Site in Velké Meziříčí

The construction company’s headquarters are located in Velké Meziříčí, and the scope of the project was to map the existing complex. The assignment included a requirement to develop a BIM model at LOD 200 for external structures. Data collection was performed using unmanned aerial vehicles (drones) and terrestrial laser scanning.

Creation of a 3D model and BIM

The site was surveyed using a DJI Phantom 4 PRO drone at a ground resolution of 2 cm/pixel. A digital surface model was created from the aerial imagery data in the JTSK coordinate system and the Bpv elevation system. The acquired data was supplemented with facade scans using a Trimble SX10 device. The resulting point clouds were processed and digitized using Autodesk ReCap and REVIT software.

Output data format: RVT

Objectives and Benefits

Our objective is to collect 3D data and create 3D information models of existing structures in accordance with BIM standards, at the level of detail specified by the client. The delivered outputs serve as a basis for design work—direct integration with the model is achieved through native formats or by exporting to the IFC exchange format, which is used as a universal format for data transfer between software applications.

Graphical advantages

• clear visualization of structures and utility networks (both graphical and descriptive information)
• better orientation and visualization for the client (effective handling of project changes)
• ability to create 2D drawing documentation
• additional modifications and updates to the model are automatically reflected in all drawings
• Easy comparison of the actual state against the project
• Ability to view the model through VR glasses for a comprehensive visualization

Non-graphical advantages

• Automatic reports of elements from BIM models (quantity, dimensions)
• imple and fast tabular reports, statistics
• Ability to connect to facility management (for use by the investor)
