UTREDNING AV ARBETSMETOD FÖR KONSTRUKTÖRER VID BERÄKNING AV MODELL

Sammanfattning: Although BIM today is a well-known practice, there are shortcomings, mainly within interoperability and communication. It is relevant to seek solutions through new work methods and not just through new technical solutions. There are difficulties in implementing new work methods, as the industry is known to be routine based.  The aim of the study is to clarify the need for increased efficiency in the design process in terms of model calculations, to investigate the possibilities for an improved work method for construction engineers.  To reach the goal, the data collection methods interview and literature study have been chosen. This have been chosen, in order to portray the reality of the business community as well as current research within the chosen problem area.  The study has generated factors, such as: a more frequent information exchange reduces the risk of information loss. Using standardised details as support for reporting provides the ability to mediate preservation of collective experience.  Interoperability can reduce double modelling (which today is a time-consuming part of the workflow). Using the model in more parts of the process as the model has great potential for this since it contains a lot of information. These factors can contribute to increased efficiency of the construction process in terms of model calculations.  The size of the company is not the only thing that factors in when dividing work load. Clear dialogue between disciplines can create better conditions at the start of projects. By connecting more of the design details to the model it can be used in several stages, such as in the inspection phase. For the development of the preservation of experience, a library of construction details for support in design is recommended. Another recommendation is to start the collaboration between the construction engineer and the architect at an earlier stage, to facilitate their work processes.  The results of the study are nationally applicable. The factors relating to efficiency in cost, time and quality have only been studied briefly. The interview methodology applied to the study limits the generalizability when interpretation of opinions is carried out.
