46、5 of the Treaty. The objective of theprogramme was the elimination of technical obstacles to trade and the harmonisation oftechnical specifications.Within this action programme, the Commission took the initiative to establish a set ofharmonised technical rules for the design of construction works wh
47、ich, in a first stage,would serve as an alternative to the national rules in force in the Member States and,ultimately, would replace them.For fifteen years, the Commission, with the help of a Steering Committee withRepresentatives of Member States, conducted the development of the Eurocodesprogramm
48、e, which led to the first generation of European codes in the 1980s.In 1989, the Commission and the Member States of the EU and EFTA decided, on thebasis of an agreement1between the Commission and CEN, to transfer the preparationand the publication of the Eurocodes to CEN through a series of Mandate
49、s, in order toprovide them with a future status of European Standard (EN). This links de facto theEurocodes with the provisions of all the Councils Directives and/or CommissionsDecisions dealing with European standards (e.g. the Council Directive 89/106/EEC onconstruction products - CPD - and Council Directives 93/37/EEC, 92/50/EEC and89/440/EEC on public works and services and equivalent EFTA Directives initiated inpursuit of setting up the internal market).Foreword 1Agreement between the Commission of the European Communities and the European Committee fo
