In the Eurocode series of European standards (EN) related to construction, Eurocode 7: Geotechnical design (abbreviated EN 1997 or, informally, EC 7) describes how to design geotechnical structures, using the limit state design philosophy. It is published in two parts; "General rules" and "Ground investigation and testing". It was approved by the European Committee for Standardization (CEN) on 12 June 2006. Like other Eurocodes, it became mandatory in member states in March 2010. Eurocode 7 is intended to: Eurocode 7 is composed of the following parts

Part 1: General rules

EN 1997-1 is intended to be used as a general basis for the geotechnical aspects of the design of buildings and civil engineering works.

Contents

EN 1997-1 is accompanied by Annexes A to J, which provide:

Part 2: Ground investigation and testing

EN 1997-2 is intended to be used in conjunction with EN 1997-1 and provides rules supplementary to EN 1997-1 related to planning and reporting of ground investigations, general requirements for a range of commonly used laboratory and field tests, interpretation and evaluation of test results and derivation of values of geotechnical parameters and coefficients.

Part 3: Design assisted by field testing

There is no longer a Part 3. It was amalgamated into EN 1997-2
