"outside of large scale public infrastructure projects construction is entirely predictable and safe now."
My last three home remodels and the recent corporate construction we are in the process of finishing beg to differ with you. Heck, every house flipping/building show on HGTV disagree.
The same holds true for mass produced items, especially once they've been deployed. My last pick-up truck was occasionally a nightmare to get parts for since what was on the truck didn't match what the dealer/auto-parts store said should be on there. Figuring out what brake pads to get for the after-market brakes took myself and the old guy behind the counter at autozone an hour and a half of eye-balling and trying stuff.
Building anything is hard, and when it comes time to change/fix it it become worse, especially if you need to keep using the item in question during the period that you are "improving" it. You never know what you're going to find once you start poking holes in the walls or pulling parts off.
