SITE ORGANIZATION AND SAFETY: The course is intended for training for Works Management, for site management and for the role of Safety Coordinator in the execution phase, with particular regard to the on-site production phase. To this end, the course deals with the following educational themes, developed in a theoretical part and in an application part: the figures and procedures of the building process. An overall representation of the building process is described which describes the various figures present (client, designer, builder, etc.) and their nature, the competences that each of them must possess, the relationships and procedures identified both at regulatory regulatory level and technical that customary. Finally, the various phases that characterize the construction of a public work are presented. Site installation, use of machines and safety devices. With particular reference to the issue of safety in the workplace, the problems connected with the layout and logistics of the construction site, the operation of machinery and production tools, scaffolding and temporary works, the building site systems, hygienic-assistance services, safety signs, personal and collective protection devices. The exercise activities are related in this phase to the design of the site in its evolutionary phases. Analytical techniques for the management of the production process. The typical decision-making situations of building production management are studied, largely making reference to the analytical formalizations of Operations Research and ISO 9000 standards; in particular, topics such as the Pert techniques for job scheduling and the techniques for optimizing the use of resources are discussed. MANAGEMENT OF SAFETY IN THE PROJECT AND CONSTRUCTION SITE: The teaching is integrated with that relating to "Planning and organization of the construction site" and aims to provide the knowledge and techniques to design and manage safety on construction sites. The materials treated and the strong applicative connotation that characterize it make it functional to allow students to achieve one of the requisites necessary to be able to play the role of safety coordinator, both in the design phase and in the execution of the works.
