INFRASTRUCTURE SITES AND SYSTEMS
Learning outcomes of the course unit
The course aims to supply the technical-administrative fundamentals for creating public works, the methods for planning and organising building sites, laws and regulations, organisation and management, materials and operating systems. The subjects will be approached with particular attention to the legislative aspects of public contracts (L.109/94), to financial and economic aspects and to the safety regulations in compliance with Italian Legislative Decree 494/96. The course will have an applicative emphasis, supplying the bases for those who intend to prepare also for roles as Director of Works, Site Director and/or Safety Coordinator in the Planning and Works Execution phases. All the units will be supplemented by practical examples and case studies.
