Key points to note from my observations are as follows but could be completely wrong:
15 new and existing stands to be served from the new peir.
The terminal will be extended to cover the bus and coach station.
The existing bus and coach station will be shifted slightly south and turned 90 degrees.
The existing eastern pier has staircases down to the stands that project out from the glass frontage. Looks like the glass frontage will be brought forward to increase the width of the pier no doubt to add seating areas.
South stands will be increase in size by extending east and west.
The existing drop off area will have to be relocated while the multi-story car park is built but where to? I would have thought to the back of the short term car park so this work would have to be finished first before work on the new apron is started.
The staff car park will go but where to and will they use part of the multi-story car park?
A new road is shown that links the back of the multi-story car park (the exit?) to the tunnel. The embankment is quite deep by the tunnel entrance so quite a bit of work will be needed to get this new road down to the tunnel.
The fast exit routes off the runway are shown as dotted lines, so does this mean this is not part of the initial expansion?
A route to Century Park has to be safeguarded so does this mean that a tunnel will be built at the same time as work is carried out to the airport? If so who pays for the tunnel?
