<p>The EN Eurocodes are a new series of standards for construction design in Europe. The development of these codes started originally in 1975 and in present time the progressing work is at the national calibration stage. The goal is to create a common standard for the design of buildings and other civil engineering works throughout Europe and beyond. The purpose is to increase the free circulation of construction products and engineering services. Since the transition to the new standards is getting closer, the constructing engineers and companies will soon stand before great changes. This is why Kadesjös Ingenjörsbyrå AB asked me to do an analysis of the first part of the new standard, i.e. Eurocode 1990, and look at the differences among the existing standards in Sweden and the Eurocodes. The result of this is summarized not only in the report but also in a “User’s manual” which is presented in appendix 1 attached to the report. A limited study of the environmental effects of the transition to Eurocode EN 1990 has also been done. By comparing design calculations of a normal beam in three different materials, steel, concrete and glued laminated timber, one can, for instance, get a general view of how the differences of the two standards affect the required quantity of material. To get an insight of the different opinions that might exist concerning the new standard, a survey based on interviews of a few constructional engineers has been done. There was also discussed if any, and in that case what kind of preparations constructors and design companies are performing to be well prepared when the transition comes.</p>
