Forecasting Time between Problems of Building Components by Using BIM

Because the conservation of buildings constructed during Japan's period of high economic growth is now an urgent problem, this paper reports on the development of a method of forecasting the time between problems of building components that integrates building information modeling (BIM) data and building repair records in order to enable more effective and strategic facilities management. In addition, because numerous buildings and facilities are suffering from worker shortages, thus making efficient management and maintenance essential, it is necessary to gain an understanding of how the conditions of components in a building change over time. To that end, building models were created using building blueprints and BIM data was extracted, which was then used in our calculations. Attempts were also made to calculate time between problems of building components via multiple regression analysis. In this process, explanatory variables were collected from BIM and repair record data.
