Marriott Marquis - New GRB Convention Center Hotel + Retail


Recommended Posts

From 59, by Minute Maid Park, this thing and the Hampton Inn/Homewood Suites already look HUGE. The Marriott Marquis is about as tall as the GRB, and the HI/HS covers a lot of ground, so downtown finally looks like one continuous mass of buildings from 45 to 59! These are exciting times!

Agreed!

Add the additional new buildings planned for the area and it will really look amazing!

The advantage of being at work early....

question for construction gurus...

 

Do they typically raise cranes (increase how tall they are) during the construction process? Or do they usually build them from the get go the size they need.

 

Thanks in advance.

I think we have a crane operator who posts on this board--- he(or she) can probably speak from experience. But from an engineering point of view, think of it this way, If i'm building a 600 foot skyscaper, and I build the crane to 600 ft tall before any building is up, then I have to account for the wind loads of all 600 ft without any lateral stability. We all know that Torque is a function of Distance times force. Another word for torque in structural design is Moment. A 600 foot tall crane, is going to have an enormous moment at the bottom which will require a larger crane foundation(not to mention soil restrictions may control the design). So, basically If I'm restricted in real estate like many projects in downtown, a shorter crane is easier to design for at the beginning, As the building goes up, I can extend the height of my crane, and anchor to the structure for lateral stability (which is, designed for those kind of wind loads). 

 

 

Check out this corny video on how these things are assembled

 

 

Mute if you hate montage music.

Interesting to note that on the Crawford street side, the structural columns that are just now rising to street level are steel instead of reinforced concrete used in the building structure that is rising closer to GRB.

I saw that too.

Parking structure and pool and likely a floor of conference facilities will be in that box, right?

I didn't think there is any parking structure within the hotel building, but looking at Morris Architects description it appears there is an 8-level 750 space parking garage.  (I thought the hotel's parking was all going to be in the building being built across Avenida de las Americas.)

 

In addition to apparently including parking, the box will contain the pool and three floors of conference facilities, etc on top of a floor of lobby/restaurants etc.

they will start at the minimum height, then jack up the crane as the building increases in height, if necessary.

It all depends on the final height of the building.

Short buildings, they will usually not need to increase the height much, supertalls they may jack them up a few times.

I'm loving the impact this building is already having on the area. Love the slick look of the final renderings.

I wonder if there is room on site fir expansion if the convention district demands it.

I think this will be the US MM with the least number of rooms but with one of the best looks. I do like the SF one too.

The ATL one has the most floors but looks outdated. The NY marquis is the tallest and has the most rooms, but I like the renderings of ours better. The DC one is the shortest at only 18 floors, but still has more rooms.

With everything going up on the east side of downtown I am hoping the convention district takes off and expands even more.I loved staying att the Hilton because of the atmosphere around discovery green, can't wait to stay at the MM

I was wondering how they formed the slanted columns. Very nice. They have a rectinlinear formwork, just like a typical column. Then the 4th side (the slanted side) they offset inwards (see the 2nd picture). Probably a through pin/pipe to set the angle. 

 

 

Thanks for the pictures!

 

They would use the same formwork, but it would have additional bracing to get the angle for the slant. As far as maybe using different rebar or a particular type of concrete I do not know. I'm still learning about stuff like this. Would be better to ask a structural engineer :P

From the webcam, it looks like the blue crane segments went into the taller tower crane and it also looks like they are assembling another red crawler crane.

if my cellphone camera wasnt so grainy you could more easily spot the 8-9 active construction sites in this shot..

construction sites from left to right

Nau Center

GHP Building

GRB CC renovations

Marriott Marquis

Hampton Inn/Homewood Suites

Texaco Building renovations

609 Main

Market Square Tower

and something happening up around the Westin sign.

i bet someone could get a ridiculous panorama from the Hess garage roof, including a few more construction sites that i was unable to get from this angle.

So the lower body portion is going to be steel construction? Interesting...

 

That might have somehing to do with the particulars around the pool deck and whatever equipment they need to run the pumps, etc. That thing is not going to be a simple undertaking.

yeahhhhh I distinctly remember my Structures professor warning us to avoid putting any significant bodies of water on top of our buildings specifically because it's a nightmare to figure out in regards to loads, and protection of the structure from possible leaks because once you have a leak in that pool...dum dum dummmmmm

yeah, bodies of water on top of a structures arent fun. Big inertia problem during earthquake and wind loads. An Olympic swimming pool has about 88,000 cubic feet of water, which is about 5,600,000 lbs of just water over an area of 164 ft x 82 ft. That gets you a load of about 414 psf. Which is basically, 'really freaking heavy'. I briefly looked through some of the codes for loading regarding swimming pools. Couldnt find it (at least in the 5 minutes I looked) but I did find ice rinks are specified at 300 psf. I'd imagine theyre dealing with similar loads. 

 

That being said, I'm not sure I would conclude they've elected to go with steel framing at lower elevations due to the presence of the pool. Generally, I would expect the 'higher' load areas to use reinforced concrete. I guess if we see a hefty lateral bracing system, it could provide more evidence that the pool influenced the steel framing design. 

 

/speculating.

Not just the structure, but the program and organization of the entire building as well.....ok maybe not complete reorganization of program. I assume that if the architect and engineer BOTH said the lazy texas river was ok to put on a roof then the architect and the team of designers must have done a fantastic job early on programming the building and making earlier design decisions which could then make it work for the client. It's obvious that the water will not be over any areas where people will be sleeping or living. I wouldn't be surprised if this pool is over a large assembly space so if there ever was a leak it wouldn't be hidden in a forest of walls. I'm actually curious as to how they handled this design problem both structurally and aesthetically.

Speaking of hotel pools, the Hyatt has one above their garage and you can hear/feel a strange echo every time you walked on the bottom. Their pool, is of course, nothing compared to the size and scope of this.

 

I'm pretty excited to see the finished project. I think I will be visiting this pool.
