Can anyone here decipher from those diagrams why there's no elevator shaft visible in the current construction photos?  I assume it will go down the central part of the building per the last cutaway. 

[bnacincy]

I think one of y'all down there is just gonna have to go to the construction site and ask them about this.

Just hope the reply isn't "oops".

Ohmigosh! I thought the same thing... I had this apocalyptic survival horror movie in my head that consisted of a band of travelers that had to band together to combat the evil horde that awaited them in the pits of this crazy garage to be able to escape to freedom. (I've been binge-watching Prime Video too much.)

Here are a couple edge of slab plans from the pdf package. The dashed 'X' represents the opening in the floor. I couldn't see any openings from the images, so maybe they have the shafts blocked off until the next trade comes in to build them. If there wasn't the cast-in-place shaft like we are used to seeing, they are probably using shaft wall to enclose the openings.

Second floor:

It also continues on the upper floors, Floors 5-10: 

Edit:

If you look close enough, you can see something that appears to be opening in the slab where maybe some temporary stairs are in place....

It's great seeing the residential part of Broadwest rising above ground now. So... at 36 stories, is this the 2nd tallest under construction (by floor count) in Nashville?

Correct. The 4 Seasons followed by Broadwest.

Glass has started on the east side. I wasn't able to get a photo while driving.

I was curious when this was going to start. They’ve had the anchors on the concrete for a while.

But for real, where is the elevator shaft for the office tower? At this point, I'm almost suspecting an egregious engineering error.

There is an opening in the center of each floor that is difficult to see unless you look at just the right angle. I can see it when I drive by the site, but it would be hard to get a picture of it.

They're going to use a fireman's pole.  Coming down is easy.  Shimmying 22 floors up the pole will be a bit of a task, though. 

[Craiger]

You can see what looks like three floor openings when you drive by. Two seem to have stairs in them right now. Not sure if those are temporary or will be the final stairwells. The other shaft has several large pipes in it right now. I'm assuming some of that is for the concrete pump.

Really?

 

Unless the elevator shaft is a source of interior support for a building, they don't need to be solid concrete bunker-type structures. With all the concrete columns on each floor, the elevator shaft in this tower will likely just be surrounded by thick fireproof drywall or simple masonry.

The website says 10 high speed elevators and a freight elevator, so they know where they are going, even if we cant see where they are going.

Seems as if everyone thinks the a GC like Turner and Hoar woild make a mistake like that. I dont think so.

If you go on the web there is a big building in Spain where the architect actually forgot about the elevator.  Smeags is right.  Ain't gonna happen here.

Looks like the office tower cranes were raised today. 

[titanhog]

Maybe it will be like a secret room in a mansion where you pull a book on the bookcase and the elevators open up. #secretelevators 

[Salbato]

Screenshots from a video on Instagram broadwestnashville. They had multiple videos today on their Stories. You can see where the stairs and elevators will be located.

It’s a bit shocking how long this board has discussed whether a 22 floor building has elevator shafts.

Are you implying that an elevator would really take this project to another level?

OK, I've lurked enough on this fascinating string of posts about the "missing" Elevator shafts, so I will give an architectural  discourse on shaft construction methods.  I address methods which are suitable for the type of construction at Broadwest as poured concrete cores or masonry cores are typically constructed independently of the floor construction.  We see the slip form concrete core at the Amazon tower and the masonry cores typically on low to midrise structures as we see a lot on apartment buildings here in Nashville.  Specifically in the Broadwest office tower of which many of you are freaking over, Bos2Nash posted very clear floor plans which clearly show SEVEN major floor penetrations which will be protected with a 2 hour U.L. (or equivalent testing authority) fire rating.  There is no such thing as "thick fireproof drywall" per se.  "Drywall" is a Brand of gypsum wall board as is "Sheetrock"; both are misused and must be carefully  worded in specifications unless for some obscure reason you would call for a proprietary specification.  In the past these openings were almost universally enclosed with a shaftwall system which consisted of a base runner (J-runner profile), studs (CH-stud profile intermediates and an E-s tud at openings and ends of runs).  In the case of a mechanical shaft, the H part is to receive a 1" thick liner board so the "H" part is much less deep than the"C" profile.  The total depth of the studs vary with the height of the span of the wall, from 2.5" to 10" or more.  The I" liner is slipped into the frame created for it and Is NOT sealed, taped or otherwise fastened.  Then, on the occupied space face, for a 2 hour rating, two layers of 5/8" type X gypsum board (fire rated board) are attached with screws.  Lapping of the layers is assiduously called out  for lapping of joints and details for taping joints are  followed and a finish is applied over this.   INSIDE this shaft is this loosely applied liner board as scaffolding cannot or would not be used typically due to inaccessibility or costs.  This covers  simple mechanical shafts and elevator cores.  What about stairs?  Stairs typically have finished interiors, so the 2 layers of gypsum board can  face inside of the stair and a second ordinary stud wall (*which has no part in the fire rating and only goes to 4" above the finished ceiling plane) is used to protect the liner board.  Electric outlets and other recessed items go in this unrated wall.  There is an approved alternate for stairwells in which the liner board is to the inside of the stair and one of the two layers of 5/8" board covers it and only one layer is on the occupied space side.  Any penetrations (if allowed by code) from the occupied side must be "box" protected.    Whew.  This only covers the most basic applications.  One of the procedures that I have fought for is to abandon the automatic assumption that shaftwall systems such as these are best solutions.   Shaftwall systems are certainly more cost effective to use where the floor to floor height is between 10 to 12 feet as you can get the liner board in those lengths.  If the height is more, there it extra horizontal joint and heavier gauge or depth  studs adversely impacts the costs of this system.  As an architect designing hospitals, I regularly had 14+ floor to floors,  so I abandoned shaftwall systems in stairs and other instances, using shaftwall only where unavoidable.   I "value-engineered" a major hospital stair system and saved over $250,000 in the budget. Many architects fail to consider alternates to the shaftwall solution including it from habit.  Why did I challenge this practice?  A simple 2 hour rated wall system consisting of a normal wall stud  and 2 layers of type X board on both sides is hugely more cost effective than shaftwall.  Care of lapping joint placement is still a requirement, but the inside of the shaft or stairwells require finish surfaces, so abandoning the liner board and special stud profiles affords a great cost savings, especially when floor to floor heights grow.  Penetrations on the occupied side can be resolved with the same furred wall or boxed outlet solutions as with shaftwall.    In this specific design, the lower floor to floor height of office occupancies,  I would assume conventional shaftwall systems will be used as described above, though in the higher floor to floor spaces , more cost effective assemblies could be utilized.  I have no idea whether the contractors or the architects have considered possible savings as the automatic usage of shaftwall is so ingrained in the industry.  This post only covers some of the most basic variables.  In the Broadwest floor penetrations, there are 3 elevator cores 2 stairwells and 2 large mechanical shaft openings.  Please be aware that any plumbing risers will only be in the 2 mechanical floor openings. Codes do not allow plumbing in stairways or their walls.  Also the elevator openings are clearly for 3 elevators, so an additional fire rated wall must be provided on one of the 4" wide spreader beams for the elevators as the evevator codes only allow a maximum of 2 elevators in a rated shaft enclosure.  All those movie elevator scenes like in "Diehard" are pure bullcrap.  The duct openings at each floor and all the light fixtures are Hollywood bogus carp.  Likewise the open unenclosed elevators in "Mr. & Mrs. Smith" are ridiculously staged too.    I hope this short course in shaftwall uses has enlightened those of you not in the building trades.
