Establishes the requirements for the execution of effective geotechnical site investigations and provides a standardized system for the description and classification of soils and rocks, which is largely normative. It addresses spatial and physical characteristics of soil, rock and groundwater, but does not cover the chemical, biological or other environmental aspects of the investigation of contaminated ground.
This Standard specifies requirements for the execution of geotechnical site investigations and provides a standardized system for the identification, description and classification of soils and rocks.

(a) new construction;
(b) maintenance of existing facilities;
(c) the evaluation of post construction performance;
(d) the assessment of failure; and
