Abstract—Growing need for construction of infrastructures and buildings in fast urbanization process creates challenges of interaction between buildings under construction and adjacent existing buildings. This paper presents the mitigation of contradiction between two parties, who are involved the interaction, using civil engineering techniques. Through the in-depth analysis of the results of monitoring surveys and enhanced accuracy and reliability of surveys, a better understanding of the behavior of deformable buildings will be achieved. Combination with the original construction documents, the two parties agree that both of them are responsible for building damages and a better understanding for the rehabilitation of the existing buildings is focused on. Three case of studies are used to demonstrate and describe the importance of better understanding of the behavior of existing buildings and their rehabilitations. Two cases were analyzed, in specific approach, in Shanghai. And one can compare oneself to a successful case in London. Therefore, the objective of this study is to employ the mechanisms of soil-structure interaction for buildings adjacent to deep excavations. Finally, both parties are able to achieve a common ground, whereby, excavation safety, economic, and enough serviceability of adjacent building in urban area with soft soil conditions.
