Xiqu Centre (Chinese Opera House) of the West Kowloon Cultural District, Hong Kong, has been awarded the HKIA Merit Award of Hong Kong – Community Building 2020, shortlisted under the Construction Innovation Category of the Structural Awards for the Institution of Structural Engineers, UK, 2019. It is named as one of the World’s Greatest Places by Times Magazine in 2019.
Xiqu Centre is a technically challenging and complex project as it is sited within a cramped urban area and sit directly above the MTR West Rail Metro Tunnels and the Southern end of Austin Station. The total weight of the steel component of the structure is 6,700 tonnes. The roof trusses are up to 6.5 m deep, span of the truss is up to 38 m and incorporate the use of high strength steel. The theatre trusses support sthe load of the 1,100 seat theatre, which is hung below from the roof trusses.
The roof trusses of 1,800 tonne and theatre trusses of 800 tonne were assembled at ground level and was lifted to the final position by strand jacking. The above construction methodology had been integrated with the overall design to enable the trusses to be erected quickly and safely at height. This ingenious approach yielded significant programme and cost savings.
With its distinctive draped beaded curtain-like facade (4 sides of total length of 330 m and 52 m high) spilling over from the roof to the ground, the facade is made up of Aluminum fins without any anodising treatment. The fins are allowed to be weathered naturally and are fixed by cast-in embeds inside the parent structure by connecting to the stainless steel bracket mounted on the mullion system.
