"To enable the limit states to be checked, the design values of the geotechnical parameters, the ground resistance and the actions (e.g. forces or loads), must be determined. The design values of actions (Fd) are derived by multiplying the representative values (Frep) by the appropriate partial factor of safety...." (Section 7.4.2)
