The Building Information Model (BIM Information Model) – is:
- well-coordinated, coherent and interconnected,
- calculable and analysable,
- having a geometric reference,
- suitable for computer use,
- numerical information that allows necessary updates about the object being designed or already existing, which can be used for:
- making specific design decisions,
- creating high-quality project documentation,
- predicting the operational qualities of an object,
- preparation of estimates and construction plans,
- ordering and manufacturing of materials and equipment,
- building construction management,
- management and operation of the building itself and technical equipment throughout the entire life cycle,
- building management as an object of commercial activity,
- designing and managing the reconstruction or renovation of a building,
- demolition and disposal of buildings,
- other goals related to the building.
In other words, BIM – is all information about an object that has a numerical description and is properly organized, used both at the design and construction stage of a building, and during its operation and even demolition.
Using a building information model makes it much easier to work with the object and has a lot of advantages over previous design forms. First of all, it allows you to put together in virtual mode, select the components and systems of the future structure created by different specialists and organizations, calculate, connect and coordinate them,” at the tip of the pen “check their viability, functional suitability and operational qualities in advance, and also avoid the most unpleasant thing for designers – internal inconsistencies.
Unlike traditional computer-aided design systems that create geometric images, the result of building information modeling is usually an object-oriented digital model of both the entire object and its construction process.
Most often, the work on creating an information model of a building is carried out in two stages.
First developed some blocks (family) – the primary elements of design that are appropriate as construction products (Windows, doors, slabs, etc.), and fittings (heating and lighting appliances, elevators, etc.) and much more that is directly related to the building, but is outside the scope of the construction site and during the construction of the object is not divided into parts.
The second stage is modeling what is being created on the construction site. These are foundations, walls, roofs, curtain facades and much more. At the same time, it is assumed that pre-created elements are widely used, for example, fixing or framing parts when forming the curtain walls of a building.
Thus, the logic of building information modeling, contrary to the fears of some skeptics, has left the incomprehensible area of programming for designers and builders and corresponds to the usual understanding of how to build a house, how to equip it and how to live in it.
This greatly facilitates and simplifies the work with BIM for both designers and all other categories of builders, and then operators.
As for the division into stages (first and second) when creating BIM, it is rather conditional in nature – you can, for example, insert windows into the modeled object, and then, for new reasons, change them, and the project will use the already modified windows.
The main advantages are public health consultancy the information model of the projected object built by public health consultancy specialists then becomes the basis and is actively used for creating working documentation of all types, developing and manufacturing building structures and parts, completing the object, ordering and installing technological equipment, economic calculations, organizing the construction of the building itself, as well as solving technical and organizational and economic issues of subsequent operation.
The information model exists for the entire life cycle of the building, and even longer. The information contained in it can be changed, supplemented, or replaced, reflecting the current state of the building.
Such an approach in designing, when an object is considered not only in space, but also in time, that is, “3D plus time”, is often called 4D, and “4D plus information” is usually referred to as 5D. Although, on the other hand, in a number of publications, 4D can be understood as “3D plus specifications”.
