Year 2, Day 207: 24 May 2014

It was a peaceful Saturday at the substation, but here are a few pictures taken yesterday. The main work at this point seems to be digging out the sewer line.

something worth seeing.

Excavation for the sewer line, with trench boxes set up.

Working on the mysterious yellow boxes on the lower roof.
