More HVAC work. Ducting was extended to the LVEA wall and into the return air plenum - the contractors drilled a hole in the LVEA wall for this. They also began finshing work on the interior and exterior drywall, taping joints and patching over screws.
Dust counts were low for today. One spike to 5000 at the 2K PSL at 0.5 microns, but other than that it was below 3000 for the whole day.
