Den juridiska statusen för 3D-modeller som bygghandlingar

Sammanfattning: Introduction – This thesis in Building Engineering at Jönköping University, in collaboration with Tyréns Sweden AB, examines the issues surrounding 3D models as construction documents from a legal perspective and investigates how digitization affects stakeholders in the construction industry. The goal of the study is to explore a relevant and interesting research area in order to contribute to knowledge development and the advancement of new theories or methods in the field. Method – The study will employ qualitative research, including primary data collection through interviews, to address the research questions posed in the report. The authors have chosen this method to achieve a comprehensive understanding of the respondents' perspectives and identify important themes and patterns. The interviews were conducted with participants from various sectors of the construction industry to obtain a broader picture of the subject. Results – The study revealed that there are certain legal barriers to the use of 3D models as drawing documentation. These barriers are related to a lack of knowledge and uncertainty in handling the models. This includes issues of copyright, liability, and evidential value. There is a need to update current regulations to facilitate the management of digital models. Analysis – The analysis of the results clarifies that industry standards and clearer guidelines would prevent uncertainties and address knowledge gaps in the use of BIM and 3D models. An industry standard could have facilitated a smoother transition to a more digitized construction industry. There is also a need for education in the field for professionals and decision-making stakeholders. Discussion – The discussion focuses on possible solutions to the identified problems, such as the development of standards and guidelines, education, and regulatory updates. There is also a need to raise awareness about the legal aspects of using 3D models in the construction industry, as the uncertainty regarding their legal status is high. Legally, it is possible to use 3D models as contractual documents, but the study shows that concerns about the legal aspects are a reason for the weak implementation. Keywords – 3D model, 3D design, BIM, Building Information Modeling, construction documents, contractual law, and copyright.
