[EN] The Management of the Architect or Building Engineer in Restoration works in defensive buildings such as (towers, walls, castles, etc.) has an exhaustive and specific workforce due to the particularities especially in the environment of the Health and Safety Coordination. This communication will focus on the management of the technician on the Prevention of Occupational Risks in the Restoration, Rehabilitation and Consolidation works on defensive constructions chosen by the author of her International Thesis from the point of view of their integration in all processes: definition and Execution of the activities to be carried out. The destination and final objective is to ensure the physical integrity of the workers who are in contact in the Restoration of Historical Heritage. Research has been carried out in this area both in Andalusia and in the South of France, around the Mediterranean, reflecting the comparison of particularities as an example in 2 defensive interventions: “Restoration in the tower of Castle Molares (Sevilla)” and “Consolidation of Castle Olvera (Cádiz)”. The Technician's work is fundamental for the control of risks in the workplace, especially in the consolidation and restoration of defensive heritage. The actions of the Health and Safety Coordinator in the execution phase in the Restoration or Rehabilitation differ considerably with the works of Nueva Planta, since the stability of the building must be guaranteed in addition to the difficulty involved in the execution procedures and the “surprises” that can be found when acting on the property of this type. Documents are prepared reflecting the modifications in the Restoration Process that will entail new “occupational risks” and the consequent “health and safety measures” that will have to be taken to eliminate or minimize as indicated in Law 31/95 of PRL.
