Course description and aims

In this course, basic concepts of infrastructure maintenance are explained, and the knowledge on technologies associated with infrastructure maintenance is also explained such as inspection, performance evaluation, future prediction, repair and reinforcement, link with structures' design, etc. Furthermore, some recent examples of infrastructure maintenance are introduced for the purpose of understanding the practices of maintenance on site.
The maintenance is essential to use infrastructure which was constructed for ensuring our safe and comfortable lives and active economy. This course focuses on concrete structures and steel structures, which are main components of the infrastructure. The basic principles of inspection, performance evaluation, future prediction, and countermeasures are explained, and as many practical applications as possible to actual maintenance works are introduced. Through the latest best examples of infrastructure maintenance such as the applications of integrated technologies and asset management, students are required to find the problems related to infrastructure maintenance, and consider possible solutions by themselves.

Student learning outcomes

By the end of this course, students will be able to:
1) Understand and explain the basic concepts of infrastructure maintenance.
2) Understand the principles of maintenance technologies such as inspection, performance evaluation, future prediction, and countermeasures, and explain their applications to actual practices.
3) Analyze the latest examples of maintenance in details, and apply the obtained knowledge to actual maintenance works.
