Building information modelling is a model-based process of the building’s entire life cycle: construction, use, renovation or repurposing. Although this principle based on exact 3D model has roots in architecture, today it implies almost all infrastructural projects where geodesists actively participate. The advantage of BIM 3D model production is that we can enrich all the information previously collected by laser scanners. BIM technology enables each professional to add information that is specific to his or her profession (processes) – in other words, it leads to a more efficient communication between the contractor and architects, engineers and constructors (AEC), since it gives them the insight and the tools for efficient planning, modelling, building and managing buildings and infrastructure.
Alongside 3D documentation, BIM documentation contains many other information: geodesy coordinates, quantity of elements and materials, element properties (heat conductibility, mass or strength), constructive elements of the object, installation systems (cooling/heating, fire protection, plumbing, drainage…), costs and other information needed to make project documentation. This kind of precise project documentation can reveal possible project errors in time (most often before the construction begins) and ensures low costs and high efficiency. Since it supports sustainable construction, BIM technology already defined the future of construction and set a standard that will be a base for spatial planning in the years to come.
