Purpose and Background

Designers often think of design and installation of buried pipe as two separate processes. In fact, since performance of buried pipe depends to a large degree upon good soil support, the two processes cannot be separated. Proper design procedures require the coordinated design of pipe and installation and subsequent construction procedures must fulfill design assumptions. This seminar demonstrates the fundamentals of pipe-soil interaction behavior, how soil and pipe behavior can be jointly considered in design and how proper construction methods can achieve design assumptions in the field. The principals of soil-structure interaction covered in this seminar apply to all types of pipe. The primary objective of this seminar is to show how simultaneous consideration of pipe and soil, as two interrelated parts of one pipe-soil system, can optimize pipe performance and longevity, prevent failures, and minimize the high cost of downtime and repairs.

Benefits and Learning Outcomes

Upon completion of this course, you will be able to:

• Explain the latest changes in pipe specifications and why they are being made
• Recognize, from case histories, what can go wrong in pipeline construction and the consequences of not following good practice
• Design installations that minimize risk
• Explain how uncompacted bedding can help pipe performance
• Explain the correlation between soil density, which is measured in the field, and soil stiffness, the soil property that affects pipe performance
• Identify the best in-place density tests for different soil conditions
• Use flowable fill (controlled density fill) for pipe embedment and backfill
• Apply approximate and sophisticated methods for predicting deflection of flexible pipe
• Utilize the ASCE Standard 15-93 for design and manufacture of reinforced concrete pipe and other ASCE standards for reinforced concrete pipe and box sections
• Explain the relationship between pipe and soil and know how to apply this information in your own work to build durable, efficient pipelines which yield substantial short and long term savings for you, your organization, and your clients

Assessment of Learning Outcomes

Students' achievement of the learning outcomes will be assessed via a short post-assessment (true-false, multiple choice and fill in the blank questions).

How to Earn your CEUs/PDHs

This course is worth 1.4 CEUs / 14 PDHs. To receive your certificate of completion, you will need to complete a short post-test and receive a passing score of 70% or higher within 30 days of the course.

How do I convert CEUs to PDHs?

1.0 CEU = 10 PDHs [Example: 0.1 CEU = 1 PDH]
