●  Contract type: Engineering supervision

●  Project scale: Investment amount of 750 million yuan

●  Construction site: Nanning City, Guangxi

●  Honors: Awarded the  Luban Award for China Construction Projects, "National Science and Technology Demonstration Project", "Guangxi High Quality Project Award", "Guangxi Safe and Civilized Construction Site", "First Batch of Nanning Quality and Safety Standardization Demonstration Site of Construction Project", "Nanning High Quality Structure Award".

●  Project Overview: The project has a floor area of approximately 310000 square meters, a main height of 220.05 meters, 50 floors above ground and 5 floors underground, and a foundation pit depth of 19.58 meters. It is the first project in Guangxi to use underground diaphragm walls combined with reinforced concrete internal support beams for foundation pit support. The removal of internal support beams is also the first and largest project in Guangxi to use micro expansion blasting demolition.  The project applied 8 major and 21 minor new technologies in the construction industry, as well as 40 green construction technologies. The project team also independently developed 9 patents such as bamboo woven board safety maintenance devices for edge maintenance, and 11 construction methods at provincial level such as one-time blasting construction method for deep foundation pit support. Its key technology for underground diaphragm wall construction was the only achievement in the construction industry of Guangxi to win the Guangxi Science and Technology Progress Award in 2015.
