For reference the tesla charge stations are directly above the entrance driveway from Valco Parkway. Equipment is slightly visible in full size photo.
I
The shorter I beams are for the big white circuit breaker panel, and the larger pair is for the charger cabinets. The charge pedestals are on site in boxes, along with the low voltage control cables on spools. Weight is of concern in a garage like this, thus the I beams to both spread load, and provide conduit space below.
Their biggest challenge is routing the 480 vac power cables up from the ground. They have chosen inside a stucco covered architectural column, and cut tiny holes inside, where a tech is rappelling down inside and hanging 100 pound rigid conduit segments. One conduit per phase, 3 phase 480 vac, plus the smaller ground conduit. This is genuinely hard work. (See yellow ropes leading down into the hole.)
Looks like they are busy out front siting the new 1.5 mW transformer conduits and possibly some power packs (too early to tell)
