Sergey Bovteev, associate professor at the SPbGASU Department of Construction Management, developed a method for using 4D modeling for the calendar construction of facilities and their complexes. This research was carried out as part of a grant competition for research work by SPbGASU scientific and pedagogical workers in 2023, grant number - 4-NPR-23.

“The construction of any facility must be carried out in accordance with the calendar schedule. This document establishes the list of works, the order of their implementation, the timing of work, as well as resource requirements. I have worked with calendar charts for a long time and I know how voluminous they can be - several dozen A3 pages filled with small font and equally small lines. The lack of clarity when creating graphs leads to numerous errors and inaccuracies, so such documents are often not used properly in practice. At the same time, a lot of specialist effort is spent on creating graphs,” said Sergey Vladimirovich.

Sergey Bovteev is confident that 4D modeling makes calendar schedules more convenient and correct, turning them into the main tool for managing construction deadlines. The author of the study was able to obtain the first practical experience of using 4D models for visualizing calendar charts during the renovation project of built-up areas of St Petersburg in 2014.

To create a 4D model, it is necessary to synchronize the 3D model of the object under construction with the schedule. As a result, all interested participants in a construction project can quickly track the sequence of construction works, visually see discrepancies between plan and fact, and make timely recommendations and comments.

According to the scientist, SPbGASU has been teaching students 4D modeling software since 2018. In addition, students compete at intra-university and inter-university TIM championships, where they successfully complete 4D modeling tasks. Many SPbGASU students find work in this field even at the stage of studying in the master's program. The university also interacts with developers, helping them create domestic software products. Now that foreign companies have left the market, the issue of functional requirements for software is quite acute.

The methodology developed as part of the grant clarifies the requirements for initial data at different stages of 4D construction modeling, allows the use of 4D models to solve problems of planning and managing the construction of facilities and their complexes, and contains recommendations for the implementation of 4D modeling in the activities of design and construction organizations.
