All, Purdue Shops will be hammer drilling a number of holes into the concrete floor in Lab 1031 tomorrow (Friday) morning between 8:00 AM and approximately 9:30 AM. This is needed in order to anchor a laser curtain frame to the floor. Please be aware that the work will create vibration in east lab wing, especially in the vicinity of lab 1031. Please let me know ASAP if this creates any issues. Thank you. Jeff Kuhn Facility Engineer Birck Nanotechnology Center Purdue University 1205 W.
