A geotechnical engineer plays a crucial role in construction by assessing soil and rock properties that are vital for foundation design. This includes evaluating the soil's bearing capacity, settlement potential, and any potential risks associated with geological conditions. By understanding the characteristics of the ground where a structure will be built, a geotechnical engineer can recommend appropriate foundation types and depths, ensuring that the structure has a solid and stable base. This assessment is essential to prevent structural failures and ensure the longevity and safety of the building.

In contrast, the design of the building's architecture falls under the purview of an architect, who focuses on the aesthetics and functionality of the structure. Managing construction project timelines is typically the responsibility of a project manager, who coordinates various aspects of the project to ensure timely completion. Calculating material costs is generally handled by cost estimators or quantity surveyors, who analyze project requirements and market prices to provide accurate cost forecasts. Each of these roles is important, but the specialized focus of a geotechnical engineer on soil and rock properties distinguishes their contributions within the construction process.
