New underground lines in historic centres: Experiences in Brescia

摘要

The field of engineering the “preservation” of historic or artistic heritage need not be confined only to “structural” interventions. In recent years in Brescia (North Italy), an excavation of several kilometres was completed by TBM in delicate geological and geotechnical conditions, in interaction with a historic centre dense with buildings of considerable importance, in masonry and with superficial foundations. When operating in sensitive areas, a reliable reconstruction of the setting’s history, through the integration of skills with the local administrations, universities and specific experts, is a key basis for studying the appropriate work sequences and identifying the best technologies of operation. In Brescia, Astaldi S.p.A., with its consultants, has played an active part in this process, coordinating and synthesizing the contributions of all the local stakeholders involved; the capacity for collaboration and coordination of a broad spectrum of disciplines and contributions allowed some very complex interactions to be successfully resolved.
