What is the link between buildings and mobility?
In theory, there is none ... The world of mobility is changing and is no longer limited to transport.
It's the world's longest sea-crossing bridge: 55 kilometres of motorway spans the Pearl River Estuary in the South China Sea before dipping into an undersea tunnel. The Chinese President Xi Jinping has today officially opened the gigantic infrastructure linking Hong Kong, Macau and mainland China. A colossal engineering structure, involving the Bouygues Construction subsidiaries Bouygues Travaux Publics, Dragages Hong Kong and VSL for the construction of a 9.4-kilometre section.
A bridge of strategic importance 5714 prefabricated segments of 250 different types, laid down at the rate of 18 per day, shaft grouted friction piling method to cope with difficult ground conditions – a technical first in Hong Kong –, sea-based installations and specific logistical arrangements to maintain the waterways throughout the duration of the works... Some notable innovations for the construction of this extraordinary bridge structure. It is now possible to reach Hong Kong from the main cities of the Pearl River delta in 30 minutes, compared with four hours by land and one hour by boat. A real basis for stimulating commercial ties between the two sides of the crossing.

Developing the city with water: managing resources and coping with the risk of flooding
In France, 1 in 4 people and 1 in 3 jobs are exposed to the risk of flooding, through overflowing watercourses or rising sea levels[1]. In more general terms, floods are a major natural hazard in several regions of the world. These risks are now accentuated by climate change and the increase in extreme weather episodes, including intense rain events in particular. In an urban environment, characterised by a strong increase in soil impermeability, these phenomena promote runoff and associated pollution and lead to congestion and flooding. In addition, urbanisation in flood-prone areas is a major economic and social issue for local communities. To meet these challenges, new approaches are being developed to provide better ways of living with water in cities.

The longest sea viaduct on French territory
This 5,400 metre-long sea viaduct, which will connect Saint-Denis (the capital of Reunion Island) to La Grande Chaloupe, is a major component of the New Coastal Road. The aim is to replace the current road along the coast between Saint-Denis and La Possession, which is dangerously exposed to the risk of rock falls and submersion […]

Time, a key resource for cities
Today’s cities face many challenges. The ecological emergency is pushing us to reduce our carbon footprint, to halt the sprawl of cities into natural areas, to preserve natural resources and to fight against the collapse of biodiversity.

How to design a welcoming city for people with disabilities
In February 2005, France adopted a law making it mandatory for cities to create a living environment adapted to people with disabilities by making urban areas accessible to all within 10 years. However, the additional time granted and the leniency shown due to difficulties cities faced in meeting the established deadlines have greatly brought down the initial goal.

Laure Abdul, PhD in Materials Engineering, presents the concept of soil cement.
Given the backdrop of depleting resources such as sand and the saturation of landfills in Île-de-France, and due to the volumes excavated for this work, the idea of reusing the land excavated for new construction was very appealing.
