Welcome and thanks for contributing to OpenStreetMap.

In this changeset you've added a building that shares nodes with the SRL East way.

https://www.openstreetmap.org/way/1446183081/history/1

As the buildings on the surface do not connect to or are attached to an underground construction way in anyway, they should not share nodes with each other.

I've removed the nodes from the SRL in https://www.openstreetmap.org/changeset/173955146.

Please take care not to attach buildings nodes to the SRL in future.

Also, if you can contact the smart-cities-transport-project-71 organiser and inform them that some mappers keep adding nodes to the SRL, it would be much appreciated. I am unable to find the contact information of the organiser who's responsible for the mapping through the smartcitiestransport website without making an account.
