I wouldn't call this an "engineering disaster" but tragic none the less.

Most likely the investigation will find that hot work wasn't adequately managed.
 
The Getty photo collection has a very good visual coverage of the fire. Link

The restoration work at the Notre Dame Cathedral in Paris had been entrusted to the Socra company, specialized in delicate and valuable restorations based in the region of Pèrigord.
 
Only speculation but the cathedral was undergoing renovations. So hundreds of years under the care of the church through wars, no issues. Lowest bid contractor using cheap materials or cutting corners on construction practises and there's a problem.

So I wonder if the contractors or any parties insurance will cover the damages, or will it be upto the taxpayers. Also if the contractors end up going to court will the contractors just go bankrupt and put all the workers out of work.

Well ... not exactly!

Having had the good fortune to stand in the Notre Dame it is a real tradegy that the stained glass appears to have been lost. I was only a child but the beauty of the light streaming through those windows is firmly etched into my memory.

I suspect most everything structural can be rebuilt but I doubt the stained glass can be reproduced in all it's splendor. I lived outside Paris for a couple of years and spent many a weekend in the heart of the city. I probably spent 4 or 5 days in NDdP altogether and have been up in the towers. Because the spiral staircases are narrow and worn, you ascend in one tower and descend in the other. While I was at the top, looking at the bells, etc. I saw a very elderly woman who had a great deal of difficulty walking with a cane. I have no idea how she made it up all those steps and hope she made it down.

I saw a quick news clip that a couple of folks were pledging about $300 million to restore it. I don't have any grasp of whether that will be enough or not - I'm sure France, and other countries, will contribute as well.

Also learned that, thankfully, all three rose windows survived.

That's great news, I just assumed they were gone.

From the pictures in the item below, it appears that the fire damage inside the cathedral itself may not be as bad as what it could have been:

Here are some additional images from inside the cathedral showing the extent of, or lack of, damage:

More 'disaster' than 'catastrophe'; thank goodness.

 
Probably owes to not much was really flammable. Then the flames had to work against rock.

I can't imagine every window has been photo cataloged in detail in the past. There are thousands of hobbyist stained glass makers in the world. I'm betting a lot would like to be able to say they have a window in Notre Dame.

Just to correct the record. Le Bras Freres now appears to be the main contractor. Socra is doing restoration of the ?copper/bronze? statuary that was removed from the roof prior to work commencing on the spire. Link

One source has stated there isn't any electrical for work at the location where the work was commissioned, so everything electrical or pneumatic likely involving a number of generators & the like hoisted to the roof.
 
cab- I bet there's a stack of reports to the Fabric Committee recommending upgrades to the fire suppression systems that were shelved, and are rapidly heading to the shredder as we speak.

Fantastic news about the windows, they don't build 'em like they used to eh? [wink]

Any structural/materials people got any insight into what the effect of the heat could be on the stabillity/integrity of the stone structure?

Since the most intense fire and flames appears to have been confined to the roof, with only falling debris making it into the cathedral itself, it's possible that any heat damage to the masonry may be confined to only those parts of the building where the wood that burned interfaced with the building's stonework. From the photos of the interior released so far, it would appear that there was very little actual fire inside the building and certainly not in proximity to the load bearing walls and pillars, at least not near their base. The only fire near the base of these parts of the building appears to have been the burning debris that fell from the ceiling and roof, and while a large percentage of the roof was destroyed, it was not the entire roof.
