DESIGN USING INNOVATIVE BUILDING INFORMATION MODELING (BIM) TECHNOLOGY, ALSO KNOWN AS INFORMATIONAL AND PARAMETRIC 3D MODELING.
The distinctive feature of this approach is that any design object is presented in the 3D model, which is the exact digital copy of the underlying object. Final model is not a mere combination of ambiguous picture elements, but rather a detailed description of its components: concrete, brick, reinforcement bar, embedded fitting, channel bar, airline, valve, etc. In addition, each element of the model has its distinctive characteristics, such as model, dimensions (diameter, section, length, area, volume), quantity, and weight.
As a result, such modeling fully imitates the construction process – digital model is assembled by parts from its components, just like on the construction site.
Digital model contains full information about the object, its components and construction parameters. Software enables users to observe and analyze even the smallest elements. One can take a look at the digital copy of the reinforcement bar, have information on its model, diameter and unit weight, or determine the exact location of a particular valve or pipe including its technical parameters.
Multifunctional 3D model not only provides the user with the realistic visualisation of the object, which grants more transparent and practical assessment of the construction process, but also allows the stakeholders to understand the construction principle and how it aligns with other elements in the project. Model easily presents 2D information as well – software allows to convert 3D model into regular 2D working drawings which are later used in the construction cycle.
BIM provides valuable opportunities to the stakeholders. It decreases operational errors, eliminates geometrical discrepancies and allows for more control of the designed elements due to informative 3D presentation. Since working drawings are generated from 3D model, all amendments in the original model are automatically reflected in the working papers. It also opens up new opportunities in the coordination of adjacent sections. The entire construction process becomes more transparent and coherent with more efficient and precise cost control.
Finally, BIM model provides great support and help in management and maintenance of the building on the later stages of the project.
