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

The building is composed of two masses—the sleek core on the west and the glass office space on the east. The tower is defined by the intersection of these two volumes and is wrapped by a diagonal structural system that envelops the core.

A total of 150,000 Bartec rebar couplers and 20,000 headed bars have been installed in the underground substructure and superstructure as follows.

Underground sub-structure:

• Applied in diaphragm walls.
• To reinforce steel rebar in the mat foundation.
• To simplify the top-down construction process.
• To facilitate the concrete pouring stage of the mat foundation (headed bars).

Superstructure:

• Applied in core walls.
• Used as a dowel for starter bars.
• To connect columns and columns to beams.
• To facilitate the construction work in temporary openings.

The project is scheduled for completion in the last quarter of 2022.

Battersea Power Station was a decommissioned coal-fired power station located on the south bank of the River Thames in Nine Elms, Battersea, within the London Borough of Wandsworth. It was one of the world’s largest brick buildings and a lasting symbol of London’s industrial past.

After remaining empty for nearly 40 years, a redevelopment plan was launched with the mission of creating a new iconic London landmark.

The third phase of the redevelopment consists of the development 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 supplied several rebar coupler solutions to the site. More than 100,000 Griptec and Rolltec cast-in-situ couplers were installed in masonry cells to alleviate rebar congestion caused by long lap lengths.

Additionally, precast concrete panels reinforced with rebars were used in the building, incorporating 30,000 Groutec couplers for onsite connection of continuation bars. The panels were easily lifted into place at the construction site, where the 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 work. These couplers were used to replace damaged reinforcements with new ones and to connect them to the finished structure.

The mixed-use community was expected to be completed in 2020, becoming a new landmark for locals, tourists, and residents alike.

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 constructing fresh water reservoirs to store the equivalent of seven days’ worth of Qatar’s national fresh water consumption at World Health Organization (WHO) standards. The primary reservoirs are located at five sites in the Doha area: Um Baraka, Um Salal, Rawdat Rashid, Abu Nakhla, and Al Thumama.

The first phase of the project involves the construction of five mega reservoir sites to support the expected water demand by 2026. The second phase includes the addition of 16 more reservoirs within the five existing mega sites. With a capacity of 3.5 million m³ each, these reservoirs are among the largest of their kind in the world.

For this project, Dextra Middle East supplied more than 3 million Bartec couplers to the rebar fabricators and contractors involved in the various project packages.

Project specifications for corrosion protection require that the entire reinforcement system, including couplers, be epoxy-coated. Therefore, Dextra is supplying all Bartec couplers with epoxy coating, giving them a distinctive green appearance.

Couplers are used in the raft and columns across the different reservoirs to reduce steel congestion and generate cost savings.
