glass seems to be an unsuitable material to be intertwined with flowers, and the “supporting body� of the work seems to be the flowers. By crossing the boundaries between different logics and chemistry it is possible to create new conditions of coexistence.

It is looking for new modes of city design that incorporates the life of animals and their natural habitat into our daily existence. Moreover, the project research in which ways humans can contribute to increase biodiversity.

Living root bridge, East Khasi Hills, India, up to 500 years The living root bridges are a form of suspension of tree shaping, common in the southern part of India. They are made from the aerial roots of a living banyan fig trees. The bridge is made from the aerial roots of the trees that connect the two trunks.

→ BALANCE AND EQUILIBRIUM

Salottobuono, Teatrino, Archweek, Triennale di Milano, 2018 The roof structure is made of 8 cables anchored at the top of the base and tensioned by a helium balloon. Along the cables there is a triangular covering made of nautical fabric. This temporary installation uses balances to create a new type of roof. The materials used, if taken separately, do not have the right characteristics to create a roof. But working together, as if they were in symbiosis, they make the structure stable.

02.1 - FUNCTION

PROVIDE STABILITY Following our concept, we have identified the function of the bridge as a connection between two parts that previously had no connection. The installation aims to connect elements that usually have no common points, forcing new relationships.

01

28

Man-made structure, extremely ephemeral, unbalanced and with a short life span.

02

The man tries to find solutions to make the structure more stable. His solution is temporary, it has not a long lasting duration.


THROUGH NATURE

03

Thanks to the unforeseen help of nature, the bridge acquires stability and balance.

02.2 - SCENARIO

RISING OF The world we live in has been continuously transformed by man and is in a precarious balance. The consequences of his behavior are inevitable and are getting closer in terms of time. Global warming and sea level rise are current issues which, over the years, lead to the submergence of some cities. 30


UNCERTAIN BOUNDARIES

SEA LEVEL

2020 →

2060 →

Sea levels are rising due to melting ice and thermal expansion related to global warming. As a result of these risks, many coastal cities are already planning adaptation measures to cope with the long-term prospects of higher sea levels. → Venice, Miami, Shanghai, Mumbai, Bangkok are some of the coastal cities that will be submerged by the sea.

Our project is an installation that can be placed in any city to raise awareness on this issue. We chose the city of New York to set the project, creating strong contrasts between the urban context and the intervention of nature.

02.3 - SHAPE

WHY AN

AQUEDUCT? During ancient times it was used to “guide� the water from one place to another bringing it to the cities, where it was more needed.

In the future it will be used to connect cities and buildings since road will not be usable anymore due to the rise of sea level. Its modularity allows the bridge to be conformable to the city, adapting to its shape.

HOW WILL THE FUTURE BE?

UNDERWATER In our distopic scenario, the climate change has left much of the city under water, therefore, humans create living bridges that “invited nature to intervene� and to reconnect buildings and cities.

02.4 - GROWING PROCESS

THE LIVING BRIDGE: human structure + natural process

2020

2050

2100

Humans start to create the bridge to be prepared for this problem. The huge wireframe structures will appear in the centre of the city: these monuments remind people of the fact that the city will be flooded in the upcoming future.

When water begins to rise, the bridge starts to be used as a new connection in the city, the submerged part in the sea-water will solidify by the process of biorock.

Along with the rising of sea level, the bridge becomes an growing architecture that begins to blur the boundary between artifice and nature producing building elements.

39


THE MODULAR BRIDGE The living bridge is designed to be placed everywhere needed, and it could grow as situation of sea level. The aqueduct is made by different modules, it can be adapted to the situations in which the installation will be located. → The installation can be inserted in the city without being finished, it can grow in the following years: it is an architecture in evolution, which adapts to the rhythms of the city and nature.

03.3 - THE MATERIAL

a living material - BIOROCK is a substance formed by electro-accumulation of minerals dissolved in seawater.The biorock building process grows like marine ecosystems, such as corals in salt water. It works by passing electric current through electrodes in the water, and the structure grows more or less without limit as long as current flows.

*

The material was invented by Wolf Hilbertz (architect and marine scientist), who developed the process and registered a patent in 1979. The material is also known as “seacrete” or “seament”.

During the growth process, the structure will become a habitat for sea creatures.

The storyboard of the video shows our narrative thinking of the whole project which is based on scenario and storytelling. We tried to picture it in the New York City which is currently facing the problem, however, the project is designed for many places. While the project is based on time, we showed it in a chronological way to better convey the essential of the project.
