International Commerce Centre (ICC), Hong Kong

The International Commerce Centre (ICC) is a landmark skyscraper in Hong Kong, located in West Kowloon. This commercial building stands 484 meters high and features 108 floors. To this day, it remains the tallest building in Hong Kong and is the 13th tallest building in the world.

การมีส่วนสนับสนุนของเดกซ์ตร้า

Vertical reinforcement is a crucial factor for skyscrapers of this height. Consultant ARUP and contractor Sanfield selected Dextra for the splicing of reinforcement throughout the structure. Notably, both stakeholders had previously worked with Dextra on the Two IFC project, another iconic 400m+ skyscraper completed a few years earlier.

For this project, Dextra supplied more than 800,000 ฟอร์เทค rebar couplers, which were used primarily for vertical connections, especially in columns.

Additionally, rebar couplers provided connection points for second-phase rebar reconnection, typically between:

  • Columns and slabs
  • Columns and beams

In these applications, rebar couplers were aligned horizontally and cast in concrete. The reconnection process was performed later by simply screwing in second-stage rebar.

Preferred Splicing Solution in Hong Kong

ฟอร์เทค is the preferred reinforcement splicing solution among contractors in Hong Kong, as it is officially recommended in the Hong Kong Building Material List.

Dextra also operates its own rebar threading workshop in Hong Kong, providing rebar preparation services to its customers.

Marina Bay Sands, Singapore

Marina Bay Sands, Singapore

Marina Bay Sands is a spectacular resort featuring more than 2,500 rooms, a casino, numerous restaurants, and a distinctive sky garden. The project was completed and opened to the public in 2010.

Between 2007 and 2008, Dextra supplied บาร์เทค การเสริมแรง ผลิตภัณฑ์สำหรับการเชื่อมต่อเหล็ก and Sonitec tubes for the project.

บาร์เทค rebar couplers were used in the foundations for ผนังไดอะแฟรม, addressing a dual challenge:

  • Vertical connections: Rebar couplers were used to connect D-Wall cages, enabling longer cage lengths.
  • Horizontal connections: couplers were installed on hook bars and cast in concrete as pending connections for slabs. At a later stage, second-phase rebar could be easily connected to initiate slab การเสริมแรง.

Couplers were also used in underground tunnels and the ventilation building.

For the foundations, Dextra supplied over 100,000 linear meters of โซนิเทค CSL testing tubes, which are easy to install in การเสริมแรง cages and reconnect. These tubes enhance productivity by eliminating the need for tedious and unreliable welding operations. Once installed, they remain securely in place, ensuring stability during cage lifting and handling.

SOCAR Tower, Azerbaijan

SOCAR Tower, Azerbaijan

โซคาร์ทาวเวอร์ is an office tower located on the way to the city center of Baku, the capital of Azerbaijan. It is the tallest building in Azerbaijan and the entire Caucasus region. The building serves as the headquarters of the State Oil Company of Azerbaijan Republic (SOCAR).

The tower features 42 floors and reaches a height of 202 meters. Completed in 2016, it is now one of the most recognizable landmarks in Baku.

For this project, Dextra was involved in the concrete works between 2011 and 2014, supplying the บาร์เทค rebar coupler solution for all rebar connections. The project was supported by บาร์เทค bar-end preparation equipment sets, installed directly on-site and maintained by Dextra’s European after-sales team.

Dextra rebar couplers were supplied to contractor Tekfen for:

  • Vertical bar-to-bar connections in columns.
  • Horizontal rebar connections in slabs.
  • Wall-to-beam connections, where the coupler was cast flush with the formwork in the first phase of concreting. After formwork removal, the connecting rebar was simply screwed into the Bartec coupler.

To enable splicing at locations where rebar had not been prepared with a thread, ซ่อมGrip sleeves and hydraulic equipment were also supplied for precise applications. ซ่อมGrip allows for the convenient splicing of rebar where the protruding length is insufficient for a safe overlap.

Sobha Dream Acres, India

Sobha Dream Acres, India

Sobha Dream Acres is a large residential complex spanning 81 acres, located east of Bangalore, India. This ambitious real estate project features 13 towers of 14 floors, built in record time thanks to the use of precast construction methods, supported by a purpose-built factory equipped with Vollert machinery.

For this project, Dextra provided the owner and contractor, Sobha, with two distinct coupler solutions, supported by threading services.

At Sobha Dream Acres, the กรูเทค precast solution was used for the swift connection of precast elements, either to a footing or directly to another precast element. This ensured a high-performance connection and significantly sped up installation compared to traditional wet in-situ joint methods.

After casting on the production line, the panel was transported to its final location for straightening and bracing installation. Locally sourced non-shrink grout was then injected into the cavity. After injection, the bracing around the precast panel could be removed after just three days.

Dextra does not supply the grout, as กรูเทค is designed to be compatible with multiple non-shrink grout brands that can be sourced locally, reducing costs and simplifying logistics.

To complement the precast solution, Dextra also supplied its บาร์เทค สารละลาย. บาร์เทค was used throughout Dream Acres to splice reinforcement for both cast-in-place and precast applications, allowing for extended precast element lengths.

To support both solutions, Dextra India managed the rebar preparation operations. Rebars with บาร์เทค-threaded ends were delivered directly to Sobha according to their production schedule. The same threaded bars could be used interchangeably with both บาร์เทค และ กรูเทค couplers, as both solutions utilize the same threading system.
