RetroBIM


RetroBIMDigital Twin for Tunnel Management and Maintenance

RetroBIM – Digital Twin for Tunnel Management and Maintenance

• Digital twin of existing objects (as-built model of the construction including technical

installations), which is

• geometrically verified, and

• does not contain redundant information.


RetroBIM - Motivation

• Collection of all available information about an existing infrastructure

• Connecting various data base information with 3D geometrical model

• Single source of information (truth) for the whole life-cycle

• Shall facilitate tunnel management and tunnel maintenance in a smarter way


RetroBIM Oelbergtunnel – GIS based Facility Management tool



Basic source of information

As built documentation from construction

Scan data



Typical type of information for RetroBIM Models

Greyscale pictures

Images from tunnel documentation

Clearance profile

Clearance profile analysis

Surveying data

Inspection data

Sensor data (IoT / GeoMonitoring)

Geological information

Groundwater information

Link to the maintenance plans

Information about any technical installations
