They have 12 days to figure it out.
I am betting they don't figure it out.
Im no lawyer, but, My concern is that the city gave YOU 15 days. That dose not mean your relationship with the sub-contractor ends in 15 days.
Im NOT happy to tell you this,... and I think there work sucks,,,, but, my guess is: As far as they know they hit a small hiccup and they are still working on the project. they simply have not finished it yet.
I think,,, After the 15 days are up, the work should be re-assessed by an industry professional. At that point, I would notify them again of the deficiency and implore them to work diligently to the projects completion, perhaps add in a claim of breech of contract or state specific grievances. Then give them reasonable time to correct the breech and problem, I would think 15 days?. Most likely they will realize you are not going to pay for garbage and they will walk away. (monitor there progress with a Trail Camera perhaps?) Then you send them another letter adding belief of abandonment and your intent to take corrective action in 30 days. At that point I would be comfortable moving on.
I'm no lawyer but That is how I see it, (:
Hope someone chimes in and tells me I am all wrong about this.
I assume they are good people who just didn't know how to do this job, They are humans to so be as polite and understanding as you can, while still being firm. It is not worth getting mad over even as bad as it is to us. I have to think they were trying to do good but were in over there heads. They have feelings too, Personally I would be as nice as I could about it. They are probably already feeling like crap right now. and there pride is likely low.):
The legal system sucks for both parties, only the lawyers win. I would try to avoid it. I would ask a family member or friend to step in to work it out with them. Ask them to walk away and avoid a battle.
Eventually these guys will see they made some mistakes and have a loosing case.
Hope someone chimes in with better advise. Because it sucks to have 10,000 lbs of trash and be further behind then when you started ):
Hope you can start posting pics of cars in your new shop soon! (:
