Interview of the month: Julien Ciacci
Julien Ciacci, a Rénovation Privée Project Manager, is here to talk to us about Newlife – a new company that aims to reuse and repurpose construction site materials.
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.

Still engaged with change after ninety years
Although the HLM movement will soon be a hundred years old, it is still calmly and determinedly addressing the challenges it must face: providing homes, of course, but also accommodating changes in society. Energy transition, climate change, regional sustainability, and the shift to digitalisation are all taken into account.

When 3D printing meets plastic recycling …
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?

When cities overheat
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.

The station of the future – challenges and prospects
Providing a link between here and elsewhere, stations constitute an essential centrality for cities of the future. At the heart of major disruptions on a number of levels, stations are the subject of numerous innovations in areas that go beyond the field of mobility. After an open and collaborative approach to mobility, which resulted in the trend book “Cities & mobility, a reinvention of proximity”, we are now focusing on the outlook for the railway station of the future.
