    BIM: unique opportunities for unique buildings

    Oleg Baranov

    On October 10, a new issue of the Construction Weekly magazine was published, and it contains an article by Oleg Baranov, Deputy General Director of the Metropolis company. In this piece, Oleg spoke about the distinctive features and markers of unique buildings, information modeling of these buildings and the benefits of introducing BIM modeling into the design process.

    "The category of unique objects includes airport complexes, sports and entertainment facilities, places of culture, exhibition and concert halls, administrative, shopping and entertainment centers, which can accommodate over 1,000 people and over 10,000 nearby. The category of unique buildings also includes high-rise buildings - more than 100 meters high, with spans of structures over 100 meters, cantilevers more than 20 meters, deepening of the underground part (in whole or in part) below the planning level of the earth by more than 15 meters, as well as buildings and structures erected in areas with seismic activity exceeding 9 points. For the construction of unique buildings, structures and structural schemes are used with non-standard or specially developed calculation methods or requiring verification on physical models."

    Some of the unique objects in the Metropolis portfolio:


    "Taking into account the saturation of such buildings with utility lines, special requirements are applied to their design to ensure the necessary level of comfort and energy efficiency. In particular, when designing water supply and sanitation systems, the gravitational component is taken into account. In high-rise buildings, an artificial ventilation system is used and it is very important to ensure a comfortable level of temperature and humidity in the premises. For continuous monitoring of the state and functioning of systems, all engineering communications of buildings are connected to the automation and dispatching system.

    As a rule, when designing unique buildings and structures, the development of special technical specifications (STS) is required: justification for the feasibility of developing STS and the missing regulatory requirements set out in accordance with current technical standards; a list of deviations from the current standards and a list of measures to compensate for these deviations; description of the object and its main elements with a statement of design and space-planning solutions; additional requirements must be attributed to a specific regulatory document or its section.

    It also requires scientific and technical support, which includes: forecasting the state of buildings and structures, taking into account all kinds of impacts; forecast of the state of objects located in the construction zone; development of specific solutions to eliminate violations identified during the monitoring of design solutions; development of scientifically based and optimal solutions, participation in the definition of design solutions; development of technical recommendations that are not included in the current regulatory documents.

    Increasingly, high-rise buildings are created using information modeling (BIM), which allows you to perform energy modeling, data analysis, build augmented reality, pre-configure the control system, build an operational model of the facility, and implement cloud services for management and analytics.

    The use of BIM modeling technology also speeds up the design process. One of the important advantages of performing design using BIM is the detection of collisions, i.e. the ability to detect errors in the project resulting from geometric intersections, violations of the allowable distances between elements, logical connections between elements, normalized parameters, etc.

    The Metropolis company has developed and now uses a standard for design work using BIM on the Revit platform, the routine operations of engineers, designers and architects are automated. Templates for creating projects have been developed, a centralized library of families has been organized. A regulation for the interaction of designers to create an integrated BIM model has been developed. As part of import substitution in terms of BIM, domestic software has been developed and is constantly being supplemented with various functions. The most common of them are Renga, nanoCAD, Model Studio CS, but their capabilities are still inferior to the Autodesk Revit software package.

    In 2016, Metropolis completely switched to integrated design using BIM technologies, including architectural solutions. The transition to design using information modeling technology in our company took about a year and required significant financial resources. The return on this investment was ensured by increasing labor productivity and the quality of documentation, receiving a large number of orders that required implementation using BIM technologies.”
