WE currently have this similar situation in AZ, WI, IL so if I can get answered based on all 3 states... We are the GC. Original contract is for the shell of the building or buildout of original space. The owner has since issued us change orders for the TI (Tenant Improvement of the space) or added another store buildout at the same site. Even though change orders ties to original contract, is this the case for lien purposes? Is each completion their own or as a whole project? Added to this is the fact that additional changes could be for the original contract or the change order of additional TI or buildout.
