Gammon Construction is pleased to announce the topping out of the One Causeway Bay Project, developed by Mandarin Oriental Hotel Group and managed by Hongkong Land. This milestone marks the structural completion of Hong Kong’s newest premium waterfront commercial development.

The building has achieved provisional Platinum ratings from BEAM Plus and LEED (Leadership in Energy and Environmental Design), pre-certification from WELL, and a Platinum rating from WiredScore certification. It is also targeting a Platinum rating from SmartScore certification. The project employs sustainable materials, including green concrete, green rebar, FSC-certified timber, and recycled materials.

Kevin O’Brien, Chief Executive of Gammon said, “At Gammon, we are dedicated to pioneering sustainable construction practices that contribute to a greener and healthier future. Our commitment to environmental stewardship drives us to innovate and set new standards in the industry. This project is a testament to our vision for a sustainable Hong Kong.”

Safety is paramount in every Gammon project. To enhance work safety and efficiency, particularly in the project's central location in Causeway Bay, we have implemented several innovative solutions. Spin pods were used to stabilize the lifting process, and concrete sensors were employed to monitor and ensure quality control. This project is the first in Hong Kong to receive formal approval from the Buildings Department for using concrete sensors to facilitate early formwork striking, thereby improving productivity.

Upon completion, One Causeway Bay will offer 500,000 sq. ft. of premium Grade A office space across 24 floors, along with 55,000 sq. ft. of retail space over 5 floors, including a rooftop bar and restaurant.

Gammon Construction remains committed to completing this project to the highest standards, ensuring a world-class design and finish. We are dedicated to redefining the cityscape and creating a vibrant space for businesses and the community.
