One of the right of way closures for crane installation was extended today until 04/30.

[The ATX]

The dates on the right-of-way closure permits for the crane installations have changed again. One crane is scheduled to go up between 04/28 & 05/04 and the other between 05/01 & 05/07.

That is some black looking dirt.
Was this site a coal seam? (kidding)

It is called shale, it’s classified as rock but soft in comparison to limestone

God god The Republic looks so sexy, along with Indeed on the other side

Interesting little cocktail bar going in at the old Miller Blueprint building.

Apologies for the poor quality.

That's a hell of a hole. It could easily swallow almost every low rise in that photo.

Think of how impressive the proposed Masonic Lodge tower would look compared to all the chunky office towers around there. Even 6XG will be pretty fat in comparison.

The dates for the crane installations have tightened up a bit.

Crane #1: 04/30-05/04
Crane #2: 05/05-05/08

It's not too late to change plans and make the giant hole a giant pool.

Can’t wait to see the cranes go up for this one!

I'm curious to see what that Incredible Hulk crane base is will look like with its crane. I've never seen such a huge crane base.

I thought all cranes had the same shaft dimensions. How deep are the average crane foundations?

A tall one.

My guess would be that they need to be able to clear 300 w. 6th which is about 330'. JE Dunn did a free-standing tower crane for the Kansas Capitol restoration which I think was about 340' and a similar crane just came down at the Oklahoma Capitol restoration. Does it say on the permit the initial free standing height? You usually see those bigger tower sections used for the bottom few sections when a tall freestanding height needs to be achieved.

They don't have special foundations for themselves. Most of the time their foundation and the building foundation are one in the same.

We've had cranes that tall here before. There are some here now that are that tall that aren't yet attached to their building since it's still coming out of the pit. One of Riversouth's cranes is 320 feet. Also, there's no reason the crane needs to clear 300 West Sixth, especially since it's on the north side of 6 X Guadalupe's block, and 300 West Sixth is on the south side of its block. One of the cranes for the new Brackenridge Hospital was also 320 feet. I think the height of the crane and it being erected at its full height has more to do with how much room they have on site and their ability to have a staging area for assembling it. Also, cranes of all different heights are attached to their buildings with bracing, so their height likely shouldn't affect their shaft size. All of the other cranes here appear to have shafts that are no larger than even the tallest ones in say, New York.

I was tired when I wrote that last post and I have nothing else to do right now so I'll go into more depth.

Sorry for any confusion. To me free-standing = height where the crane can stand without needing to be tied into the structure.

If you go back and look, the Brackenridge crane had similar sized sections on the bottom to achieve its height. RiverSouth's taller crane actually has different sections on the bottom too, they just look different for Terex/Peiner cranes then they do for Comansa (less obvious to the untrained eye and more uniform for Terex).

I went back and checked and it says that the crane along Guadalupe St. will be an lc400 which I'm guessing means it is a Comansa 21lc400. I found the load chart for this crane and it says you can achieve a freestanding height of up to 381 feet in part by using D56 tower sections on the bottom. If you Google 'Comansa d56 tower section' for me the second result is a section that looks exactly like the one in question. D56 and D66 are the sections are used for the Comansa lc3000 series cranes which are typically used for industrial construction and is not the crane on the permit.

Ultimately we'll just have to wait and see what they end up putting up. But that's my (more detailed) prediction.

Also, there's no reason the crane needs to clear 300 West Sixth, especially since it's on the north side of 6 X Guadalupe's block, and 300 West Sixth is on the south side of its block.

I'm not that familiar with buildings in Austin so I could be very wrong, but 300 West Sixth looks to be the building right across the street from the large crane base? I Google the address and its the building southeast and across the street from the site. Being that close the crane will need to clear it...? Unless its a luffing crane which it doesn't appear to be.

Also, cranes of all different heights are attached to their buildings with bracing, so their height likely shouldn't affect their shaft size. All of the other cranes here appear to have shafts that are no larger than even the tallest ones in say, New York.

This is true.

I started Googling crane info this morning to figure this out. But I lost interest rather quickly. Thanks for following through.
