Construction is underway of the new Pier D at Dublin airport, which will accommodate 14 aircraft and speed up departure times. Green technology is being used to reduce the concrete apron of the site to pulverized rubble which will then be recycled in the foundations of the 14,000 sqm building. The new pier, which will cater for around ten million passengers a year, should be ready by autumn 2007 and will cost an estimated 120 million to complete.
