Abstract
This paper presents the use of tools and approaches of system dynamics in the analysis of the efficiency of BIM tools implementation in relation to the management and planning of investments in the construction sector. The dynamic model based on the approach of system dynamics allows to simulate the impact rate (range) of BIM implementation in strategic investment decision-making in the construction sector. Based on the analysis, the key parameters critically affecting the large construction investment projects are determined. The proposed model is implemented as a submodel in the dynamic model designed for potential refinements in the strategic planning of the extent of investments into projects of civil infrastructure of the Czech Republic. The model allows to test different strategies in the virtual world before their implementation. The prediction of future developments based on the proposed model allows to streamline planning and decision-making processes.
Highlights
In countries of the European Union as well as in other states outside this sector, BIM has been more and more involved in infrastructure projects
The advantages of BIM are undeniable, and in many countries, they are considered so significant that they are mandatory for public tendering – Denmark, Norway, Netherlands, Finland, and the United Kingdom
- Training and resource costs will decrease over time, but there will be a step-up increase in costs in the initial phase of BIM implementation [4]
Summary
In countries of the European Union as well as in other states outside this sector, BIM has been more and more involved in infrastructure projects. BIM is a construction modelling process involving comprehensive information and information flows It includes a 3D model that represents a physical and functional object with all its features and an open database with information about the construction that is shared by all stakeholders [1]. - early detection of collisions and errors in project drafts - elimination of errors in production due to poor quality of projects - better planning and coordination on construction sites The benefits for investors are often mentioned as follows: - adequate and appropriate information for assigning constructions - better controllability during construction - better decision-making and project management thanks to better-quality data available in time - reduction of information noise from poor communication between project stakeholders - reduction of time and costs - sufficient amount of information for the entire cycle of the project – especially in the operation phase
