I imagine they'll just hold off putting logos on the building until the refresh is official.

In Japan, they often start going upwards at the same time as they are excavating. I watched as Toranomon Hills Business Tower was being built and they were installing windows on the 35th floor while dump trucks were coming out of the parking garage loaded with dirt.

Sounds crazy to go up before finishing the bottom in a country that's prone to earthquakes

They drive giant steel beams down into the ground (to bedrock?) and then attach the building’s steel frame to these anchor beams. As they excavate the basement floors, they install braces between the beams. The parking garage ramps and the subfloor are all metal welded to the braces. The excavator and dump trucks all stay on the metal ramps as they snake their way down. Other bonuses: allows for smaller dump trucks so no giant trucks on city streets and from the start of construction, no vehicle tire touches dirt.
For earthquakes, I think most of the dampening features are at the top so I worry about any tall building before it’s completed.

Dampers can be and are installed during construction, although that's for bridges, but I'm sure it can also be done for buildings.

It IS done for buildings. Regularly. Even here.

Mass tuned dampers are included in pretty much any building over a certain height. They are not used just for earthquakes but also to reduce wind sway and mitigate resonance events in skyscrapers which can be incredibly dangerous.

Yes, I know what a TMD does. My point is that it can be installed *during* construction to mitigate construction specific vibration and wind issues.

Out of curiosity, what purpose did these I-beams/pillars serve? Were they just to support the weight of the buses in the old terminal?

This has to be one of the most photogenic buildings in the city.

Wow, does this tower ever make its neighbours look even more execrable by comparison. Pinnacle should be hanging its head in eternal shame for its quartet of uglies.
On another note: it's astonishing how fast the excavation is proceeding for Tower 2; at this torrid pace it might actually be finished before The One.

I'm not certain that a 'torrid' pace is required to get completion faster than 'The One'.
