A hub for all genres of music, the City will also serve as a public promenade along the banks of the River Seine. The project is awarded labels in recognition of its environmental excellence: HQE Excellence (High Environmental Quality), BiodiverCity® label and High Quality Usage level 3.

Bouygues Development and Bouygues UK are carrying out one London’s biggest regeneration programmes in Canning Town. The first phase of the project, launched in 2012, focuses on the Hallsville Quarter. It includes the design and construction of 179 private and affordable residential units, a supermarket, a number of shops and 450 car parking spaces. This tranche of the programme also involved the creation of an Energy Centre that will supply the entire neighbourhood. Sequenced in five phases, the project will breathe new life into Canning Town and create a more modern, dynamic and open environment for its residents.

Within the “Pont de Normandie” consortium, Bouygues Travaux Publics built what was when it opened in 1995 the world’s largest cable-stayed bridge in France. It has a total length of 2,141 metres and a span of 856 metres, crossing the River Seine at a height of over 50 metres in order to keep the road traffic flowing without interfering with river traffic heading towards Rouen. In 1995, the 856-metre central span raised the world record for such a span by 80%. For Bouygues Construction, this project provided the opportunity to patent a construction method developed in-house, which proved itself capable of pushing a 700-metre deck up a stepped 6% incline.

As part of the Chrysalis project, Bouygues Bâtiment Ile-de-France was responsible for the full renovation of Paris Zoological Park, which first opened in 1934. Every care has been taken to ensure the well-being of the animals in the new zoo, with in particular the installation of heating from fake rocks and the construction of a tropical greenhouse which is heated to 25°C all year round. Visitors can observe animals living in virtual freedom in five vast bio-zones that include 16 ecosystems. Under the terms of a PFI contract, Bouygues Energies & Services is responsible for maintenance and cleaning for 25 years working alongside the veterinary staff and animal keepers.

A former military fortress in Issy-les-Moulineaux, just outside Paris, has been transformed into an eco-neighbourhood. The challenge was met by Bouygues Bâtiment Ile-de-France, which constructed 1,211 apartments (all with the BBC - Effinergie^® low-energy label), a day-care centre for children and 1,590 m² of shops, all designed with the focus on comfort for residents. On the technological side, a cutting-edge building management system will enable residents to track their energy consumption and control a range of apartment functions from a touch screen or smartphone. This environmentally responsible neighbourhood makes use of renewable energies and it is linked up to Issy Grid^®, the first project for a smart energy network on the scale of a neighbourhood.

On behalf of the Cameroon Ministry of the Economy, Planning and Urban Development, DTP constructed the first 86-kilometre stretch of a road linking Garoua Boulai and Ngaoundéré. The purpose is to reduce the time and cost of transport on the unpaved final section of the Garoua Boulai – Ngaoundéré road network, providing access to the regional corridor linking the port of Douala to the capitals of Chad and the Central African Republic, which do not have sea access. The works consisted of asphalting the road over a 7-metre width and rebuilding five engineering structures.

A new-generation complex entirely devoted to shopping (120 retail outlets) and leisure activities (a 10-screen multiplex cinema), the new Beaugrenelle shopping centre, which has been awarded double HQE® and BREEAM® Very Good certification, took Bouygues Bâtiment Ile-de-France  two and a half years to complete. With a stylish modern design, the centre consists of two precincts joined together by a metal pedestrian footbridge. A special feature of the centre is a 7,000 m² green roof which is home to thousands of plants and birds.

In the Congo, DTP teams are operating one of the largest gold mines in Africa for a period of ten years. In all, 200 million tonnes of rock and earth will be excavated from four pits of more than 700 hectares, for total production of 300 tonnes of gold. To meet this extraordinary challenge, DTP has included as many African-born people as possible in the management team and has set up a specific training programme to train local mechanics in carrying out maintenance operations on earth-moving and mining plant.

In the suburbs of Nantes, Quille Construction was responsible for refurbishing the Sillon de Bretagne, a rent-controlled housing complex which contains 580 apartments. The project also included redeveloping 6,000 m² of offices and building five public amenities. The aim was to guarantee the safety and daily well-being of some 3,000 people living and working in the complex. The programme was designed according to the precepts of sustainable development, with the use of solar energy to produce hot water and measures for offering work to people on social integration schemes.

Located a few minutes from downtown Miami, the Brickell City Centre includes two residential towers with 820 apartments, a hotel, shopping malls, etc. The main blocks are linked by a “climate ribbon”, which is a trellis composed of steel, fabric and glass whose role is to reduce the ambient temperature and protect users from the rain. The project is one of the largest in the United States to be LEED^® registered for Neighbourhood Development.

Roughly 100 kilometres south-west  of Madrid, à Talavera de la Reina, VSL took part in constructing a cable-stay bridge and the approach viaducts over the River Tagus. This spectacular bridge, 318 metres long, is the tallest in Spain. VSL supplied and installed 152 cable stays, the dampers and 890 tonnes of post-tensioning cables for the bridge, which soon became a benchmark for cable-stay bridges.
 

VSL was responsible for producing key elements for the Tran Thi Ly cable-stay bridge, a 731 metre-long, 6-lane structure that crosses the River Han in the city of Da Nang. In particular, the subsidiary supplied the 127 metre-tall central pylon, inclined at an angle of 12°, and installed the cable stays as well as with two bridge bearings with a record-breaking load capacity of 25,000 tonnes each. The new bridge helps relieve very heavy traffic and increase economic in the eastern part of the city.

Bouygues Travaux Publics has designed and built a new 6.7-kilometre highway linking the north and south of Abidjan. Among other structures, the highway includes an interchange and a 6-lane, 1.5-kilometre bridge, named the Henri Konan Bédié Bridge in tribute to the former Ivorian president. The new infrastructure results in a considerable improvement to traffic for the 100,000 vehicles that travel between the north and south of the city every day, and facilitates the transportation of freight to the port.

Bouygues-Thai and Bouygues Energies & Services joined forces to design and construct three photovoltaic solar power plants, located in north-east Thailand, and then to maintain and operate them for 5 years.

The Kai Tak Cruise Terminal is capable of simultaneously berthing two super-liners with 4,000 passengers each. The building, which consists of a series of superposed, landscaped platforms on three levels, has been designed according to the principles of sustainable construction, with a focus on renewable energies: photovoltaic panels, thermal solar panels, etc. A collection system has been developed for rainwater which enables it to be recycled and used for watering the roof, which is entirely green.

Teams from Bouygues Bâtiment Equatorial Guinea, a joint subsidiary of DTP and Bouygues Bâtiment International, have built an 84-kilometre stretch of four-lane motorway linking the port city of Bata, in the west of the country, and Ayak Ntang, in the centre. One of the biggest challenges to overcome was the geotechnical diversity of the terrain (marshes, mangrove swamps and a mountainous region to cross). 2,000 workers and 1,000 items of plant and equipment were required for this imposing project.

Mont Saint-Michel has been imprisoned by sand for over two hundred years. If the sea cannot be brought back to surround the island by 2020, it could disappear altogether. DTP is responsible for the hydraulic engineering works designed to remove sand from the bay: the teams have created 2 channels, one to the east of the island and one to the west. They are also constructing a seawall divider that will channel and accelerate the flow of water released from the dam which will carry away the silt and help rescue Mont Saint-Michel from the sand.

In the framework of a 35-year concession contract, Bouygues Travaux Publics  constructed and now operates a 50-kilometre motorway – the principal one in the country – between the capital city, Kingston, and May Pen, a town in the centre of the island. Highway 2000 has divided journey times for motorists by four. A demanding Quality-Safety-Environment system was in operation during construction to safeguard the environment and natural riches in this protected zone.  

Incorporating lecture theatres, a library and private study spaces, the Rolex Learning Centre, at the heart of the EPFL (Ecole Polytechnique Fédérale de Lausanne) university campus, has been designed to encourage discussions, meetings and work. The “wave-shaped” architectural concept was a major architectural challenge; it consists of two superimposed arched shells with openings, a smaller one and a larger one (the longer one spanning 80 metres). It called for a high degree of technical expertise in modelling and post-tensioning engineering. The challenge was well met by Bouygues Entreprises France-Europe !

In partnership with Bouygues Immobilier Polska, Karmar was responsible for the construction of the head office of Orange Polska. The aim was to facilitate cooperation between the 3,300 employees, who had previously been spread over three separate sites. The head office has been designed as five buildings connected together by an interior gallery. Designed according to the principles of sustainable construction, the site was awarded BREEAM^® Very Good certification at the design stage. The complex is now recognised as one of the most high-performance buildings in Poland.

As one of the main stadiums of the FIFA World Cup 2014 – and most importantly, the venue for the final – the Maracanã stadium in Rio de Janeiro needed to undergo a major renovation. VSL performed a technical feat in lifting the cable-net roof structure.

If you want a magnificent view of the Üetliberg or the Letzigrund stadium, look no further than the Prime Tower in Zurich, the highest building in Switzerland, which is 36 storeys and 126 metres tall. The construction works for this LEED® Gold-certified building, which called for 4,388 glazing units, a third of which allow natural ventilation, were carried out by our Swiss subsidiary, Losinger Marazzi. The innovative design enables all spaces in the building, including the centre of the tower, to be illuminated by daylight, ensuring optimal conditions for the 2,000 people who work in the tower.

In Hong Kong, 2 Bouygues Construction subsidiaries, Bouygues Travaux Publics and Dragages Hong Kong, won a contract to construct the 3.5-kilometre underground stretch of the railway linking Hong Kong to Guangzhou. In this very dense urban environment, numerous networks and deep-laid foundations of buildings made tunnelling operations for the two parallel tunnels, each 9 metres in diameter, a real challenge. During the site work, many measures were taken to minimise the nuisance caused to local residents, in particular the installation of 2 sound baffles, which reduced site noise by 49 decibels.

Imagine a building that generates more electrical energy than it consumes! Bouygues Immobilier designed the Green Office Meudon as a pioneering concept in 2001. Nine years later, Bouygues Energies & Services won the contract to operate the site, in the form of an energy performance contract. To optimise the building’s energy consumption, nine distinct uses of energy are analysed (heating, lighting, air conditioning, etc.). The results are conclusive: after the first year of operation, the building was generating more energy from renewable sources than it was consuming.
