COMMENT ON PACS Panel Upgrades (B23 Experimental Staging-B36 General Purpose -B97 Count House-B202 Hall D)

19 hours 50 minutes ago
Log Number: 4486935Logbook(s): Body: 

B23 work started today. It appears that we will be done today. We will start B36 tomorrow. There are a bunch of crates and equipment stored in front of the panel. Can we get that moved back enough so the crew can remove and install the panel? If not, is it ok if I move the equipment? Picture of the material is attached.
