Abstract: The deep excavation for the Suning Square is located in the north of Shanghai Bund. The proposed deep excavation has a very restrict environmental requirement and complicated geotechnical conditions due to its close approximate to the adjacent metro tunnel and historical buildings. Base on the specific requirements of the project, the metro tunnel and the historical buildings were closely monitored during the construction and these monitoring data were used to guide the exaction construction. The safety of the deep excavation and the adjacent structures were ensured during the construction  

Key words: Deep Excavation, Complicated Environment, Informational Construction, Excavation Monitoring
