Geotechnical Engineering Basics for Construction
in Construction Technology and InnovationAbout this course
The "Geotechnical Engineering Basics for Construction" course is designed to provide an in-depth understanding of the fundamental concepts of Geotechnical Engineering while adhering to the standards set by the Occupational Safety and Health Administration (OSHA). The course focuses on the application of principles of geology and soil mechanics in solving various engineering problems related to construction.
This course comprises a comprehensive study of ground behaviour and its functionality as an engineering material. Students will explore the science behind soil properties, classification, permeability, compaction, seepage, consolidation, shear strength, slope stability, and how these factors impact the design and construction process. The course also emphasizes understanding the interaction between civil engineering structures and the ground, including superstructures like bridges and buildings and substructures such as foundations, embankments, excavations, tunnels, and more.
The curriculum pays close attention to various testing methods used in geotechnical engineering to determine soil behavior under different types of load. You will learn about recognized lab techniques for determining various fundamental soil properties necessary for design. You'll also learn practical techniques for assessing ground conditions at construction sites and how to interpret the geotechnical data gathered.
Staying true to the OSHA standards, the course also provides practical insights into construction safety practices. We will cover the essential OSHA safety standards and regulations related to construction, particularly those associated with geotechnical engineering, such as excavation safety, slope stability, trenching, and shoring. Students will be trained on how to identify potential site hazards and prevent work-related injuries or accidents.
Additionally, the course will educate students about the role of geotechnical engineers in mitigating the environmental impacts of construction projects. It covers topics such as erosion control, soil remediation, and waste containment that are essential for sustainable construction practices.
Through this course, students gain a well-rounded understanding of the significant role that geotechnical engineering plays in constructing successful and safe infrastructure projects. This course is suitable for practicing engineers looking to deepen their understanding, new engineering graduates, students studying civil engineering, and any individuals involved in construction projects and consultancies who are keen to understand the vital aspects of geotechnical engineering in construction.
"Geotechnical Engineering Basics for Construction" promises a comprehensive understanding of the subject, thereby encouraging and empowering students to make insightful, responsible, and safe decisions in their professional environments.

Soil mechanics and geotechnical engineering are essential branches of civil engineering, focusing on the behavior of soil under various conditions. These fields are critical for the design and construction of foundations, retaining structures, embankments, and other infrastructure projects. A solid understanding of soil mechanics enables engineers to predict how soils will behave under different loads and environmental conditions, ensuring the stability and safety of structures.
Geotechnical engineering plays a vital role in the planning, design, and execution of construction projects. It is a specialized branch of civil engineering that focuses on the behavior of earth materials (such as soil and rock) and their interaction with structures built on or within them. The importance of geotechnical engineering in construction cannot be overstated, as it directly impacts the safety, stability, and longevity of infrastructure.
Understanding soil types and classification systems is essential in geotechnical engineering, construction, and civil projects, as the properties of soil can greatly impact the stability and design of structures. The soil classification process involves grouping soils based on their physical properties, which helps engineers select appropriate construction methods, foundation designs, and materials. One of the most widely used soil classification systems is the Unified Soil Classification System (USCS), but other systems such as the AASHTO (American Association of State Highway and Transportation Officials) system are also commonly applied.
Understanding soil properties is crucial in construction, geotechnical engineering, and civil projects, as these properties significantly impact the behavior of soil under various loads and environmental conditions. The key soil properties that engineers focus on include strength, compressibility, and permeability. Each of these properties affects the stability, design, and safety of construction projects. Proper evaluation and testing of these properties allow engineers to design structures that can withstand the stresses imposed by the soil and external loads.
Site investigation is an essential step in the construction and geotechnical engineering process, providing critical information about the subsurface conditions. The data collected during site investigations helps engineers design safe and stable foundations, roads, and other infrastructure projects. The primary techniques for site investigation include drilling, sampling, and in-situ testing. Each method has its specific purpose and application in determining the physical and mechanical properties of soil and rock at a construction site.
Laboratory soil testing is a crucial component of geotechnical engineering, providing data that informs the design and construction of foundations, retaining walls, embankments, and other structures. After samples are collected during site investigations, laboratory tests are performed to determine various soil properties, such as strength, permeability, and compressibility. These tests help engineers predict how the soil will behave under different loads and environmental conditions.
The foundation is one of the most critical elements in construction, as it transfers the load of a structure to the underlying soil or rock, ensuring stability and safety. The type of foundation used depends on various factors, such as the type of soil, the load-bearing capacity of the ground, and the size and type of the structure. Foundations are generally categorized into two main types: shallow foundations and deep foundations.
In construction, ensuring the stability and strength of the ground that supports a structure is crucial for its longevity and safety. Ground improvement techniques are essential when the natural soil conditions are inadequate to support the intended structure. These techniques are used to enhance the engineering properties of soil, such as its load-bearing capacity, strength, and permeability. In this lesson, we will explore three key ground improvement methods: compaction, grouting, and soil stabilization.
