General Question problem 01: To what extent can we consider any retrofitting of the existing structure, both for deliverables #2 and #3? Can we add components or strengthen existing ones (eg. column jacking)?

Retrofitting of the existing structure is not permitted for deliverables #2 and #3. This will be one of the primary components of deliverable #4, so it may be beneficial to brainstorm retrofitting options in anticipation of deliverable #4 based on your current analyses.
