Don't know if anyone has heard the news about the girders that twisted during install during a bridge replacement in Edmonton. This is a link to the webcam that shows the 3 ltm 1400's that have been holding the girders since early Monday morning. They are currently setting up NCSG's ltm 11200 to help fix the mess. 102 ave bridge webcam

By the way, if you look at the 102 ave view you can see the warped girders and the 3 1400's

There have been a couple of good detail pics of it lately with all the publicity over the bridge.

The time lapses are pretty cool to watch and see the different machinery brought in. What was the Hitachi long reach exactly? (at the start of the Groat Road time lapse)

what actually happened that those beams ended up that way. what are they planning to do to fix it? they have all those cranes hooked to it but I am not sure of what they are attempting there. seems like a precarius deal because that is big big iron up there. if you look close you can see all of the bracing is bent, or broke, and hanging so it puzzles me a little bit

Those operators from both LTM1400 and LTM1300 must love their job, sit and hold a load for a couple of days. 1 reason i want to be come a operator.

The beams are all bent to crap and beat up. Looks like they need to be lifted off and replaced.

be careful what you wish for. I have sat in a crane for days in a chemical plant or steel mill and made one lift or maybe 2. i HATED it!!! 16 hrs seemed like a month. but on the other hand putting up iron or something 8 or 10 hours seemed to fly by. hated driving pile too but only had to do that a few times. but back to this fiasco these guys have going on with the bridge. are they going to just try to cut big chunks of bent up beam out and then leave the straight ones and build some kind of temporary columns under what is left of what they cut out. I thought they were initially going to just use 3 cranes an lift the bent ones out whole but that big crane is hooked up to 2 beams. hmmmm

The engineers are still trying to find out why the beams all of a sudden buckled. The 3 cranes are left there to hold the girders in case something happens. They brought the 11200 in to slowly lift the first girder to see how the beams react when the stress is taken off. The girders did show signs today of rebounding and the bracing is now going to be cut off and each girder will be lifted out one by one by the 11200 to see what they can do for a repair job. The contractor is eating this bill and so far just getting the 11200 to site which is about 30 km away from its yard has cost 15 grand and it took 3 days to set up the crane so it's not going to be cheap.

why is the contractor paying? to me that almost implies some sort of liability, and i am not saying they are it just seems strange to assume the responsability for that type situation if this event happened through no fault of your own or your guys. interesting problem thats for sure. one thing i did notice was that the size of all the knee bracing between the beams looks pretty small for the angle that its on. im no engineer though

Yea I do not know all the details about why the contractor is paying but I am assuming they have insurance for these purposes. The city of Edmonton was freaking out because they didn't want to get stuck with the bill because right now the economy in Canada is in the toilet from this oil crash and nobody has any money right now. The 11200 runs around 10 grand a day to operate and if these girders need to be replaced it will be a one year waiting period plus costs of replacement. What is strange is that all the girders were in place with bracing and literally at 2:10 am they were straight and by 2:15 they buckled, so there is stress on them for whatever reason and now they are going to try and relieve it.

I am amazed that those things are actually returning to shape. Impressive.
