The ceiling maintenance project for Hong Kong Coliseum
The ceiling scaffold in the Hong Kong Coliseum was built by extending from the metallic pipelines under the ceiling. The scaffold was hanged in the air by wire connecting to the metallic pipelines. The first bamboo was started from the highest point of the auditorium which was also the nearest to the ceiling. This scaffold was double-layered, with thicker bamboos used for the lower layer and thinner bamboos for the upper layer. The lower layer was for maintaining illumination and acoustic facilities and the upper layer was for maintaining air-conditioning facilities. The whole scaffold was composed of 4 sections, with each being built from 4 different corners toward the middle.
