Construction Paused At Miami’s Deepest-Ever Parking Garage, Being Built Under 47-Story Una

The city of Miami will order a temporary stop to construction at the Una Residences site where Miami’s deepest ever parking garage is being built, according to Local 10.

Groundwater has flooded the garage construction site multiple times recently during King Tide season, causing concern from neighbors.

According to emails sent late last month from Miami-Dade Department of Environmental Resources Management Director Lee Hefty, the situation is not an environmental concern, and mainly just a disruption to construction caused by groundwater.

The contractor for the project has also said that the flooding was not a breach of the aquifer which provides drinking water for the area, according to a neighbor.

Nevertheless, the city wants the site to be inspected by a geotechnical engineer, a structural engineer, and a seismic testing engineer before allowing construction to resume.

Residents at a neighboring property claim that they have seen the ground moving and sinking, Local 10 reported.

Developer OKO Group began construction on the project in 2020, saying it was the deepest and most expensive parking garage ever built.

Construction of the garage alone was expected to take a year and a half before the rest of the luxury Una condo tower could go vertical, at a cost of $25 million.

In November 2020, the developer had said they expected to begin vertical construction on the tower at the ground level in late 2021, after building three underground parking levels.

The main benefit to the extra time and money spent build underground is better aesthetics, with no ugly parking garage above ground.

 

Update:

A statement provided by William J Real of Civic Construction Company, Inc., Una’s contractor:

“As is the case with any high-rise development in South Florida, our team has experienced a series of minor leaks during the excavation process at the UNA Residences construction site. The source of these leaks is the water table, which does not interact with Biscayne Bay or drinking water. Because the water table spans across South Florida, water intrusion of this nature is common during the early stages of high-rise developments in the region. Our team is remediating these leaks as they happen, and there is no evidence of impacts on surrounding properties. We anticipate that additional leaks may occur as construction moves forward.”

Now we know why developers don’t build underground garages in Miami.

“NOW” we know? Why did we not know that before? Does anybody here have a basement? Has anyone EVER dug a parking garage in South Florida like this before? NO, because the water table is too high!

But, enough money changed hands for a permit to be issued for this absurd project, and there you go. Enjoy the property subsidence, neighbors!

No, you’re clueless. You are commenting on an article about complications of an underground dig that have halted construction, and your comment is that underground digs are no problem. The whole article must be a misprint. Brilliant.

Wrong.
Wrong.
Wrong.
But dont let that stop you from posting…

Burdines/Macy’s at Flagler & Miami Ave has a basement, Brickell CitiCenter, Capri Southbeach, the old JW Marriott at 3rd &Ocean Drive, 87 Park, Jade Signature in Sinny Isles, etc. All have underground parking. There are plenty of others I’m sure.

What is different with this one is dipshit Politicians, and the useful idiots at Channel 10 who are seizing on this.

Note: The article quotes a construction expert and the head of DERM. Construction guy says it happens all the time, no environmental exposure to the bay, and no damage to the aquifer.
DERM Director says no environmental exposure to the bay, and no damage to the aquifer.

Politician Ken Russell says, “The aquifer breach has been capped”
He is lying.
It’s a lie.
The aquifer was not breached and he knows it.
He is lying.
The truth is irrelevant to liars who raise money on their “climate advocacy”.
Easiest racket in town, if you can live with yourself.

Downtown Dadeland is another big and modern development with an underground garage of one or two levels spanning many blocks

They DO build underground garages.
The reason they dont do it more often is that is is expensive.

Realtalk Reilly

Yes, that is called being PROHIBITIVELY EXPENSIVE. It means when something costs so much that the utility of it does not warrant the expense.

The reason is it so expensive is because THE WATER TABLE IS TOO HIGH to feasibly dig underground without tremendous ONGOING maintenance expense for the life of the structure. The Port of Miami can afford it. A condominium cannot, not even one occupied exclusively by millionaires.

Yes, they keep the port tunnel dry. It costs $33 million a year to do it. These condo owners THINK they’re rich but we will see how they like ponying up 8-figure annual maintenance fees to keep the water out of their basement.

TNM should start making people choose a name to post comments under.

Any time there’s an article commenting on a deficiency or anything that is in any way negative or critical of a project, the developer tells its employees to flood the comments section with bullsh*t rebuttals of the criticism. Sometimes you can tell it’s just one or two people, but they go up and down the page commenting to make it look like it’s a consensus opinion. Sad! 🙁

Okay… should I choose a name like “Realtalk Reynolds” so that people will believe that I’m an authority on the topics where I post?

(See list of condos with underground parking listed above. The list is not exhaustive, but it’s enough to prove the point).

This was literally the worst idea they’ve ever had. I can only imagine whoever the architect was is some lunatic “visionary” who wanted to “exceed the boundaries of possibility”.

Yeah, a true “visionary” architect like Arquitectonica or Kobi Karp would have a glass box and ten-floor parking garage spanning the entire block, but don’t worry, they would cover it with some “art” in public places.

It’s not impossible to build, all they would need to do is build the underground parking like a swimming pool using gunite. Of course they would need to make sure the pumps are running non stop to keep out the ground water until the concrete sets. It would also need a few hydrostatic pressure drain plugs that stay open always, and immediately after the concrete sets they would need to flood the basement until the building is topped out (assuming the garage is centered below the main tower) and then once topped out would need to be pumped constantly or could possibly be capped. If they don’t have the drain or if the drains ever get plugged and the concrete sets they will basically have a boat and If the pumps stop running That cement shell will lift out of the ground……actually float out of the ground.

I don’t understand how there’s a groundwater fear when we get our water out west. Either way basements are just cool.

The soil in miami is limestone (I think) but whatever it is it’s very porous so there’s pretty much sea water a few feet down on the costal areas. It’s a big problem as sea levels rise cause Miami can’t just wall off the ocean like New Orleans has done since sea water will be seeping in from the ground.

And once the garage was finished and before the Tower start vertical construction… 6 buildings around the garage happily collapsed the moment the developers broke the champagne bottle to celebrate the occasion! 🙃

This is necessary in order for other developers to learn from them and in turn build better and deeper buildings in Miami. This is nothing but a learning experience

They should cancel the underground garage and go with a pedestal. Wouldnt they want to avoid flooding and potentially millions in repairs down the road?
