Geotechnical investigations

Geotechnical investigations have acquired substantial importance in preventing human and material damage due to the earthquakes, foundation cracks, and other catastrophes. Geotechnical investigations can be as simple as conducting only a visual assessment of the site or as detailed as a computer-aided study of the soil using laboratory tests. 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 criterion 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 technically suitable construction. Geotechnical investigations have become an essential component of every construction to ensure safety of human beings and materials. It includes a detailed investigation of the soil to determine the soil strength, composition, water content, and other important soil characteristics.

Geotechnical investigations are executed by highly experienced geotechnical engineers and geologists to acquire information regarding the physical characteristics of soil and rocks. The purpose of geotechnical investigations is to design earthworks, pilings and foundations for structures, and to execute earthwork repairs necessitated due to changes in the subsurface environment.

A geotechnical examination includes surface and subsurface exploration, soil sampling, and laboratory analysis. Geotechnical investigations are also known as foundation analysis, soil analysis, soil testing, soil mechanics, and subsurface investigation. The samples are examined prior to the development of the location.

Based on the soil condition, it is very important to carry out a geotechnical investigation in Alberta, BC and SK.
