FW: Excavation

All researchers: As you can see by the information in the note below, building vibrations will continue today until 5:30 pm and tomorrow until noon. This is out of our control and was completely unexpected. Please schedule vibration-sensitive work accordingly. My apologies for any interruptions that this has caused and will cause - it was a surprise to all the BNC staff. John John R. Weaver Facility Manager Birck Nanotechnology Center Purdue University (765) 494-5494 jrweaver(a)purdue.edu -----Original Message----- From: Hassenplug, Heather D Sent: Thursday, July 26, 2012 10:49 AM To: Weaver, John R Cc: Skiba, Chris E; Franscoviak, Tony E Subject: RE: Excavation John, I apologize for the vibrations. The contractor ran into a unforeseen condition; the old slab for the generator was 3 foot thick. To put it in perspective, the new slab for the generator is designed at 12". This is causing the contractor to have larger than expected chunks of concrete. The vibrations will unfortunately continue today until 5:30PM and then tomorrow until noon. There should be no more planned vibrations after that. With the nature of construction I can't tighten the window any more than on and off until noon tomorrow. Again I apologize for the vibrations.

It is bad enough that it is shutting down our research - I have had multiple researchers contacting me regarding the vibrations. The problem is timing. They are doing the work at random times during the day - no way for us to predict when the gross vibrations are going to occur. Shutting down research from 7:00 am to 6:00 pm is not reasonable - we need tighter time windows. Thanks, John John R.

I'll let you know what I get back. Thanks for the email. Heather -----Original Message----- From: Weaver, John R Sent: Tuesday, July 24, 2012 10:03 AM To: Hassenplug, Heather D Subject: Excavation Heather - I guess I didn't understand the impact (all puns intended) of the excavation at the Bindley Expansion. I was expecting "standard" excavation work - digging an breaking up concrete. The method for breaking the concrete appears to be lifting large pieces to height, then dropping them. This literally bounces the Birck building. Compounding the issue, this is done at seemingly random times throughout the day. Two questions: First, how long is this expected to continue? (Not the excavation in general, just the dropping of the large concrete pieces.) Second, would it be possible to break up the concrete during a discrete period of time that I can communicate to our users. Right now it is at random intervals between 7:00 am and 6:00 pm. Anything that can be done to help would be appreciated. If nothing can be done, we will live with the situation. Thanks, John John R.

Facility Shutdown Notice and PM Shutdown Week
by Weaver, John R 24 Jul '12

24 Jul '12

Due to the electrical tie-in for the Bindley Expansion Project, the Birck Nanotechnology Center will "go dark" on Thursday, September 6, 2012. This means that there will be NO POWER in the building, no air conditioning, etc. Lighting, computers, etc. will be off. NO ONE SHOULD PLAN ON OCCUPYING THE BUILDING DURING THIS TIME - alternative arrangements should be made. Because of this mandatory shutdown for the construction work, it has been decided to move the semiannual PM shutdown to the week of September 4, 2012 (Labor Day Week). There are two major advantages to this decision. First, we will have only one shutdown that will impact research. Second, the length of the total shutdown duration will be shortened by one day due to the combination of the PM shutdown with the electrical shutdown - again lessening the impact on research. Please note that during the power outage cleanroom temperature and humidity are expected to rise, and there will be no exhaust in the facility. For these reasons, NO BEAKERS, covered or not, can contain any chemicals - all chemicals must be in sealed bottles in the chemical storage cabinets. Also, it is strongly recommended that no photoresist-coated wafers (including patterned wafers awaiting etch) be kept over the shutdown. Patterning issues should be expected if wafers are subjected to the high temperature and humidity conditions. More details will follow, but currently the plan is as follows: Monday, Sept. 3, 2012 (Labor Day): Hoods must be EMPTY by 11:00 PM. Tuesday, Sept. 4, 2012: Semiannual PM begins. No hood work. Cleanroom and laboratories closed. Wednesday, Sept. 5, 2012: PM continues. Power down computers, critical systems at end of day. Thursday, Sept. 6, 2012: BUILDING CLOSED. NO ELECTRICITY IN BUILDING. Expect 7am-7pm shutdown of electricity. Building systems will begin power-down at 4:00 am and we expect them to be back on line by 10:00 pm unless unforeseen problems arise. Friday, Sept. 7, 2012: Semiannual PM continues. No hood work. Cleanroom and laboratories closed. If all goes well, it is expected that we will reopen the cleanroom and laboratories by 4:00 pm on Friday, Sept. 7, 2012. The processing equipment may be operational subsequent to that time - check Coral for equipment availability. Note that it will most likely take until sometime on Monday for the ultrapure water to recover its purity level. Thank you in advance for your patience and support during this necessary power outage and maintenance shutdown. John John R.
