Sustainable Infrastructure Systems is a core module designed for Research Engineering students registered on the EPSRC fundedC entre for Doctoral Trainingi n Sustainable Infrastructure Systems (CDT-SIS) at the Faculty of Engineering and the Environment, University of Southampton, as part of the first year taught programme. This module provides formal training in interdisciplinary areas of Engineering and Science within a common framework that addresses infrastructure interdependencies, sustainability and society. The approach adopted is to expose students to a range of real world challenges faced by society in the pursuit of delivering infrastructure essential to the Water, Energy and Transport sectors. The module is timetabled over a week-long block during semester 2 during which students attend lectures and seminars in which experts from both academia and industry present case studies of current problems in which they are involved, illustrating the range of techniques employed to find solutions. The module involves at least two site visits of relevance (e.g. to transport infrastructure construction sites, power stations) during which industry partners discuss socio-economic, political, operational, and strategic challenges faced by the sector they represent. The key theme that runs throughout this module is the identification of common challenges faced by the different industrial sectors in delivering and maintaining often contentious infrastructure projects, and difference or similarities in approaches adopted to find solutions. The module will provide a good background for the Group Design Project and Individual Projects that take place during Semester 2 and the summer, respectively.
