Double wins at the Hong Kong Awards for Environmental Excellence




At the ITT project, the team has designed Hong Kong’s first marine-friendly hanging cofferdam for pile cap construction to avoid disturbance to the seabed. Alternative designs and methods for bridge deck construction have also contributed to a significant carbon reduction, while total reuse of sediment avoided marine dumping and direct contamination to the marine environment.
While the team at KTW believes that every small steps could contribute to sustainable development. The team has adopted environmental innovative designs during project planning, such as revising the reclamation method for the cofferdam area by using clutched pipe pile wall instead of diaphragm wall to avoid 18,300 m3 marine deposit. They have also proactively implemented waste reduction measures and green procurement during construction, including the adoption of reusable modular strutting for ELS, as well as metal scaffold and steel system formwork.
