The Importance of Digital Information Models in Design
Posted: Sun Dec 22, 2024 10:40 am
Despite the lack of regulatory requirements from the state, digital information models (DIM) are becoming an integral part of design in the construction industry. They are actively used at all stages of the project, including such an important stage as passing the examination.
In this article, we will consider MegaMade's experience in preparing the CIM for state examination, which usa email list was described by the head of the company's BIM department, Yaroslav Demichev. The report he presented is based on real cases and can be very useful for design organizations working with information modeling.
BIM undoubtedly opens up new possibilities for the design and management of construction projects, and CIM allows you to optimize these processes, reduce the number of possible errors and provide high-quality data for analysis.
MegaMade has been actively working with digital models since 2020 and undergoing state examination with projects completed in the BIM environment, including linear objects. It was this experience that became the starting point for the company to further develop competencies in the field of information modeling.
Problems with the lack of generally accepted standards
At present, there are no unified requirements for digital information models in Russia. Each region, as a rule, uses its own methodological documents: for example, in St. Petersburg, RMD-11-22 is used, which contains the minimum requirements for the CIM. It is mainly focused on area objects and engineering surveys and is practically inapplicable to linear objects.
In addition, government customers often do not have ready-made technical specifications for a digital model. In such cases, designers help to form them using their own templates. In MegaMade, they are specially adapted for customers with different levels of understanding of BIM technologies, which minimizes labor costs for creating a digital model. At the same time, the development of machine-readable requirements is not yet being carried out.
Software Integration Issues
The choice of software depends on the specific tasks set for the team. Imported solutions are more convenient for complex projects with high requirements, while Russian products can be effective for individual design sections.
According to Yaroslav Demichev, their company has been using Autodesk products for a long time, including Civil 3D and Revit. This is due to the fact that at the time of BIM implementation in MegaMade, there were no domestic solutions on the Russian market that met all the needs of designers. Using a single ecosystem of products from one manufacturer simplified the processes of coordination and data exchange.
Today, Russia has solutions such as Renga, Robur, and KREDO. However, their functionality is still limited, especially in terms of working with linear objects. At the same time, these software products have convenient options for detailing models (for example, breaking down point elements into separate structures).
Difficulties of design solutions
Design of linear objects such as roads, utility networks and transport infrastructure is performed with high accuracy and detail. Civil 3D exports routes and profiles in IFC 4.3 format without serious problems, but there are limitations when modeling some utility networks.
Thus, the development of lighting and electrical network models causes difficulties due to the impossibility of specifying several rotation angles without breaking up the pipes. Also, the program does not allow for the correct modeling of some objects, such as lighting supports, due to the lack of their division into constituent elements (foundation, support, bracket, and lamp).
