The paper presents essential principals for the design of geotechnical construction in range accordance PN-EN 1997:2008 Eurocode 7-1. The design aspects of serviceability limit state in comparison with polish geotechnical standards were presented. The design aspects of spread foundations, pile foundations, retaining structures, embankment and slopes and influence of filtration phenomena were discussed. Generally principals of design geotechnical construction in Polish Standards was similar to principals EC 7, however proposed in EC 7 new more complicated coefficients of stability and increasing safety of design.
