The ESSS has two rooms on the top floor of the ASB. The ESSS office is in ASB 10868 and the engineering common room is in ASB 10822. Note that one of the doors into the common room requires the code and certain doors in the ASB require key fob access.
Due to construction in the ASB which started in Spring 2020, the location of the ESSS office and the common room is likely to change and current access is restricted. As of the last update we were given, the common room has no walls.
