Project news Indianapolis International Airport achieves transparency with glass and steel
“The skylight is shaped like a Pringles chip. We positioned a line of rafters and as you go from east to west, the height of each rafter lowers and then rises again. On the north-south line, the glass rises in the middle. With those two elliptical shapes happening, its Pringles-type shape forms, so it's not simply a flat surface.” —Neil Dunbar, project manager, Novum Structures LLC

The basics: The Indianapolis International Airport's new 1.2 million square-foot passenger terminal building features a circular 200-foot diameter skylight with 780 glass lites and 177 steel rafters. Completed in October 2007, the terminal including parking structure cost a total of $1.1 billion and the skylight is valued at $5.5 million.
The players: Architect and designer, Novum Structures LLC, Menomonee Falls, Wis.; construction managers, Indianapolis Airport Authority, Indianapolis, with Hunt/Smoot Midfield Builders, a joint venture of Hunt Construction Group, headquartered in Scottsdale, Ariz., and Smoot Construction, Washington, D.C.; glass fabricator, SanXin Glass Technology Co., China; glazing contractor, Novum Structures LLC; System/framing supplier, Novum Structures LLC.
The glass and systems: Surface area of the skylight is 31,420 square feet, overall glass weight 471,300 pounds and each glass piece is about 9 feet by 4 feet 5 inches in size. The skylight features clear laminated insulating glass with a standard low-E coating and three layers: 10-millimeter heat-strengthened clear layer with grey frit pattern to provide a shading coefficient, 60-millimeter air gap for insulation, and two layers of 8-millimeter heat strengthened glass laminated together using a clear polyvinyl butyral interlayer. Supporting the skylight are 42 rows of rafters consisting of 4-inch-by-16-inch steel tubular hollow sections. The longest rafter is 200 feet long and made from five separate rafters spliced together and supported from ring beam plates at the ends and stub columns that sit on top of the main building steel structure. Each row of rafters is coated with three layers of high-performance paint.
