Course Highlights

This online engineering PDH course is an introduction to the methods of evaluating the stability of shallow and deep excavations. You will learn about the two basic types of excavations: "open excavations" where stability is achieved by providing stable side slopes, and "braced excavations" where vertical or sloped sides are maintained with protective structural systems that can be restrained laterally by internal or external structural elements.  You will be introduced to the methodology for selecting and designing excavation systems including consideration of soil type and strength parameters, groundwater conditions, slope protection, side and bottom stability, vertical and lateral movements of adjacent areas, and effects on existing structures.


This 2 PDH  online course is intended for civil, structural and geotechnical engineers and other design and construction professionals interested to learn the fundamentals of excavation in soils for stability and safety, as they relate to open cut excavations, trenching, rock excavation, excavation stabilization and safety, embankment cross-section design, and borrow excavation.

Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Learning about sloped and vertical open excavation cuts
  • Learning about the principal factors influencing trench stability
  • Understanding the primary considerations for slope design in different soil types
  • Learning about the two excavation types: "open excavations" and "braced excavations"
  • Learning about trench excavation support systems
