1.1 Scope of EN 1997 1 (1) This document provides general rules for the design and verification of geotechnical structures. (2) This document is applicable for the design and verification of geotechnical structures outside the scope of EN 1997 3. NOTE In this case, additional or amended provisions can be necessary. 1.2 Assumptions (1) In addition to the assumptions given in EN 1990, the provisions of EN 1997 (all parts) assume that: — ground investigations are planned by individuals or organisations with knowledge of potential ground and groundwater conditions; — ground investigations are executed by individuals with appropriate skills and experience; — the evaluation of test results and derivation of ground properties from the ground investigation are carried out by individuals with appropriate geotechnical experience and qualifications; — the data required for design are collected, recorded, and interpreted by appropriately qualified and experienced individuals; — geotechnical structures are designed and verified by individuals with appropriate qualifications and experience in geotechnical design; — adequate continuity and communication exist between the individuals involved in data collection, design, verification and execution. (2) This document is intended to be used in conjunction with EN 1990, which establishes principles and requirements for the safety, serviceability, robustness, and durability of structures, including geotechnical structures, and other construction works. NOTE Additional or amended provisions can be necessary for assessment of existing structures, see EN 1990 2. (3) This document is intended to be used in conjunction with EN 1997 2, which gives provisions for determining ground properties from ground investigations. (4) This document is intended to be used in conjunction with EN 1997 3, which gives specific rules for the design and verification of certain types of geotechnical structures. (5) This document is intended to be used in conjunction with other Eurocodes for the design of geotechnical structures, including temporary geotechnical structures.
