Evidence of plumbing rough-in. This is where the bathrooms will be, with the white pipe in the centre of the building just on the outside of the men's bathroom wall (we think it is a cleanout/access point or perhaps a floor drain - it isn't on the plans, but it is right above where we tie in to city sewer.

The 'h' in the background is where the dividing wall between the men's and women's bathroom is. And just out of picture on the left, almost in line with the white pipe, will be a drain for the sink in the concession area.
