ヒンクリー ポイント C (HPC) 原子力発電所は、ヨーロッパで最大かつ最も技術的に複雑なプロジェクトの 1 つです。

HPC は英国で一世代の間に建設された最初の原子力発電所であり、その建設には高度な熟練労働力と最高の建設およびエンジニアリング ソリューションが必要です。

The HPC Project is located in Somerset, South West England, and will consist of two nuclear reactors capable of generating 3.2GW of low-carbon electricity.

The new power station is being constructed in the same area as the existing Hinkley Point A and B stations. The former has ceased operation for quite some time, while the latter is scheduled to begin decommissioning in 2023.

Battersea Power Station, fully decommissioned almost 40 years ago, is being redeveloped in one of UK’s biggest ever construction projects.

The seven-phased redevelopment venture is estimated to be worth £8bn ($13bn).

The 3rd phase consists in the creation of the so-called ‘Electric Boulevard’, which will include a connection to the Northern Line Extension station, more than 1,300 residential units, a 160-room hotel, retail spaces, restaurants and leisure facilities.

The wide range of concrete reinforcement solutions provided by Dextra was proven to be ideal for this iconic project.

Different ranges of couplers have been supplied for cast-in-situ, precast and repair applications, specifically:

• 100,000 Griptec and Rolltec cast-in-situ couplers
• 30,000 Groutec precast couplers
• 3,000 Unitec bolted couplers

The Cairo Metro project was first launched 30 years ago and since then it revolutionized the transport system of the city.

The first section of Line 3 opened in 2012, and the fourth and last phase of the project is expected to be completed by 2022.

At its final stage, the line will comprise 39 stations:

26 underground stations, 11 elevated stations そして

2 at-grade stations.

Dextra has continuously provided construction solutions to the Cairo Metro project since the construction of Line 2 in the year 2000, delivering since then more than:

• 1,400,000 Bartec rebar couplers
• 7,000 Sonitec sonic tubes
• 60 GFRP Soft-Eyes

The Thomson-East Coast Line is a highly ambitious MRT project in Singapore, interchanging with all existing lines.

With a total length of 43 km and comprising 32 stations, it will be one of the longest driver-less rapid transit lines in the world.

The vast majority of megaprojects suffer from delays that cause both cost overruns and benefit shortfalls: this is why our Soft-Eye GFRP solution has been the preferred choice for the biggest underground transit projects in the world, providing a cost-effective and time-efficient solution.

Cebu-Cordova Link Expressway (CCLEX) is one of the biggest infrastructure projects being undertaken in the Philippines. The project features a combination of a causeway, an 8.5km long cable-stayed toll bridge that will cross the navigable zone of the Cebu Strait, two viaducts and four low height bridges, as well as roadways and pedestrian walkways.

For the reinforcement of the colossal expressway foundations, the contractor CLJV has chosen Dextra’s well-known rebar splicing solution Bartec.

Standard, Bridging, as well as Transition splices in diameters 40 and 50mm have been used with grade 75 bars in the foundations’ piling cages.

Moreover, CLJV opted for Dextra Bartec headed bars to provide better end anchorages in congested areas, a convenient alternative to hooked bars, traditionally used for anchoring.

Also called the Third Bridge Over the Panama Canal, the 2.8-kilometer Atlantic Bridge is one of the world’s longest cable-stayed concrete bridge.

Crossing one of the world’s most crucial shipping routes, the Atlantic Bridge is located near the city of Colón. It is designed not only to let vehicles cross the canal even when the locks are in operation, but also to allow the passage of large container ships, Post-Panamax, with its 75-meter vertical clearance above sea level.

For this iconic project, more than 350,000 Dextra standard Bartec couplers were used for the bridge’s reinforced pile cages, pile caps and pylons by the contractor VINCI Grand Projets. The full-performance Bartec couplers substitute the overlap on rebars of up to #14 (equivalent 43 mm) on grade 80 steel.

Dextra also provided 3 sets of Bartec equipment for on-site bar-end preparation. Machine setup, operator training and maintenance services were done by our local After Sales Service team to guarantee maximum productivity. Moreover, to avoid steel congestion in the bridge’s pile caps, more than 50,000 Headed Bars end anchors were also used.

The Atlantic Bridge is planned to open in early 2019.

Australia’s 8.5-kilometer Forrestfield-Airport Link is a rail service under construction in Perth, Western Australia. It will open in 2020 and allow both locals and tourists to easily commute from the airport to the city and the eastern suburbs.

Aspiring to become a regional hub, Kuwait airport increases its capacity

The Kuwait Airport Expansion project aims to meet the country’s rapid and significant economic growth and satisfy the steadily-rising passenger and cargo flow.

The new Terminal II is designed not only to provide highest comfort to passengers, but also to reflect Kuwait’s rich culture and civilization. When completed, the building will have the form of a symmetrical triangular mark. Passenger capacity of the airport will increase to 25 million in the first phase of the expansion, which would be more than double of what it is currently handling.

Kuwait’s Ministry of Public Works has elaborated very stringent specifications for this landmark project, which requires UK CARES and US ASME certifications from the manufacturer. Rolltec® couplers were therefore a natural choice for the contractor Limak Insaat, as they meet all the client’s requirements in terms of performance and quality, and the client could count on a strong local presence and support from Dextra.

Standard Rolltec® couplers are extensively used for the raft, walls and columns connections of the entire terminal. Furthermore, weldable couplers were delivered for the connection of the ninety precast mega-columns with the steel roof structure.

To support the supply of over 1 million connections, Dextra has deployed fifteen Rolltec® threading machines to site. The project completion date is set in 2020.

Mexico City’s new International Airport was designed by Sir Norman Foster and launched in 2014. It is located to the East of Mexico’s capital and aims to provide the city with a new state-of-the-art air transportation hub. The project consists of an X-shaped terminal with a targeted annual capacity of 68 million passengers, 3 runways, and the control tower.

For this the largest infrastructure project in Latin America, Dextra is supplying Bartec 鉄筋カプラー. These are used in the foundations of the terminal building (contractor ICA), the transport building (contractor Sacyr) and the control tower (contractor Aldesa).

Bartec couplers, often preferred in seismic areas such as Mexico, substitute the overlap on all size ASTM #12 (equivalent 38 mm) rebar. On such large diameters, it is both faster and cheaper to connect bars with couplers rather than traditional overlap splicing.

Dextra is currently providing Mexico Airport with 10 sets of Bartec equipment (a total of 30 machines, with each set delivered in a container). This setup is being supported by our local after-sales team which is training the machine operators and maintaining the equipment to achieve maximum productivity.
