Balfour Beatty's Hong Kong subsidiary has won a £150m contract to build a 70-storey office building in the Chinese city.
Gammon Construction, which is 50% owned by the UK-based contractor, will build the One Island East tower on the eastern shore of Hong Kong.
Developer Swire Properties is behind the project and the surrounding business district. The tower is expected to be complete by March 2008.
Ian Tyler, Balfour Beatty chief executive, said: "We are delighted to have been selected to build this major addition to one of Hong Kong's best planned and established business districts.
"Gammon has a successful and long-standing relationship with the Swire Group and the two companies have jointly developed a number of innovative techniques to accelerate construction and protect the environment before, during and after construction."
