For EIA we have sculpted a model of the Office and Control Tower at a scale of 1:40. The replica is used on trade shows to promote the Edmonton International Airport. It is build hollow and therefore functions as a draw box. A slit on top of the control tower allows visitors to throw a business card in and participate in a draw. The tower measures 5 feet by 4.5 feet by 3 feet. At a total of 65 cubic feet it weighs a minimum of 9 kg. Which makes handling and set up at multiple trade shows a year very easy and saves shipping costs.
