The Key Rama 3 is a 484-unit high-rise condominium by Land & Houses, offering unit sizes ranging from 29 to 61 square meters. The project is located near the Chao Phraya River on Rama 3 Road, approximately 12 km from Charoen Krung Intersection to Na Ranong Junction in Klong Toei, Bangkok, Thailand.

The condominium is constructed entirely from precast concrete, with no cast-in-place concrete used for its main structural elements.

This construction method required fewer workers and reduced the use of materials such as rebars and concrete on-site, leading to a shorter construction period and fewer complaints from the neighboring community regarding noise and waste.

Grouted mechanical sleeves were used to connect the precast elements, with Dextra Groutec couplers playing a key role in the process. These couplers were installed inside the shear walls and bearing walls.

“The half-grouted mechanism of Groutec L and Groutec S sleeves, which feature a threaded end on one side, ensured accuracy and minimized mistakes during the grouting process,” said Mr. Janeboon Leepipatnavit, Project Director of Taveeporn Technology Co., Ltd., the project’s contractor.

Mr. Janeboon further stated that Dextra is a reliable company with its own facilities in Thailand, providing immediate support when required.

King Salman Energy Park (SPARK) is a new industrial city currently under construction between Dammam and Al-Ahsa in the Eastern Province of Saudi Arabia.

The project aims to meet the country’s growing demand for energy-related products and services, including exploration, production, refining, petrochemicals, conventional power, water production and treatment, and drilling.

Upon completion of the first phase in 2021, SPARK will be divided into five main zones: an industrial zone, a dry port and logistics zone, a business district, training centers and residential compounds, and commercial areas.

Dextra supplied approximately 700,000 ASTEC GFRP (Glass Fibre Reinforced Polymer) rebars, model GR45P, in both straight and bent shapes for buildings and sidewalks.

ASTEC GFRP GR45P rebar provides a modulus of elasticity of 45 GPa and tensile strength in accordance with ASTM 7205-06. It serves as a strengthening material for both new and existing structures.

Upon the anticipated completion of the third phase in 2035, SPARK will span 50 square kilometers and is expected to create 100,000 jobs.

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

These 36-story twin arched towers will feature a luxurious five-star hotel, the country’s first six-star hotel, and private residences. A man-made beachfront satellite island will complement the project, offering luxury entertainment and recreational facilities.

For this iconic development, Dextra was entrusted with reinforcing the concrete structures using 300,000 Bartec rebar couplers. The couplers were installed in the foundations, columns, and core walls to efficiently connect reinforcement bars of various diameters.

Bartec is a parallel-thread rebar coupler that connects two bars through a three-step process, including cold-forged bar-end enlargement before threading. This patented process ensures exceptional tensile strength and a bar-break performance.

The towers are expected to be completed in 2021, becoming a focal point for travelers during the 2022 FIFA World Cup.

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

The indoor spherical digital display panel will span the entire interior of the venue, while an exterior screen will broadcast live visuals from inside. The venue will also include new bars, private suites, a museum, and retail space.

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

Bartec rebar couplers are designed to splice rebars of the same or different diameters, whether or not one bar can be rotated. Bartec-spliced bars provide full strength in tension, compression, and stress reversal applications. The mechanical splicing solution is accredited by major independent regulatory bodies, including 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, reducing lap lengths for beam-column connections. Standard mechanical anchorages are circular in shape and are attached by threading onto the rebar.

The construction of MSG Sphere is expected 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 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 2024, One Bangkok will be a new global landmark destination in the heart of the city.

The Amaryllis is a luxurious residential project featuring modern amenities in a prime area of New Delhi. Its strategic location near major city landmarks such as Connaught Place, India Gate, the airport, and Rashtrapati Bhawan makes it highly desirable for homebuyers.

Timely completion was a key priority for this iconic project. As a result, the client sought a reliable coupler supplier with experience in high-speed construction while maintaining product quality and on-time delivery.

Dextra, an ISO 9001:2015-certified company by Bureau Veritas, is a market leader in the coupler industry. With a track record of over 15,000 major construction and industrial projects worldwide, Dextra brings extensive global experience and expertise to the project.

Nearly 1 million Bartec couplers were supplied to the construction site to connect Fe500D, Fe550D, and Fe600 grade rebars.

Given the project’s stringent schedule and delivery requirements, it was crucial not only to procure and deliver the couplers within the specified timeline but also to ensure that the threading equipment could process an average of 4,000–6,000 ready threads per day.

Additionally, due to space constraints, the threading process had to be optimized to use the least amount of equipment while still meeting production targets. With three different towers connected by a long skywalk, there was constant pressure to ensure a steady supply of threaded rebars for all towers simultaneously.

Dextra also supplied Sonitec, a user-friendly and time-efficient tube solution, for crosshole sonic logging (CSL) testing of foundation piles.

To ensure seamless execution, Dextra India deployed an expert team of supervisors and operators to oversee rebar threading and coupler installation. With a strong commitment to customer satisfaction, all resources were aligned with the client’s specifications to prevent delays.

Dextra’s commitment to quality remains paramount. All testing requirements, formalities, and certifications were meticulously adhered to, while a well-equipped maintenance team implemented safeguards to prevent machine breakdowns.

The garden will feature native plant species in a series of recreated habitats, ranging from arid deserts to lush monsoon cloud forests.

Dextra supplied Sonitec for crosshole sonic logging (CSL) testing to assess the structural integrity and homogeneity of concrete within bored piles, which were drilled 17-30 meters deep at the garden’s building site.

A total of 20,000 tubes were installed with ease, thanks to their enlarged bell-mouth design, which enables fast and seamless connections.

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

Yangon’s Landmark Development, also known as Yoma Central, is a mixed-use development project located in the heart of Yangon, the commercial capital of Myanmar.

This project features a large retail shopping center, office towers, a hotel, and luxury apartments. The entire development is built around the historic headquarters of the Burma Railway Company, which is being renovated into a Peninsula hotel.

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

As of the end of 2017, this major construction project marked Dextra’s largest-ever undertaking in Myanmar and the first in the country to utilize the Bartec rebar coupler solution. The Bartec system is well-suited for Myanmar, as its Type-2 splice is recommended for large structures in seismic regions.

In the first phase of the project, Bartec rebar couplers in 20mm, 25mm, 28mm, and 32mm diameters are being used for foundation works, particularly in the diaphragm walls surrounding the area (for vertical connections and horizontal slab reconnections). Couplers are also being installed in large concrete beams that will support the Peninsula hotel.

Scheduled for completion in 2021, this development embodies both the modern ambitions and rich history of Myanmar, a country undergoing rapid transformation.
