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.
Exchanging information so that all stakeholders share a common vision of the project: welcome to the BIM era! Every week, you can learn about one project where BIM is being used innovatively. Today we will look at L’Oréal's L6 building by Bouygues Energies & Services.
The 19th, 20th and 21st of October are the days of architecture. For the occasion, Pierrick Beillevaire, founder of the architectural firm In Situ, shares with us his vision of architectural writing combined with the comfort of use. Winner of the Design, Build, Operate, Operate and Maintain (CREM) competition for the rehabilitation of the Tertre building at the University of Nantes, these choices have made it possible to make this campus an open space overlooking the city and a comfortable environment for a student life conducive to work.
Bouygues Bâtiment Ile-de-France, Parisian subsidiary of Bouygues Construction, is the first construction company in France to set up a common tower, which is on the Tour Alto construction site in La Défense.
Operate your smartphone through thought; send a message or post a photo online without making any movement: are these practices worthy of a science fiction book in the process of becoming reality? In the future, will we have alternatives to the body for communicating with the outside world? This is the dream of the giants of the digital world who have thrown themselves enthusiastically into the field of Brain-Computer Interfaces (BCIs).
The so-called ‘tertiary’ decree, applicable since 2019, imposes a gradual reduction in the energy consumption of this type of building up until 2050. Like any new regulation, this involves a period of adaptation - especially as the objectives set are ambitious. However, the ‘Syndicat professionnel des entreprises de la transition énergétique et numérique’ (Serce) (Professional Union of Energy and Digital Transition Companies)considers them to befully attainable.
According to the UN News Centre, over two thirds of the global population will live in towns and cities by 2050. What with the increase in population and evolving ways of life and of consumption, urban centres are undergoing an in-depth transformation, accompanied by changing requirements in terms of mobility.
Several research centres around the world are working on proactive self-healing concrete processes, anticipating cracks as early as the design or the placing of the concrete.
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!
"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:
