Effektivisering av 3d-projektering

Sammanfattning: Purpose: Sweden's construction industry is facing great challenges in form of increased housing with the increasing demands on the environment and economy, this combined with the current low unemployment today and many upcoming retirements. To meet these challenges, it requires development and changes which BIM is considered to handle if it is correct performed. 3d planning is an important part of BIM, where it lays the ground for further step in the building process following two steps, production and management. Method: Selected methods of this thesis is a literature review, semi-structured interviews and document analysis. In the literature review writings about, or related to, 3d planning was studied. The interview method gave more detailed information about the problems that planners experience in reality. The document analysis created a deeper understanding of how 3d design work. Findings: The results show that with simple means it is possible to avoid common problems. Which leads to streamline of 3d design and the entire construction process. This in the form of aspects including economy, the environment and sustainable construction. Implications: Development and improvements in 3d design leads to more effective planning which in contributing to more effective construction. Increase of efficiency can now be justified by the savings in the economy and the environment. But visions of development potential in the further step exists today. One step further, for example, be monitoring the working environment in the planning phase. More education in BIM at all levels of the construction industry should create a better understanding of each other and alleviate the communication gaps that currently prevails. Limitations: This thesis is limited to the design phase of the building process conducted with 3d modeling.
