"The construction information classifier, formed on the basis of ISO 81346, is the language of a new technological order," this is how VDC Director and Advisor to the State Duma of ASKAO Viktor Klepa began his second speech at the summer BIM forum. In a short report, he answered questions about how exactly the KSI data is used, what it affects and what its shortcomings are. Read an overview of korea phone number his main points in this article.
Reducing transaction costs
To explain the impact of the KSI on the construction industry, Viktor Klepa, referring to the Dean of the Faculty of Economics of Moscow State University A.A. Auzan, first reminded the audience that more than 50% of the costs in our economy are transaction costs. These costs are associated with such factors as the transfer of ownership, risk transfer, rechecks, etc., which ultimately do not bring any added value.
One of the main reasons for the occurrence of costs is the lack of clear agreements on the classification and coding of information, which is why managers are forced to repeatedly recheck decisions made in investment and construction projects. KSI can also help eliminate this problem and transform unproductive costs into added value. But what methods are supposed to be used to carry out this activity?
To begin with, the expert reminded the BIM forum audience of the history of the development of the KSI, which is 55 years old this year. In 1969, during the construction of the Bushehr Nuclear Power Plant in Iran, the German specialists responsible for it created the AKS system (AKZ in German) for designating components and equipment at thermal power plants. It was later transformed into the KKS system. Then, in the 2000s, the RDS-PP reference designation system for energy facilities appeared, which was transformed into the ISO 81346 series of standards, which Viktor Klepa designated as the Reference Designation System (RDS) and only the basis for building a classifier.
Errors and problems of application
Victor Klepa identified three errors in the application of the Construction Information Classifier:
Incorrect translation of terms in the "Components" table, which distorts the perception of information and creates the risk of erroneous classification of the object
The table "Construction Products" is not based on the Reference Designation System (RDS). That is, construction products such as walls, columns, doors, etc. have been classified based on new units.
Violation of class and subclass definition rules due to use of component properties instead of faceted classification structure
Working system based on the KSI source
"When we talk about building products, we constantly operate with partitive relations: we insert a window into a wall, we put the wall on the foundation, we put the floor on the supporting structures, we do the reinforcement inside the wall. That is, for us the most important thing is what goes into what," the expert noted, explaining that when forming a classifier of building products, it is precisely such partitive relations that need to be taken into account in order to reproduce the logic of assembling the structure.
