上海金茂大厦采用钢筋混凝土核心筒与钢结构外框架相结合的混合体系，是当今世界上排名第三高度的大楼。由于上海地区属软土地基，因此金茂大厦的建造有着相当高的难度，尤其是基础与上部结构的施工，上海建工（集团）总公司从实际出发，大力开展科研攻关，在广泛汲取国内外成功经验的基础上，因时、因地制宜，形成了自己独创的施工工艺和严谨的科学管理体系，解决了深基、巨柱和超髙空浇筑与安装等一系列施工难题，仅用4年时间就实现了大厦基本建成的预期目标，创造了世界建筑史上又一新的高速度。

Shanghai Jinmao building is the 3rd highest building in the world at present. The main building consists of reinforced concrete core wall and exterior structure steel frame. It is rather difficult to construct this edifice in such a poor soil condition in Shanghai. Proceeding from actual facts, Shanghai Construction Groups (SCG) makes efforts to conduct technology innovation, and absorbs advanced experiences domestic and abroad wildly. A unit of unique construction technique and a suitable managing system were developed with the growth of this building. SCG successfully solved a series of construction difficulties including deep-foundation work, mega-columns construction, high - altitude construction and erection, and so on. It only spent 4 years on this building, which set a high-speed record in construction history.
