Comcast Center has 58 storeys? I'm not questioning you, but I thought it was 57.

But I could be wrong about that, although I don't understand why they'd isolate one tower from the other, when it appears that they'll join together to make an "L."

Perhaps GarCastle, who I believe works for Penn Medicine and has some inside info on this, will check in and provide some insight.

I believe they are going to interlock the lower floors. The upper floors between Smilow and the south tower will have some glass bridges. So they might all be connected, it's hard to tell by those illustration angles I posted awhile back - whether it will just be a narrow pass through or wider.

On a related note, Penn Med learned how to get back on the Top 10 in the Nation US News & World Report - by combining HUP and Presby somehow. So HUP-PPMC is #7 on the honor roll and the very first comment, within 5 hours of the posting, is some patient BASHING Presby LOL. Not about their doctor, or the care they got, but about the condition of the public bathroom. I forwarded it to marketing so we'll see what happens. Of all the things to complain about LOL, Go Philly! :^)

Looks like they've also combined Pennsylvania Hospital in there ("Hospitals [plural] of the University of Pennsylvania--Penn Presbyterian, Philadelphia"). I guess that's appropriate, given that all three hospitals are now part of the unified Penn Medicine. Glad to see the Penn hospitals getting the acclaim, commensurate with the perennial top ranking of the medical school.

Now, if they can just work on those public bathrooms.

They have started drilling

Yes! So are these where the support columns of the bldg go on top of?

That's ironic. I just got off the phone with my dentist office to make an appointment. The word "drilling" kind of hit a nerve! haha Glad to see them digging. Ouch, "digging" isn't too good either.

Thanks for the photo, Summer!

Where do you think they got those drill bits? [I'll give you a hint: they're from your dentist's office.]

They took this video the day that Wharton student was fatally struck on Walnut (ouch).

Hopefully the first caisson will be installed within the next coule of days. Then this thread can be moved to the U/C sub-forum.

Just walked by. They're installing the first caisson!!!! I have a picture I will post in which you can see the top of the rebar in the hole. Drilling rigs are drilling two more holes and they're prepping to drill a fourth.

This can officially be moved to under construction sub-forum!!!!

Can concrete trucks be far behind?

Installing caisson

Drilling...drilling.. .drilling!

I'm not that knowledgeable when it comes to actual construction, so can someone explain to me how this is going to work? Is caisson going to get filled in with concrete and act as a foundation? Or are they still going to dig the crater for the foundation and if so, why not do that first and then do the caisson?

From what I was reading caisson is usually used when there is water involved, for construction of bridges for example. I was under impression that for a building this size you would dig a giant crater, put support for the walls and fill it in with concrete for the foundation.

Thanks in advance for the explanation

I work on more of the business side of real estate so I'm not completely versed in highrise construction, but I think I know enough to explain. Anyone feel free to correct me where I am wrong.

Holes for caissons are dug down to the bedrock. The caisson is lowered in the hole and attached to the bedrock and then filled with concrete. Not all highrises require a hole to be dug. This really only occurs if there are subterranean levels or underground parking. However, even highrises that dig a hole for foundations will install caissons. It's basically what holds the building sturdy to the earth since the dirt directly under the building is less secure.

For FMC, there will not be any digging foundations like for CITC which will have subterranean levels and some underground parking. The base of FMC will already be lower than Walnut street level so caissons will be installed directly into the ground without any prior excavation.

^^^See 181 Fremont thread in UC forum for explanations, history, etc. caissons are to reach bedrock. Not familiar with Philly bedrock, but a similar sized building UC in SF has bedrock 260 ft below where the foundation will be poured. They drilled the caissons first and are now commencing excavation, an explanation for this order of events is also provided, though my understanding of FMC is that heavy excavation is not necessary as parking is in an existing above-ground structure.

Will be interesting watching this one rise! It will probably take 3-6 months to drill the caissons and fill them with concrete. It took about 6-8 months for both 181 Fremont and Salesforce Tower caissons in SF, but there are other complications here (super space constraints at 181, depth of shafts at both sites, seismic considerations, size of Salesforce Tower, etc).
