All,
Facilities will be conducting some work at each entrance of the ILSB over the early summer to address mechanical access panels in the ceiling. The plan currently will involve closing access to the east entrance, facing Physics, for two weeks +/- and then replicating similar work in the west side / quad facing entrance.
There is nothing you need to do at the monent other than be aware of the plans. I'll add additional information as the plans evolve.
