Gammon Construction, Balfour Beatty’s Hong Kong joint venture, has been awarded a contract to construct a residential development project at Tseung Kwan O Town Lot No. 93 worth HK$2.6 billion.

Gammon will employ a range of innovative methods including aluminum formwork in place of traditional timber formwork for the tower structure and 3D scanning and Building Information Modelling (BIM) to assist with detecting construction programme clashes.

Thomas Ho, Chief Executive of Gammon said, “Our team is excited to work with Chinachem Group to deliver excellent and meticulous building works that will add to their impressive and diverse range of high-quality properties. We are looking forward to the unveiling of this new phase of development in the Southern part of Tseung Kwan O.”  

The project includes the construction of six 12-18-storey residential towers, and five four-storey houses which together will provide 857 new homes.

The project is due for completion by the end of 2017.

University of Dresden constructs carbon concrete building

The Technical University of Dresden, collaborating with German architecture firm Henn, is constructing the world’s first carbon fibre and concrete building

The Technical University of Dresden, in partnership with German architecture firm Henn, is constructing the first building to be made out of concrete and carbon fibre, rather than traditional steel. 

The combination of materials, known as, “carbon concrete” has the same structural strength as its steel-reinforced alternative but less concrete is used, according to researchers at the university. 

The building, called “The Cube” is currently under construction at the University of Dresden’s campus in Germany, and is believed to be the first carbon concrete building in the world. Strengthening the concrete, the carbon fibre yarns are used to create a mesh into which the concrete is then poured.

Unlike steel, the mesh is rust-proof meaning that the lifespan of carbon concrete is longer than that of the more typical steel-reinforced concrete. This also allows the layers to be much thinner than steel. 

The design and shape of The Cube 

According to the companies, the flexibility of carbon fibre allows the walls to fold up and become a roof. In a statement talking about the building’s design elements, Hen said: “The design of The Cube reinterprets the fluid, textile nature of carbon fibres by seamlessly merging the ceiling and walls in a single form, suggesting a future architecture in which environmentally conscious design is paired with formal freedom and a radical rethinking of essential architectural elements.

"The wall and ceiling are no longer separate components but functionally merge into one another as an organic continuum.” Displayed as a showpiece for TU Dresden’s major project, backed by the German Federal Ministry of Education and Research, The Cube aims to explore the potential uses of carbon concrete in construction. 

"Carbon concrete could contribute to more flexible and resource-saving construction processes, and switching to carbon concrete could reduce the CO2 emissions from construction by up to 50%," Henn said in a statement. 

Bio-based carbon fibre under development to reduce carbon footprint

While carbon fibre may be lighter and stronger than steel, it has a much higher carbon footprint. Describing the material’s impact on the environment, Dr Erik Frank, Senior Carbon Scientist at the German Institute of Textile and Fibre Research Denkendorf (DITF), said it is “usually very bad.” To reduce the carbon footprint, Frank is finding ways to make carbon fibre out of lignin, a common plant-based substance found in the paper manufacturing industry.
