One City Centre (OCC) is a 61-floor office building project in the heart of Bangkok, Thailand.

The building is organized by two masses – the sleek core at the west and the glass office space at the east. The tower is defined by the intersection of these two volumes and wrapped by the diagonal structural system which envelopes the core.

150,000 Bartec rebar couplers and 20,000 headed bars have been installed in the underground sub-structure and superstructure as follow.

The Nanyang Technological University (NTU)’s new ultra-low vibration lab is being constructed.

Since the testing equipment cannot be positioned within a 1.5m radius of any magnetic elements, Dextra GFRP rebars were installed in base slabs and floating slabs as a replacement for steel rebars. GFRP rebars were delivered in a quantity of 3,000 linear meters.

GFRP rebars allow contractors to substitute steel rebar with composite non-corrosive and non-metallic reinforcement. It offers very high tensile performances for a light weight: up to 8 times the performance/weight ratio of steel.

SeaWorld Abu Dhabi is an under-construction marine life theme park and animal research, rescue and rehabilitation center, planned to open in 2023 on Yas Island in Abu Dhabi, United Arab Emirates.

It will be the first SeaWorld park outside of the US, under a license from SeaWorld Parks & Entertainment. The Abu Dhabi-based company Miral is the owner and operator of the project.

Dextra have supplied 400,000 Bartec couplers for the connection and reinforcement of columns, beams, and slabs.

Moreover, 20,000 linear meters of cuttable GFRP (Glass Fiber Reinforcement Polymer) rebar have also been installed in the overlay slabs of the swimming pools, replacing steel rebars as the product of choice.

Thanks to its durability and corrosion-free nature, GFRP is an ideal material when the concrete structure is surrounded by water.

Battersea Power Station was a decommissioned coal-fired power station, located on the south bank of the River Thames, in Nine Elms, Battersea, in the London Borough of Wandsworth.

The power station was one of the world’s largest brick buildings and one of the last major symbols of London’s industrial past.

After the building remained empty for almost 40 years, a redevelopment plan kicked off with the mission to build a new iconic London landmark.

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.

Dextra has been supplying several rebar coupler solutions to the site.

More than 100,000 Griptec and Rolltec cast-in-situ couplers were applied in masonry cells to alleviate the problem of rebar congestion due to long lap length.

Moreover, precast concrete panels reinforced by rebars were used in the building, equipped with 30,000 Groutec couplers for onsite connection of continuation bars.

The panels were easily lifted into place at the construction site: coupler cavities were then filled with non-shrink grouting mortar through the injection holes.

Finally, 3,000 Unitec bolted couplers were installed on rebars for repair works. These couplers were used to replace the damaged reinforcements with new ones and to connect to the finished structure.

The mixed-use community is anticipated to be completed in 2020 and to become a new landmark for locals, tourists and residents.

The Link is a 242-meter-high skyscraper in France, and one of the most recognizable structures in the heart of Europe’s largest business district. The building, located in Paris La Défense, will be the tallest high-rise in the country and a prime example of innovative engineering and cutting-edge technology in the world of architecture.

One of the key factors that sets this building apart from others is the use of Dextra’s Fortec coupler for the reinforcement of its structure. Fortec coupler is a highly advanced and innovative solution for reinforcing concrete structures, and it was used throughout the building to ensure maximum strength and stability.

The building is being constructed with a focus on sustainability and durability. The use of Fortec coupler was an important part of this effort, as it provides a reliable and long-lasting solution for reinforcing concrete structures. The coupler is made of high-strength steel, which makes it extremely durable and able to withstand the harsh weather conditions in the La Défense area.

Fortec coupler also offers a number of benefits over traditional reinforcement methods. For example, it is faster and easier to install than traditional reinforcement methods, which helps to reduce construction time and costs. It also helps to maintain the structure’s integrity even in the event of an earthquake or other natural disaster.

The Link La Défense building is set to be a marvel of modern engineering, and the use of Fortec coupler is a critical component in its design. The coupler’s durability, reliability, and sustainability will ensure that the building remains a prominent structure in the La Défense area for many years to come.

Guggenheim Abu Dhabi is a museum of modern and contemporary art, located in Saadiyat Island cultural district in Abu Dhabi, United Arab Emirates. As this awe-inspiring museum took shape, numerous challenges needed to be overcome, and Dextra provided crucial reinforcements to the structure, ensuring its stability, durability, and overall success. We supplied an astounding 140,000 Bartec couplers, 30,000 RepairGrip couplers, 50 tons of Geotec rock bolts, and 199 sets of DCP anchors, contributing significantly to the construction of this iconic masterpiece.

Strengthening the Structure with Bartec Couplers:

The Guggenheim Abu Dhabi stands tall and proud, thanks to the reinforcement provided by Dextra’s Bartec couplers. With a supply of 140,000 Bartec couplers, Dextra ensured that the concrete reinforcement in the structure remained robust and resilient. These couplers provide a reliable mechanical connection between reinforcing bars, enhancing the overall strength of the structure.

Seamless Rebar Connection with RepairGrip Couplers:

The use of 30,000 RepairGrip couplers helps connect rebars with no prepared threads, ensuring a seamless connection of rebars and minimizing the risk of structural failure.

Stabilizing Rocks with Geotec Rock Bolts:

In addition to the couplers, Dextra provided 50 tons of Geotec rock bolts to stabilize the rocks surrounding the museum. These rock bolts serve as critical anchors, reinforcing the natural formations and enhancing their stability. By utilizing them, the construction team effectively mitigated the geological risks associated with the site, ensuring a secure foundation for the museum.

Retaining the Seawall with DCP Anchors:

The museum, standing gracefully on the shores, required robust seawall retention, and Dextra’s DCP anchors provided the ideal solution. With the supply of 199 sets of DCP anchors, the seawall was reinforced and secured effectively. The anchors offer reliable and efficient retaining solutions for coastal structures, providing stability in the face of dynamic forces such as waves and tides.

Upon completion, it is planned to be the largest of the Guggenheim museums.

Qatar’s General Electricity & Water Corporation (KAHRAMAA) is currently building fresh water reservoirs to store the equivalent of 7 days of Qatar’s national consumption of fresh water at WHO (World Health Organization) standards. The primary reservoirs are located in five different sites in Doha area: Um Baraka, Um Salal, Rawdat Rashid, Abu Nakhla, and Al Thumama.

The first phase of the project involves the construction of 5 mega reservoir sites, and will support the expected water demand at horizon 2026. The second phase includes the construction of 16 additional reservoirs within the five existing mega sites. With a capacity of 3.5 million m3 each, the Reservoirs are among the largest of their kind in the world.

For this project, Dextra Middle East delivered more than 3 million Bartec couplers to the rebar fabricators and contractors involved on the different packages.

Project requirements regarding corrosion protection specify that the complete reinforcement, including couplers, should be epoxy coated. Dextra is therefore delivering all Bartec couplers with epoxy coating, giving them a distinctive green look.

Couplers are used in the raft and columns all over the different reservoirs as a way to reduce steel congestion and generate savings.
