Walking Plates were prepared for fit check: welds were spot-treated with pickling solution, ink/stamps were removed, and then the sections were pressure washed. Bubba and I went down to Y-end and oriented cleanrooms preliminary to locating the mechanical test stand. Doug visited Y-end later and was satisfied with the location of the test stand cleanroom. Cryo-Baffle parts were uncrated and moved under the cleanroom at H1 PSL bay. Apollo started the process of dismantling and removing the BSC cleanroom skeleton from Y-mid. It will be transported to the LVEA and placed over BSC-4 so we can continue the fit check of Work Platforms and Walking Plates (which requires the dome off) with all the major components in place.
