3D BIM – designing of constructions

3D modelling using BIM technologies differs fundamentally from traditional two-dimensional CAD design.

The key distinction is that CAD models operate with lines and planes representing elements of a future building, whereas a 3D model works directly with volumetric elements such as a wall, window, or air duct.

Each building element is characterised by sets of parameters describing it — for example:

• Geometric (dimensions, volume, etc.)

• Physical (thermal conductivity, density, etc.)

• Spatial (position, relation to other elements)

• Visual (appearance, finishes)

Thus, a 3D model is essentially a database of building elements and their interconnections, while 3D design software visualises the contents of this database.

Although this approach may seem more complex, it enables results unattainable with traditional methods:

• Complete correlation between graphical representations, parameters, and related specifications

• Management of elements through parameter programming (parametric modelling)

• Automatic detection of design clashes at the planning stage

Clear Advantages of the 3D Approach

• Faster preparation of design documentation

• Higher accuracy of design solutions

• Elimination of up to 90% of errors in structural and MEP design

• Rapid implementation of project changes

• Ability to integrate the building model with other software (e.g. cost estimating or project management tools)

At VS Project, 3D modelling is carried out by a coordinated team of skilled specialists. Our dedicated servers, workstations, and advanced software make project delivery highly efficient and ensure design solutions are consistently optimised.
