Land clearing begins on the eastern half of the site, for Buildings 1-2

Building 2 foundation work begins. Building 1 generators seem complete, cooling towers still under construction.

Building 1 operational. No visible construction and roads/parking complete around the building. Building 2 chillers are beginning construction. Foundation work begins for Building 3.

Building 2 operational. Parking complete, no more visible construction.

Building 3 operational. Surrounding roads finished, no more visible construction.

Buildings 1-3 are visibly operational, with steam coming out of the cooling towers. Meanwhile Building 4 is extremely close to completion, with all backup generators complete with only 3 cooling towers missing their fans. ~1/2 the generators are installed for Building 5, and the roof is mostly complete (starting to install the final white layer, with the actual roof structure already complete).

Building 4 operational. No more visible construction, and since only 3 fans needed to be installed since Feburary, operational date was likely soon after. Building 5 roof almost complete.

Confirmation that Building 4 is complete. Building 5 has progressed since February, with a complete roof, all backup generators in place, and five cooling towers in place.
