There's several extra signal junctions but these I'm sure can be quoted as an add-on to any existing bid quite straightforwardly (none look complex).
The only major tram change I saw is the relocation of the emergency crossover from the Foot of the Walk to Arthur Street. This is just different, not more.
The jankiest bit of new design I can see is the crossover from the bi-directional to unidirectional lane. It's baaaad and there isn't a better way via the gyratory lanes.
They really need to work a gap into the signal phasing to let bikes cross straight over, even if it means an extra red to briefly wait at the pedestrian crossing.
