20-year-old paper reveals many problems with Sage Tower
At the same time, a 20-year-old master’s thesis from Huazhong University of Science and Technology, “Analysis of Shenzhen Saige Plaza Construction Project”, has been circulating on the Internet. The thesis revealed that there were indeed many construction problems in the construction of the Saige Building.
The thesis pointed out that the construction of the Saige Building took one year to build the foundation, digging holes and other procedures, and many times in the middle of the “technical design adjustments”, and failed to provide a complete construction plan in time.
Among them, the most serious problem of the Sage Building is the roof antenna vibration. On April 8, 1999, after the steel structure was topped out, the construction of the antenna part was not completed until September 30 of the same year. Pedestrians on the ground found the antenna was swaying violently. It was windy and sunny in Shenzhen at that time, and it turned out that the design of the antenna was miscalculated causing resonance.
The paper stated, “Fortunately, it was on a breezy day, if a strong typhoon had hit, the consequences would have been unthinkable.” The paper also mentioned that, in order to solve the problem, the antenna was sawed off and replaced by a cut.
Public information shows that the Sage Building is located in Huaqiang North, Futian District, Shenzhen, invested and built by Shenzhen Sage Group. It is the landmark building of Shenzhen in the cross-century. With a total height of 355.8 meters, 79 floors, 75 floors above ground and 4 floors underground, and a total construction area of 170,000 square meters, it is the landmark building of Huaqiang North pedestrian street and the tallest steel pipe and concrete structure building in the world at present.
Shenzhen Saige Group is a limited liability company funded by four shareholders, including Shenzhen State-owned Assets Supervision and Administration Commission, China Huarong Asset Management Company, China Oriental Asset Management Company and China Great Wall Asset Management Company. The Group has been awarded the title of National Top 100 Electronic Enterprises and Guangdong Top 100 Enterprises for 10 consecutive years.
