I build 80+ homes a year, and need to manage it as one project-i think??? the thing is, i have for example 3 Plumbing contractors to do the rough-in for 15 homes, i can only give them 5 homes each and set Priorities for the homes. so oboviously home #2 can start until #1 is completed. and the same goes for plumbing finishes which have to be linked wt the plumber who did the rough-in. All of plumber's #1 tasks need to be linked not only for each activities but across all houses that plumber starts for me. for example plumber #1 may not be able to do the rough-in on 3 Apple St. because he has to to the finishes on 6 Apple St. There has to be a simple solution to this. its a massive job to link it all manually, or is it? Would it be easier to set it up as 80 projects and share resources from a pool or set it up as one project and link the resources manually between activities and houses? i usually have 40-50 homes under construction at any given time.
