Renovation of Qingpu Gymnasium and Training Hall in Shanghai Qingpu, Shanghai architects:Yue Hu, FangQing Tai structures:Hui Li, YanPing Zhang systems:ShaZhou Xue, Wei Shen cost engineer:HuiYing Liu The Qingpu Gymnasium and Training Hall are located in the old urban area -- Qingpu District, Shanghai, and was built and expanded in 1980s. The two buildings had some important factors that lack of modern sense in shape, such as the batter of external walls and semicircular entrance canopy of the Gymnasium and the batter of external walls, cambered glass curtain wall, and exterior stairway of the Training Hall, etc. In addition, the indoor facilities in the two building were out of date. The employer entrusted the Architect to renovate the external decoration of the Gymnasium and Training Hall, to improve the shape and style of the buildings to a new level, and renew the interior facilities and equipment partially in the two buildings to improve functionality. The renovation faced many difficulties, mainly in fund and fundamental data aspects. In view of the limited gross investment, the shape, facades, external environment of the buildings and the indoor facilities in the Gymnasium were mainly renovated and the interior facilities in the Training Hall were improved partially, while minimizing the impact to the existing main structure of the buildings. In the work, the exterior of the buildings was renovated by modifying the shape of batter -- an envelope was added, the logical relationship in geometry in shape was enhanced, and the shape was livened up appropriately. For the interior of the Gymnasium, the functionality for small matches was improved, the spectators' stands was rebuilt, and auxiliary rooms and service facilities for the audiences were added. The new envelope was built with three materials: polycarbonate plates for the top layer, perforated aluminum alloy pates for the bottom layer, and square aluminum alloy tubes at partial locations. Though polycarbonate plates belong to a building material that is not commonly used in buildings, utilizing a single-layer plate design on building facades has unique effects. Polycarbonate plates are light in weight, safe, simple in structure, don’t cause major modifications to the main structure, and are favorable for reducing construction cost; in addition, the transparency feature of polycarbonate plates can meet the requirement for indoor day-lighting. Single-layer polycarbonate plates in thickness not less than 4.5mm, in ivory-white color, with ultraviolet resistance feature on both sides and matte surfaces, were used in the work. The polycarbonate plates were connected closely and firmly in horizontal and vertical directions with a weaving technique, to provide an "open coat" to the building. The moderate texture of the polycarbonate plates had rich modern sense, and was consistent to the urban environment.
