Corner Station update -> I'm done inspecting the Corner Station and am off to do the other buildings. Note that I had to add 850 ml of water to the TCSY chiller. I walked the entire run of piping from the chiller to the table and found no evidence of a leak. Additionally, there is no evidedence of water spilling of off the table (did not open doors). For now, I've notified Dan Brown. He said that he checked the table earlier today but found no leaks. I suggested that he check the table again and also the TCSX table in case the chillers have been switched or mislabeled.

Finished with the site inspection. Here are the highlights:
1) Had to add 850 ml of water to the TCSY chiller to bring it up from the, as found, 7.6 cm to 10.0 cm indication.
2) HAM7 AIP is off scale high -> we will deal with this after the new year.
3) Double doors (to HVAC computer room) between the auditorium and rear entrance of the LSB won't close completely and had to be blocked closed.
4) The exterior-most doors of the LSB main entrance were found to be locked -> At one time, these were going to be left unlocked and the interior main entrance doors were going to be locked instead so that people could get in from out of the cold? -> I left these as found.
5) Could not enter into the LDAS area adjacent to the VPW -> won't take my key or RFID "thingy".
6) Warehouse (dirty side) was unlocked -> I locked it.
7) Y-end chiller bypass valves (both) are open. The CS chillers are bypassed as well but all of the other out buildings have at least one of two valves closed -> I left as found as I am out-of-date as to what is normal these days.
8) Chilled water pressures are below the old nominal value of 30 psig in most buildings but I did not add glycol solution as this could be the result of the "new-since-my-era" Variable Speed drive units running below 60 Hz and I am likely out-of-date as to what is normal these days.
9) I could not investigate the X2-8 gauge/charger/etc. as they have changed the ocks on the BT doors and the gate code didn't work to unlock them -> I trended this gauge and it is on again, off again over the past day or so. I noted that the solar panels are "squeeky" clean and not obstructed.

I checked TCS X and Y tables and couldn't see any water on the table.
