This diploma work was conducted in collaboration with the Swedish civil engineering construction company Skanska Construction in Stockholm. Their interest is to develop a number of type approved form constructions which can be used during the construction of concrete walls. Skanska focuses on improving safety on their projects and both supervisors and workers have a need for approved form constructions in the current situation. The study is focused on safety and the purpose is to facilitate the preparation before the form work can begin. By studying the literature of the subject and conduct interviews with employees at Skanska Construction, the understanding of the issue and knowledge will be increased. Literature studies, interviews together with production and design have been the basis for a successful study. The work has resulted in three types of approved form constructions to Skanska Construction and the drawings can be used of employees at the company. The form constructions are, by using a CAD-program, presented on drawings in a clear and convenient way.
