When should the primary use be changed from an Office (31*) to Computational Dry Lab/Research Office (261)?

Primary use should be changed when 50% or more of the time can be attributable to sponsored research activities.  When changing the Primary Use from 310 to 261, please be sure to update the Occupants as well.  

Rooms below 50% sponsored research activity should remain with office designation and will be functionalized based on department’s salary and wages (joint use); occupants do not need to be updated.
