IMPLEMENTERING AV BIM VID MATERIALDOKUMENTATION : EN GRANSKNING AV MILJÖCERTIFIERINGS UTVECKLING

Sammanfattning: Purpose: The study relies upon the development of green buildings due to an increased level of acknowledgement of environmental impacts, caused by the building industry. Building materials are one big factor that have a negative impact on the environment. Building Information Modeling (BIM) are constantly being developed in the construction industry because of unlimited technology. The purpose of this study is to see a digitalization of documentation of materials by using BIM, and what consequences this meets regarding coordination. Method: The study used three qualitative methods: literature study, interviews and document analysis. The literature study is based on current research on the subject. An analysis consisting of documents including requirements from three green building certification systems has been done to present how they differentiate. The interviews complete the work with a practical point of view. It presents the work towards green buildings and on what level BIM may be included in the building industry. Respondents are people working with environmental questions, construction management and experts within the field of BIM. Findings: Green building certifications in Sweden are developing to be much more alike, because they are starting to relay on the same kind of requirements. This means there are not many differences when using one or several types of green building certification systems. The combination leads to effects of synergies. The results from Aspö Eko-logi shows that its time consuming and cost inefficient since documentation is required. BIM is established in the construction business, but not with regards to material documentation. Several issues regarding coordination could be solved through BIM. Research on BIM connected with green building certification has been studied on an international level, regarding LEED. This study shows how this could be adapted with Swedish environmental certification systems and also proves that the technology exists. The study presents benefits from using BIM with regards to coordination. Implications: Implications of the study shows that more than one environmental certification system on a project does not have big difference on the documentation of materials. The study creates awareness within the building industry regarding the potential of BIM and its implementation on environmental certification. A BIM-based method could cause benefits such as efficiency, improved coordination, more clarity and digital documentation. Limitations: The study examines a project, which is one of the first in Sweden that uses more than one green building certification system. The report does also only examine LEED, Miljöbyggnad and Svanen. The study has produced a possible BIMbased method regarding material documentation, which partly is based on interviews with persons in the construction process of a project. This will affect all the involved professions throughout the building project, none of which has been interviewed in this study. This makes the result not applicable to other professions. However, they will still be applicable to similar companies and projects within construction manufacturing.
