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.

The idea of reusing materials resulting from renovation or demolition work is gaining momentum. It has to be said that it is very attractive since by reviving this age-old practice, there is indeed much to be gained - new means of recycling, low-cost materials, improved carbon footprint during activities, etc... The list is long. All that remains is to remove any barriers.
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.
Every day, concrete endures attacks of all kinds (carbon dioxide from the air, chlorides, etc.). These aggressive substances corrode the concrete's metal reinforcements and cause deterioration. Unavoidable? Yes. Disastrous? No – not if you know exactly when to do renovation work.
To meet the needs of both patients and healthcare workers, each healthcare site must combine reliability with ease of use. This fact is not always taken into account. This is evidenced by the numerous problems pointed out by users relating to space and practical issues. However, whether in care homes or hospitals, the building can be a valuable asset in taking care of the most vulnerable and allowing health professionals to work in the best possible conditions. This is a major challenge that Bouygues Construction wants to address using digitisation.
