What is the purpose of a geotechnical report in building design?

The purpose of a geotechnical report in building design is primarily to assess soil conditions for foundation design. This type of report provides essential information regarding the physical and engineering properties of the soil and rock beneath a proposed construction site. The data gathered includes soil bearing capacity, moisture content, and the presence of any potential hazards, such as sinkholes or unstable soil layers. This information is crucial for engineers and architects as it directly influences the design and structural integrity of the foundation, ensuring that buildings are safe, stable, and appropriately suited for the site conditions. Assessing soil conditions enables the design team to make informed decisions about the type of foundation required, thus reducing risks during construction and long-term structural failures.
