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.
Purchase housing without paying for the land it stands on. Savings of between 20 and 50% are now possible thanks to the French “bail réel solidaire” leasehold arrangement provided for by the ALUR law and specified late last year by the ELAN law
Nature provides an endless source of inspiration. Observing nature to inspire technological innovation is the very essence of biomimicry.
Hydrogen has been put forth as a critical "green" energy solution in the next decades. Between public and personal transport, power production and storage, the innovations are proliferating around the world to make hydrogen a central part of our daily lives.
Bouygues UK, subsidiary of Bouygues Construction, was awarded the construction of an iconic project for Keele University in the Midlands – the Smart Innovation Hub project.
Erected for the Departmental Council and the firefighters of Ille-et-Vilaine, the building was designed and built by Bouygues Bâtiment Grand Ouest. The technical training facility has a new innovative tool, the goal of this unusual construction being to give firefighters a place to train in conditions as close as possible to the real thing! The […]
The first part of the 6th assessment report of the IPCC, published in August 2021, made blatantly clear how important it is for us to meet the commitments made under the Paris Agreement by limiting global warming to less than 2°C, preferably to 1.5°C, and to achieve carbon neutrality by 2050. The construction sector, one of the main emitters of greenhouse gases, is particularly concerned. It accounts for 19% of emissions in France (not including associated emissions such as electricity and heat production). At the heart of the sector’s low-carbon transition, the diversification and decarbonisation of building materials is an important lever: this covers the structuring of bio-sourced and geo-sourced materials, the development of solutions from the “dry sector” (reuse, prefabrication), and the emergence of new ranges of low-carbon concrete. The challenge is to be able to use the right material in the right place, according to the specific context of a given territory and a particular project. We turn the spotlight on low-carbon concrete: what processes and techniques does this term suggest and what does it promise?
Bouygues Construction and Centrale Lille recently inaugurated the Construction 4.0 Chair, a partnership that represents the culmination of a 15-year relationship widely supported by the region and city. Two theses are already in the works. We met with the PhD students behind them.
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.
How do we do more with less? Modern cities are faced with numerous challenges. They need to emit less carbon and halt urban spread into natural areas, while also having enough space to live in social harmony and in line with shifting trends (reconstituted families, telework, etc.). With these contradictory demands—acquiring more space with less sprawl—time becomes an unexpected resource. Some spaces in our buildings are used only for certain times of the day, week or year. For example, educational facilities are generally used around 20% of the time, while offices are used between 30% and 45% of the time. This means they can be used more, by finding new users and new ways to use them. Let’s look at a few concrete examples.
