Icon Siam complex, located on the right bank of the Chao Phraya river in the West of Bangkok, is a new multipurpose commercial/residential complex consisting of two highrise buildings and a shopping mall. This new massive project aims to give back its glamour to the banks of the Chao Praya river.

The two towers are expected to reach 280m (SuperLux Tower) and 315m (Magnolia Tower) respectively. The Magnolia Tower will thus be slightly taller than the MahaNakhon Tower, Bangkok’s tallest building since 2015.

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

Dextra engineers performed operator trainings and do preventive maintenance directly on site to guarantee maximum output in thread production.

In total, more than 800,000 バーテック rebar couplers and 20,000 Bartec 頭付きバー are being used in foundations and superstructure in the following applications:

L-shaped dowel bars (wall-slab connections)

This is a typical application used in foundation D-Walls to avoid protruding rebar. it is also used in the superstructure to allow the sliding formwork to climb up without any disturbance

Substitution of hooked bars with end anchors

When the wall reinforcement is especially congested, the use of Headed Bars (also called end anchors) allows to anchor the reinforcement in the wall without the need to produce 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 that case, weldable couplers are the ideal solution: Made of a low-carbon steel, they can be welded easily and allow connection to a threaded rebar.

Landmark 81 is a new highrise tower project located on the bank of the Saigon river in Ho Chi Minh City. The project is owned by Vietnamese company Vingroup.

The tower, whose construction started end of 2014, is expected to reach the height of 462 meters, a new height record in Vietnam. Landmark 81 will the 11th tallest tower building in the world.

このプロジェクトのために、Dextra は有名な
バーテック solution to contractor Coteccons. Bartec solution has been approved by ARUP, owner’s representative consultant, and MACE International, structural consultant.

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

The use of rebar couplers allows the climbing ormwork to move its way up unencumbered as well as connect slabs starting bars in a very productive manner. Those technologies combined with state-of-the-art concrete monitoring allow very fast construction cycles as short as 35 hours per floor.

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

Example of weldable Bartec coupler on beam

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

Concrete works were completed ahead of schedule early 2018.

ONE リマソール タワーは商業ビルであり、キプロス、リマソールの新しいランドマークです。このプロジェクトは、世界クラスの住居、アメニティ、サービスを提供することで、この島を国際的な高級不動産市場で位置づけ、外国投資にとってこの国の魅力を高めることを目的としています。これはキプロスの経済を活性化させると同時に、地元の雇用機会を増やすことにもなるだろう。

このランドマーク的な建物の補強のため、デクストラは鉄筋カプラーとバーエンド準備機械のセットを請負業者の J&P と ACC JV に納入しました。この JV はジョアヌー & パラスケバイデス グループ (J&P) とアラビアン コンストラクション カンパニー (ACC) の合弁会社です。

建物のいかだや垂直部分の鉄筋の接合には 60,000 個を超える Bartec カプラーが使用されました。

この象徴的なプロジェクトの完成は 2019 年に予定されています。

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

The main construction comprises composite concrete and steel, while the cladding on the fins and glass façades is predominantly glass-reinforced concrete.

Dextra took part in reinforcing the concrete structure of the building by providing these solutions:

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

The project consists of two towers called Act One (52 stories) and Act Two (46 stories).

With their prime location, these residential towers offer views of the Dubai Fountain and the Burj Khalifa and they are few minutes away from Dubai Metro and from major attractions like the Dubai Mall and the Souk al Bahar.

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

150,000 Bartec rebar couplers along with rebar preparation machines were delivered to the construction site.

Bartec rebar couplers help speed up the construction with a faster and more convenient way of connecting rebars than the traditional rebar lapping method.

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

The project is scheduled to be completed in November 2020.

This new 4-story retail center has been designed to have the smallest carbon footprint possible, with an innovative optimization of the air-condition load.

It is located in Jebel Ali, Dubai, UAE with an 81,000 sqm floor area and a leasable area for over 100 retail and concept stores.

Dextra Groutec couplers contained in the precast panels made the assembly on site easy and fast. More than 1,100 units of Groutec L 25 and 32mm were delivered.

Groutec is a high-performance precast connection solution which is convenient to set up and fast to install on site by 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. The second phase will include a residential area to create a new lifestyle hub in Dubai.

Galaxy Towers, developed by Aurobindo, is a project to construct 24-storey precast office building in Hyderabad, India.

It will be the tallest office tower in India built with precast technology.

The building comprises of 4 basement floors and 24 upper stories with 1.9 million sq. ft. leasable area, which will include health clubs, food courts, cafés, a business center, ample car parking and a waiting lounge.

The project is expected to be built in half the time of a comparable conventional cast-in-situ construction, illustrating how the precast technology has gained ground thanks to its efficiency.

For this special project, Dextra supplied a critical part of the precast structure: Groutec coupler, a half-grouted sleeve designed for the connection of precast elements and manufactured in compliance with Eurocode 2, BS 8110, ACI 318, IBC, AASHTO & IS 16172.

By installing Groutec couplers into the precast columns and walls at the precast factory, the fast and safe connection of walls or columns is achieved by injecting cementitious non-shrink grout through the inlet into the sleeves at site. 102,000 Groutec couplers have been delivered for this project.

The Galaxy Towers is anticipated to be completed in 2020.
