Our HVAC installation company, Semco confirmed this morning that they would be able to return to ILSB on Saturday, 11/9/2019 to perform the additional testing and install additional seals for AHU’s 1A thru 1DE.  This would require 2 of the 4 AHU’s to be shut down at a time for a total of an 8-hour period of time. There will still be ventilation into the building during this time, however fume hood flow will be reduced and the building will be somewhat running a negative pressure.

I'll let you know more details as I get them.
