The Building Information Modelling Through Information Technology and Impacts on Selected Circular Economy Performance Indicators of Construction Projects

The building information modeling represents the management of construction projects based on relevant information and work with them. In the era of digitization, it represents a space for modeling information about constructions to implement and increase the digital level in the construction industry as well. One of the goals of implementing new technologies is to improve performance and efficiency. The current situation within the pressure for sustainability and so-called green solutions brings new challenges, but also perspectives on technologies with the aim of increasing sustainability in every phase of the construction project. One of the tools should be the very implementation of these solutions to support the use of information and information systems to support the achievement of goals. Improving performance and achieving goals in circular economy and a higher level of sustainability itself is intended to quantify performance and change. Key performance indicators need to be monitored and evaluated. It is believed that building information modeling can achieve selected performance indicators. Due to the principles of the circular economy, there is pressure to monitor indicators that will lead to an increase in performance and indicators associated with this concept. In the research, based on relevant studies, the key performance indicators of the circular economy in the management of construction projects were determined. Due to the perception of sustainability through economic sustainability, material costs, material consumption, recycling costs, rate of use of recycled materials, waste management costs were monitored. The goal of the research was to quantify the impacts of building information modeling on selected performance indicators within the concept of circular economy. The aim of the research was to analyze the impact of using BIM on selected performance indicators. The research took place in three countries, namely Slovakia, Croatia, and Slovenia. The respondents were the main participants in the construction project. Data processing was based on the search for relationships and dependencies between the rate of use of information building modeling and selected key performance indicators.
