Facade elevation of a listed industrial building

Refurbishment of a listed industrial building in Magdeburg

3D laser scanning was used as a surveying method for the listed renovation of an old industrial building in Magdeburg. As part of the renovation and conversion work, 22 loft apartments are to be created in the complex. In order to renovate the façade in accordance with the preservation order during the conversion work, detailed, highly accurate plans of the façade to scale are required. Due to the limited space available, the 17 m high facade can only be mapped using a non-contact measuring method.

The smallest of the three facades, the east facade, has several facade jumps and sloping facade parts, which increased the effort of surveying and evaluation.  With the help of laser scanning, the facade details, such as window openings and wall protrusions, could be captured with high accuracy.

Orthophotos were automatically generated from the laser scanning survey results using PointCab Origins. Using the true-to-scale PointCab Origins images, the data was imported into Geograf within an hour. This resulted in detailed orthophotos and structured, digital 2D plans of the facades, including the cracks in the east facade. Modeling can now be carried out in the generated views and sections of the 3D CAD model, which simplifies planning for the renovation and conversion work.

The facts again at a glance: The three facades of the building complex were captured by laser scanner. The data was evaluated with PointCab Origins and Geograf at a scale of 1:50. A total of 25 laser scanner locations were used to measure the 1,720 m² of the facade. Only one employee was needed for the survey, which took only 5 hours. One of the advantages of PointCab Origins was the fast generation of the othophotos. Within one hour, 3 GB of data could be processed. This resulted in true-to-scale and detailed images. Reading in and further processing of the data in the CAD system Geograf was possible without any problems. Thanks to the quickly generated Othofotos, the evaluation in Geograf was a piece of cake. In total, the project was completed within 35 working hours from the first scan.

As-built documentation of an old house

Preparation of remediation concepts - Swiss Canton Ticinio

As part of a project by Pastorelli SA, an old house in the center of a village in the Swiss canton of Ticino was to be surveyed. Thus, detailed plans of the building were to be created. The purpose of the project was to be able to use the plans to create renovation concepts in the ArchiCAD software. Since there were no current and reliable plans of the building, a modern measuring method was used: 3D laser scanning.

The engineering firm Pastorelli SA, based in Lugano (Switzerland), used the FARO Photon 120 laser scanner for this purpose. Three facades and the four floors of the house were recorded. The scanner was placed inside the house to scan the basement, the roof and the two floors in between. Outside, it was set up to capture the facades. This resulted in a total of 29 scans within 6 hours. Three employees were involved in the process. The created scans were registered with the software FARO Scene. The point clouds were merged into one large point cloud. This point cloud contains all measuring points of the object.

With the help of PointCab Origins, four floor plans, three façade plans and 20 sections could be extracted automatically. The orthophotos could be exported for use in various CAD systems. Since Pastorelli SA’s client wanted to perform the renovation plans in ArchiCAD software, PointCab Origins was an excellent solution for preparing the data. It was possible to quickly generate the required plans automatically and then create any sections. In this way, the data could then be easily used in the ArchiCAD CAD system. Finally, the data set obtained was conveniently handed over via USB stick.  In total, the data processing took about 8 hours.
