Whether figuratively or in an urban context, bridges are a strong symbol and often become iconic projects in cities. Building bridges can mean creating connections, new opportunities. But they are also fundamental pieces of infrastructure that solve specific issues in an urban context. As these involve highly technical equipment, with complex constructions and overwhelming bold structural requirements, they require projects that do not need full integration between architecture and engineering and, in many contexts, is a type of projects that architects are not so involved with. Marc Mimram Architecture & Engineering is a Paris-based office comprised of an architecture agency and a structural design office. In its project portfolio, there are several bridges, as well as various other project typologies. We spoke with Marc Mimram about his latest project in Austria, the bridge at Lins, photographed by Erieta Attali.

Slate is a metamorphic rock formed from the transformation of clay under high pressure and temperature. Very homogeneous and sober, with shades ranging from dark gray to black, it is commonly used in floors and roofs due to its durability and appearance. Slate also works very well for façades, combining the aesthetics of natural stone, shaped by nature for over 500 million years, with the thermal comfort and ease of installation of ventilated façades.

Josep Ferrando is an architect based in Barcelona. He is the Dean of the La Salle Higher Technical School of Architecture (ETSALS), as well as Director of the Obert d’Arquitectura Center of Barcelona and of the Department of Culture of the College of Architects of Catalonia (COAC). Combining his academic career and his frequent lectures, his office develops projects that explore different scales and materials, experimenting with constructive systems and innovative solutions. We talked with him about the importance of materials in architecture, and about the synergies he finds between practice and teaching.

For some, it may be terrifying to think that we inhabit a sphere orbiting the Sun, whose core has temperatures of up to 6,000°C and all human activities are located on the Earth’s crust, the smallest layer in thickness, in the so-called tectonic plates. These plates float on the mantle, more precisely in the asthenosphere, and sometimes collide, causing earthquakes. As we can see in this interactive map, earthquakes are much more frequent than we imagine, with dozens occurring daily around the world, many of them unnoticed. But some are extremely potent, and when they occur near urban areas, they are one of the most destructive forces on Earth, causing death and damage to the built environment.

Pink Floyd’s song “Another brick in the wall” criticizes an alienating and demotivating educational system. People, or children, are portrayed as bricks due to their homogeneity, whether in the way of living or thinking in a society that is not very fond of opposition. Bricks work very well in this comparison, having changed very little throughout history and around the world in their rectangular shapes. But that’s not true of their colors. Although we tend to think of red when we talk about bricks, there are infinite possibilities of shades, depending on the composition and manufacturing process of the pieces.

“If the cement industry were a country, it would be the third-largest emitter of carbon dioxide in the world, with about 2.8 billion tons, surpassed only by China and the United States.” This statement in Lucy Rodgers’ BBC report on the ecological footprint of concrete stands out as quite shocking. With more than 4 billion tonnes produced each year, cement accounts for around 8 percent of global CO2 emissions and is a key element in the production of concrete, the most manufactured product in the world. To give you an idea, about half a ton of concrete is produced per person in the world every year, enough to build 11,000 Empire State buildings. With these huge numbers, is there any way to reduce this impact?

The concept of prefabrication in construction corresponds to elements, parts or entire buildings produced in a factory and transported to a construction site for a quick installation. This represents numerous advantages over traditional construction methods, such as speed, precision in execution, efficiency, cleanliness of the work and, in many cases, cost. Considering that housing is a primary human need, using industrial methods for the construction of affordable and good quality housing has always interested architects, whether to house growing urban populations or for temporary or emergency settlements, on the most diverse scales. After many attempts throughout history, the question remains whether the popularization of prefabrication in the construction field can be a solution to provide greater equity in access to housing.

Researchers credit the Hanging Gardens of Babylon as the first examples of green roofs. Although there is no proof of its exact location and very little literature on the structure, the most accepted theory is that King Nebuchadnezzar II built a series of elevated, ascending terraces with varied species as a gift to his wife, who missed the forests and mountains of Persia, their local land. According to Wolf Schneider [1] the gardens were supported by brick vaults, and under them, there were shaded halls cooled by artificial irrigation of the gardens, with a much milder temperature than the outside, in the plains of Mesopotamia (present-day Iraq). Since then, examples of green roofs have appeared all over the world, from Rome to Scandinavia, in the most diverse climates and types.

The choice of Lacaton & Vassal to receive the 2021 Pritzker Prize was, above all, emblematic. Under the mantra “never demolish, never remove or replace, always add, transform and reuse”, the French duo built a career focused on renovating buildings, providing them with spatial quality, efficiency and new programs. Their approach contrasts with most of the architecture we are used to honoring: iconic, imposing and grandiose works. It also contrasts with the notion of the tabula rasa, of building and rebuilding from scratch, so well represented in Le Corbusier’s Ville Radieuse, and which has fascinated architects and urban planners ever since.
