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.
Matching Up has reached the three-year stage and more than ever the Bouygues Construction's open innovation programme aims to generate new ideas within the company, putting Group employees and start-ups in touch in order to design and create new projects together.
Thiebault Clément, Research and Development Manager at Bouygues Construction shares his vision.
Slovenia’s capital is at the forefront in several areas connected with the environment. In particular, it is recognised for having succeeded where many large cities are struggling: in waste management. We look back at 20 years of good decisions, and a combination of political will and local support.

Carbon sinks are essential tools for combating climate change. They raise issues of environmental protection and restoration as well as technological innovation. Some of them are natural, others man-made. But they all act to capture carbon and ultimately reduce air pollution. They have already been discussed in the “Carbon Resilience” trend note; in this article we will look at the prospects for technical development and the absorption capacity of the systems in place.
Originally developed in finance, blockchain is a technological innovation filled with promise that arouses the interest of many players in various sectors. And especially the construction industry! Focus on the blockchain in the sector of construction.
Regulatory pressure is growing on how building and public works waste is processed. The sector produces 70% of waste in France (245 million tonnes, 46 million tonnes of which from the construction sector).
Across the world, nearly 200 m3 of concrete is poured every second. It is one of the most widely used industrial products - even more so than oil, especially in construction. In spite of its advantages in terms of land development, it is one of the major sources of CO2 emissions due to its cement content. How to build greener? About one billion tonnes of CO2 is released each year in the world by the cement industry. In the face of such global challenges and future changes in urbanisation, a revolution in construction methods is beginning. How can the construction sector commit to becoming more carbon-free? Can green building meet this challenge?
(Français) Face à l’augmentation du nombre de seniors dans nos sociétés et à l’évolution de leur style de vie, il est nécessaire de repenser notre vision de l’habitat pour concevoir des logements qui répondent à leurs nouvelles attentes.
