From the auction thread:

Judging by the exalted nature of his response I'd speculate that he's lost in another reverie about the glories of things concrete.

These are pictures I took last week at the new National Fire Lab on the NIST campus in Gaithersburg. It was about an 800 cubic yard pour on an 4 foot thick elevated deck (!). The pour started at 4:00 AM and we were poured out around 9:00 or so. We used two 42 meter concrete pumps which were fed almost continuously by two ready-mix trucks at a time.

The grid on top of the slab was to hold the 1200 galvanized sleeves in place. The tolerance for placement of the sleeves is under 1/32" in any direction (X/Y/Z). Each sleeve weighs approximately 90 pounds. This is in addition to the 1900 tons of wet concrete and 160 tons of rebar (again - all in an elevated deck 10 feet off the 3' thick foundation mat).

Beyond the reinforcing steel, running through the middle of the slab are 27 runs of bonded 6-strand post-tension cable (approximately 2,100 LF of tendon or about 2.5 miles of individual strand). After placement and curing of the concrete, the tendons are individually stressed with a hydraulic ram to carry 257,000 pounds of tension each.

Tis glorious, no?

I love my job. It's like playing with giant Legos.

Not the biggest pour I've ever done on one of my jobs, but certainly the most complex.

Pretty sweet Tony. Don't 800 yard pours just make you all excited? We'll have to talk more on Saturday, I don't want to bore the rest of the CCA, but I'm interested on how your formed the deck.

Thanks guys.

Jon - Fortunately, the deck has 16" walls at 10' OC pretty much all the way across (doorways breaking them up, so the spans weren't too crazy. We used Peri with an extra layer of their wooden stringers. It was still a ton of shoring.... and removing it all out of the 100*+ basement is going to be fun.

Wait, what's your job again? Where are you in the picture? :)

I'm a senior PM for a concrete construction company. I have an OSHA 30 card, but unfortunately they don't trust me to go play in the mud. :p

He's got the easy job. He's watching:rolleyes:. 1/32" of tolerance in placement for anything must be tough, but I'm sure its run of the mill for you. I'm glad my job will never require me to be anywhere at 4AM.

To be honest, 1/32" tolerance is just plain absurd for concrete construction. I blame Matt.

Oh, and while we're at it, I blame Maryland. :p

I remember those days! It was all a'holes and elbows when the concrete came. Favorite part was when it was all poured and the rabbit is shot through.

Huge job in the pictures. Interesting to know that you have such a good time outside of second Saturdays. No wonder you fish room looks so 'concrete':D. Your stands are probably built to last foreverrrr.

It's kinda funny... everyone I know that works in commercial concrete construction.... LOVES their job... of course they aren't doing the labor part :lol: Just watching it :lol: I think it helps that none of them have lost their jobs during this economy... kinda weird actually.

1/32 is a little retarded :lol: Reason?

Tony have you gotten a lot of jobs due to the earthquake? Just curious... yes, it was small but I'm sure a lot of the old buildings foundations were damaged etc...

I work for a General Contractor here in town (yes I watch the craftsmen work as well), and there hasn't been much new work because of the earthquake, but we have seen a lot of warranty calls. One of the buildings I built 9 years ago had some of the joints in the brick veneer open up and cause water leaks. This was the 4th warranty call that the mason had been called on since the earthquake.
