The Use of the Observational Method in Deep Excavations for the Realization of a Residential Compound in a Complex Hydrogeological Context

Abstract

The urban redevelopment works of the “Railway Station Area ex-Boschi”, was developed on an area of nearly 17.0000 m2, it entailed the execution of deep excavations in a difficult geotechnical and hydrogeological context. In order to overcome these critical issues a design based on an observational approach was developed. This design considered several possible hydrogeological scenarios and staged excavations over small areas.
The Observational Method has been successfully extended from the more traditional case of tunneling works to the less usual case of deep excavations in large construction areas.
