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.
"Our subsidiaries Bouygues Thai and Bouygues Energies & Services, in a joint venture with the local company McTric, have built four solar farms in Ayutthaya, 100km north of Bangkok,in Thailand. Back in pictures on this amazing project:
How has BIM tech improved productivity? What are its most innovative applications in construction? What can we expect from BIM in terms of Big Data? Martin Fisher, Professor of Civil and Environmental Engineering at Stanford University, answers all our questions!
In 2019, France set itself the target of achieving carbon neutrality by 2050. If we are going to meet this climate commitment, we need to speed up the country's decarbonisation and redefine the energy system, two-thirds of which still depends on fossil fuels. At a time when the country is launching consultations on the future French Strategy on Energy and Climate, which will serve as the national roadmap for achieving carbon neutrality in 2050 and adapting our society to the impacts of climate change, three projections performed by ADEME (the French agency for ecological transition), RTE (the French transmission system operator) and NégaWatt (a think tank) question the energies of our future.
Today, 300 million tons of plastic are produced each and every year worldwide, including more than 60 in Europe, where packaging accounts for the vast majority of single use plastic. Where does it go and how can it be used in 3D printing?
Being part of the electricity production system is something that is appealing to more and more French people. But what is energy self-consumption really?
Buses, underground systems, trams, car-sharing or short-term rental cars, car-pooling, mini-cab services, bikes, mopeds and self-service scooters, with or without stations: with the proliferation of forms of mobility, the residents of major cities have never had so many means of travel available to them.
The issue of free public transport was widely debated in France’s 2020 municipal elections. Its presence on the headlines of many campaign documents demonstrates the political, environmental and societal nature of the issue. Several issues arise from the implementation of such a public policy. We examine the positions of the key stakeholders in the debate.
Cast in situ, precast twin walls, precast slabs, modular construction, 3D printing... how do you choose? This, in essence, is the research project being carried out by Emna Attouri, a PhD student participating in the Chaire Construction 4.0 research
This area will be a great place to work, take it easy and unwind. The location, known as ‘Quai 22’, with its mix of city life, water and nature, will be situated on the banks of the river Deûle in the European Metropolis of Lille.
