    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.

    Here's aerial photo from 1962 of the area. Might be the remains of that building on the corner.

    This tower is going to have quite the influence on the skyline from I-10. How many feet is it? 500?

    You guys are kind of debating something that can't really be settled with the information we know. But I'll chime in a few extra points... The loads for a residential tower on each floor slab are normally a lot lower. The Private dwellings for multifamily apartments have live load spec of 40PSF vs 50 to 100PSF for offices (see ASCE 7: Minimum Design Loads for Buildings and Other Structures)609 Main is taller. Taller buildings mean higher wind loadsHigher loads means more hefty construction and design, which typically means more person-hours to complete the projectSpeaking of person-hours, none of us know the amount of labor crews allocated to each project. For all we know, Sky-house could have had 1000 people working on it. (exaggerating). We simply do not know the production rates of various crews.Speaking of Production, we have no idea what contractual obligations are set forth between the GC and owner. Are crews being paid by the owner to work 70 hours a week to complete the project faster or is the normal 40 hours okay? I think, In general, Bigfootsocks is correct. That is mainly because Residential towers are easier to design for, have lower loads, are generally shorter, and are generally less complex projects than a tall highrise office.

    Probably a below grade parking garage.

    Alec, Do you got a higher resolution image on that? It looks like their steel reinforcement for the colums are angled, Am I seeing that correctly or have just not finished setting them in place?
  7. Purdueenginerd
    Thats some quite of bit of hefty shoring on the ride side. I like these photos guys, keep em coming!
  8. Purdueenginerd
    I agree. I was pleased to see the framing for this structure was not wood went it started going up.
  9. Purdueenginerd
    Wonder what theyre going to do with that utility room at the top of the structure (left side).

    you guys are nerdier than me. haha

    Same area, 11/11/1953. You can see the darlings on the corner More photos here http://blog.chron.com/bayoucityhistory/2014/11/rare-color-film-shows-1954-veterans-day-parade/#28275101=0

    I added the picture to Historypin.com https://www.historypin.org/channels/view/46823/#!map/index/#!/geo:29.759334,-95.363128/zoom:20/dialog:279180/tab:details/

    If it's new then yeah, I agree they may have anticipated the expansion. Darn too, I like strengthening projects . Was close to forwarding this to the sales team in my company haha.

    This is going to be a cool project to watch, tripling the height (roughly) of a structure is likely going to require a lot of strengthening work. I'm pretty stoked about the construction photos for this one.

    Those houses were leveled I think when the continental tower went up. It was a parking lot until recently, now theres construction for a believe 5-6 floor condos or apartments on those blocks. This picture looks like its right over Dallas Street. Where the bar "The Refinery" Is today. Side note, I like that bar. Hope it sticks around.

    If I recall correctly, Houston's CBD blocks are 330' x 330'. Which is about average for a lot of cities. I think the reason so many high rises take up the full block in houston is because they can. Plenty of space to build what you want when the existing structures that were there were leveled 30 years ago. That being said, I would opine that once space starts running out in downtown, you'll start seeing less "full block" construction. Thats my 2 cents at least.

    ah youre right. Thanks.
  18. Purdueenginerd
    Here it is in 1964 ( I think). Lets call this the "Before"
  19. Purdueenginerd
    That explains the name of the building! 29 floors of cat perching spots!
  20. Purdueenginerd
    Saw the video on Reddit, nice to see it here as well. Great shots!
  21. Purdueenginerd
    Wowsers! did not know about that gem. Thank you!
  22. Purdueenginerd
    improvements* in the title of the thread. I've never been to this library, is it nice? Worth setting up shop to work there occasionally?
  23. Purdueenginerd
    Maybe the delay is so they can design an even taller building... Like 1,777 ft. /dreaming.
  24. Purdueenginerd
    The rents in those corner units are gonna be insane! Nice building though. Hope it gets built.
  25. Purdueenginerd
    HAHA! Thanks. And also, I agree.
