Theoretical and Methodological Bases for Implementing BIM Technologies in Construction Companies: Essence. Characteristics. Economic Efficiency

Abstract

The theoretical concepts and methodological characteristics of implementing BIM technologies in construction companies have been defined. BIM is an information modelling of a construction object, which involves the collection and processing of all information about a building with all its interconnections and dependencies, when the building is considered as a single object. It should be noted that when analysing the definitions of BIM, it is possible to come to the conclusion that it is necessary to make a clearer distinction as to what type of object is meant. Thus, there are some definitions that refer directly to the building model (Building Information Model), the building lifecycle process (Building Information Modelling) and the entire investment and construction process system (Building Information Management). It is pointed out that the traditional approach to design is based on two-dimensional models – plans, drawings and paper documentation. In contrast, Building Information Modelling (BIM) technologies add new aspects – construction plans, time and costs. These can be presented in any convenient form using an information model of the object in virtual reality. The short and long term benefits of using BIM technology in the construction industry are analysed in this article. It was noted that BIM goes beyond standard CAD systems as it allows to create three-dimensional models, known as 3D models, as well as models defined as 4D, 5D, 6D and even 7D. An automated project management system is described on the basis of three elements: the structure of project activities, the structure of resources and the matrix of resource allocation to project activities. In an automated system that ensures effective project planning, control and execution, these elements form a project management model. However, effective cost management throughout the project lifecycle is crucial to the successful implementation of the information system and maximising its benefits to the organisation. According to the authors, the overall cost-effectiveness factor of using BIM technology is determined by several factors: reduction of the overall level of project risks due to proven, accurate and optimised design solutions for engineering systems; reduction of construction time and construction costs as a result of reducing the number of errors in installation and use of materials; improvement of the quality and efficiency of building use will help reduce the negative impact on the environment. The conclusions emphasise that the successful implementation of BIM technologies in a construction company can lead to economic efficiency through an increase in labour productivity, a reduction in the cost of resources and materials, as well as an improvement in the quality and safety of construction processes. In addition, using BIM can help improve the quality of buildings and optimise the use of resources, helping to reduce environmental impact. In fact, BIM is a significant cost driver through this comprehensive approach to project management in construction.
