<p class="MsoNormal">As part of installation efforts related to the new helium recovery system, contractors will be doing some hammer drilling early next week.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">This work will include drilling 1/2" dia. anchor bolt holes into the floor of the future gas collection room 1101C.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">These anchor points will secure rack systems that hold the medium pressure gas tanks and the ambient pressure gas collection bags that are part of the new system.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The attached PDF shows the work zone on first floor and a projection of this zone to the floors above and below.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Occupants may notice noise or very minor vibrations above, below, or adjacent, to the work zone.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Drilling will be intermittent and will take place according to the pace of the rack installation work on Monday, Tuesday, or Wednesday of next week.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Labs who are concerned about vibration can contact the facility team to obtain a more precise time for drilling.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">It is expected that this work will have no significant impact and will be largely unnoticed by most occupants.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">However, labs with high sensitivity to any level of vibration should plan accordingly.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Flexibility exists to reschedule this work if any high-sensitivity lab campaign currently underway requires a delay.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">A 3-D rendering of the gas bag room showing the warehouse racks, the gas bags, and the medium pressure tanks can be found on page 2 of the attachment.<o:p></o:p></p>
