Roof Collapses at CDG
Part of the roof at terminal 2E has collapsed killing six people.

sympathies to those involved.

I regulary use BHX-CDG with BA and that uses 2B. From the pictures, it looks like the part that collapsed is similar in design to the departure area gates at 2B, ceiling with curved glass from ceiling to floor, next to airbridge to plane or to the bus for the smaller aircraft.
Under the curved glass is seats and the air conditioning vebts next to the window, with further seats and the security scanners under the actual ceiling. Three police have died, which might have been the guards at the scanners.
Terrible.

Dutch radio reports 6 have died, including a number of police oficers who were in the process of sealing of the area after a crack was discovered in the roof.

Reminds me of the Transvaal accident in Moscow.
Swedish media claim that one Chinese and one from Ivory Coast where among the injured, may the unfortunate ones who lost their life today, rest in peace...

I am sitting in my office looking out of the window at it, there is a large amount of damage to terminal 2E, one whole section has collapsed.
It’s occurred where the walkway from check in connects to the departures area. Part of the walkway has collapsed as I can see it hanging down at an angle and that appears to have taken the whole section of the departures area out with it.
So far our flights (from 2F) have not been affected, but if you are travelling allow extra time as you are faced with a long walk to the terminal as they have closed off the road to 2F & E.
Very sad day.

No earthquake and this time of year obviously no snow, what about rain water accumulating on the roof?
It defies belief that a roof could simply collapse of its own in this day and age. How about sabotage?
Sympathies for thei victims and their familes

My better half arrived back to CDG this morning from her AF flight and was informed by their flight coordinator of the accident. Other than that, she was not able to find any information. It was frustrating for her and she wanted to know if any of her colleagues were involved in the accident or not. Aeroport de Paris was not providing update information. The weather at the time the accident happened was fine and did not cause the collapse. There was no rain and no wind.

Wino, you live on the west side of the Atlantic. We've had our share of concrete collapses during construction, though I don't know of a collapse in a new structure.
Some days I walk down the hall of the Building Research Division at NIST - they investigate construction failures- and see their gallery of photos of crumpled and twisted buildings, bridges, etc. They do happen here.
One of the press stories on the CDG collapse mentions "security" inspectors delaying the opening of the building. That is probably a mistranslation and should read "safety".

Could be a whole range of structural reasons for this, but should be straightforwardly determined by building engineers on the spot.
Looks like the sort of collapse you get when prestressed or post-tensioned concrete fails (you put the reinforcing steel under stress, then pour the concrete over it, then let go. You can do lighter structures this way).
Also looks like trucks can be driven underneath. Any likelihood of them striking the support columns or the underside of the structure ?
How long has the structure been up (see it opened a year ago). With concrete construction there's always the chance of corrosion getting into the reinforcing steel inside the concrete during the construction stage.
Was it a particularly hot day in Paris yesterday?

There have been a few concrete collapses during construction over here as well (though not to recently, last one was in altantic city, a parking garage I think)
But not buildings that were competed as far as I know.
Strange strange....

RIP all souls lost at CDG today.
Let the experts find the reason for the building failure and let other buildings of similar design and fabric have its weakness identified rapidly before something like this happens again in France or elsewhere in the world.
Were there any questions about the build? the contractors? doubts expressed?

Dunno. But the main contractor seems to have rapidly removed the pretty CDG terminal pics which were on its website earlier today.

News reports are vague as to technical details (what a surprise!). Was the structure reinforcement insitu, precast, pre or post stress? The stressed stuff allows for a very light weight structure but as a result will have less redundancy for errors in design or construction. Whichever type, such a collapse, like the tragedies more commonly reported here, would require a chain of errors and mistakes. Normal advice about waiting for investigation report applies.

PARIS AIRPORT EVACUATED
Charles De Gaulle airport in Paris has been evacuated after cracking noises were heard in the roof - a day after its partially collapse, killing four people.
The noises were heard on either side of the 30-metre section of futuristic terminal 2E which gave way on Sunday morning.

Excerpt from New York Times article:
The concrete shell, built by the French construction firms Eiffel and Laubeuf, was constructed in rings "with three interlocking elements, positioned one next to the other," the news release said. To simulate the pressure on an underground tunnel that keeps the concrete tube intact, the news release explained, steel hoops were attached to the outside and carbon fiber reinforcements were glued onto the shell.
