Wuhan Greenland Center Project is the world's third-tallest building with 636 meters.The underground structure has been completed and the main building structure is under rapid construction.During the construction, BIM is playing a key role.This paper introduces the method of setting the jacking formwork system based on BIM technology, and solves problems of BIM application to vertical transportation, turnover materials management, pipeline optimization and steel structure erection.BIM technology makes the installation of the tower crane lifting formwork platform go on smoothly and guarrantees the construction progress on the ground core tube structure.

Gui'an bonded area in Guizhou province is the second integrated free trade zone. The planning area is 2.2 km², with an seine area of 2.1 km². This project is a comprehensive service building in the free trade zone. BIM technology was carried out when the project started. This paper mainly introduces the application of BIM technology in the high support of the composite service building to solve the problems encountered in the implementation and demonstration of the original support scheme and to ensure the smooth, safe and punctual completion of the tall formwork for the entire project.

Wuhan Greenland Center is the highest building under construction in China. Its stiff column steel framework and rebar overlaps each other in a very complicated way, the operation space for binding the rebar is small and the construction faces many challenges, and therefore, the two dimensional drawings can hardly show the structures of the rebar and the steel framework. By applying BIM, the project simulates the construction process of distributing and binding the rebar, solve the problems beforehand, and uses the optimized binding plan of BIM.
