I wanted to check back on this document but it's taking me to the main page. Does the document still exist?

The City redesigned the Historical Commission's website several months ago and as a consequence many files vanished and/or old links broke. Here are the minutes from that meeting, if that helps: https://www.phila.gov/media/20190327...s-20180413.pdf

Anyone remember that crappy render I made of The Laurel from the same view? Here it is redrawn and more accurate

Sorry for size

At least it’s moving at all.

Different problems, but the W site took forever to dig their hole. I wonder if they will have to do similar underpinning on the east side as well. This work had to be expected, so we might not like the slowness but I'd bet its not a surprise for the building team. Nothing about getting something built here has been fast; everything from the day the theater burnt down has been glacial, including since Southern bought the site.

Honestly, I think it's moving at a reasonably pace, now that it's started. It's a complicated & constrained site, surrounded by historic buildings. It's going to take time.

Major problem with the W seemed to be all the unexpected trash they found when they were digging (railroad equipment etc.,). I can only imagine what sort of headaches that created from a safety and disposal viewpoint. Luckily they don't seem to have hit anything like that here.

Excavation is a dangerous business, if your sloppy bad things can happen very quickly.

Looks like they pouring cassons on the east side today!

Certainly a lot of equipment packed in there.

Caisson installation! That means this is under construction officially!

I remember I was so struck by pictures from the early excavations of the W of the amount of red brick so far down. It looked as if the they had to dig through dozens of feet of red brick remains from prior times. I'm sure it couldn't have actually been that much, but there were pics showing broken red brick way down in that pit. Which makes me think the modern city sits on top of the ruins of the older city. And this mention of buried railway debris kind of confirms that.

I don't recall railway debris, but the parking lot on the W site had substantial portions of the foundations of prior buildings buried underneath.

Search for all posts by username blenfest to get a good idea of what all they encountered down there.

From yesterday. Looks like the first of the caissons being worked on. Hard to get shots through the chain-linked fence but you can still make out what's going on.

Thanks for the shots. Helps give the depth to things that is hard to guage from the contruction webcam. Also shows how tight this site is.
In particular the last shot shows how far down they are going to underpin the house to the west. Slow and delicate work here.

Minor nit with your terminology. Unless I'm missing something, I don't think caisson is the correct term. Probably a pier foundation here.

They are indeed called caissons:
