4. Implemented projects Figures in the follow report some pictures taken during the construction phases of the interventions previously described. The common feature in the implementation of the exoskeleton-type interventions (building B and building C) was the maintenance of the operating conditions of the activities during the works. Differently, for the endoskeleton-type interventions (building D), the main feature was the maintenance of the original building envelope even during the construction phases using temporary structures. This choice made it possible to reduce the costs associated with any demolition and reconstruction phases. In Fig. 7, the design elevation is shown for building B in which the external bracing is visible, the contrast beam integral with the building and the shear transmission connector are also shown. In Fig. 8, views of the installed bracing system and the connection system consisting of the connecting rod system is shown for building C. In Fig. 9, for building D, a view of the endoskeleton emerging from the envelope and the connection system with the existing structure is shown.
