What is the purpose of conducting a geotechnical investigation?

1. To analyze the economic feasibility of a project

2. To determine soil stability and bearing capacity

3. To assess environmental impact

4. To design building aesthetics

The correct answer is: To determine soil stability and bearing capacity

Conducting a geotechnical investigation is primarily aimed at determining soil stability and bearing capacity. This process is crucial for understanding the soil's physical and mechanical properties, which directly influences the foundation design of any construction project. By evaluating factors such as soil type, moisture content, compaction, and strength, engineers can ensure that the structure will be safely supported by the ground beneath it. Understanding soil stability is vital for predicting how the soil will behave under various conditions, such as changes in load, moisture, and environmental factors. The bearing capacity indicates the maximum load the soil can support without risk of failure, which is essential for preventing structural problems in the future. Hence, this investigation helps in making informed decisions about foundation design, construction methods, and overall project feasibility regarding the site's specific conditions. While evaluating economic feasibility, assessing environmental impact, and designing building aesthetics are important aspects of a project's overall planning, they do not specifically relate to the essential function of a geotechnical investigation, which focuses on the physical properties of soil and its suitability for construction.
