All BNC Users: A vibratory roller will be utilized to backfill the basements from the demolished student housing which could cause significant vibrations for research. Backfill work will start in front of the center and move west. Hopefully vibration will decrease as the vibrator roller moves farther away from the center. Thank you for your patience and understanding regarding this Purdue Physical Facilities Construction project. Please contact me if you have any issues.

This is part of the Innovation and South Street project. The demolition is expected to continue for approximately 3-4 weeks. The contractor will be working from 7:00 am until 5:30 pm Mon - Fri. It is possible that the BNC may experience vibration during this demolition process. Please be aware of this possibility and organize your work accordingly. Also, please notify me at mvoorhis@purdue.edu<mailto:mvoorhis@purdue.edu> if you experience any vibration issues in your research as a result of this demolition. Thank you in advance for your understanding during this Purdue University Physical Facilities (PUPF) project. From: Denecke, Jacob M Sent: Wednesday, March 08, 2017 1:37 PM To: Voorhis, Mark L. Subject: PVIL Demolition | Next Week Look Ahead Mark, Per our discussion, here is a look ahead for next week: We expect that heavy demo will commence on or after 3-13-17 at the far East end in front of Birck and will progress East to West toward Airport road. The buildings are masonry and concrete floor plates on bar joists and will come done easily. In the process of bringing them down it is possible that large sections of masonry wall or the floor plates will impact with the ground causing vibrations. The work hours will be 7 am to 5:30 pm M-F and the possibility of Saturday work as well. Within each building is a slab on grade and also a basement which will have to be demolished and could also cause some vibrations. The basement areas and utility trenches will have to be backfilled in lifts and vibratory compaction equipment will be used and will cause vibrations. We are currently erecting silt fence and other erosion control measures and installing tree protection fencing and other site prep, asbestos abatement and utility disconnections from the buildings. I'll send you additional updates as they become available. Please let me know if you would like additional person(s) CC'd on these updates. Please direct all PVIL demolition communication through me. As always, if you have any questions, please do not hesitate to contact me. Best Regards, Jacob Denecke, P.E.
