They do look like condensers, hard to tell for sure. In one of the pictures you can see on the left side of the building (through the fencing) what looks like the existing condensers. Two of them.
This has been a nagging question of mine at site #1. In those pictures I'm looking for two things that I haven't found yet. The outdoor HVAC units, which should include a fresh air exchange system, and any improvements to electrical system.
I know beggars can't be choosers, but to those taking the pictures, can you please include the company vehicles of those working on site? Those of us in the building trade can tell a lot from what type of trade is working on site.
