Two weeks ago, a blue thing appeared.
In the last week of July, I got home from work and this blue thing, seen above, had appeared onsite. CF

If you're not familiar with Boring Report, um, not a lot happens. You can get caught up on Boring Report here.

Anyway, the blue thing. What is it? A slingshot? A crane?

Okay, maybe its not quite as eager as that trackhoe.*
Even by the light of day the next morning, I could not tell. CF

Whatever it is, it looked ready to work. Eager.

Big ups to the cement trucks.
Later on the scene: more things. CF

A day or two after the blue thing appeared, the white thing appeared. Pretty sure the white thing is the sibling or cousin of the blue thing although I'm no constructionologist.

Big ups to the cement trucks.

Look, some new machines.
Here they are on the opposite side of the site doing god knows what. CF

What you can't see well in this photo (at all) is that the blue thing is inserting a giant drill into the ground.

I realized that by standing and watching for a while. Even though the transit station is blocking a good view of the blue thing (as you can see), after standing and watching for a while I could decipher that it's a drill—just below the roofline of the light rail station, a gigantic drill bit turned as it churned down into the ground, then pulled up soil in a column, and then shook itself free of the fresh soil, and then, with a clean drill bit, dug into the earth again, and so on.

Presumably they're making room for columns for the foundation or poking holes in the Earth's crust so magma can spew out or something cool like that.

I still cant tell you what the white thing is.

Looks a little lazy if you ask me. Maybe I just caught it at the wrong time. Or maybe it's the thing that pumps the cement from the mixing trucks into the holes the blue thing makes.

Don't ask me! We report, you decide.

To answer the burning question I know is on your mind: How are the trackhoes doing?

The trackhoes are doing great.
