capnmcbarnacle Posted August 16, 2014 Share Posted August 16, 2014 oh boy, this is hilarious! Can we change the thread name to "609 Main at Texas: Hines's Whataburger Tower?" I like the idea of referring to it as the Whataburger building. Not sure Pickard Chilton would love the monkiker, but I really mean in the most endearing way. 2 Quote Link to comment Share on other sites More sharing options...

rechlin Posted August 17, 2014 Share Posted August 17, 2014 They're still working 7 days a week on this, starting at 7:30am or so. When I walked by this afternoon (a Sunday!) I counted 36 people on the site. It's astonishing how thick the rebar is -- if you look closely, you can see workers walking around underneath/inside the rebar. Looks like they are getting close to finishing the rebar placement, so I'd think the mat pour can't be far away. It's going to be an insanely long pour, I am sure.

Sky-guy Posted August 18, 2014 Share Posted August 18, 2014 that looks way deeper than it did in previous pictures. Quote Link to comment Share on other sites More sharing options...
bobruss Posted August 18, 2014 Share Posted August 18, 2014 Rechlin, great shots. When I blow the image up and magnify it,there appears to be a man in an orange shirt walking below the men working on the rebar bundles. Am I seeing things, or is it, that thick of a slab?

Purdueenginerd Posted August 18, 2014 Share Posted August 18, 2014 Sunday morning? Don't they usually do those overnight to avoid the heat? You can control mix design temperatures a multitude of ways. But if that is in fact a monolithic pour...the time of day won't matter much. That pour will push 140 degrees at night. The day time pour will reduce their working time due to heat, but at the bottom of the form, that won't matter. I would opine that theyre timing the start of their pour, so that the end is at night, thus maximizing working time for the crews finishing at the top. Hope we get some good photos of the pour... Thats a massive one. My biggest concrete pour is 500 cubic yards. This looks like 15,000. 1 Quote Link to comment Share on other sites More sharing options...

hindesky Posted August 18, 2014 Share Posted August 18, 2014 Rode my bicycle by there on Sunday morning and talked to a supervisor, he said the pour will happen Saturday morning and it will have 3 tower cranes. 2 Quote Link to comment Share on other sites More sharing options...

rechlin Posted August 19, 2014 Share Posted August 19, 2014 According to a construction worker on the site, the mat pour starts Saturday noon, will continue on to Sunday, and will involve eight pumper trucks. 2 Quote Link to comment Share on other sites More sharing options...

ClutchCity Posted August 19, 2014 Share Posted August 19, 2014 (edited) Yea it'd be interesting to find out how many millions of pounds of rebar they are putting down there. Edited August 19, 2014 by ClutchCity Quote Link to comment Share on other sites More sharing options...
rechlin Posted August 19, 2014 Share Posted August 19, 2014 A guy on site said 25,000 tons of rebar, but I'm guessing that's for the entire building and not just what has been placed for the mat foundation. Quote Link to comment Share on other sites More sharing options...
Purdueenginerd Posted August 20, 2014 Share Posted August 20, 2014 (edited) A number 11 bar is 5.31 lbs per linear foot. 25,000 tonnes would be roughly equivalent to 9.4 million lineal feet of No. 11 bar. A standard Houston block is 330ft by 330 ft. Even if I had 1 foot spacing, both ways, and 2 mats that adds up to 435600 lineal feet- or 1,000 tonnes. 25,000 tons, seems like too much even for the full tower. B/c they likely be using Number 11 bars after the first few floors. No 18 bars are 13.6 lbs per linear foot. Based on the pictures it doesnt look like No. 18 bars to me. But I could be wrong! I'm totally playing armchair engineer right now without any knowledge on the load calculations for the foundation. Thanks for the pictures again though... keep em coming!

lockmat Posted August 20, 2014 Share Posted August 20, 2014 From Hines' fb page609 Main at Texas, Hines next iconic building in downtown Houston, is 3 days away from the “mat pour.” On Saturday, 180 concrete trucks will line up to continuously pour 14,000 cubic yards of concrete for more than 17 hours. The 48-story office tower is scheduled for completion in early 2017. http://bit.ly/1mlG2J2 1 Quote Link to comment Share on other sites More sharing options...

bobruss Posted August 20, 2014 Share Posted August 20, 2014 I wish the oxblue construction cam featured 24 hour live flow. If I remember correctly it seems that you only get a shot every once in a while every day, but live feed would be interesting to see. They do have a feature that allows you to watch the time lapse images but I don't think there will be enough of them to see the trucks going in and out. I wish I could be there to watch but will be at work.I'm really not sure how their cameras work but I do know you don't see movement in the images. Anyone know for sure.

Grizzly46 Posted August 20, 2014 Share Posted August 20, 2014 It appears that they laid 2 levels of rebar, spaced about 6-7 feet apart. Is the concrete going to be solid over both levels (one continuous pour) or are they creating two separate levels? Quote Link to comment Share on other sites More sharing options...
BigFootsSocks Posted August 20, 2014 Share Posted August 20, 2014 If there were two desperate levels there would be forms in place which I don't see any, so it's probably one massive slab. Quote Link to comment Share on other sites More sharing options...
nativehoustonion Posted August 20, 2014 Share Posted August 20, 2014 It seems they are doing the foundation for the 48 story tower. Because the garage does not need a deeper foundation. Could be wrong just viewing the pictures. Do you have big feet? Quote Link to comment Share on other sites More sharing options...
Purdueenginerd Posted August 20, 2014 Share Posted August 20, 2014 This is for sure the foundation slab for the high rise. Parking garage loads are puny compared to the skyscrapers. Quote Link to comment Share on other sites More sharing options...
