Our current project is rapidly evolving into quite a monster. Its a complicated scenario, but I'll try to break it down as best I can.

Our original project is a 4 story office building core and shell project. It has been bid and we are in the early CA shop drawing phase. We are using the same core and shell model inserted into several different ongoing Tenant Improvement (TI) projects. One of the TI projects being explored has the potential to change the core/shell model quite a bit. The owner wants us to explore this process and issue a PR for it, with the understanding that it might not happen. At the same time, normal CA work such as RFI's are being created from the core/shell original model.

Now the question, what is the best way to structure this? The large TI project is changing some major items in the core shell model. What we have done so far (really just starting) is this:

A. Create a copy of the core shell model.

B. The original model is used for CA work and linking into the other TI projects.

C. The second copy is being heavily modified and inserted into the large TI project. We will create the PR from this project.

D. If the PR and major changes are accepted, the revised model now becomes the main model and it is linked into all of the other TI project (and those are adjusted as required). Any CA work done on the original model would need to be redone in the revised model.

E. If the PR is not accepted, then CA work on the original model and its insertion into TI projects continues as normal.

OK, so this sounds like it might work, although it could be tedious to redo the CA changes if the major revisions are accepted. One thought is design options, but the changes could be substantial (revised core locations / configuration, revised structural model, etc) and I'm not sure about setting up options without interupting the ongoing CA process and linking into the other smaller TI projects. Does anyone have any suggestions or advice?

Sounds like a pretty good process you have listed out there.

My question is, where are the smaller TI projects currently as far as construction (or has any construction started?), and how much will this major potential TI revision impact the other smaller TI's?

I would follow your procedure, and if the major TI stuff ends up going ahead, then copy/paste the CA revisions made to the smaller TI revisions that weren't affected by the larger one, and re-make the remaining ones as required.

Tedious, probably, but it will probably be the best in terms of least amount of headaches in getting things to work. Perhaps if the large TI is accepted, you could somehow work the time required to re-do the revisions on the other TI projects into your design fee? ;)
