• Southern parking bays are just a bit too small for the Dash 8 to occupy them.
Dash's weren't going to be using these bays when the lines were marked. They're just going to have to re mark them. Damn!
• Catering vans can not drive on the road under the terminal because the roof is too low.
Catering vans use the tarmac road behind the aircraft in other places. It's probably safer doing it that way as they have to access the rear of the aircraft so coming from the front of the aircraft past the wings to the rear would be hard. Its easier to give the whole terminal a miss and just drive straight up to the aircraft. Even if you have to use the front doors.
• The low roof in the baggage area may be too low to carry the LD aircraft baggage containers on tugs through there.
Rubbish! I've seen a ULD on the back of a Dolly being driven around under there. They are using it for Intl flights.
• The bays are so close to each other that tanker refuelling cannot be used.
As Tag wrote, thats the same at most other (busier) terminals around the world.
Sorry to let the facts get in the way of a good story!
