Summary: 1.1 Scope of FprEN 1997-2 (1) This document provides rules for determining ground properties for the design and verification of geotechnical structures. (2) This document covers requirements and guidance for planning ground investigations, collecting information about ground properties and groundwater conditions, and preparation of the Ground Model. (3) This document covers requirements and guidance for the selection of field investigation and laboratory test methods to obtain derived values of ground properties. (4) This document covers requirements and guidance on the presentation of the results of ground investigation, including derived values of ground properties, in the Ground Investigation Report. 1.2 Assumptions (5) The provisions in FprEN 1997-2 are based on the assumptions given in EN 1990 and FprEN 1997-1. (6) This document is intended to be used in conjunction with FprEN 1997-1, which provides general rules for design and verification of all geotechnical structures. (7) This document is intended to be used in conjunction with prEN 1997-3, which provides specific rules for design and verification of certain types of geotechnical structures. (8) This document is intended to be used in conjunction with FprEN 1998-1-1 which provides the requirements for the ground properties needed to define the seismic action. (9) This document is intended to be used in conjunction with FprEN 1998-5 which provides rules for the design of geotechnical structures in seismic regions.
