At the Saint Petersburg State University of Architecture and Civil Engineering, within the framework of the conference “BIMAK-2026,” there was a section “Digital Restoration of Cultural Heritage Objects.” Its topics were issues of applying BIM technologies, laser scanning, and digital models in the preservation of the historical environment.
The moderators were I. O., head of the Department of Geodesy, Land Management, and Cadastre of SPBGASU.Yana Volkovaand General Director of LLC “RUSEKO-STRLOYPROEKT”Alexander Lapygin.
From data to knowledge: a systematic approach to inheritance
Alexander LapyginHe delivered a keynote report in which he identified one of the main problems of the industry – data loss at various stages of the lifecycle of objects. “It is necessary to interrupt the data loss cycle and learn to transmit it throughout the entire lifecycle of the object, forming digital twins accessible for subsequent use,” he noted.
According to the expert, despite the availability of modern technologies, the key barriers remain the absence of a regulatory framework for data transmission, lack of infrastructure to handle large volumes of information, and insufficient interagency interaction.
Alexander Lapygin paid special attention to the problem of cloud point detection: since the data volume for a single object can reach several terabytes, this requires significant computational resources and systematic organization of detection.
The speaker emphasized that the digital model of a cultural heritage object should be considered as a multilayered system, including not only geometry but also historical, legal, and operational context.
Practice: TIM-modeling and real projects
The applied aspect of the work was told by the representative of LLC “ASK-Nord”Ivan Krivorotenko,presenting the report “BIM modeling algorithms and workflows using object examples”.
He detailed the organization of project activities within the company and noted that the key tasks are systematizing large volumes of data, establishing effective interaction between architects and modelers, and creating internal methods for working with unique objects.
The speaker noted the complexities of modeling cultural heritage objects, where there is no standardization: “Each object is unique, and standard approaches do not work here – it is necessary to adapt processes for a specific project.”
As examples, he demonstrated digital models of the roofs of the Main Headquarters in Petersburg, the skete of the Solovetsky Monastery, and the Aleksandrovsky Compound.
The speaker noted that in some cases, TIM-modeling becomes the only way to collect scattered data into a single system and obtain a holistic representation of the object.
Other section speakers
The following also participated in the work of the section:
- ÂDmitry Cheglov,Computer graphics artist, publicist, expert in CAD and DCC solutionsÂ(remote) with a report on the experience of reconstruction and visualization of historical objects;
- Oleg Chernetschenko,Representative of LLC “B.C.C.”, on the topic of document storage in paper and digital form;
- Alexander Vysotsky(Vysotskiy consulting), which talked about the implementation of projects for digital models of cultural heritage objects;
- Andrey Chumanov(“Sisoft Development”), whose report was dedicated to modeling elements of wooden architecture;
- Ivan Kushnir(LLC “RV”), who spoke about 3D scanning in the restoration of architectural monuments;
- Sharip Isaev(Saint Petersburg Polytechnic University), a presentation dedicated to TIM support for cultural heritage preservation.
Results
The section showed that digital restoration is moving to a new level: technologies allow creating highly accurate models of cultural heritage objects, but their effective application requires a systematic approach, regulatory framework, and the development of data infrastructure.
Participants emphasized that it is precisely the integration of digital solutions into restoration practices that will ensure the preservation of historical heritage in the long term.
In 2026, at SPBGASU, within the framework of the program 08.03.01 Construction, admission opens for a new profile –“Restoration of buildings and structures”, aimed at training in-demand restoration engineers. The educational program RZS in most disciplines relies on modern technologies of information modeling, fully ensuring the acquisition of the appropriate competencies, including 3D modeling of restoration objects, information technologies in structural and calculation solutions, engineering and environmental life-support systems of objects, laboratory studies and field surveys of OKN objects.
