Hello Schependomlaan

As many of you in the BIM innovation community noticed, Stijn van Schaijk posted a huge amount of public available BIM data on github. Gigabytes of data including IFC data, BCF, pointclouds, schedules, log files, etc. are open available for R&D and educational purposes.

The message in to import Schependomlaan dataset

The GUI has a new feature to automatically import the whole dataset into your BIMserver for demo and testing purposes.

Schependomlaan after import

Recents weeks we’ve been using the dataset to perform some optimisations on the usability of and BIMserver. We’ve noticed that multiple aspect models didn’t perform as we expected and we updated the API of BIMserver to better facilitate this in the viewers.

Testing of the new setup with IfcOpenShell, and BIMserver show remarkable performances. Loading the whole dataset with all 49 aspect models over a home internet connection fully loads within less than half a minute.

Testing on localhost shows the complete dataset in around 10 seconds which proves the limitation is in the internet connection.

We are excited about this and are looking even more forward to the new version of BIM Surfer. The BIM Surfer V2 is well on its way with a much leaner and stable API, an MIT license and much more features for improved usability.


We are stoked to see more and more open source tools of such high quality complementing each other. The activity on github, the release of the Schependomlaan and the growing use of BIMserver prove that BIM users are still seeking innovation. We are happy to contribute to that 🙂

New version of BIM Surfer and integration in BIMserver platform

The BIM Surfer project is, just like, part of the open source BIM collective. It is developing an open source WebGL viewer for BIM models based on open standards (for now only IFC). The project was an initiative from our team, but created by Rehno Lindeque. Due to several reasons there was not a lot of progress at BIM Surfer, until some guys from Vienna picked it up. During the Google Summer of Code students worked on improving BIM Surfer with cool new features. The most visual ones are the two sliders. You can see all about it in de youtube movie below. There are also numerous other improvements. Read all about it on github.
The team, in close collaboration with MOST and TUWien, is working hard on the integration of this new viewer with BIMserver. We are using the new JSON interface to interact with BIM Surfer and load the objecttypes one by one to speed up the loading time. More info will be available in our new beta release which is coming up in a couple of weeks.

UPDATE November 13: Integration with BIMserver platform.

The team has intensified the communication between the open source BIM Surfer viewer and the platform. The ‘get model from server’ now works, and there is much more user feedback with progress bars and partial loading of models. Have a look at the video above.

Integrated Clash detection

As you guys know, the BIMserver team works very close with the guys from TNO in the Netherlands. A year ago this resulted in a special client side IFC viewer with an ‘open from server’  button. In the 0.8 release we integrated the IFC Engine DLL that makes it possible for the BIMserver to export to CityGML, Collada, Google Earth, and more….

Today we announce a new feature of the BIMserver that is a result of our cooperation with TNO: integrated Clash detection!

The 0.9 release of the BIMserver will have the ability to check your model for clashes. This means you can check a submodel (two walls modelled by the architect clashing) or even the merged complete model (to check if a pipe that’s modelled by the HVAC modeller clashes with a wall that is modelled by the architect).

This feature is seen as a key feature for working with BIM. The open source BIMserver is proud to offer this feature to our users. We will keep you posted on the details and the release date.
