Course Description: This six-hour course examines how soil behavior affects structural performance, common problems with shallow foundations, slabs-on-grade, and retaining walls, investigation methods to diagnosis problems and causes, the impact of nearby construction on existing foundations, and repair techniques for the type and cause of damage to various types of foundations and retaining walls.
Learning Objective 1:
Learners will be able to explain how soil conditions can affect structural performance and how subsurface explorations methods and non-destructive test methods can diagnose the causes of foundation damage.
Learning Objective 2:
Learners will be able to identify common shallow foundation, slabs-on-grade and retaining wall problem causes and design considerations and methods to determine causation.
Learning Objective 3:
Learners will be able to identify and describe foundation and retaining wall repair methods based on the diagnosis of the problem and its causes.
Learning Objective 4:
Learners will be able to explain how foundations can be damaged by construction activities at nearby sites and how the activity and damage can be monitored.
