NEIGHBOR RELATIONS Phase 2 excavation is nearly complete and Pepper continues to utilize the water truck and daily street sweeper to mitigate dust on Woodland Avenue. School day restricted truck hours are once again in effect at the beginning and end of each school day. The School District s 3 rd party Testing Agent continues to monitor the vibration associated with the Phase 2 Demolition and Excavation. To date all readings / results have remained below the allowable threshold to cause damage to adjacent structures. II. PROJECT SUMMARY Phase 1 Schedule Progress Pepper is working through the punch list produced by Wight and Company and expect it to be completed over the next 60 days. Much of the work will be completed on off hours to not disturb school activities. Several activities in the concourse will be completed next summer due to access constraints. Phase 2 Schedule Progress The bulk of the demolition is completed and mass excavation is expected to wrap up during the week of 9/13. Concrete foundations are currently underway working from south to north. The excavator will remain on site through September working with the concrete contractor to perform detailed excavation for the foundation pours. To date contractors have not encountered any existing foundations that will require the underpinning that was required during Phase 1. Conditions will continue to monitored as detailed excavation continues and contractors cut to the depths of the bottoms of the footings adjacent to the existing structure.

3 In addition to earthwork operations, reconnection of utilities along the Tower Building that impacted the Tower Building and the Gaffney Auditorium have continued. This has been a labor-intensive process for both the Subcontractors and the PPS Team. Weather permitting, steel erection will begin around the last week of September. Milestones Upcoming major milestones: September 2016 January 2017 Commence Phase 2 Structural Steel Commencement Start Phase 2 Enclosure Safety There have been two injuries since our last Board Meeting.
