Yesterday, the north door and the dome were removed and soft covers installed. The regular soft roof was replaced with the SEI soft roof. Once those activities were complete, I entered the chamber to document conditions prior to any installation work beginning. (The last activity in this chamber was ICC.)The chamber walls showed little re-oxidation but the rim and the floor showed some re-oxidation and a few small, shiny bits. Please see pix attached. Then, the Apollo crew installed the walking plates and I did another inspection to see whether that activity generated any noticeable particulate in the lower chamber. Things did not look any worse after the walking plate installation.The BSC flooring was installed but without hardware since the hardware kit was incomplete.

The Apollo crew started installing feedthroughs this morning. They also continued with a few staging activities like stocking the in-chamber carts.

I re-arranged things slightly to mitigate the crowding issue in the lower level garbing cleanroom.
-I moved the shoe covers out into the buffer cleanroom so please make use of the bench and don shoe covers there. There is enough room for dedicated cleanroom shoes there as well. It makes sense to leave your personal items (Coats, jackets, beanies, stocking caps, etc.) on the shelving unit.
-I sorted through all the garb that was sitting around in bags and totes. All used items went into the laundry. The clean stuff went into the totes of back-up garb which are on the shelving unit in the change room. I will try to get those labeled today. There is some open space on that shelving units for personal items or stuff that you may need but don't have room for in the VEA.
-I rolled a shelving unit into the VEA to provide some off-the-floor storage space just outside the lower level staging cleanroom. There is still quite a bit of space open so please do not "store" things on the floor.
Please continue to bring your garb kits with you when you work at Y-end.
