All of the listed Facilities Management building windows (Attachment I) will be washed over the course of three (3) years. However, some buildings may have windows washed each year, some every second year and some every third year. The list of buildings to have windows washed inside and outside will be established by Building Services Management at the beginning of each contract year. Each building on the list will have interior cleaning scheduled during the same time period as exterior cleaning is scheduled. Housing (Attachment II) will schedule the buildings to be washed in a given contract year. The schedule will be established prior to annual Commencement, with washing to occur during the summer break. However, special circumstances may require that a building be scheduled more often and may be scheduled during the academic year. Housing buildings host summer conferences, therefore, the buildings will have a schedule for available time slots during which windows may be washed. In the event a building is occupied, a notice must be posted 24 hours in advance of work, and work cannot begin before 9:00 a.m. on that day...
