Assignment
An infrastructure tunnel with a length of approximately 1,100 meters and a width of over 10 meters is equipped with a variety of cables and pipes that supply the various buildings above with power, water, heating, etc. A large number of mounting brackets of the pipes are corroded due to flooding. The assignment was to inventory to what extent the brackets are corroded and where these brackets are located. This information will be used in a tender to replace the brackets.

Inspecting with Augmentend Reality

Beecot-Inspect uses Augmented Reality as an interface for inspections. The augmented projection of the model allows you to digitally select a specific object by tapping at it on your screen. This way you are able to link the inspection data to the applicable BIM object. Photos are also linked to the applicable BIM object and the location and viewpoint of the camera are saved as well, so the receiver can open and view the photo in the context of the model. 

Managing the project in Catenda

The output of the inspection can easily be reviewed and managed by the Erasmus project team. All data can be queried and analyzed according to the project management task. High resolution pictures can be viewed in the context of the model. By clicking on the topic in Catenda, the viewer zooms in to the applicable BIM object, which is also highlighted. Linked pictures are presented in the BIM viewer, presented from the same viewpoint as the picture was taken. This allows the project team to review and analyze the project scope from their desk. In the next phase of the project, during the execution by the selected contractor, the project team gets updated in Catenda on a status update of each bracket that was replaced. 

This way they have real time insights in the project progress without the need to go into the tunnel.

Tendering based on inspection output

After the output of the inspection is processed by the project team, it can easily be reviewed by the tendering contractors. All data can be queried and analyzed according to the needs of each contractor. All high resolution pictures can be viewed in the context of the model, in their specific modeling software. The applicable BIM object is highlighted in the native modeling software and the linked pictures are presented from the same viewpoint as the picture was taken. This allows all contractors to review and analyze the assignment as desk research, reducing costly inspection hours by all competing contractors.

Result

This way Erasmus MC was able to create a complete and accurate inspection file. They expect this will ensure them with competitive offers and reduce the risk of out-of-scope additional costs.
