The completion of the project will be a further step towards Hangzhou’s internationalization. Our company won the bid to build a part of the comprehensive building of CNAC, meteorology and communications at Hangzhou Xiaoshan International Airport. This article will focus on the construction of towers and platforms in the flight management building. The tower is the command and management center of the airport and is the landmark of the airport (Figure 1). The tower is composed of two cylinders, inner and outer cylinders. The diameter of the inner cylinder is 3.45m, the wall thickness is 250mm, the diameter of the outer cylinder is 6.6m, and the wall thickness is 400mm. The inner cylinder is an elevator hoistway, and the inner and outer cylinders are spiral stairs. The total height of the structure is 74m. The height of the shear wall of the shaft is from -2.5 to 63.47m. The external wall of the cylinder is fair-faced concrete, which needs to be decorated above the elevation of 48.05m. The internal wall is ordinary concrete.
