The Concept of a System Supporting the Acceptance of Flats using BIM

The aim of the article is to present a system supporting the technical acceptance process of flats in multi-family buildings based on a plugin to IFC viewer and BIM model. A system based on a plugin for a free IFC file viewer - BIMvision was shown. The system is aimed at supporting the identification of defects in individual rooms, assessing their significance along with estimating the time and cost of defect repairs. Then, the plugin allows to collect and add descriptions of the acceptance or non-acceptance of a building element in the IFC file of the building BIM model. The system is based on historical data on the occurrence of construction defects, which facilitates the identification of defects during commissioning. A helpful module is the chatbot module, which suggests where and what defects occur most often after asking a series of questions about the type of object, rooms, their location in the building and etc. The result of the plugin activities is also the planned time of removing defects from the database created as a result of measurements of the time of works on the construction site and the planned cost from the database of costs of removing defects. The article presents the concept of such system along with an explanation of the operation principles all its individual modules.
