Organization and management of 4D-modelling processes in construction

Abstract

The study aims to determine the prospects of integrated automation in the management of construction stages and scheduling on the basis of the 4D-modelling concept, which is applied in domestic and foreign practice of capital construction for visualizing the sequence of construction stages. Due to the use of conventional planning tools, the majority of developers fail to meet the established construction deadlines. At present, the construction industry is at the stage of transition from 2D documentation and step-by-step processes of forming a digital model to an integrated schedule based on the concept of 4D-modelling. Within the framework of transitioning to Industry 4.0, the introduction of 4D-modelling in the BIM model will revolutionize the construction industry by integrating these 3D models with additional planning dimensions and cost estimations. The application of 4D-modelling is shown to improve the efficiency of work processes, which were previously associated with a great risk and inefficiency of construction stages. Currently, the application of the 4D-visualization method is at its nascent stage due to a number of barriers and problems, including those related to the reassessment of implementation costs, a search for competent personnel, as well as a lack of integrated models. At the same time, the application of 4D models appears to be a necessary and inevitable transition to a new stage of digital maturity of the construction industry, which allows the subjects of the construction process to effectively visualize construction stages, accurately plan the required resources and optimize communications within each stage.
