New caunduay bridge collapses

I have to chuckle, as my filipina wife said when she saw the pic . . . "what a f--king piece of sh*t" LOL

 

Just goes to show building a house and a bridge aren't necessarily the same thing. Better it failed before it was completed, instead of after it was completed. I wonder whose palms got greased on this one.

 

what's was holding the thing up coco lumbar. No wonder the thing collapsed.

 

Not looking at it first hand it looks like improper rebar and not enough compression strength in the concrete. Does the Philippines even take a sample of the concrete and send it off to be tested?

 

There is an old joke in building business, "Termites holding hands is the only reason that structure is still standing.....guess the termites let go.

 

I think I'll wander over for a look see. They don't seem to understand what happens at a cold joint.
(The fresh concrete does not bond to the dry concrete).

 

That's one of the reasons for the rerod, at least when I've seen skyscrapers being built they can't do complete pours. How is the concrete work done there? Not saying it didn't contribute, but I think it could be the design as well. Concrete is very strong under compression, but not so strong under tension, hence the rerod which gives it additional tensile strength. Generally a bridge is built with some curvature to insure that the concrete is always under compression. This bridge looks like it was flat and essentially sagged. Could also be things like the quality of the concrete and/or shoddy workmanship. In the Philippines.....say it isn't so.

 

On second thought, might make a good dam, though.....lol.
