Balfour Beatty’s 50:50 joint venture, Gammon, has secured a £300m contract to construct a new office building in Causeway Bay, Hong Kong. 

The HK$2.6bn project is on behalf of Mandarin Oriental Hotel Group. 

As part of the contract, Gammon will be responsible for the construction of a new 25-storey office building with associated retail facilities. 

Footbridges will also be built to connect the office block with the World Trade Centre Hong Kong as well as a shopping centre.

This latest contract award follows Gammon’s appointment to demolish the Excelsior Hotel which previously occupied the site of the new office building.

Throughout the project, Gammon will adopt smart construction processes including the creation of a common data environment among contractors, consultants, supply chain partners and the client to enhance collaboration and drive efficiencies.

To reduce the project’s carbon emissions and achieve BEAM Plus New Buildings Version 2.0 as well as LEED platinum certifications, Gammon will deploy the Enertainer – an electric-powered battery storage system developed in partnership with AMPD Energy. 

The Enertainer will be used as the primary power source for construction machinery on site, reducing the need for diesel generators. 

Gammon, headquartered in Hong Kong, is a 50:50 joint venture between Balfour Beatty and Jardine Matheson, the Asian-based conglomerate. The two companies have worked in partnership since 2004.

Kevin O’Brien, chief executive of Gammon, said: “We look forward to working with Mandarin Oriental Hotel Group to bring back another exemplary building to the shoreline of Hong Kong Island, while showcasing our collaborative and digital approaches to modern construction that continues to evolve.

“The sustainable consideration and features of the design will enable the project to achieve the high level of green accreditation that this ambitious project is targeting.”

Works will commence in late 2022 with completion expected in 2025. At construction peak, the project will employ a workforce of approximately 900 people.
