Got a bit more work done this week. Set three a/hs, finished the duct for units in mech room. Pics don't to that mass of duct justice, looks like its tied in a big knot! May try a shot from floor.
refer lines are all guy I work with, I did some tricky fitting together of duct meanwhile.
Stared this Thursday, 10ish today he finished the lines inside and came out to run some piping.
Knew this corner was going to give me trouble from day one
