Småhustillverkarens projektering med BIM i jämförelse med 2D-teknik

Sammanfattning: Purpose: A fear of change has been in the Swedish construction industry. Errors and delays are seen as obstacles to development in the construction industry. Industrial construction means more automated manufacturing, which places higher demands on the design. The design stage is the bottleneck for industrial construction with 2D technology. BIM with its information management provides increased coordination, resulting in a number of improvements. The purpose of this thesis is to analyze how the design of small house manufacturers is transformed by a transition to BIM from 2D technology. Method: In order to respond to the goal, the thesis has been based on a case study with the data collection methods observation, experiment and focus group. With observations, students have studied how design with 2D technology looks today for small house manufacturers. The experiment provided an in-depth analysis of how design with BIM can be used. In order to analyze how BIM changes the design, focus group from the company has been used. Findings: The thesis shows that design with 2D technology for small house manufacturers works but that a number of improvements can be made. With BIM, small house manufacturers can streamline their design in time and dependency. BIM improves total design time, but also for each task. BIM helps the information to be handled and used more easily, and that information loss is reduced. Implications: Results show that BIM can streamline the entire design process and is applicable to the small house industry. The workload and time are positively affected by the use of BIM. Each individual planner benefits from BIM in terms of time and addiction. As the design process is not changed but only streamlined, a possible transition becomes easier. Limitations: This thesis is limited to design for small house manufacturers who use prefabrication.
