The purposes of a Geotechnical Investigation are to investigate the soil and geologic conditions of a property and to provide recommendations and design criteria for construction. The scope of a Geotechnical Investigation includes review of available literature; conducting on-site exploration, mapping/logging and sampling; and laboratory testing of samples obtained in the field. The collected data is analyzed and geotechnical criteria for foundations, retaining walls, site grading and site drainage are developed.
This criteria chiefly consists of the load bearing capacities and anticipated lateral forces from the onsite soil and rock. The culmination of the investigation is a report summarizing the field and lab findings; conclusions regarding the geotechnical impacts of the site; and recommendations for the most geotechnical suitable construction.
