Hong Kong-Zhuhai-Macau: a bridge over the Pacific

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 RE 2020: what are the changes for housing in the future on the French market?

        The arrival of the French regulation RE 2020 brings the goal of decarbonised cities even closer. The major new feature of this climate and energy package consists in not only considering energy savings at the level of every new construction, but also in including the carbon footprint in the various impact measures linked to these sites. This approach will not only allow us to transform our construction practices, but will also transform the way in which inhabitants in the future could take ownership of and live in their homes and the wider local area. So, what changes are coming? What are the possible impacts for the construction industry right now? And how will the way in which we live have to change?

      • The latest developments in low-carbon concrete

        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?

      • What role can bicycles play in the cities of the future?

        The COVID-19 pandemic, through the urban planning initiative of "coronavirus bike lanes", has highlighted the return of the bicycle to the city. In reality, this comeback has been under way for many years, though it did get a recent boost. What are the causes? What are the consequences on urban planning today? What will bicycles in cities look like ?

      • 3D printing, a technology to serve humans and human art

        With the aim of reducing occupational health risks on work sites, improving productivity and producing complex items, 3D printing, while still in its experimental stage, is taking the building sector into an industrialisation process that will result in some exceptional achievements. Technology to serve US, not vice-versa.
