Detailed description

The project assignment was to map the existing site, including buildings (technological units) in the vicinity of the Vír dam. Part of the assignment was the requirement to create BIM models of the individual objects at the LOD 100 level in exterior and LOD 300 in interior, including technological piping.

Creation of 3D Model

‍The Trimble SX10 laser scanner was used to acquire data for the exterior of the buildings, while the Trimble X7 scanner was used to scan the interior. A drone pass added rooftops and rooftop elements to the resulting cloud. The resulting point cloud served as the basis for the 3D model, which was created in Autodesk Revit software.

Objectives and Benefits

The aim is to obtain data in detail according to the investor’s requirements and then create a BIM in high accuracy.

‍

Graphic Benefits

Presentation visualisation of the object as a whole
Suitable basis for design and modelling
Realisation of sections at any location and level of detail

‍

Non-Graphic Benefits

Modelled objects reported automatically (number, dimensions, etc.)
Simple and quick spreadsheets, statistics

Technologies used

Trimble X7

The high-speed scanning station is the latest innovative solution in mapping, engineering, and surveying that provides data visualisation directly in the field. Fully integrated 3D scanning functions form its basis. It allows for data to be exported to standard point cloud formats.

Trimble SX10

The scanning total station is an innovative solution in the field of mapping, engineering, and surveying worldwide, setting new standards for surveying instruments.

DJI Phantom 4 Pro

We use this drone mainly for more precise and less extensive work, or for vertical mapping. It is equipped with a high quality 20 megapixel camera with the ability to record 4K videos.
