Based on my review of the Mesa sapphire plant building permits it seems likely the sapphire manufacturing plant is active within modules 1 through module 4. Tool platforms (platforms that hold ASF sapphire growth furnaces) have been installed within the first 4 modules and each of first 4 modules (areas) appear to have been equipped with fire alarms and FS/TS monitoring at each Tool platform. I’m taking an educated guess that FS/TS is referencing flat screen (FS) and touch screen (TS) monitors on each Tool platforms, which would seem to make a lot of sense. Module 1 and Module 2 are known to be 12,500 square feet, Module 3 square footage is unavailable and Module 4 measures 162,483 square feet, which is large enough to hold well over 1,500 ASF growth furnaces.

The most recent building permit issued on 4/17/14 indicates that a request to work on the “central utility plant” to work on heat exchangers, cooling towers and installation of additional fan coil units. The images below that were taken on 4/10/14 indicate the exterior construction on the cooling towers and electrical station appear complete.
The 4/17/14 building permit description indicates that Apple is requesting additional work inside the uninterruptible power systems (UPS) and battery rooms (yes plural). For any of us who have not been inside a battery, this room within a manufacturing plant houses battery backup for uninterruptible power systems (UPS) and is critical to provide power if any outages were to occur. If Mesa loses power the UPS would kick in and deliver the necessary power to the ASF sapphire growth furnaces. Also, an additional request was also made to add exhaust fans with spark proof motors and H2 sensors in the battery rooms.

Fabrication Area with Centrifuge Platforms
Another interesting item is the fact that the Mesa facility includes a fabrication area that has been outfitted with centrifuge platforms. Centrifuges are usually used to separate liquids but other forms of centrifuges include analytical centrifuges, which can study just about anything including proteins and sediment.
ADDENDA TO BLD2013-05895, A04D DRB018, FABRICATION AREA BASE BUILD. INCLUDES CONSTRUCTION OF CENTRIFUGE PLATFORMS AND BUILD OUT OF FABRICATION OFFICE AND CONFERENCE, COPY, AND BREAK ROOMS.

Product Recycle Room 4,752 square feet
The Mesa facility is equipped with a 4,752 square foot product recycle room. A permit was issued on 3/4/14 to install a Pneu-Lectric double interlocked preaction system (these are fancy words for a very expensive integrated alarm/sprinkler system). If you are bored you can read about an existing Pneu-Lectric model here.
