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.

      • Digital technology for convergence between buildings and mobility

        Eleven tonnes of CO2 per year: this is the carbon footprint of a household in France. Given that housing and mobility contribute equally to more than half of all greenhouse gas emissions, it is vitally important to combine the efforts of the construction and mobility sectors. Working within the SBA (Smart Buildings Alliance), the R2S 4 Mobility commission, coordinated by Claude Ricaud – a consultant at the GIMELEC consortium of companies in the electro-digital sector – is striving to achieve this goal. 

      • What added value does AI bring to the construction, real estate and urban planning industries?

        Artificial intelligence (AI) is changing the way industry professionals approach their day-to-day work. This is for good reason as the potential benefits of AI are numerous, from reducing costs to improved project quality and better management of resources. In which areas, however, is it already being used reliably? How can its use save time for professionals? Can AI and humans work together without making mistakes? What could be the benefits of using this type of tool? What better way to answer these questions than to interview an industry professional (Thiebault Clément, R&D Director at Bouygues Construction) and a form of artificial intelligence which has been in the news for several weeks (ChatGPT*).

      • How can we develop and build in the context of “Zero net artificialisation” ?

        23,000 hectares: this is the average annual area of natural, agricultural or forest land reallocated to urbanisation in France over recent years, the equivalent of 2.2 times the area of Paris, 33,000 football pitches or 19 million parking spaces. A figure which makes France one of the worst European students with regard to restraining real-estate development. The impact on biodiversity and CO2 emissions are such that there is an urgent need to hold back this effect. Although the target of Zero net artificialisation (ZAN) was written into the national biodiversity plan in July 2018, the strategy, method and means of bringing this into reality remains to be specified. Likewise the search for a denser, viable and liveable urban development model in large conurbations as well as town centres and small and medium-sized towns.
