Problems in the examination of information models
Posted: Sun Dec 22, 2024 8:54 am
Government agencies face numerous challenges and difficulties when using information modeling technologies to conduct inspections. However, specialists are working hard to overcome them. Thus, Sergey Serbin shared practical experience in solving these problems in the Sverdlovsk region at the September BIM breakfast. He also told how the introduction of a digital information model affected the process of state examination of design documentation.
Legislation Review
The expert began his speech with a brief overview of the rules and regulations that govern the field of germany phone number list information modeling of capital construction projects (CCP):
Urban Development Code of the Russian Federation : introduces the concept of an information model of the OKS. It is understood as a set of electronic documents that must necessarily represent design documentation in digital form. It is important to note that the presence of a 3D model in the information model is not mandatory
Resolution No. 331 : clarifies the conditions for the formation and maintenance of an information model. Thus, from July 1, 2024, participants in shared construction are required to maintain an information model. Similar requirements were introduced from January 1, 2022 for state-owned facilities
SP No. 333 : supplements the concept of “digital information model” and establishes that the DIM is a data-rich three-dimensional model
Resolution No. 614: regulates the mandatory supplementation of the information model with a digital information model in a number of cases provided for by PP No. 331
Sergey Dragomirov spoke in more detail about all the intricacies of regulatory documents for the construction industry. Read a brief overview of his speech here .
Among the main difficulties in conducting the examination, Sergei Serbin noted:
Lack of uniform requirements
Despite the effective Resolution No. 614, which assumes that the minimum requirements for the CIM will be developed by the Ministry of Construction of Russia, there is currently no such list. The project exists, but it has not yet been approved.
Therefore, now each customer forms individual requirements for the CIM depending on their tasks and preferences, which complicates the process of verification and validation of the model, since the requirements can differ significantly. Because of this, experts receive a double workload, especially at the stage of checking the compliance of the CIM and 2D documentation.
Increasing the complexity of the examination
This creates a double labor intensity of the examination: when simultaneously examining 2D documentation and the information model, experts have to conduct an additional check for compliance with the 2D and 3D models. Despite the possibility of automated verification of model attributes, the process takes time and cannot completely replace manual verification. The expert cannot rely on the results of the automatic verification and is forced to personally confirm the model's compliance with the established standards.
Conflicting demands
Customers sometimes require designers to develop the CIM in more detail, for example, for the utility networks section. As a result, a conflict arises between customer requirements and the standards of PP No. 87, which regulates the level of detail in design documentation. Experts who rely on this document have to adjust the level of detail and take into account the difference between the standards and the actual content of the CIM.
