West door was removed from BSC 9 and broke bolts on west door of BSC 3 in preperation for that door removal. At E Y we completed assembly of the work platform around BSC 6 and moved the clean room over same. We began moving test stand clean rooms and work station clean rooms into position. I took some measurments for the test stand/e module interference at BSC 10 and it appears we will NOT have to redrill for the test stand, however it does appear that we will need to place a second sprial stairway (from E X) in position before the e module move.
