The AHA geotechnical report is a tool used to communicate the site conditions and design and construction recommendations to the site design, building design, and construction personnel. Site investigations for building design projects have the purpose of providing specific information on subsurface soil, rock, and water conditions. Interpretation of the site investigation information, by a geotechnical engineer, results in design and construction recommendations that should be presented in a AHA project geotechnical report.

The information contained in this report is referred to often during the design period, construction period, and even after completion of the project (resolving claims). Therefore, the report should be as clear, concise, and accurate as possible. Both an adequate site investigation and a comprehensive geotechnical report are necessary to construct a safe, cost-effective project. Furthermore, engineers need these reports to conduct an adequate review of geotechnical related features (i.e. earthwork, retaining walls, foundations, drainage etc.).
