With your permission, a Cheann Comhairle, I propose to take Questions Nos. 219 and 220 together.
No doubt the Deputies are referring to demolition work on part of Pier No. 2 and the end of the link building. Pier No. 2 was completed in 1962 and the link building in 1967. They formed part of a long-term development plan for Dublin Airport which also provided for a new terminal building.
Following the announcement in 1966 about Boeing 747 aircraft capable of carrying up to 500 passengers and the placing early in 1967 by Aer Lingus of an order for two of these aircraft, it became necessary to undertake a complete re-appraisal of the long-term development plan.
It emerged after detailed examination of the problems involved with the assistance of expert consultants that a much larger terminal than that originally envisaged was necessary. This building had to be centred on Pier No. 2 to avoid congestion on the apron and land sides of the building. Plans for incorporating existing buildings were considered and it was found that the only other practicable scheme would merely result in the postponement of the demolition work now being carried out and would result ultimately in additional cost of about £270,000.
The portions of the buildings now being demolished, that is less than half of Pier No. 2 and a small portion of the link building, cost approximately £100,000.
The Deputy will appreciate that the rapid pace of technological development in aviation often involves premature obsolesence of aircraft, equipment and buildings. The Boeing 747 is an extreme example of this and is creating problems for airports throughout the world. It has recently been announced for instance that the new terminal building at Schipol completed only two years ago must be modified to handle this aircraft.
The contract for the new terminal building is being managed by Aer Rianta but the approval of my Department was obtained for all stages of the project.
