The document discusses the important role of the geotechnical engineer in designing structures. The geotechnical engineer visits the construction site, understands the layout and location, and collects soil data by excavating pits and conducting bore hole investigations. Samples are sent to accredited laboratories for testing. The geotechnical engineer analyzes the soil data and submits it to the structural engineer. He works with the structural engineer to carry out the foundation design based on the soil conditions.
