They pretty much stopped glass installation several months ago. Did they hire a different company to do the new windows?

"It has already been 9 months... and counting. The window contractor should have 9 months more of work complete on the project as of today. "

Was the second crane that has already come and gone going to assist with the glass install / hoisting, I wonder? For the last 9 months I imagine it could have been put to good use. Hopefully, not having it doesn't make the anticipated installation time longer still than what was estimated. Silver lining, I suppose is that this thing looks so cool without the glass too.

It's window wall so they install from the inside without the help of a big crane. Cranes are used for curtain walls

IIRC, I've mentioned this many times, it's not just a problem associated with the balcony doors... and the 'other' window wall, the one associated with the '2nd vocabulary' on the cantilevered box, for example, has failed too (without any balcony doors involved)...

Oh ok thanks for the clarification. Part of the major problem is McHugh decided to let the glass manufacturer manage the installation rather than a more reputable glass project management company, i.e. Enclos, Harmon, etc.

Very bad news...today's mock up test failed. Look for more delays on the glass

Oh man, that is bad news... this is costing someone a fortune.

I'm sure the per diems have already kicked in for the glass manufacturer/installer. McHugh better be getting worried about per diems kicking in for this entire building at the end of the project. At what point do you just shit can the entire glass sub and start over???

Amazing. Delays when I do construction at my extremely microscopic level are.....a costly and annoying inconvenience. I can only imagine what the Vista developers are going through.

The problem is, they probably already have money into the glass sub....so unless you want to delay the project further with costly lawsuits, your best bet is to suck it up, come to an agreement, and keep things moving.

One way to get back at the sub is to screw them with their final payment. Of course, you can get away with that with tiny projects but at this scale you’re talking about liens and lawyers, big time.

Ah, i was wondering why there wasn't any litigation...

Skyguy_7 · #**4033** Posted **Jul 27, 2018, 2:51 PM**

^^Yep, best option is to suck it up and come to an agreement. It takes a team to build a building. Does no good when the quarterback works against the rest of the team.

I honestly can't imagine how the they've designed the mullion/window-wall construction of the cantilevered portions of the frustums; where each window hangs over/out from the floor below it. Does anyone have access to the detail on the plans?

I can think of a similar scenario at Roosevelt University tower, but that's curtain-wall I believe. Are there any other similar examples?

Nearly certain that Vista will have a window-wall, not a curtain wall. From looking at renderings, it appears the window frames will be inset very slightly from the edge of floor plates. The concrete floor plates between look to be capped in metal panel (they might just be left as bare concrete, but after the thermal-bridging issues with Aqua I'm not sure if Studio Gang would do that.)

See this link for a close-up rendering of the facade

I believe originally the glass was angled to overlap the floor plate below (See here.) but that appears to have been designed out. Now the glass panels will be vertical.

pilsenarch · #**4035** Posted **Jul 27, 2018, 5:26 PM**

I believe I mentioned a while ago that I heard that they were developing new dies to manufacture completely new profiles for the glass framing... guess the new ones failed as well... bad news indeed...

PittsburghPA · #**4036** Posted **Jul 27, 2018, 5:38 PM**

Just heard there is no way they'll start from scratch. They will have to suck it up and keep the course with the current manufacturer. Let's hope they can get it right. At least it looks like the concrete team is kicking butt so I'm sure once the mock up gets the green light it'll be off to the races. I'm staying optimistic!
