General Information

Start: 5/1993
End: 8/1993
Person days:
Comments: No backfill documentation available. There are "Backfill Reports", but these reports are basically just the photographs put on a sheet of paper with no backfill information. Some "After backfill" photos were originally entered into database as a 1996 project, but the photos are part of the 1993 backfill project. The 1996 "after backfill" photos were merged into the BC 50 1993 preservation records. Note: Some of the drainage pipes were probably removed sometime before 1998 in some rooms. We know this because the crew did not find any pipes or drainages in the rooms.
