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.
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 […]
On the pavements of our neighbourhoods, the cries of children are becoming increasingly rare. They are replaced by the noise of cars and hurried adults who no longer seem to know how to stop, wander or stroll... How is this harmful to the accessibility of our cities?

(Français) Le vieillissement de la population n’est pas un phénomène nouveau. Mais l’augmentation de l’espérance de vie en bonne santé et l’arrivée massive des baby-boomers à la retraite accélèrent fortement le phénomène. Pour preuve, il y a en France depuis 2015 plus de +65 ans que de -18 ans ! Et en 2030, un français sur 3 aura +60 ans. Qui sont les seniors ? Quels sont leurs besoins et attentes ? Quelles implications sur les offres d’habitat ? Découvrez ci-dessous quelques éléments de réponse.
Aude Launay, an intrapreneur supported by the Bouygues Group, talks us through the Flexy Moov concept.
Regeneration is on the rise, in particular in the context of social housing. All over France, priority neighbourhoods are being revamped. The goal is to provide more comfort to inhabitants while reducing the energy consumption of their homes. This reduction has been challenged by the France Relance plan. The plan requires that social housing reach at least class D in the Energy Performance Diagnosis (DPE, acronym in French) and be awarded at least two labels. With new environmental challenges and new expectations from inhabitants today, the link between regeneration, energy saving and comfort has never been this clear... And not just for social housing!
In the last segment of its sixth activity report, the GIEC specifies very clearly that on the economic level, the ecological transition will prove less expensive for the global economy than if we do nothing. Several sectors are highly exposed to this issue, in particular transport, energy and construction. But acting, how much will it cost? The subject is a complex one but initial estimates are starting to be seen.
