Casualty Loss w/ Retail Store

I realize casualty loss covers a wide spectrum of disasters but had a question on if it could be interpreted due to negligence from a landlord. Here is the scenario:

Retail store sells high end footwear and displays all of its $55,000+ worth of inventory on the sales floor. Retail store has large glass sliding doors what have noticeable gaps. Landlord, without notice, start ripping up floor and saw cutting concrete in front of store. Concrete dust covers entire retail store and renders $55,000+ worth of inventory unsellable.

Would like constitute casualty loss?
