Spectacle Island and the Quincy Quarries both received dirt from the Big Dig. Dorchester was denied fill for an early version of Pope JP2 Park and to cap the illegal landfill that is now a park near the gas tank

Where do they go now though?

Depends on the quality of the soils.

For "clean" (contaminant free) soil, if you can't re-use on site, projects may work deals with other projects that need structural fill imported, so long as your soil meets their spec through testing. You can also send fill back to plants to process it into an engineered fill that meets various specs, and that plant will sell to projects that need fill. Even if a project (like this one) appears to be removing soil, they may still be importing some soil if the existing soils can't meet the structural requirements of the building.

For dirty soils, they're often sent to landfills - sometimes depending on the size of your cut, sending across multiple state lines is not out of the picture. There are some small local sites accepting fill. Here's one as an example, taking 200,000 cubic yards. If you're really stuck, you can remediate in place and either sell to plants or to other projects, but costs sending out to landfills are already sky-high, so in-situ remediation is an absolute last resort.

There's also facilities that incinerate the dirt to remove organic pollutants.

Going vertical:

About halfway up.

If only the ROW across Boston Ave could've been decked this would be a real corridor!

Also, this is an interesting construction sequence. Exterior insulation (and interior non-structural wall framing) is going up with each floor of steel? Typically all the structural steel goes up first then the other trades come in afterwards.

Yeah, I was noticing that too. It looks like they're using some kind of pre-fab exterior wall system. A lot of times for cases of steel-framed buildings that don't use an external facade curtainwall, we've seen manual installation of steel studs, sheathing, and insulation all around the building for these exterior walls.

I have a hunch for this case: since they have the three tower cranes going with full reach all around the building (which another poster above hypothesized was due to the lack of lay-down area on this site), they probably have the craning capacity and reach to be hoisting these pre-fab'd exterior walls into place in-process. That approach, in turn, might also be due to the lack of lay-down space for raw materials. Guessing that trucks show up just-in-time with these pre-fab'd walls.

Back when I was traveling this way more regularly I used to take pictures from the garage, but I always forgot to post them. Here's the last one from August 25, where you can see the site layout:

Yea I was going to say it appears to be some type of prefab exterior system being used with the insulation already installed. Pretty cool imo I dont remember seeing a system that looks exactly like this before. Seems like itd make construction much quicker.

I think the Prism residential building on Rogers St in Cambridge used a similar system.
