I see they've specifically noted the pyro parking lot back on Maple, near the fireworks sheds. And on the first sketch, they've simply outlined the entire NSA. Without knowing what SAMS is, the fact that they just say ELECTRICAL leads me to believe they're really just doing electrical infrastructure work.
The "DISC" building stands for Disconnect - which is essentially a large electrical switch that throws high voltage service on and off. They have Disconnect Rooms all over property, which allow them to kill or re-route power over their grid.
It would absolutely floor me if they do NOT use this technology to produce near perfect wait times. Given that thye've just launched an app with one of its primary features being Wait Times....and the fact that once every guest has an RFID chip on their person....it's a no brainer that they will eventually do this. Most of the logic has already been figured, since each ride's operating system knows the capacity of the ride in terms of guests/hour. They simply count people who enter the queue, count them as they enter load, and always know how many people are in line. Combine that with the current ride capacity, and it can change the ACTUAL wait time.
It could just be as simple as tracking one person as they enter and exit the queue, but that's what they do with the red cards. By counting the actual people in queue, and factoring how quickly that queue should flow onto and through the ride, a few calculations by a server and the Wait Time can be accurate to within minutes.
Soooooooooo much potential with this technology. Far reaching beyond just tracking what we buy. It really could improve the guest experience.
