Construction work on doors in Janskerkhof 13(a) starting march 18th

In order to meet modern fire regulations, the doors in Janskerkhof 13(a) have to be adjusted. The main reason is to buy some extra time to flee in case of fire. So not every door will need maintenance, but mainly those in the hallways and in “technical” rooms. For the basement its scheduled between march 18th and 25th, the other floors might also take a week or so.
The contractor will take the doors outside of the building and do most of the adjustments to the doors outside. The doors will be taken out of the building before 9:00 and might be fitted back next day before 9:00. So you should be safe to run your experiment during regular hours, but don’t be surprised to encounter some missing doors.
