<p class="MsoNormal">At approximately 3:30 am, an expansion joint in the main heating hot water piping circuit ruptured resulting in the loss of heating hot water.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">With this loss of heating water, temperatures in the building have fallen and in some offices reached mid-fifties levels.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Also as a result of this heating water loss, some air handlers shut themselves down by protective circuits that prevent internal coil freezing.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">FOD has been on site since shortly after the rupture occurred and is working to resolve the issues.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">AHU-1 and AHU-3 are currently both online as well as four of the six main exhaust fans.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">AHU-2 is currently offline because the joint rupture occurred internal to this unit and the chamber where this occurred was partially flooded.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">AHU-4 is offline.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">FOD reports that the replacement expansion joint is now installed and re-start of the remaining offline systems will occur early this morning.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">A follow up message will be sent when systems are fully restored.<o:p></o:p></p>
