Replace signage in the medical school building.

The preference of the committee is that we use a style in keeping with signage installed at UoN over the last decade. This has been done in the main by Signs Direct who's clients were passed to Fusion signs when the owner retired (and closed business). Fusion have already installed sings as part of previous projects in the building (Foyer and B floor), hence if Fusion are used it will avoid the need to replace these 2 portions of the building.
