thanks for the input guys. When I priced the job I was shown an empty warehouse. Three weeks later when they told me to proceed I show up and there is new equipment on site. I advised them right then that the scope had changed.Also equipment specs were not forthcoming until half way through the job. At least so far I did get the money for my original quote. Original customer and partner both advised of the change in scope and I am working on the tactful approach for the time being.
