Tianjin Olympic Center Stadium Project in the external shape of a "Water Drop” has a construction area of 158,000m2 and is internally set up with 60,000 audience seats to accommodate up to 80,000 people. Tai'an Road No. 5 Building Project has a construction area of 181,000m2, involving 3 underground floors and 54 floors above ground. The building height is 263m and excavation depth of its foundation pit is 18.2m. Yihang Mansion Project has a total construction area of 57,385m2. Its main building has the building height of 99.95m and the podium building has the height of 21.05m. Transportation Hub Project of Tianjin Railway Station covering an area of 140,000m2 is applied with the construction technique of covered excavation reverse construction method. With the deepest excavation depth of 32.5m, it is the deepest foundation pit in Tianjin up to now. Tai’an Road No. 4 Building (The Ritz-Carlton Hotel Tianjin) applies the exterior finish of European-style shale unplastered compound walls that are complex in structure. All external walls are constructed with traditional masonry techniques. The involvement of more than ten forms such as flat arches, circular arches, fancy walls, marble pillars, splayed windowsills, and back-shaped walls has high standards for building methods and quality. The construction form organically combining concrete frame structure and brick-concrete structure is the first case in Tianjin. The flat arches that are constructed by shale unplastered bricks have the maximum span of 2.8m. The multiple circular arches are built with staggering bricks. 13 kinds of irregular bricks are specially made and carefully constructed to present a beautiful and elegant effect. This technology obtains 3 national invention patents and 3 municipal construction methods. A number of projects have won Luban Awards and National Quality Project Awards, for instance 9# assembly plant for Airbus A320 aircraft assembly line, Tianjin Digital Television Building, Neurology Center of General Hospital of Tianjin Medical University, Jinwan Plaza, Tianjin Cultural Center Grand Theatre, Tianjin Cultural Center Library, Renaissance Conference Hotel, etc. Contracted residential community projects include social security housing community in Ruijing residential district, Chadian Xinyuan Community in Tianjin Binhai New District, Tianfang Meiyu Group Community, Wuyi Sunshine Wuqing Project Phase I (Jinyuan), Tianjin Junliangcheng Demonstration Town and other projects are awarded "China Civil Engineering Zhan Tianyou Awards".
