Kvalitetssäkring av modellfiler

Sammanfattning: Creating 3D-models is a common feature for the constructor in the planning phase. However, this has proved to be problematic as the models do not meet the right quality. Lacking quality in 3D-models can lead to bad consequences and it is therefore important to perform a quality control on the model. Tyréns in Umeå has seen a need to have a process of controlling 3D-models to ensure that they have the right quality. The purpose of this study has been to analyze whether there are any methods for quality control of 3D-models that Tyréns can make use of today. The goal of the work has been to present a working method that Tyréns can use in the future to quality assure 3D-models. The work has been completed by studying literature from the university library and city library in Umeå. The law about construction and Boverket website have also helped to carry out the work of the report. To get a picture of how problems can look like in a 3D-model, a couple of reference objects have been used. The information about the reference objects are collected from interviews, investigations and magazines. The result of this study shows that there are no general working methods for analyzing 3D-models. On the other hand, there are quality assurance methods in the manufacturing industry that could be used to control the models as well. The problem with these methods is that they are adapted to an industrial environment. This means that they are not developed to detect errors that may occur during the planning phase. Therefore, the quality control methods used in the manufacturing industry are required to be corrected and adjusted so that they can be used to control 3D-models. However, what can be used from industry methods is that the quality control should be planned at an early stage and then carry out the controls. The method developed in this report is a work method that includes planning, control and follow-up, which makes the workflow time consuming. However, the conclusion of the work is that the most important thing about quality control of 3D-models is that it is planned and then performed.
