For views, I'll look into that parking garage on H-Street.

Yeah, either we need to have a get-together or somebody needs to recommend a place that would be good for shooting the implosion. I have a friend or two who wouldn't mind getting up early on a saturday morning to see a building implode, I mean, how often do you get to see that in your life (if you're not in the implosion business, of course)?

I'll definitely find a way to watch this. I'll have to be at work around 8:30 or 9:00, so hopefully it will go off on time.

First of all, I plan to publish these pictures on the web. Therefore, I won't be on private property unless I'm either invited, or I get permission to be there. I would love to get the entire building in the photographs, but due to other tall buildings within the no admittance zone, it's going to be hard to find a place on the ground that allows the full view. I also would prefer not to be shooting into the sun. I'm afraid all of The Tower residents will have problems with the sunlight. I'm also not real sure if there is a complete unobstructed view of the building from any floor in The Tower. I always remember the Petroleum Building being in the way. I hear that the command center will be in Federal Plaza, but I think that is a no photography zone, so I'm not sure the public will be allowed to take pictures from that location. It will have an unobstructed view of the entire building and people there will not be looking directly into the rising sun.

Jonny, you ask how often do you see an implosion live? I think I've witnessed 8 during the course of 34 years. I did miss the implosion of the smokestacks at the TXU Power Plant.

I wont dispute that the tower is unattractive and wore out, but I still hesitate that its going down. Anyone can tell by my icon and signature that I'm the tower's biggest fan lol. Wouldn't it be ironic that i buy a raffle ticket and I end up the winner that pushes the button? I guess if anyone should bring it down, it should be me. glare.gif

I'm not sure how you would get permision, but I've got a nearly unobstructed view from the 39th floor of Burnett Plaza. The Fort Worth Club blocks my view of the North side of the bottom 6 floors. I would imagine from the roof of Burnett Plaza you could get a pretty good shot.

I have a great view from the south side of the Tower, but John's right (as usual) about the sun being almost directly in line with the building, so it's not so great for photography. I'll watch from my window or balcony, and look at other people's photos/videos.

I thought about this, too. I have a small view from the 14th floor of Burnett Plaza, but I figure from the roof the view would be great.

Unless you ar "MR. MAINETENANCE Guy" at Burnett, there is nooooo way the mgmt. there is gonna let "x" amount of people up on that roof. Maybe a professional photographer. Does anyone have access to a small helicopter for photo taking (Magnum PI style). Perhaps we could land on top of a building, take some quick pic's, and then get the heck out of... COWTOWN. biggrin.gif

Let's move on this, and get THE BEST LIVE picture possible. Time lapse, video, or still series picture. MUST post it on the FW FORUM ASAP! Group effort and group glory.

I'm sure Star-Telegram photo sales could help you. I don't know what they charge, but their number is on 2A of the paper in the fine print under the lotto numbers.

There is a lot of interest in this photo. Some of it can be made out in the version you have posted.

In the photo the Federal building is under construction in the mid-foreground. The latest layer of hideousness is going up atop the SBC building. I guess it was the AT&T building then. The corner of the Star-Telegram that is visible reveals the vertical-reading electric sign on the corner of the building, and the porch-like contraption that's on the corner of the building these days is not present. East across Taylor Street from the S-T, the Worth Hotel still stands.

Above and around the Electric Company building visible just this side of the courthouse are Striplings, Monnigs, and, I believe, Leonard's. Big Fort Worth retailers, the last of which seems to be sputtering to oblivion.

City hall is not present, but the old deco library is.

The photo is dated April 8, 1965.

Because of color positions and such, the photo ran in the paper in black and white. The original is in color.

johnlp,
The Fort Worth Public Library downtown is a great resource for old photos like this. In the basement they have thousands of old photos cataloged. Of course I don't know if they have this exact one but I'm sure there are many others like it. I have about 30 framed old black and whites of downtown which span probably at least 100 years. I love them and guests enjoy them. So try the library.

Out taking pics today of Landmark Tower, I ran across a friendly man observing the work who has some sort of association with XTO. He's not an employee, but apparently works with them at a fairly high level. Chatting with him, he went over the plans for the demolition process, how the charges would bring the building down in a certain way, the purpose of the cables being wrapped around the exposed base (you can see them from 7th with the red tags hanging from them - if I recall, he said they're designed to contain the base during implosion; anybody know more about that?), plans for containing the debris and the aluminum panels, etc.

He told me that there were plans for a new building on the site. When I described the talk of the infamous 50-story building, he seemed to think that was a little bigger than the reality. From what he said, a 20-ish story tower with a (separate?) parking garage is what was in the works. He didn't know a time frame specifically, and didn't have all that many details on the building. Just that he seemed fairly certain that there would be a building there again.

Now, I don't know the guy. He seemed nice enough, but you never can tell if this was just as speculative as the 50-story talk was, so take it with a grain of salt. From his talk, though, he seemed to be pretty sure of a new building.

You're right. To hell with economics, build something a hundred stories tall with a 500 foot spire on top of it. I don't care if it sits empty because no one can afford to lease the space. An empty tower sticking out like a sore thumbs beats a nice looking mid-rise any day of the week.

I like the last past Bob Ray Sanders says. Time has passed it by as the city becomes home to a new generation of skyscrapers that will continue to redefine the skyline.

I hope over the next few years bold new towers will outshine all other cities in the metroplex.

Well, a mid-rise sounds a lot better than an empty parking lot! I think anything XTO builds will have great architectural quality, they already have a great track record. I would also like to see them incorporate a public park in the block, to kind of unite all their buildings and give downtown workers/residents a greenspace to enjoy.

The Landmark Tower or CNB was built when I was a young boy and it was always my favorite building. My uncle worked for his brother's contstruction company that was one of the contractors that built it, Rambo Construction. My uncle operated the construction elevator that is visible in some of the pictures shown earlier. We went downtown almost every day to watch the building go up. I remember him walking up the external fire escape and going up the external construction elevator. He talked about the building often. Several of the construction workers were killed in accidents during the construction. One night, a storm came in and he got a call from his brother that security had called and materials were blowing off the floors. They went down there in the middle of the night and went floor to floor securing what they could. When the building was nearing completion, he would tell how on a clear night you could see downtown Dallas from the roof. The clock when it was completed was designed to stop rotating when the wind speed reached about 50 mph. It also rotated one revolution a minute. While the building is in terrible shape, it will be very sad for me to see it come down. I've got an old color post card from the early days with the red brick streets and old cars that I will post when I have time to figure out how to do it.

I saw some great views of the top of the building and clock from the Petroleum Club. You look right down at it from a couple of blocks away. It would be a great view to watch the building come down.

You know, a good bit of triva and just general interst, does ANYONE know about the mechanics of the clock? How it worked, how did it keep time?
I was told that it used 480 flood lights (per clock side) to make the digits including the (smile.gif colon mark.
It would be great to see some clock construction photos! When the CNB letters were removed in 86-87, there was an awesome color photo in the FWST showing the "C" being removed. I'd like to find that pic! smile.gif
I was also told the the body of the clock was made of stacked "I" beams. Not sure how correct that is.
Blue prints would be cool to see!

I don't have blue prints but the clock was made of "I" beams. They were taken up to the roof individually and assembled like an erector set. Gears rotated the clock and they eventually wore out and the clock stopped rotating. I don't know what the mechanism was that kept the time either but it was always accurate. The clock was extremely heavy and not a part of the original building plans. It was originally going to be all brick but when they decided to add the clock, they had to use the aluminum curtain wall to cut the weight. They also had to reinforce the foundation of the building.

Some of the panels developed a red tint after a few years, but nothing like it is today. The windows weren't tinted in those days so it was pretty clear which ones had the blinds up.

I know these are professionals doing the demo, but for something this tall, what are the chances for something to go wrong as it comes down? I mean if it starts to lean over instead of coming straight down and such. The damage to the surrounding buildings and streets would be horrific.

With the debris expected to be six stories that is certainly a lot of opportunity. I think the leaning would occur most easily if one side of the structure remained intact while the others were cut. I would deal with that by making sure that each circuit went to charges on all four sides. That would be a simple beginning. I'm sure there's a lot more to it (back-up circuits, maybe).

The assymetric influence of those two big transfer girders will have to be dealt with, but I'm sure cutting structure on the third floor will mitigate their influence.

Those are great pictures, John. Thanks for posting them.

I saw something on the Discovery channel related to this kind of demolition. They said the contracts are often written to state that the blasting company's obligation is to reduced the building more or less to a pile of rubble. If the building only comes halfway down or something along those lines, it's still the blasting company's responsibility to finish bringing it down. I've got to believe that could be an expensive proposition.

Wasn't there a building in Sioux Falls that was supposed to be imploded recently that didn't go all the way down as expected? Anybody know if that job ever got finished?

It's my understanding that the demo company is setting Landmark Tower up to fall ever so slightly (and I do mean slightly) to the west, to bring it down towards the trench and away from the Simpson building. Don't know if that's true, but that's what I've heard. Could be wrong.

A recent example of a failed implosion:

http://www.nbc10.com...568/detail.html

In the late eighties or early nineties a set of grain silos on the near west side where So7 is now failed to implode properly. They dropped about one story and didn't collapse. They sat there in that state for some time.

I understand that grain silos are built to contain gigantic pressures inside. In some ways they are quite a bit sturdier than your average skyscraper. This strength appears to be achieved less through artful engineering than by a kind of blunt force approach: They use honkin' thick concrete.

And for some successful implosions:

I always find 'em kind of sad.

By the way, do the stagings in front of the Baker/Simpson building and beside the Waggoner building have something to do with the implosion of the Landmark tower? Kinda soon after the restoration for the Simpson building to need work.

I am not an expert in buiding demolitions, and yes, things can go wrong with implosions. However, all of these demolitions are extremely controlled. In most early 20th Century skyscrapers that were imploded, the building had a wider base and a tower section. The base was demolished and the basement was excavated, then the tower was imploded into the already demolished basement. Larger floor plate buildings that are shorter than they are long are simply imploded into themselves. Most of the implosions of tall buildings are designed to drift as they fall toward the area that has the most room.

Since the Landmark Tower had no lower and wider base, the remainder of the block is being used for the demolition process. The excavation that has already occurred on the north side of the building to get equipment out of the basement and sub-basement will be used as the area for the building to fall into. Over the next month, you will see this hole be expanded to the west side of the building and more of the rock and debris piled up along Throckmorton and 6th Streets. These actions create a hole to fall into and a barrier to lessen the damage to other buildings. This will allow the building to drift toward the excavated areas and away from the other buildings across Houston Street.

As for grain elevators, the reason their implosions take time and seem difficult is that they are designed to be explosion proof due to spontaneous combustion of the grain. That is mainly done by pouring the concrete extremely thick.

I hear that the command center will be in Federal Plaza, but I think that is a no photography zone, so I'm not sure the public will be allowed to take pictures from that location. It will have an unobstructed view of the entire building and people there will not be looking directly into the rising sun.


Has anybody learned whether or not photographers will be allowed in the Federal Plaza? If not, who would likely know this information?

Also, if the Plaza is off limits, where's the next best location for a ground-level view of the implosion?

Thanks. biggrin.gif

If the Plaza is off limits, then I would say that 8th & Houston, diagonally across from the W.T. Waggoner Building would be the next best spot. However, I still find it hard to believe that spectators would be allowed that close. From the information issued so far, that intersection appears to be outside the boundary. Personally, I think that when the logistics are worked out, the southern boundary of no admittance will be 9th Street. Already, the area includes two full blocks west, north, and east of the tower's block. I'm thinking the area will be expanded to 2 full blocks on the south. If that is the case, there will not be any point on the ground, except in Federal Plaza, that will allow a full view of the building. I'm also afraid that we really won't know what areas are off limits until that morning.

The safe location is being invited into a residence in The Tower, but we already know that looking into the sun will probably not yield the best photographs.

Birth of the CNB. From an original Bill Wood print from 10-3-1955 smile.gif Look at that beautiful Skyline! Picture was shot from roof of Montgomery Ward.

IPB Image
Also of interest in this print is the construction of the Clifford Herring Sound Equipment Company at 1705 W 7th (bottom right corner). 10 years later this would become the home of KXOL. smile.gif

That is one great shot! Do you have more of the construction of the building?
