Argonne Facilities Management Services will begin renovations of the APS Building 401 Plaza on August 27, 2018. Total construction is scheduled to be completed by mid-November 2018, with final landscaping done next spring. This renovation involves a redesign that will decrease the amount of plaza concrete and add green space; these changes will enhance the aesthetics of the Building 401 entryway and reduce maintenance issues. The design of the plaza takes into account the desires of employees and users who participated in an online survey.
