The Group in action
At Bouygues Construction, our ambition is to make the living spaces we design, build and operate increasingly better at meeting the expectations of our customers and users. How are we going to achieve this ambition? By putting innovation at the heart of our model.
With LinkCity, Bouygues Construction develops multiple synergies between its various construction and service specialities, as well as the skills of its partners. It applies this approach systematically from the design phase through to operation, providing an integrated vision of the neighbourhood that combines social connection, environmental performance and connected services to achieve a better quality of life for the end-user.
LinkCity encourages social connection, economic life and moments of sharing. It meets the needs of residents thanks to meeting places, such as offices and hybrid spaces (co-working, fab-labs, concierge services, etc.) that encourage collective usage. Not forgetting the facilities and public spaces that encourage rewarding and community-focused daily life.
LinkCity enables the sustainable neighbourhood to constrict its environmental footprint. The amenities and services it provides encourage eco-citizenship and energy frugality. It applies a circular logic to resource management, through Smart Grids, for example, which create a network for the production, storage and consumption of renewable energies within the neighbourhood. It encourages short supply chains circuits, promotes biodiversity and is moving towards the target of « zero waste ».
The Customer Focus Office
Whether understanding our customers’ vital concerns, ensuring that performance commitments are met sustainably or coordinating relations with stakeholders, LinkCity calls on Bouygues Construction’s wide-ranging expertise to support its customers at each and every step of their neighbourhood project.
LinkCity features multi-modal mobility solutions (shared cars and cycles, charging stations for electric vehicles, communal car parking). It also incorporates infrastructure connectivity to keep pace with new digital usages, through Citybox, for example, a smart street lighting system that connects users to the public space.
What are the aspirations of customers and users?
Bouygues Construction consults its stakeholders to devise innovative and sustainable solutions, particularly through the Sustainable Construction Club, a forum for discussion and reflection on future trends. At Renault’s Batilly plant in eastern France, for instance, Bouygues Energies & Services consulted all those involved in working at the site to devise a plan to shrink its environmental footprint. The result of this collaborative process was a tailor-made lighting solution that takes full account of zones and times of work, guaranteeing energy savings over five years.
What part will
the project play
in its region?
Bouygues Construction’s dedicated Group-wide support structure, Biositiv, ensures that respecting and protecting the environment are central to its considerations at every stage of infrastructure projects. To limit the impact of the route taken by the CD 901 highway north of Beauvais, in northern France on greater-eared bats, a protected species, a 275-metre cut-and-cover tunnel was constructed beneath a forest.
Which partner(s) do we work with?
Because disruptive innovations are often achieved through collective processes, the Group believes in open innovation and works with the best local companies. In Singapore, for instance, Dragages Singapore and BYME, two subsidiaries of Bouygues Bâtiment International, joined forces with Delta Dore and Cryogel, two French SMEs, to provide the Sports Hub complex with an original thermal solution: a continuous 23° C airflow that cools all 55,000 seats in the mega-stadium.
How are costs and schedules kept under control?
BIM (Building Information Modelling) helps the Group keep its promises. A digital model includes all the information relating to a project, including a planning tool and an accurate budget estimate of production costs that is updated with every modification. In Abidjan, Ivory Coast, the Henri Konan Bédié Bridge and all its interfaces were constructed within two years, on schedule, by Bouygues Travaux Publics, DTP and VSL, thanks to expert use of BIM.
What performance is achieved
over the long term?
Operating throughout the whole value chain, the Group focuses on the sustainability and performance of buildings and structures, applying a wide range of expertise, from legal and financial engineering to operation. The City Council offices in Bordeaux were built according to this global approach, which started with the eco-design of the positive-energy building and the anticipation of usages and continued through to the support provided in the operating phase. As a result, the Group has made a commitment that the building will maintain high levels of actual energy performance for 20 years.
Bouygues Energies & Services provides customers with civil drones (UAVs or Unmanned Aerial Vehicles) to help them take and analyse aerial photographs. Reliable and flexible, drones can take on missions ranging from facility inspections with no need to halt operations to topographical studies. The advantages include considerable lower risk for humans and optimisation of the time required to take photos and the associated study costs. This was demonstrated in June 2014 during the inspection of the Sourdun photovoltaic power station, when it only took two hours to cover nine square kilometres of panels and detect the defective solar panels, compared with several days for a standard operation.
To meet the needs of electric mobility, Bouygues Energies & Services has developed the Alizé charging station system for electric vehicles. A turn-key offer, Alizé covers all the phases of the project, from electrical design to operation and maintenance, respecting the standards in force and installations complying with the ZEReady label. It includes innovative user services (SMS when charging is complete, smartphone reservation and availability of stations, etc.). A solution that meets the needs of local authorities and companies, Alizé has been chosen by the Eure-et-Loir département, which plans to install a network of 95 charging stations by 2016, and the La Poste group (the French Post Office), which intends to expand its private network of recharging facilities.
DTP, a Group subsidiary that operates open-cast mines in Africa, uses the technique of lagooning to treat residual oils in water used to wash its site machines. The innovation consists in growing endemic plants such as gamba grass on the polluted substrates and using their capacity to degrade the organic components of the oils. This economical and natural method of phytoremediation, already implemented at the Morila mine in Mali, avoids the need to work the earth to oxygenate it and speed up biodegradation.
With many of our cities getting so congested below ground, innovative methods are needed to make it easier for tunnel boring machines (TBMs) to operate. The Tunnel Dismantling Machine (TDM), which was jointly developed for an undersea tunnel project in Hong Kong by teams from Bouygues Travaux Publics and a partner, CSM Bessac, is intended for dismantling existing tunnels under difficult conditions. It uses the chassis of a traditional TBM, but works in the opposite way: it travels in reverse along an existing tunnel, removing the voussoirs along its path and then progressively pouring concrete to maintain the solidity of the gallery. Homogenous ground is created as a result, in which a new tunnel can be bored.
A Bouygues Bâtiment Ile-de-France innovation, BegreenMap is the first web application that positions certified commercial property and hotels in the Paris region on the same map. It is based on the databases of all the certification organisation in France (HQE, BREEAM, LEED, BBC). Providing advice for customers, the tool enables them to carry out environmental benchmarking of their assets and to define the environmental ambitions that the project should set in respect of the local property market. It’s also a modern and entertaining tool that illustrates Bouygues Bâtiment Ile-de-France’s know-how. Each completed project is positioned on the map, accompanied by a detailed data sheet.
An immersive 3D virtual reality room has been built at Challenger, the Group’s head office. Users are able to immerse themselves completely in a project and to carry out a number of simulations of a building or structure that is yet to be constructed, under realistic conditions. Designed for the purpose of demonstration, the immersive facility, the only one of its kind, is based on 3D digital modelling. It is available to both internal and external populations, promoting collaboration and synergies in technical teams, during project reviews for instance, and helping to convince customers and partners in projects.
Recovering the hydraulic energy generated by lowering a mechanical excavator’s boom is an idea jointly developed by DTP and its equipment supplier, Manu Lorraine. The energy is stored in batteries and then recovered when the driver raises the boom again. This process relieves the load on the pump motor and allows the machine’s engine to be operated at lower revs. In addition, this feature improves the flexibility and speed of the boom’s movement. Benefits include higher productivity, lower fuel consumption, longer service life for the components of the site machines and a general improvement in comfort for the driver.
The aims of a new modular building process developed with our industrial partner, Ossabois, are to reduce costs and delivery times without sacrificing quality and to rely on a renewable resource. The timber panels are prefabricated and fully finished off-site in a workshop, and are then transported and assembled on-site. The Loire-Atlantique département opted for this building system for a new junior high school in Clisson, for which works began in 2014: day after day, approximately 100 very large wooden panels are being transformed into classrooms. The same solution has also been chosen for the Djinn student residence in Le Bourget-du-Lac, in eastern France. Only thirteen months were required to complete the operation, including development.
Erlenapp is a free app, jointly development by qipp (a spin-off of the Swiss Federal Institute of Technology in Zurich) and Losinger Marazzi, the Group’s Swiss subsidiary. The app enables residents of the Erlenmatt West eco-neighbourhood in Basel, Switzerland, to access practical information on their homes, such as their water and energy consumption and details of community events in the neighbourhood, but also to create a social network to meet people, exchange services, etc. The app won an award in the Connected Home category at the Innovation World Cup 2015, organised during the Mobile World Congress in Barcelona.
An articulated robot that changes the cutting disks of tunnel boring machines (TBMs), Telemach reduces the need for human intervention in hazardous environments. There are approximately one hundred cutting disks weighing 350 kg each, and they need to be replaced regularly during the boring process. Jointly developed with Bouygues Energies & Services, this tool forms part of an innovation initiative launched by Bouygues Travaux Publics intended to make work less arduous and to improve the productivity of TBMs. The initiative won the Special Jury Award in the fifth Bouygues Construction Innovation Competition, held in October 2014.
Chun Cheong Yeung
I help to make the impossible possible – that’s my mantra! I am working on the construction of the Tuen Mun-Chek Lap Kok undersea road tunnel. It is being bored 50 metres below the sea, making it the world’s deepest tunnel. Thanks to this amazing experience, I hope that tomorrow I will become an expert tackling the challenges of the most innovative projects!
Everything has sped up in the last five years! Our offers are inspired by a greater tendency to listen, a continuous process of open innovation and real-time pooling of information. Tomorrow, we will be able to imagine original replies to the growing diversity in the way people live and work.
Innovation is my main challenge because our equipment involves more and more integrated software. We have to perfect and constantly share our know-how and knowledge because, in the future, electricians will have to be far more comfortable using software to maintain connected buildings!
