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 Liantang tunnelling project entered a new chapter on 1st March with the breakthrough of the southbound tube’s Tunnel Boring Machine (TBM) section by Hong Kong’s largest dual-mode Earth Pressure Balanced (EPB) TBM. A milestone in this major project for Chinese regional planning.
In our town and cities, where vegetation is becoming increasingly scarce, how can we absorb carbon dioxide, claimed by scientists to be the number one cause of climate change? Imagine a material that could grow like trees by absorbing carbon dioxide!
We are what we eat, but we are also what we breath: more than 15 kg of air every day! And most of that air quality comes from confined spaces. We spend more than 80% of our time inside with many pollutants. New constructions could well bring a breath of fresh air…
This 5,400 metre-long sea viaduct, which will connect Saint-Denis (the capital of Reunion Island) to La Grande Chaloupe, is a major component of the New Coastal Road. The aim is to replace the current road along the coast between Saint-Denis and La Possession, which is dangerously exposed to the risk of rock falls and submersion […]
With environmental issues changing sites, Hésus offers construction industry professionals the chance to improve the management of excavated material using recovery solutions, combined with logistical expertise. This collaboration is already under way on Brézillon Environnement’s construction sites!
The concept of “sponge cities”, launched by the Chinese government almost ten years ago, presents a way to mitigate the effects of floods in large cities and to recreate the natural water cycle in urban areas. The idea is to optimise overall management, from recovery to use. These adaptations for better resilience are currently taking place in 30 cities.
“Nothing is lost, nothing is created, everything is transformed.” These famous words from Lavoisier became the motto of Brézillon which opened a contaminated soil transit, sorting and recovery platform in February.
April 2018 – Cédric Vilani, a deputy of the La République en marche (LREM) party in Essonne, publishes a reference document on artificial intelligence. It namely gives a few indications on the consequences of artificial intelligence development on the construction sector. At Bouygues Construction, are we ready?
You may have heard of it without really understanding what it was all about, or perhaps you simply want to know more. Whatever your level of familiarity with Building Information Modeling, watch these informative videos to find out more about one of the major changes in our industry.
