Its main tower is constructed with ultra-high multi-limb steel and hybrid combination tower, and the highest main tower reaches 345.6 meters, with high technology requirements and difficult line control.

For the cross beam construction process is complex, the concrete casting is difficult, the safety risk of high-altitude work is high, the large volume of concrete inside and outside the temperature difference is difficult to control and the prestressing tensioning difficulty and many other difficulties, MBEC advance planning program, overcome the recent rare sustained high temperature weather, more than 200 builders fighting high temperature, fighting the heat, reasonable adjustment of labor time, for the successful completion of the beam construction task to provide comprehensive protection.
