Business Garden Bucharest is a modern mixed used class A office complex. It features retail spaces, pairing with commercial and public services on the ground level. The name Business Garden stems from its integrated spacious green area, a garden connecting the buildings with designated recreation spaces. Generous lawn area, pedestrian pathways, and benches with free Wi-Fi are provided to invite the office goers to work or take a refreshing break outside. The complex is LEED Platinum pre-certified. To support the tenant’s everyday life needs of their employees, Business Garden Bucharest’s offices are designed to have efficient layout, built with high quality finishes and sustainable solutions that are in line with LEED Platinum green certifications.

For this project, Dextra was involved in the supply of its Fortec rebar coupler solution. The Fortec solution is made up of a standard rebar coupler that can be utilize as both standard and position splices connecting two rebar ends that have been previously enlarged and threaded. Fortec is especially suitable for seismic environment construction, which is the case of buildings in the Bucharest area.

Fortec couplers have been used to provide superstructure vertical connections. Fortec couplers are relatively compact and can help to reduce the congestion created from rebar lapping. Fortec couplers also provided temporary opening, allowing movement of the workers and equipment around the reinforcement. Before casting, the continuation bars are simply connecting to the couplers, filling the temporary opening gap.

London Wall Place is large a double tower office development in London built close to the Roman City Wall historical monument.

For this project, Dextra offered contractor Byrne Bros and main consultant WSP a technical solution for the fast installation of precast wall panels.

The concept was to install Groutec couplers in each panel reinforcement, at the bottom of the vertical bars previously prepared with Rolltec thread system, available in the UK through our distributor network.

After bracing the precast panel in its final position, non-shrink grout is injected into the cavity of the coupler, in order to create the rebar connection. Groutec is not reliant on a specific type of grout. Rather, several different brands of grout can be used, facilitating local scouring and helping to keep costs low. The bracing around the panel is then removed after the grout has achieve a prescribed strength.

After straightening and bracing of the precast panel, non-shrink grout is inserted into the cavity by injection. Dextra does not supply grout as Groutec is by design compatible with several brands that can be sourced locally, generating savings and easing project management.After injection, the bracing around the precast panel may then be removed after only 3 days.

The use of Groutec for precast panel is a time-saving and economical way to quickly take advantage of the precast technology. For similar application video, please check The Plum Central Station project page.

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 بارتيك rebar couplers and 20,000 Bartec قضبان الرأس 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.

For this project, Dextra is supplying its renowned
بارتيك 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.

المبنى الرئيسي الجديد لبنك الكويت الوطني هو برج يبلغ ارتفاعه 300 متر ويغطي مساحة أرضية إجمالية تبلغ 127000 متر مربع بمفهوم تصميمي مستوحى من أصداف اللؤلؤ ويقع في قلب الحي المالي بمدينة الكويت.

يتكون البناء الرئيسي من الخرسانة المركبة والفولاذ، في حين أن الكسوة على الزعانف والواجهات الزجاجية هي في الغالب من الخرسانة المسلحة بالزجاج.

شاركت دكسترا في تعزيز الهيكل الخرساني للمبنى من خلال تقديم هذه الحلول:

برج وان ليماسول هو مبنى تجاري ومعلم جديد في ليماسول، قبرص. ويهدف المشروع إلى وضع الجزيرة في سوق العقارات الفاخرة الدولية، وتعزيز جاذبية البلاد للاستثمار الأجنبي من خلال تقديم أماكن إقامة ووسائل راحة وخدمات ذات مستوى عالمي. سيؤدي هذا أيضًا إلى تعزيز الاقتصاد القبرصي، مع زيادة فرص العمل المحلية.

على ارتفاع 170 مترًا فوق سطح الأرض ويتكون من 33 طابقًا، يعد برج ONE Limassol أطول مشروع سكني على الواجهة البحرية في أوروبا. وسيحتوي المبنى على 83 شقة فاخرة، بما في ذلك شقة بنتهاوس مكونة من ثلاثة طوابق.

من أجل تعزيز هذا المبنى التاريخي، قامت شركة Dextra بتسليم قارنات حديد التسليح ومجموعات آلات إعداد نهاية القضبان إلى المقاول J&P وACC JV، وهو مشروع مشترك بين مجموعة Joannou & Paraskevaides (J&P) وشركة الإنشاءات العربية (ACC).

تم استخدام أكثر من 60.000 قارنة توصيل من Bartec لربط حديد التسليح في الطوافات والأجزاء الرأسية من المبنى.

ومن المقرر الانتهاء من هذا المشروع الشهير في عام 2019.
