All,

The core drilling is complete. It went faster than anticipated. All that remains is cleanup, but there should be no more vibration from this work.

Thanks for your patience.

Subject: [Bnc-facility-notice] Upcoming Core Drilling In Brk Cleanroom

All,

The Purdue Masonry Shop will be drilling two (2), eight-inch cores through the cleanroom floor slab on Thursday, 8/15/13. The drilling will be located in the LM chase, beginning at approximately 8:00 AM and continuing until around 3:30 PM. Based on past experience, additional drilling may be needed Friday morning in order to complete both cores.

Please be advised that this work may create localized acoustical and mechanical vibration so plan your research accordingly.

Please contact me with any questions or concerns.

Regards,
