The choice of selecting framework is a central part of any construction project, accounting for about 25 percent of the total construction cost. Today there’s great focus on developing and improving the construction business and the framework selection receives significant attention. Research shows that frames with load-bearing walls are particularly effective in multi-dwelling buildings. The bearing walls are either casted on site or mounted as prefabricated elements. Depending on what’s preferred, the two methods leads to differences in time and costs. Overall the framework choice is difficult and studies suggests that companies make the choice based on old experience, rather than based on substantiated facts.

The authors aim with this report is to examine and calculate the costs for three alternative framework systems for a specific project. The report will treat the economics but also the time aspect. To add further value, the authors will also present pros and cons for each frame. The study is conducted as qualitative and based on existing theories, which are compared with new empiricism. The results show that a frame casted on site provides the greatest economical savings and is therefore seen as the most beneficial choice for the examined project.
