One concern would be that its such a specialty structure that if Sonic didnt renew I suspect you would almost have to demo and sell the raw lot?

Just some ideas if you dont want to demo the vault.  

Demo.

Contingency of $35000 for other issues like demo, landscaping, unexpected issues. 

It was gutted to the studs when we bought it, so no demo/cleanup costs to speak of.

I do demo, tile, drywall, painting, flooring, lighting, shiplap, trim, etc.

Work harder on your demo company.

Hi Randy,You will need to get a few quotes from local companies.How extensive is like how blue is the sky...there is no way to define it.The old system will need to be demo-ed and removed from the premises, and etc....You might want to look into a couple of min-split systems.

3 weeks for a FULL set on construction drawings including all your site plans, MEP, structural, surveys, demo plans, tree surveys, drainage, ect. is pushing it to the max...6 weeks is more realistic with all the work going on today.

My only experience is in building a brand new home with a new foundation.I am having a hard time understanding the order of events on an add-a-lvl as it seems more complicated than a new build.When should I demo and am I just bringing the entire interior to the studs?
