ICONSIAM, located on the right bank of the Chao Phraya River in western Bangkok, is a multipurpose commercial and residential complex consisting of two high-rise buildings and a shopping mall. This massive development aims to restore the glamour of the Chao Phraya River’s waterfront.

The two towers are expected to reach heights of 280 meters (SuperLux Tower) and 315 meters (Magnolia Tower), respectively. Upon completion, Magnolia Tower will surpass King Power Mahanakhon Tower, which has been Thailand’s tallest building since 2015.

Dextra is supplying Thai-Obayashi (the contractor for the shopping mall structure) and Italian-Thai (the contractor for both towers) with its Bartec rebar splicing solution.

To ensure maximum efficiency in thread production, Dextra engineers have conducted operator training and provided on-site preventive maintenance.

In total, more than 800,000 Bartec rebar couplers and 20,000 Headed Bars are being used in the foundations and superstructure for the following applications:

L-shaped dowel bars (wall-slab connections)

This is a typical application used in foundation diaphragm walls (D-Walls) to avoid protruding rebar. It is also used in the superstructure, allowing the sliding formwork to climb without obstruction.

Substitution of hooked bars with Headed Bars

When the wall reinforcement is especially congested, the use of Headed Bars (also called end anchors) allows for anchoring the reinforcement in the wall without the need for hooks.

Double-ended connection in shear-walls

This solution allows to create a continuity inside the column or wall by bridging two horizontal slabs or beams.

Welded couplers for composite structures

Sometimes, it is necessary to start reinforcement from the steel structure. In such cases, weldable couplers are the ideal solution. Made of low-carbon steel, they can be easily welded and allow connection to a threaded rebar.

Landmark 81 is a high-rise tower project located on the banks of the Saigon River in Ho Chi Minh City. The project is owned by the Vietnamese company Vingroup.

Construction of the tower began at the end of 2014, and it reaches a height of 470 meters to tip, setting a new height record in Vietnam. Landmark 81 is the 17th tallest tower in the world.

For this project, Dextra is supplying its renowned Bartec solution to the contractor Coteccons. The Bartec solution has been approved by ARUP, the owner’s representative consultant, and MACE International, the structural consultant.

In total, 250,000 Bartec couplers will be used for vertical rebar connections in the core wall and columns, as well as for horizontal applications such as core wall-to-beam and core wall-to-slab connections.

The use of rebar couplers allows the climbing formwork to progress unencumbered, while also enabling efficient connection of slab starter bars. These technologies, combined with state-of-the-art concrete monitoring, facilitate extremely fast construction cycles—as short as 35 hours per floor.

For composite applications (steel columns to beams), Dextra has also supplied 20,000 weldable couplers.

The fast-paced construction site is supported by three sets of Dextra Bartec bar-end preparation equipment, installed directly on site. The equipment is maintained by Dextra and operated by Dextra’s distributor in Vietnam, Lotus Greentech.

ONE Limassol Tower is a commercial building and a new landmark in Limassol, Cyprus. The project aims to position the island in the international luxury property market, enhancing its attractiveness for foreign investment by offering world-class residences, amenities, and services. This will also boost Cyprus’ economy while increasing local employment opportunities.

At 170 meters tall, with a total of 33 storeys, ONE Limassol Tower is the tallest seafront residential project in Europe. The building will feature 83 luxurious apartments, including a three-storey penthouse.

To reinforce this landmark building, Dextra supplied its rebar couplers and bar-end preparation machine sets to the contractor J&P and ACC JV, a joint venture between Joannou & Paraskevaides Group (J&P) and Arabian Construction Company (ACC).

More than 60,000 Bartec couplers were used for rebar splicing in the rafts and vertical structural elements of the building.

The new headquarters building of the National Bank of Kuwait is a 300m-tall tower with a total floor area of 127,000m². Its design, inspired by pearl shells, is located in the heart of Kuwait City’s financial district.

The main structure consists of composite concrete and steel, while the cladding on the fins and façades is predominantly glass-reinforced concrete.

Dextra contributed to reinforcing the building’s concrete structure by providing the following solutions:

• 100,000 Bartec couplers were installed for column reinforcement, construction joints in the raft, and slab/beam-to-core wall connections.
• 35,000 headed bars acted as shear studs in the raft.
• 1,500 Unitec bolted couplers were used to extend existing reinforcing bars that were either unthreaded or too short for lapping. This convenient solution allows for rebar connections using a simple pneumatic wrench on-site, eliminating the need for rebar preparation.

Act One | Act Two Tower is a premium residential project in the Opera District of Downtown Dubai.

The development consists of two towers: Act One (52 stories) and Act Two (46 stories).

With their prime location, these residential towers offer stunning views of the Dubai Fountain and the Burj Khalifa. They are just a few minutes away from the Dubai Metro and major attractions such as the Dubai Mall and Souk Al Bahar.

For this exceptional residential project, Dextra was entrusted with reinforcing the buildings’ structures, including raft foundations, columns, slabs, and construction joints.

A total of 150,000 Bartec rebar couplers, along with rebar preparation machines, were supplied to the construction site.

Bartec rebar couplers accelerate construction by providing a faster and more efficient way of connecting rebars compared to the traditional lapping method.

The thread on the rebar can be extended from a half-coupler to a full-coupler length, allowing the connection to be completed without rotating the bar.

Big Box Retail is a new four-story retail center designed to have the smallest possible carbon footprint, featuring an innovative optimization of the air-conditioning load.

Located in Jebel Ali, Dubai, UAE, the center spans 81,000 square meters and offers a leasable area for over 100 retail and concept stores.

Dextra’s Groutec couplers, integrated into the precast panels, made on-site assembly quick and efficient. More than 1,100 units of Groutec L in 25mm and 32mm sizes were supplied.

Groutec is a high-performance precast connection solution that is easy to set up and fast to install on-site using grout injection. It supports the connection of precast concrete columns, panels, and beams.

The first phase of the retail center is set for completion in 2019, while the second phase will introduce a residential area, creating a new lifestyle hub in Dubai.

The Floresta Gardens project involves the construction of towers within The Pearl Qatar.

The project includes the construction of mid-rise residential towers and villas within three gated villa communities, along with a 2,452-square-meter retail center. The precinct features a gross floor area of 267,471 square meters, 145,967 square meters of developable land, and 5,000 residential units.

In the precast construction of the towers, Dextra’s Groutec couplers played a significant role. Over 30,000 Groutec L couplers, ranging in size from 20 mm to 40 mm, were embedded in columns for vertical connections on-site.

Groutec precast couplers provide an innovative solution for fast and easy connections of precast concrete elements. They are widely used in residential and commercial construction projects worldwide.
