EN 1997 Eurocode 7 shall be applied to the geotechnical aspects OF the design of buildings and other civil engineering works and shall be used in conjunction with EN 1990:2002 that establishes the principles and requirements for safety and serviceability, describes the basis of design and verification and gives guidelines for related aspects of structural reliability. Numerical values of actions on buildings and other civil engineering works to be taken into account in design are provided in EN 1991 for the various types of construction, whereas actions imposed by the ground, such as earth pressures and by ground water, shall be calculated according to the rules of EN 1997. Separate European Standards shall be used to treat matters of execution and workmanship. In EN 1997 execution is covered to the extent that is necessary to comply with the assumptions of the design rules. EN 1997 does not cover the special requirements of seismic design. EN 1998 provides additional rules for geotechnical seismic design, which complete or adapt the rules of this Standard.
