Award of Excellence Winner
Several blocks of St. Catherine Street, a main commercial artery in downtown Montreal, are undergoing a four-year infrastructure improvement plan. During this renewal, segments of the street will be closed to vehicular traffic, but businesses will remain open. Imago won a City of Montreal competition as a creative means of minimizing the construction process’s negative impacts. The competition sought design solutions for an “innovative urban experience” that would direct the flow of people, reduce construction-related disruptions, and disseminate information about the work and its progress.
An imago is the adult stage of a winged insect. This project features modular, inflatable catenary arches with latticed intermediary members that, like a butterfly’s wing, combine lightness, strength and flexibility. Hinged at the top and anchored to concrete construction fence sections at the bottom, the connectable arch components are width-adjustable. Widened, they enclose construction work on the central roadway. When work shifts to the sidewalks along the perimeter, narrowed arches form a sheltering, vaulted pedestrian corridor that can double as a temporary event space.
The inflatable structures are composed from a recyclable high-resistance polymer, and their structural efficiency makes them easy to move and erect. Some of the diamond-shaped voids in the modules are left open for natural ventilation, while others are filled with translucent historical images that narrate the evolution of St. Catherine Street.
