Advancing the Use of Innovative Construction Materials in Hong Kong
By pioneering next generation construction materials, AECOM is helping to reduce embodied carbon, enhance durability, and set new benchmarks for sustainable development. These innovations not only align with Hong Kong’s Climate Action Plan 2050, but also pave the way for greener, more resilient infrastructure for future generations.
Steel Fiber Reinforced Concrete (SFRC)
This innovative material has been successfully applied in metro systems around the world. Known for its enhanced crack resistance and corrosion protection, SFRC contributes to improved tunnel durability and reduces CO2 emissions by more than 28% compared to conventional methods, supporting sustainable infrastructure development.

S690 high strength steel
AECOM introduced this sustainable material in Hong Kong through the construction of two landmark arch bridges in Tseung Kwan O — the Cross Bay Link and the Promenade Southern Bridge — achieving carbon reductions of 22% and 18%, respectively, compared to conventional structural steel.

S960 ultra-high strength steel
S960 ultra-high strength steel has been successfully applied in two footbridges within the Northern Metropolis, showcasing its potential for broader use in future urban infrastructure projects. This material significantly reduces material weight — from an estimated 5,500 tons of concrete to just 600 tons of steel for the quadruple-span circular deck plus four link bridges. This approach has also resulted in 30% cost savings and a 65% reduction in carbon emissions.
