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.
Every day, concrete endures attacks of all kinds (carbon dioxide from the air, chlorides, etc.). These aggressive substances corrode the concrete's metal reinforcements and cause deterioration. Unavoidable? Yes. Disastrous? No – not if you know exactly when to do renovation work.
Interview with Stéphane Schaeffer, Planning Manager and head of lean deployment, BYMARO.
In late 2020, Bouygues Construction, Banque des Territoires and Chronos (an urban innovation consulting firm), with the support of France Ville Durable, held a retreat to discuss the topic of setting up a regional resilience programme. Using an array of assessment tools and regional initiatives, the attendees identified the key factors needed to formalise a regional resilience programme. France Ville Durable, Cerema, AEME, the French High Committee for National Resilience, the Paris Région Institute and the Grenoble Urban Planning Agency spoke of the dedication shown by those involved in this subject, and animated discussions on how to formalise the concept of regional resilience.
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?
The Matching Up Challenge is back! This call for innovative projects ‘matches’ start-ups with Group employees. What's it like working with a start-up? Yolaine Perrot, Lean Management Director at Bouygues Construction and Xavier Motsch, the founder of LeanCo, tell us all about it.
Urban overheating is becoming a recurring phenomenon, resulting from the cumulative effect of climate change and the Urban Heat Island (UHI) phenomenon. Climate change is leading to an increase in the intensity and duration of heat waves (hot air masses causing high temperatures for several consecutive days) in different parts of the world. These meteorological phenomena themselves reinforce the UHI, a climatic effect causing a difference in temperature between the centre of urban areas and outlying or natural areas, which can be greater than 10 °C during heat waves. The effect is even more pronounced at night, when the heat stored by artificialised land and buildings is released into the air, keeping the temperature high. Faced with the various consequences (social, environmental, economic) and climate projections, local and regional authorities are now faced with the need to adapt their cities in order to combat this phenomenon. Below is an overview of the challenges and solutions.
Formerly known as Tunnel Lab, the Lab TP is now expanding its range of innovations. Nicolas Braud, Director of Lab TP, Innovation, Digital and Big Data at Bouygues Travaux Publics, presents the development of his missions with his team.
