With a unique architectural design inspired by the crossed scimitar swords of the country’s seal, the Katara Towers are set to become the future hospitality landmark of Doha, Qatar.

These 36-story twin arched towers will consist of a luxurious five-star hotel, the first six-star hotel in the country, and private residences.

A man-made satellite beach-front island will complement the project, housing luxury entertainment and recreational facilities.

For this iconic project, Dextra was entrusted with the reinforcement of the concrete structures using 300,000 Bartec rebar couplers.

The couplers were applied inside foundations, columns and core walls to swiftly connect reinforcement bars of various diameters.

Bartec is a parallel-thread rebar coupler that connects two bars in a 3-step process, including the cold-forged enlargement of the bar before the threading.

This patented process guarantees a very high tensile strength, and a bar-break performance.

The tower’s completion is expected in 2021, becoming a focal point for travelers during the 2022 FIFA World Cup.

MSG Sphere is an under-construction music and entertainment venue being built in Paradise, Nevada, near Las Vegas Strip. The sphere-shaped venue will have a capacity of 18,000 and will feature LED screens inside and outside of the venue.

The equipped indoor spherical digital display panel will spread across the interior of the venue while an outdoor screen display will show what is going on inside. The venue will be built along with new bars, private suites, a museum and retail space.

The 360-feet tall and 516-feet wide sphere is being built on 18 acres off Sands Avenue between Manhattan Street and Koval Lane. Dextra rebar couplers and headed bars have been used to connect and reinforce columns, core walls and beams of the building’s structure.

Dextra’s Bartec rebar couplers are designed to splice either the same or different diameter bars, whether one bar can be rotated, or not. Bartec spliced bars provide full strength in tension, compression and stress reversal applications. The mechanical splicing solution is accredited by major independent regulatory bodies; for example, the American Society of Mechanical Engineers, UK CARES and Bureau Veritas.

Headed bars are also used to replace hooked bars as end anchorages in congested areas to reduce lapping length for beam-column connections. Standard Bartec mechanical anchorages are circular in shape and are attached by threading onto the rebar.

The construction of MSG Sphere is projected to be completed in 2021.

One Bangkok is a new urban development in central Bangkok. This mixed-use project will include offices, retail space, luxury hotels, residences, and cultural and social spaces, with a gross floor area of 1.83 million sq. m. The highlight of the site will be a 430-metre, 90-storey signature tower.

In February 2020, One Bangkok, Co., Ltd, together with CPAC Co., Ltd., and partners: K.C.S. & Associates Co., Ltd., Stonehenge Inter Plc and Italian-Thai Development Corporation Limited completed the largest continuous concrete pouring in Southeast Asia for the mat foundation of one of the first office towers.

The entire process took 33 hours and 15 minutes, with the successful coordination of 547 trucks providing a total 23,725 cubic meters of concrete.

Dextra was behind the connection of 2,200 tons of steel reinforcing mat foundation by supplying 500,000 units of Bartec standard couplers, transition couplers and headed bars.

Bartec standard and transition couplers were applied for various applications which require the joining of reinforcing bars, for example, column to column and beam to column connections.

The transition couplers allowed for the connection of two rebars of different size.

Headed bars were used as an anchor bolt to connect columns to a reinforced concrete foundation. This solution drastically alleviates the congestion of rebars:

Upon completion in 2023, One Bangkok will be a new global landmark destination in the heart of the city.

The Amaryllis is a luxurious residential project with modern amenities located in the premium area of New Delhi, close to the city’s major attractions such as Connaught Place, India Gate, Airport, Rashtrapati Bhawan, and others, making it irresistible to home buyers.

The commitment to completing the project on time was at the heart of this iconic project. As a result, the client was looking to partner with a very dependable coupler agency that has experience executing high-speed projects while delivering a quality product on time.

Thus, Dextra, an ISO 9001: 2015 certified BureauVeritas, is one of the market leaders in the coupler business, having been involved in over 15,000 major construction or industrial projects worldwide and providing unique global experience and expertise.

Almost 1 million pieces of Bartec couplers were delivered to the construction site for the connection of Fe500D, Fe550D and Fe600 grade rebars.

Since the project had stringent schedule and delivery requirements, it was critical to ensure that not only the couplers from Dextra were procured and delivered on site within the specified delivery timeline, but also that the threading equipment installed could cater to an average of 4,000-6,000 ready threads per day.

Furthermore, the main criteria for threading were to use the least amount of equipment possible due to space constraints and to meet the target deliverables. With 3 different size towers connected by a long skywalk, there was an equal amount of pressure on the requirement of threaded rebars to suffice each tower at the same time.

Dextra also supplied Sonitec, an easy-to-assemble and time-saving tube solution, for the CSL (crosshole sonic logging) testing of foundation piles.

The Dextra team in India sent an expert team of supervisors and operators to the site to ensure that the rebar threading and coupler supply were working in tandem. With a strong emphasis on customer satisfaction, all resources were arranged in accordance with the client’s specifications to ensure that there are no delays.

Our goal has always been to provide a quality product to the client, so all quality testing requirements, formalities, and certifications have always been met. Our well-equipped maintenance team was also putting in place the necessary safeguards and provisions to avoid machine breakdowns.

The Oman Botanic Garden is a project located on 423 hectares in Muscat, Oman, aiming to cultivate, study and conserve Oman’s native flora in a sustainable way, and to illustrate the plant-related cultural traditions of the country.

The garden will showcase the native plant species in a series of created habitats, from the dry deserts to the rich monsoon cloud forests.

Dextra supplied sonic tubes for Cross Sonic Logging test to determine the structural integrity and homogeneity of concrete within bored piles, drilled 17-30 meters deep into the ground at the garden building site.

The 20,000 tubes were installed with ease thanks to their enlarged bell-mouth design that allows fast and seamless connections.

Once completed, the Oman Botanic Garden will be one of the largest botanic gardens in the world.

The Yangon’s Landmark Development, also called Yoma Central, is a mixed-used development project located in the center of Yangon, the commercial capital of Myanmar.

This project includes a large retail shopping center, offices towers, hotel and luxury apartments. The whole project wraps around the historic headquarter of the Burma Railway Company, which is being renovated as an hotel of the Peninsula chain.

Dextra delivered its rebar couplers and equipment to the contractor join venture BYMA/Taisei (BYMA is a collaboration between Dragages Singapore & Yoma). More than 200,000 Bartec® couplers are being delivered to the site and will be used for rebar splicing from foundations to super structure.

As of end of 2017, this major construction complex marks actually Dextra’s largest ever construction project in Myanmar and the first to receive Bartec® rebar coupler solution. Bartec® system is well fit for Myanmar, as a Type-2 splice it is recommended for large structures in seismic countries such as Myanmar.

For the first phase of the project, Bartec® rebar couplers 20, 25, 28 and 32mm are being used for foundation works in the D-Walls surrounding the area (vertical connections and horizontal slabs reconnections). Couplers are also used in large concrete beams which will support the Peninsula hotel.

The full project, scheduled for completion in 2021, embodies the modern ambitions and rich history of the fast changing country which is Myanmar.

Queen Sirikit National Convention Center (QSNCC) is a convention center and exhibition hall in Bangkok, Thailand.

The convention center closed for a 15,000-billion-baht renovation on April 26, 2019, after nearly 30 years of hosting various conferences, exhibitions, and international events. It is scheduled to reopen in September 2022 with five times the original venue space.

For this massive renovation, Dextra supplied almost 200,000 Bartec rebar couplers for the connection of d-walls, columns, beams, and core walls.

In November 2022, the convention center will also host the Asia-Pacific Economic Cooperation (APEC) summit.

Yellow Wood 3 is an approximately 40,000-square-meter warehouse and office building in Samut Prakan, Thailand.

Groutec S couplers were used to connect precast concrete columns for easy and fast installation on the site. Groutec S has a smaller outside diameter which makes it slimmer and ideal for slim panels and narrow columns, thus making it useful in smaller scenarios.

Bartec couplers were also installed inside the precast columns as rebar splices.

One Nine Elms is a new mixed-use high-rise project in London, facing the Thames river.

This real estate venture will replace the 44-year-old Market Towers with a 56-storey skyscraper called City Tower and a 42-storeys called River Tower, 18 floors of which will be dedicated to a 173-rooms luxury hotel.

High performance rebar connectors are required in order to reinforce the structure of these two iconic towers: Dextra was entrusted with this job, and provided 70,000 Griptec couplers, well-known for their unrivaled performance in tension, compression, and fatigue conditions.

Supported by high-productivity rebar preparation equipment, Griptec couplers were installed in columns, beams, starter bars for slabs and other parts of the structure.
Furthermore, the homogeneity of concrete within the buildings’ bored piles was tested using the Cross Sonic Logging (CSL) methodology, requiring a transmitter and a receiver to be inserted in parallel water-filled tubes down the pile depth to measure the speed of ultrasonic pulses and ensure the integrity of the foundations.

Dextra’s SONITEC tube facilitated the test thanks to its easy installation into reinforcement cages: 4,000m of ST50 sonic tubes were provided for this project.

Upon completion, anticipated to be in 2022, the City Tower will become one of the tallest residential projects in London and the United Kingdom.

Urban Deca Homes Ortigas is one of the largest residential projects currently developed in the Philippines, involving the construction of 22 residential buildings with 19,000 one- and two-bedroom units on a 13-hectare property in Metro Manila, Philippines.

The developer is expecting to appeal to the young working families of the surrounding areas of Ortigas, Eastwood and Vertis North, offering affordable accommodations starting from as little as 30,000 USD per unit.

Dextra has supplied almost 150,000 Groutec couplers for 20 of the residential buildings: model S25 and S28 are used to connect rebars in load-bearing shear walls.
This typology of mechanical splices is designed to simplify installation of precast concrete elements such as panels or columns.

At the site, connections are made in few seconds by injecting non-shrink grout into the Groutec’s cavity.

The project is expected to be completed by 2022.
