Sounds like complete rubbish. Just like the rumour about the wrong type of lifts being installed that were not waterproof and that the car park needed a sprinkler system installed because the fire service could not fight a car fire. The fact that it is fully open means it is structurally alright.
The DART is meant to pass to one side of it and not under it as per one rumour that seemed to come from the car park bus drivers.
The ILS issue was fixed last year and the fact that the new multistory will be bigger than the existing seems to dispel that as an issue as well.
Going back to the DART still no real start has been made apart from a few pegs being put into the ground close to Parkway
