Work is commencing on the
enclosure for the Acid-Waste Neutralization (AWN) system. While the
impact on any operations at BNC should be minimal, there will be some
activities early in the project that could cause some vibration.
This activity will take place at
the southwest corner of the BNC. This work will be done on concrete that is not
connected to the BNC – any vibration would be transmitted through the
ground. The closest vibration-sensitive equipment is the Vistec e-beam
writer, about 35 feet away. Next would be the Titan TEM and the Raith
e-beam, both about 175 feet away.
Weather permitting, the work will
begin next Thursday, 22 April 2010, and last until the following Wednesday, 28
April 2010. Most of the activities will involve saw cutting, which should
have no vibration impact. In some cases, however, a jackhammer will be
used, and in all cases a backhoe and/or front loader will be used for the
concrete removal. A more detailed schedule follows.
Work will take place from 7:30 AM
to 4:30 PM weekdays. No work will take place on weekends.
Please contact Mark Voorhis if you
experience any vibration-related issues.
Thank you for your understanding
during this necessary construction effort.
