Vermessung Schubert brings BIM to an Austrian landmark

Task

NavVis partner Vermessung Schubert (VS), a surveying company based in Austria, was chosen for a project where Gumpendorfer Straße station is one of 109 metro stations that are run by Wiener Linien GmbH & Co KG that needs updated building plans and a BIM model. For this particular project, the original plans were paper drawings from 1898.There have been many changes in the time since, including a major renovation that took place from 2006-07 with the aim of increasing station accessibility.

Location

Gumpendorfer Straße Metro Station in Vienna, Austria is a historical landmark that dates back to 1898 and features a curved structure and platforms.

Challenge

The biggest challenge of scanning large projects is having the capacity to capture the data. Gumpendorfer Straße alone encompasses over 2000 square meters. Metro stations tend to consist of large, open spaces and small, tightly packed technical equipment rooms. Both of these are among the most difficult indoor environments to capture. An additional challenge for this type of scan was that metro stations, like other public locations, are often full of people. A project this size results in many datasets, which means that, after the scan, alignment can be a very time consuming task. Furthermore, as-built BIM modeling is challenging because the model needs to reflect the reality. This requires a lot of verification to confirm that the data being modeled is reflecting the current state, especially when a high level of detail is required.
