What type of insurances can you have for a house build?

[puntloos]

As we all know, when building, any delay on one front can blow up schedules across the board and cost time and money. Just want to make sure I tick all boxes. Is there affordable insurance against: (just some examples)

 

- Finding an unexploded WWII bomb or buried chemical dump or whatever "historical inconvenience" that we couldn't have known about and causes massive delays?

• Can I be compensated for the delay somehow especially if the culprit is nowhere to be found, or in a ditch, covered in petrol, on fire?

 

-Some human trying to tie me up in court over something. E.g. someone, maliciously or no, says there are cross-twitted hedgewarblers in my rear yard and therefore I can't demo, investigation costs 2 months. No matter if they are right or not, if they tie me up in court it costs money.. so:

• Court/Legal costs
• Cost of delays/replanning?

 

- Builder goes bust, new builder asks way more than original builder

• Won't someone pay the difference?

 

- Deliveries get delayed, even though the orders were made at a reasonable time

• who do you sue?
