Design, construction and monitoring of a building with deep basements in Rome

Excavations for the construction of a tall building with deep basements in a congested area in Rome, close to the Tiber river, are described. The project was technically challenging due to the close proximity of existing buildings, the interaction with the river and the poor geotechnical properties of the alluvial deposits. This well-documented case study addresses the geotechnical and structural issues involved in the development of the design and construction process. Particular attention is focused on the prediction of excavation-induced displacements and on the efficiency of the water wells introduced to increase safety margins against the hydraulic uplift of the excavation bottom.
