Tri, here is the advice on temporary wood structures we give on our page for MRc7:

It is optional to add temporary wood structures such as sidewalk partitions, bracing, or concrete forms to the baseline wood budget. If added, however, the temporary wood structures can only count toward one project’s certification (that is, if reused on another LEED project, they cannot also count toward MRc7 there). Also, if temporary wood structures are calculated towards the credit compliance, all temporary wood structures need to be counted in the baseline (essentially, you can’t just calculate FSC certified wood structures and not non-FSC certified wood structures).

Unless the temporary structures are FSC-certified wood, it is not generally to your advantage to bring the baseline budget higher by adding them.
