Designed by DIALOG®, a Canadian based architectural firm, the
control tower is situated at the outer edge of a 10,000 square meter office
building, called the COT (Combined Office Tower.) The control tower facade features the metal
“wrap,” which is covered with shingled undulating zinc, and carefully
integrated with the windows to maximize daylight and offer shading when needed.
Each section was sculpted to meet
rigorous viewing requirements set forth by Nav Canada for air traffic
controllers watching the tarmac, runways and skies.
Construction proceeded “air side” or parallel to active
gates at the airport. Radius Track, the curved
framing solutions provider, worked with Thermal Systems KWC Ltd, the building
envelope contractor, and Gehry Technologies, parametric modeling experts, to
design and build the asymmetrical metal ribbon.
The fabrication challenge was to find a way to make the
metal curves smooth, while accommodating the undulating design of the wrap. When Gehry Technologies joined the project
team, they decided to use site surveys instead of the original construction
documents to define the exact location of each truss that would support the
metal ribbon. Working with Radius
Track, they developed a simple solution – a method for curving hat channel –
which provided a smooth attachment surface for the finishing materials.
Prior to fabrication, Radius Track generated a 3D model of
the metal wrap. In the virtual computer
based environment, hat channel and truss locations were set in digital
space. During fabrication, Radius Track
used this information to mark the centerline of each truss attachment location
on the hat channel. The accuracy was so
high that installation crews used the hat channels to place the location of the
trusses. Tyler Weisgerber, Commercial
Division Manager at Thermal System commented that, “the materials used were
significantly more efficient and allowed for a faster and less-complicated
installation with a higher quality result.”
When the new tower opens at the beginning of 2013, it will
stand as an icon - the first and last significant building seen by travelers
visiting the Edmonton International Airport.
The free flowing twists and turns of the building will be enjoyed from
some areas of the terminal, and by those approaching the airport by car. An iconic installation at Canada’s fastest
growing airport, the tower is a distinctive design statement that will be
appreciated by the six million people who travel through each year. “Radius
Track is proud to have been a part of such a distinctive design project,” stated
Chuck Mears, FAIA, and Chief Design Officer of Radius Track.
