Study of preparatory activities on using BIM-technologies in the medical enterprise design

Introduction. When designing buildings and installations, Building Information Modeling (BIM) is spread more and more widely. The adoption of national and international standards and classifications is of great importance for the implementation of information technology. Application of the BIM-technologies for constructing public buildings, in the first turn, medical ones, seems to be very promising. The paper discusses the problems of developing indigenous parametric blocks (families) and preparatory activities in using the BIM-technology. Materials and methods. One of the information technology tasks is to develop equipment specifications and transfer them through the technological chain of the construction facility life cycle. The creation and application of classifiers are necessary to prepare for using the BIM-technologies. Results. A project of an academic health science centre with an extensive equipment range is analysed. The project of a modern medical building contains a description of several hundreds of specific medical equipment types. The specifications should contain information, including denominations and quantities of the equipment units, data on overall dimensions and weights of the units, connection interfaces to the power supply, water supply, water drainage. When creating parametric blocks, the international classifiers Uniclass-2015 and OmniClass are often used. However, they do not cover the necessary equipment range and contradict the domestic practice of purchasing equipment and services for state demand. Conclusions. The cost of preparing for the design process as creating parametric blocks can make a total of tens or hundreds of man-days that should be taken into account when planning design activities. In terms of procurement for state and municipal demand, it is necessary to make design specifications following the available range of medical equipment.
