EDINBURGH AIRPORT air traffic control tower won the ICE Saltire Society Award for Civil Engineering 2006 on Tuesday.
The award recognises civil engineering excellence in Scotland.
Judges praised the 57m tall tower as a 'very strong presence', which 'enhances the landscape'.
ICE Scotland Manager Derek Elder said: 'Edinburgh Airport air traffic control tower is representative of the great engineering and design talent that we have in Scotland, and which these awards aim to bring to public recognition.' Owned by BAA and operated by National Air Traffic Control Services, the tower was built to meet continuing and predicted growth over the next 25 years.
Architect for the project was Reid Architecture, structural engineer was Arup Scotland and construction was by Laing O'Rourke.
The tower incorporates design features allowing maintenance access without disruption to air traffic control services.
Edinburgh Airport managing director Richard Jeffrey said: 'As well as being exciting and distinctive on a visual level, the tower has enhanced our operation, delivering the extra capacity needed for our ever increasing number of passengers. This is a fantastic achievement and testament to the skills of the design and construction teams involved.'
