  • Impression of BMU 02 for West Kowloon

West Kowloon Government Offices

Location: West Kowloon, Hong Kong
Year: 2018
Number of units: 2 traversing roof cars + 1 monorail system

West Kowloon is a part of Kowloon, Hong Kong which is situated within the Yau Tsim Mong District. This newly developed area consists out of a stretch of reclaimed land, which was realized in the late 20th century. West Kowloon is a mixed use zone consisting out of large commercial, residential and leisure developments.

In 2018 two brand new government offices arose at Hoi Ting Road in Yau Ma Tei. The area and buildings are constructed by design of renowned architectural firm of Andrew Lee King Fun & Associates Architects. The two glass towers hold over 79 000 m2 (850 345 ft2) of office space for government use, as well as a number of arts and educational venues.

Our installation Partner JEC was selected to provide building maintenance solutions for the two towers (called north and south tower) and XSPlatforms supported in the design.

For cleaning and repair purposes a number of different facade access solutions are installed around the two towers. First off, both towers are equipped with their own traversing and telescopic roof car, with the largest of the two being installed on the south tower. This building maintenance unit has a maximum telescopic outreach of approx. 21,5 meters (70.5 feet). All main functions of both roof cars are identical.

Further we integrated a ceiling-mounted XS110-type monorail systems on the inside of both towers. Maintenance personnel can access these systems by means of the included self-hoisting gondola, which is interchangeable between the two systems.
