This European Prestandard gives common requirements for execution of concrete structures. In particular, this part gives requirements for structures designed according to ENV 1992-1 and for the concrete part of composite structures designed according to ENV 1994-1. In the case of civil engineering works, different oradditional requirements need to be considered and, if required, given in the project specification. This prestandard permits the project specification to state specific requirements relevant the particular structure. This prestandard is applicable to temporary as well as permanent concrete structures.
