Effektivisering och förbättring av egenkontroller i byggindustrin: Nulägesanalys av hanteringen av egenkontroller ur byggentreprenörens perspektiv

Sammanfattning: Self-inspections are used in almost every industry to continuously ensure that the production meet current requirements for safety, quality, and performance. The construction industry is no exception. Self-inspections also aim to clarify which entrepreneur is responsible for each part of the project in the event of warranty issues and should be seen as an opportunity for the contractor to inspect their work before vacating the project. Currently, there are problems in the handling and execution of self-inspections in the construction industry that directly undermine their purpose. As a result, easily correctable errors are not detected during the production stage but only during the warranty stage, leading to costly and time-consuming interventions in the future. This thesis aims to examine potential resistance and obstacles in the self-inspection process in construction projects from the perspective of the main construction contractor. The thesis will also result in proposals for improvement and streamlining of selfinspection work to minimize the risk of production errors and increase the quality of the work performed. The research is conducted as a combination of a literature and interview study, where previous research on the self-inspection process in the construction industry, along with interviews with main construction contractors, form the basis. The study's findings concluded that resistance in the self-inspection work is primarily linked to a lack of knowledge and education regarding its purpose. A consequence of this is that contractors may conduct self-inspections retroactively, which goes against their intended purpose. According to the interviewees, a common problem was also that the self-inspection process is rarely included in project planning and therefore not followed up on as intended in the project. The results also showed that resistance to change is mainly related to opposition to digitization and difficulties in effectively using digital tools. The self-inspection process can be improved by educating contractors about the purpose of self-inspections and creating an understanding of their use in the construction process. The analysis also indicates that the process can be streamlined by standardizing the inspections and making them more user-friendly for those who perform them. Digitizing self-inspections would contribute to this, but there are challenges in implementing digital tools. Individual technical skills and the company's resources, opportunity for education, and attitude are factors that greatly influence the success of using digital tools.
