Description
Modern subsurface infrastructure is essential for the functioning of contemporary society, encompassing a wide range of piping systems used in sewers, drainage, subway tunnels, water mains, and utility conduits. Although often overlooked, these buried pipelines are critical to our everyday lives. These systems can deteriorate without proper maintenance and design, leading to service disruptions, costly repairs, and extensive legal disputes. This course comprehensively explores the design and analysis of buried pipes, focusing on understanding the complex dynamics that affect these underground lifelines.

Participants will delve into the latest engineering techniques for calculating external loads on buried pipelines, including the effects of soil subsidence, temperature changes, seismic activity, and other environmental factors. The course also covers designing various types of pipes, such as rigid, ductile, and flexible materials, using AWWA and ASTM guidelines. Through practical examples and case studies, attendees will learn how to apply these principles to real-world situations, ensuring the integrity and longevity of buried pipeline systems.

By the end of this course, attendees will have a thorough understanding of the critical aspects of buried pipeline engineering. They will be equipped with the knowledge to design robust pipeline systems that meet modern standards and address the specific needs of different environments and applications.

Who Should Attend
This course is ideal for professionals involved in planning, designing, constructing, and maintaining buried pipeline systems. Construction managers, utility engineers, geotechnical and civil engineers, city managers, pipeline engineers, and consulting engineers will significantly benefit from the content covered. It is also valuable for contractors, pipeline system fabricators, and manufacturers who seek to enhance their understanding of buried pipeline design and application.

This course may also interest project managers, environmental engineers, urban planners, and infrastructure consultants involved in projects requiring a deep understanding of subsurface piping systems and their design considerations.
