Schiavone’s has been involved in some of the most complex underground, shaft and tunneling projects ever undertaken, including various contracts. Our expertise in all methods of tunneling, including soft ground, hard rock, TBM, NATM, and drill and blast and excavation, particularly in the congested New York metropolitan area, means that we are ideally suited for this type of work. Our extensive experience dating back to the mid 1970’s has made us a favorite among the owners of these types of projects.
