Tragic accident yesterday in Trondheim, Norway. A bridge under construction collapsed while at 1 3rd of the poor. Traffic was going under the bridge. 1 car go crushed and the woman driving was killed. Also 1 worker was killed and 2 seriously injured.

How is it possible that these things still happen?? How can we ever feel safe while poorinbg such constructions?

Wow, this is just sad

Very Sad. Did you see this happen? were you on the job? This should of never happen for sure.

No. I wasn't there. Its about 14 hours driving from where I live. But we've done 2 bridges like this in my town last year and I must say the scaffolding looked much stronger in on those.. There must have been a huge mistake here since they only where at 1/3rd of the poor.. It should have been strong enough to take 3 times this weight...

In the last years there have been 2 other collapses like this in scandinavian countries.. 1 in Denmark some 3 or 4 years ago  and 1 in Sweden before that.. Also in The Nethelands last year a deck collapsed while pooring. It was about the same scaffolding system.. This stuff is like knitting needles if you imagine the weight that comes on it..

I don't understand why they not learn from these accidents.

Looks like a monolithic pour.   I think they should form it all, rebar the beams, pour them, then rebar the deck and after the beams have gained some strength, say - 4 - 7 days, pour the deck.  the beams  can pick up some of the strain.  In all likelihood, this would require different engineering as it isn't monolithic and the forces of tension and compression would be different.  But it looks like they had the roadway open beneath, that likely contributed to the disaster - not enough support over the span.  Perhaps the rate of pour was too fast on one side versus the other, creating a twisting action.   Whatever the reason, this is something that cannot simply be 'good enough', we don't have time or budget for anything else...

Very hard to even look at these pictures. We all know how fast this can happen.

Prayers to the families.

Just heared that in total 10 other planned projects like this in 2013 are now put on ice. No traffic will go under any poor before they know what has caused this accident.

According to the supervicers the method used for building this bridge is a very common one and used many times before all over the world...

I would dare to say , if traffic was open underneath the supports or lack of under travel lanes would probably be the cause, I never liked the idea of pedestrian traffic under such pours, when catastrophic things happen, innocent people get hurt or die, prayers go out to all families affected by this tradgedy.

"pre-cast Beams" only way to go!

yep !!!
