King Power Mahanakhon, Thailand

King Power Mahanakhon is a 77-storey skyscraper in Bangkok. Standing at 314 meters, it became Thailand’s tallest building upon its completion in 2016. Mahanakhon is located in Silom, Bangkok’s busiest business district, directly above the Chong Nonsi BTS Skytrain station. The project was developed by PACE and built by Bouygues-Thai.

基础

Building foundations in Bangkok is always a challenge. With the city situated on sandy and humid soils, foundations must be deep, and most projects feature thick 地下连续墙 (D-Walls) to prevent water infiltration.

For the D-Walls of Mahanakhon, Dextra supplied 巴特克 rebar couplers that were mounted on hook bars, installed horizontally, and cast in concrete. This application allows for the reconnection of bars to the D-Wall at a later stage when starting slab 钢筋/增强筋.

Additionally, 有头条 were installed in the thick foundation mat. 有头酒吧 are a superior alternative to 弯钩 in congested areas, offering high-performance anchorage while being easier to install.

上层建筑

The tower is built around a 心墙, constructed using slip-formwork, and is surrounded by 12 mega columns. To connect the columns to the 心墙, Dextra supplied Bouygues-Thai with its renowned 巴特克解决方案。巴特克 couplers, installed flush with the formwork and cast in concrete, allow for second-phase bar reconnection, bridging the columns and 心墙.

In the mega columns, rebar couplers were also used to perform bar-to-bar vertical connections.

空中酒吧

For the rooftop skybar, Dextra supplied Tension Rod Systems. These systems, equipped with fork ends, provide aesthetic and efficient anchorage, making installation simple and effective.

The New Champlain Bridge is a 3 km-long bridge spanning the Saint Lawrence River at the southeastern entrance of Montreal, Quebec, Canada. As one of the busiest bridges in Canada, it plays a crucial economic role for the city, serving as a key route to the United States, located 60 km south.

Replacing the Older Champlain Bridge

The New Champlain Bridge is replacing the existing Champlain Bridge, which was commissioned in June 1962. The older structure began showing signs of corrosion in 1994. After several temporary safety measures were implemented to keep the bridge operational, a replacement project was initiated in 2007. For a time, both bridges will stand side by side until the older structure is fully dismantled, with most of its materials planned for recycling.

A Focus on Corrosion Resistance

The New Champlain Bridge is designed to last at least 125 years and accommodate 50 million vehicle crossings per year. Given the corrosive environment caused by frequent road de-icing, corrosion resistance was a top priority. Duplex stainless steel rebar was installed in critical areas to enhance durability.

For this project, Dextra recommended using Duplex Stainless Steel Rolltec couplers and anchors. This specialized version of our Rolltec® system replaces standard couplers and anchors with an improved duplex steel alternative, offering superior corrosion resistance.

The Rolltec® solution is well-suited to the Canadian market and is approved by the Quebec Ministry of Transport. With a single-operator threading machine and 30-second threading cycles, it provides high productivity, making it ideal for high-labor-cost markets like Canada.

More than 10,000 Stainless Rolltec® couplers were supplied for this project, primarily for bridge spans. These couplers were used to splice large-diameter reinforcement bars, ranging from 35M (#11) to 55M (#18)—the largest size available in our Rolltec® range.

Additionally, about 10,000 Rolltec® stainless steel end anchors were delivered for sizes up to 55M (#18). Rolltec® Headed Bars use the same threading system as the couplers, simplifying production and installation.

Taishan EPRs are two nuclear reactors of the EPR type, each with a capacity of 1,750 MW, built by Areva and located near Taishan in Guangdong province, China.

Dextra was present on-site from the beginning of construction in 2009 until 2016. Reactor operations were planned to start in 2017.

For this challenging project, Dextra supplied its Griptec rebar splicing solution, which was used in the concrete structure of the reactor.

The Bartec rebar coupler solution, as well as Headed Bars, was also used in other buildings of the project.
