Complejo Icon Siam | ไอคอนสยาม

Complejo Icon Siam | ไอคอนสยาม

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 bartec rebar couplers and 20,000 Bartec Barras con cabeza 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.

Punto de referencia 81, Ciudad Ho Chi Minh

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.

For this project, Dextra is supplying its renowned
bartec 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.

UNA Torre Limassol

UNA Torre Limassol

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

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

For the reinforcement of this landmark building, Dextra delivered its rebar couplers and bar-end preparation machine sets to the contractor J&P and ACC JV, which is 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 rafts and vertical parts of the building.

The completion of this iconic project is scheduled in 2019.

National Bank of Kuwait – New Headquarter

National Bank of Kuwait – New Headquarter

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:

  • 100,000 Bartec couplers were installed for columns reinforcement, construction joints in raft and slab/beam to core wall connections.
  • 35,000 headed bars act as shear studs in raft.
  • 1,500 Unitec bolted couplers were used to extend existing reinforcing bars that were either not threaded or too short for lapping. It is a convenient solution to connect rebars by using a simple pneumatic wrench at the construction site, without the need of any rebar preparation.

    El condominio Plum | พลัมคอนโด

    La estación Plum Central es un proyecto de condominio de 38 pisos, formado por 2 torres y ubicado cerca de la estación elevada de metro Bang Yai, en el noroeste de Bangkok. El edificio residencial albergará 1.013 apartamentos.

    La Fase 1 del proyecto (primera torre) comenzó en septiembre de 2015 y se completará alrededor de marzo de 2018. La construcción a un ritmo rápido es posible gracias al uso de técnicas de hormigón "totalmente prefabricadas".

    Para este proyecto, el propietario del proyecto, Pruksa, gestiona su propia planta de elementos prefabricados.

    Para este proyecto, el objetivo de Pruksa era poder montar rápidamente paneles prefabricados (actuando como muros de corte) para todos los niveles sobre el suelo. Dextra sugirió para ello el uso de acopladores Groutec.

    Acopladores Groutec, montados sobre varilla de Ø25mm previamente preparada con rosca Bartec. Los acopladores, instalados en la parte inferior de cada elemento prefabricado, luego se moldean como parte del elemento del panel de pared prefabricado.

    Después de elevar el elemento al piso superior de la obra, se logra la reconexión con las armaduras salientes mediante la inyección de mortero sin retracción. Cabe señalar que Dextra no proporciona el mortero, que puede obtenerse localmente, lo que genera importantes ahorros. Después de inyectar la lechada, los refuerzos alrededor de cada panel se pueden quitar después de 3 días.

    Primer acto | Torre del segundo acto

    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.

    La torre prefabricada más alta de la India

    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.
