We are in a unique situation where our client requires deductive alternates that total 20% of the project and a minimum of a LEED Silver certification.
We would like to do a split design and construction review in order to ensure the reviewers agree that we are meeting the intent of the design LEED credits. We tried to create deductive alternates that would have minimal to no implications on some of our major credits. But due to unforeseen conditions we have deductive alternates that vary from material substitutions to a reduction in the building footprint.
Therefore my question is can we submit two versions of the credit for the design review, one for the base bid and one for the deductive alternate?
If so my plan was going to be to document the base bid using the LEED template and upload a summary and back up data that shows compliance for the deductive alternate. Or is there a specific way LEED wants us to document the deductive alternate?

You can't submit two versions for each credit - that would essentially be getting 2 buildings reviewed for the price of one. You should be submitting the final design that was approved to be built, so in your case it might make more sense to do the combined design + construction review. Also remember the combined review is less cost than the split review if you are looking for cost savings.

Agreed, GBCI won't do two reviews on one project. I don't think you can have it both ways.
The final LEED submission is always based on the as-built project. Even in a split submission you will need to state that nothing changed in construction to affect each approved design credit. If you really need to do a split submission I would recommend that you defer any affected design credits to the construction phase or simply wait until the accepted deduct alternates are finalized.
