You might have a case but generally speaking, if it's your fault then you're liable, if it's not then you're not liable regardless of what's in the contract. But say you build a deck, everything is to code, per prints, inspected and signed off. Then a mole comes and digs a hole under one of your piers causing the deck to sink. Would that contract protect you? You shouldn't be liable anyway so I don't think that contract is doing anything, but like I said, ask your attorney.
It doesn't make a lot of sense to me to just throw in random scenarios trying to protect yourself. You can list a thousand different things and still not cover everything. What about riots? A car or a plane crashing into the house? Someone puts in a hot water tank that explodes and goes through the roof? Stuff out of your control is supposed to be considered an "act of god", legally, then the homeowners insurance takes responsibility.

Well if I had a code violation and the home fell down it wouldn't be for earth movement it would be for the code violation. But if I built the deck as per plan and prescriptive code and it still fell down this is the issue I'm speaking of. Absolutely I'm liable for code violations or deviation from the plans. But again the building didn't fall because of an earthquake. It would theoretically of fallen from the missing hardware.
