I'm currently working on a job that's a JV and it is quiet the process. Trying to coordinate with all these guys isn't easy. And using different software is tough, we chose to use Procore for our bidding and drawings. We have it broken out into they do the enclosure and MEP and we do interior finishes. But they keep getting involved in my finishes, like they are scheduling descoping meetings with subs and me. Is that their responsibility even though they aren't touching interiors? I'm pretty new to estimating and wanted to know if people had any advice on working with JVs.
