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. They will enable energy producer Soleq Solar Thailand to generate approximately 45 gigawatt-hours of renewable energy per year, equivalent to the annual consumption of a city of 90,000 people.  

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. The operation was carried out in two phases using 60 lifting points, making it possible to lift it into place in a single piece. Some 85 tonnes of mini-cables and 270 tonnes of equipment were delivered to Brazil.  

The Yyldyz Hotel, a 5-star luxury hotel located in Ashgabat, capital of Turkmenistan, took Bouygues Bâtiment International  24 months to complete.

Prague now possesses the most modern shopping centre in the country. Designed according to the principles of sustainable construction, the shopping centre has been awarded BREEAM^® certification. To achieve certification, our subsidiary opted for such solutions as storing and reusing stormwater and using triple glazing for the glazed walkways.

Bouygues Travaux Publics handled the construction of the nuclear island for the Olkiluoto EPR reactor in Finland, in addition to the backup and storage buildings. The biggest issue was ensuring the safety of the site. This colossal project has created a veritable fortress, 50 m in diameter, with an external shell made from reinforced concrete, and an internal containment structure made from 1.30 m of pre-stressed concrete lined with a metallic "skin". In total, 144,000 m³ of concrete were poured, much of it going toward the external shells which protect the power station from outside assaults, including the impact of an aeroplane.

Bouygues Construction handled the development of the brand new regional hospital in Orléans. In order to provide more comfort to patients, the La Source hospital centre now groups the two Orléans university hospital facilities, expanding its capacity by 29 %. As the number-one HQE®-certified regional hospital, the centre will relies more on alternative sources of energy, bioclimatic architecture and extremely energy-efficient equipment, such as triple-pane windows with integrated blinds.

Constructed in 1969, the Marquette-Lez-Lille water treatment facility was no longer in compliance with European regulations. The new facility, designed and constructed by Norpac, is among the ten largest in France, and treats the industrial waste water of 37 towns and villages. More efficient, modern and compact, the facility is a model of sustainable construction, with buildings integrated into the landscape, systems that minimise sound and odour pollution, and HYBAS™ technology for ensuring that waste water treatment is entirely organic.

Bouygues Travaux Publics, Quille Construction and DTP  handled the civil engineering for EDF's EPR reactor in Flamanville, a third-generation European nuclear reactor.

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.

With monumental gates and carved ceilings, this sublime luxury hotel complex, built as a turnkey project by Bouygues Bâtiment International, has been designed as a typical Moroccan medina and is complete with traditional Moroccan handcrafted finishes.
