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.
Wood construction is currently gaining ground in all construction sectors. And this is only the beginning! In the context of decarbonisation of the building sector, the RE2020 is bringing bio-sourced materials to the forefront. Let’s take a look at a flourishing sector.
Whether in the interests of comfortable living or to reduce energy consumption in homes, connectivity is increasingly present both in individual housing and multi-unit buildings. An advantageous transformation that might well lead to the embedding of certain technologies in all new housing.
Sharing information so that all the players in a project have a shared vision of the works. Welcome to the world of BIM! Every week for a month, discover one of our sites where BIM is being used in an innovative way. Today we discover the Alto Tower by Bouygues Bâtiment Ile-de-France.
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.
Since November 2015 more than 100 site workers from Bouygues Energies & Services have been working to build a next-generation thermal power plant in Gibraltar. The aim of the project is to replace three fossil fuel power plants dating from over 30 years ago, which no longer meet European requirements. The biggest challenge in the […]
Around 28% of the world’s animal and plant species are now under threat of extinction . This includes one in four mammal species, one in seven birds and more than one in three amphibians, as well as a third of conifer species. Scientists are warning of an ongoing collapse of biodiversity, with some even talking about a “sixth mass extinction”. The principal causes are the destruction and fragmentation of the habitats of these species, the overexploitation of ecosystems, the development of invasive species, climate change and pollution and eutrophication (the introduction of nitrogen, phosphorus and other excess nutrients into the environment). Many of these factors are caused by human activities, which have such a strong and rapid influence that the biosphere is unable to adapt to them. What action can we take to halt the trend and prevent ourselves from crossing critical thresholds? Pierre Lopez, Sustainable Construction Project Manager at Bouygues Bâtiment Nord-Est, gives us his point of view on the construction sector.
In Llo, a town in the Pyrenees mountains, France just installed a thermodynamic solar power plant.
Nature provides an endless source of inspiration. Observing nature to inspire technological innovation is the very essence of biomimicry.
For some people, living in the countryside is synonymous with isolation and loneliness. The hamlet of Les Noés in Val-de-Reuil (Eure) proves the contrary: this environmentally friendly eco-neighbourhood promotes the individual and collective well-being of its residents on a daily basis.
