On August 18, China Zun, the tallest building in Beijing built by China State Construction Co., Ltd. - China State Construction No.3 Engineering Co., Ltd. ( consortium ), reached the 70th floor with a structural height of 333 meters, exceeding Beijing International Trade Phase III and reaching the first level in Beijing.

 China Zun is located in the CBD core area of Chaoyang District, Beijing, with a total building height of 528 meters, 8 floors underground and 108 floors above the ground. It integrates Grade A office building, conference, business, sightseeing and various supporting services, and will become the tallest building in Beijing and a new landmark of the capital after its completion.  The project will be capped in July 2017 and fully completed and put into use in October 2018.

 Since the start of the project on July 29, 2013, the project has set a domestic record of 8 of the world's largest and 15 projects.  The project uses the three-dimensional space enclosed by the intelligent jacking steel platform to form running water in different operation layers, and simultaneously carries out steel structure hoisting, welding, steel bar binding, formwork support, concrete pouring, mechanical and electrical pre - embedding, etc. to solidify the insertion and completion time of each process, so that the operation of each process is standardized and simple, the working face is handed over to be controlled, the factory level of the core barrel construction site is improved, and the construction speed of the core barrel is stabilized at 3 - 4 days.
