EVERYONE needs a full set of drill bits.


Making sure it goes into the liner ?


No basement - this always strikes me as wrong - but this close to the lake makes sense.

Open question: Who is the GC for these towers?

I think up until now - someone please correct me if I’m wrong here - McHugh has been the GC for every single LSE building. But now, Magellan is partnering with Lendlease, which of course has its own GC arm. Just curious how this played out....did Lendlease (and Magellan) give Lendlease the GC contract here?

Lendlease is the GC and developer along with Magellan.

McHugh did most of LSE. Power did GEMS I and the currently stalled GEMS II.

I didn't know that was stalled again!

After it had a 2-3 week stall last year, I caught one of the project managers at subway (ha) and asked him about it. He told me straight up GEMS wasn't paying up.

Assuming same situation this time, GEMS is stretching themselves thin.

Makes sense, and completely forgot GEMS went to Power.

Appropriately, this is a mud wasp. They are generally harmless and collect mud to make tube shaped nests. Not surprising to see one by a site where they are drilling and making big piles of mud all over the place.

So she's no nightmare, she's a fellow builder to be celebrated. Just picking up some materials to build its nest:

wiki

They eat primarily spiders, so this is prime mud wasp season. Being downtown where the balcony spiders are in full bloom with a fresh supply of mud, this wasp is in heaven.

Also, this I never knew, but apparently mud wasps have been involved in a number of airplane crashes since they like to nest in the round holes of aircraft instrumentation. They will crawl into valves and airspeed sensors, build a nest, and the plane crashes. So you are probably less likely to get stung by one than to be killed by one in a plane crash...

When they started out their tuition was very high...higher than Latin, Parker, or Lab which are probably the top three private schools and their direct competitors. In five years the tuition has dropped substantially (from $37000 or so for a grade schooler to $31000) which tells me they're having trouble filling classes (which isn't an issue at virtually every other private school). In fact they are still advertising discounts for people that commit to the (non-existent) high school which seems ludicrous given how work has stopped.

Thank you ! I always enjoy the animals we share this land with.

For what it's worth, I spoke with someone directly at Lend Lease over the weekend who indicated that they're moving forward with construction of both towers at the same time. . . they expect foundation work to wrap up by the end of the month and they're expecting completion sometime in 2021. . .

Both towers got permits for cranes. So maybe you'll see 2 more cranes in Chicago soon..

The white stuff is Geo-Cloth - clay embedded to stop leakage.

So are the heights of both these tower going up reflected on whats shown on the title of this page or have they been shortened?...I didnt think either one was gonna break 500ft?

Steely Dan Oct 11, 2019 1:49 PM

the building heights we have listed in the title of this thread are from this post below on aug. 14th made by a known insider who has obviously seen dimensioned bid/construction drawings.

There are a few different ways that different cranes do it.. basically a badass crazy powerful hydraulic system pushes the entire thing up

Are all heights measured this way? From the lowest basement to the top? I had always thought they were from some sort of street level.

They actually use cranes to literally raise the roof...

Neuman Oct 13, 2019 6:18 AM

I have an infrastructure question, if anyone is able to answer. Since LSE is completely new infrastructure for the city, when they are building all the new sewer systems, are the sewers in the area shared for rain runoff and general waste water from the buildings? Since this entire site is next to the river and the lake do they divert rain runoff into those bodies of water, or is it all mixed in with the sewage? This would seem like an ideal place to start separating these systems, whereas the rest of the city is mixed sewage. I don't think the boards here discuss this type of infrastructure enough, and it seem fairly important on all these LSE projects, or any of these recently proposed mega developments Chicago is seeing.

LouisVanDerWright Oct 13, 2019 2:08 PM

I doubt the runoff for the entire complex is handled together. The city makes each building separate the run off and retain it. So every time another one is added to LSE the civil engineer will design retention to meet code for that project as they would with any other project.

I could be remembering wrong but I though LSE had a separate storm system they hook new buildings into and an outfall into the river for the whole development.

I imagine the streets just dump into the river. Interesting. I would assume they still require some form of retention though, they probably don't want everything just dumping into the river during a storm event either.
