Interview of the month: Nadi Dezert
Nadi Dezert, Sales and Development Director at Bouygues Energies & Services for the Ile-de-France region, talks to us about Cyber Valet Services, a smart parking service.
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.

[Panorama Sustainable Cities] #5 Pontevedra, the car-free city
The city of Pontevedra has adopted a mobility strategy that has brought the use of cars down to the bare minimum. As a result, traffic and pollution levels have dropped dramatically, inhabitants enjoy a new sense of well-being, and the city centre has been given an economic boost.

The Gibraltar site is maintaining momentum!
Since November 2015 more than 100 site workers from Bouygues Energies & Services have been working to build a next-generation thermal power plant in Gibraltar. The aim of the project is to replace three fossil fuel power plants dating from over 30 years ago, which no longer meet European requirements. The biggest challenge in the […]

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.

Developing the city with water: managing resources and coping with the risk of flooding
In France, 1 in 4 people and 1 in 3 jobs are exposed to the risk of flooding, through overflowing watercourses or rising sea levels[1]. In more general terms, floods are a major natural hazard in several regions of the world. These risks are now accentuated by climate change and the increase in extreme weather episodes, including intense rain events in particular. In an urban environment, characterised by a strong increase in soil impermeability, these phenomena promote runoff and associated pollution and lead to congestion and flooding. In addition, urbanisation in flood-prone areas is a major economic and social issue for local communities. To meet these challenges, new approaches are being developed to provide better ways of living with water in cities.

Under what circumstances can digital technology improve resilience at local level?
When applied to local communities, the term “resilience” refers to the ability to function independently of disturbances, whether they are sudden and sudden shocks (e.g. flood, riot, terrorist attack) or chronic stresses creating continuous pressure (e.g. air pollution, ageing infrastructure, antisocial behaviour). While digital technology undoubtedly has a role to play in improving resilience at local level, it also carries vulnerabilities. In what situations can there be a positive relationship between the benefits linked to the use of digital technology, and the environmental impacts and vulnerabilities it causes?
