(1) EN 199116 provides principles and general rules for the determination of actions which should be taken into account during the execution of buildings and civil engineering works. NOTE 1 This part of EN 1991 may be used as guidance for the determination of actions to be taken into account for different types of construction works, including structural alterations such as refurbishment andor partial or full demolition. Further rules and guidance is given in Annexes A1, A2 and B. NOTE 2 Rules concerning the safety of people in and around the construction site are out of the scope of this European standard. Such rules may be defined for the individual project. (2) The following subjects are dealt with in this part of EN 1991. Section 1 : General Section 2 : Classification of actions Section 3: Design situations and limit states Section 4 : Representation of actions Annex A1 : Supplementary rules for buildings (normative) Annex A2 : Supplementary rules for bridges (normative) Annex B : Actions on structures during alteration, reconstruction or demolition (informative) (3) EN 199116 also gives rules for the determination of actions which may be used for the design of auxiliary construction works as defined in 1.5, needed for the execution of buildings and civil engineering works.
