More not nothing.

Skid steer and mini track hoe have been tearing up parts of the sidewalk, this has to be a sign.

Work begins 4/20, light one up for this one 😆

Is this still getting incentives from the Downtown Living Initiative (or whatever it was called) despite taking so long to start construction? If I recall correctly, this is the second-to-last one to get underway that originally qualified for the incentives (the last being the high rise NE of MMP, though that could be way off).

Isn't there another Campos residential near Toyota center that is part of the DLI? Only one Campos has been built.

They had been given an extension, but it required a temporary certificate of occupancy to be issued by May 28, 2020.  So, they would apparently have needed another extension to still get those incentives.

Or build REALLY fast

Or possibly a HLSR event?

I walked by Block 98 this morning.  Not sure what was going on, but there was certainly activity with a few workers on-site.  Maybe we begin seeing more progress in the coming weeks and this is still on schedule for 4/20 start date?

Will be really interesting to see if this one still goes through.... fingers crossed.

I took a couple pictures but my disk is full and won't download to my computer. I talked with the guys who were repairing the tension cables on the parking garage. I asked them if they knew about the apartments to be built but they didn't have a clue. To me it appeared they were tensioning the cables and then putting new cement over the ends.

[hindesky]

Threw away a bunch of old pics to make room. Time to buy a new computer for more storage for of all my pics.

 

Those guys in the lime shirts are the ones I talked to about what they were doing. I wonder if @Purdueenginerd knows what they might have been doing to the tension cables in the parking garage ? I also wonder if it might be because the work on the apartments is about to start.

@hindesky Those are post tension or prestress ports. 

 

There are three times of structural concrete construction

 

1. Traditional Reinforced concrete 

2. Post Tension Concrete

3. Pre-stress concrete

 

To understand the three, a brief cursory explainer on how structural concrete works. Concrete is very weak in tension, Great in compression! Lets talk about No. 1 first. In traditional concrete, lets imagine a simple concrete beam with no reinforcement (ie, rebar). Concrete, like every material on this planet, will bend. If you imagine a sagging beam, the bottom of the beam will be in tension, and the top of the beam will be in compression. With no rebar, the concrete will crack at the bottom and quick propagate upwards, splitting the beam in half and causing collapse. Ever see a martial artist break concrete block in half? This is exactly what is going on. Theyre impact is "flexing" the block, creating tension on the bottom face and subsequently breaking the block. In traditional reinforced concrete, rebar is added to the bottom of the beam to engage and resist those tensile forces. 

 

Above is the cross section of a typical reinforced concrete beam design. I wont go into the equations too much, but you'll see that the top of the beam is in compression, the bottom of the beam is in tension (as denoted by C and T, respectively). Now what are the limitations for this? In traditional concrete construction, the tension zone effectively always exists, this limits how long the span is. In addition the more load you have on it, the "deeper" the beam required to create a sufficiently large concrete compression zone.  For parking garages, is generally desirable to have long spans between columns because that means: more parking! 

 

So what is post tension? When the concrete is cast, they create this holes all the way through the beam/girder all the way to the other end. While the structure is shored, they'll run these high strength cables through the beam and tie them at both ends. The cables are then tightened, aka, tensioned, and locked in place. The tension in the cables in effect "compresses" the concrete. Remember concrete is great in compression. Post tension effectively put more of the concrete section into compression. Advantages include the ability to go longer spans with less depth. Disadvantages: less modifiable and more expensive to build-- Can also be dangerous if a cable fails. To answer your question, those holes are for post tension cables. 

 

Pre-stress is very similar in principle. You will most often see pre-stress concete in pre-cast garages. Prestress means that the cable was tensioned before the concrete was cast, then they poured the concrete and subsequently released the cables from tension, (which then applied a compression force on to the concrete. These are common at plant manufactured concrete shapes, that are trucked to the job site and put in place at the construction site.  The disadvantages are similar to post tension. 

As for why theyre working on an already existing garage: Not sure. unless it was to make repairs or modifications. associated with the builing that may go up next door.  This garage looks like a pre-stress/precast garage.

Work continues on the tension cables for the parking garage next door.

I walk by this garage almost every day and it looks like they are about wrapped up.  Fingers crossed we see this existing equipment moved off site in the next day or two and immediately replaced with new equipment.

It is moving along very quickly.  Expect groundbreaking soon.

Wow this would be really great. It will be wonderful to see downtown continue to grow despite the troubles.

Welcome to the forum, Paco. I will smoke a cigar if this breaks ground.

Literally right now is the perfect time to start a project. We haven't fully bottomed out, but with prices on everything being so low, plus interests next to zero, plus deflation, now is the time to dump money into something which will hold value longer than paper money. I say that because coming up next once the economy does start rolling is possible inflation or even hyper-inflation with all the money we are printing to get us out of this.

I agree - but if you're a developer, you need to trust that cycle. If you don't, you get bearish. Logic v instinct.

 

Looking forward to seeing shovels in the ground on this *fingers crossed* *knocking on wood*

Rendering from this past March.

 

[Geographer]

Wow, that's beautiful!

[TheSirDingle]

The garage section is so much better than the previous design, also that white stone paired with the glass is going to make it pop. Personally I think the white stone is a much better choice than the beige counterpart, and the design for the upper deck pool is also very interesting. Overall it's a step up from the previous rendering. 

[rechlin]

I really like how they changed the design of the parking garage, but with the skywalk to the Marriott Marquis now removed from the rendering, I guess this means there now definitely won't be a tunnel/skywalk connection between the convention center and the rest of downtown as I had hoped (and as the earlier renderings had indicated).  Too bad.

[jmitch94]

I like it! I wonder if that top part is one epic penthouse with a massive outdoor area or and amenities area like a pool. 

[cloud713]

The upper left side looks nice/like a Hanover product. The garage and right side kind of look like a cheap hotel to me though? 
Overall it’s a decent addition, but I wouldn’t be disappointed if this never gets built, preserving the Marriotts western skyline view.
A nice strip of retail, bars and restaurants, topped with some co-op/boutique office space that doesn’t go higher than the garage would be ideal IMO, or even some “more affordable” residential micro units, again topping out at the top of the garage. I may be in the minority though of wanting to preserve the Marriotts pool deck view.

The building is almost 85% composite metal panels.  There is stucco at the balcony return walls, but everything else is metal panels.  It does look good, though (imo).

It is a community pool/amenity deck with a cafe and separate connecting outdoor deck.  This is the best I could do for a visual.

 

Also, it does connect to the Hess garage.

 

[jmitch94]

Those metal panels will go well with the Marriott and the Hess tower. 

[CaptainJilliams]

Fingers crossed on this one, hope it happens.
