Commercial buildings design and specialized services constitute another market where Strudes markes its presence. In particular, Shawnessy Light Rail Transit station in Calgary (Alberta, Canada) and a roof system proposed by Strudes for the Molson Centre (now Bell Centre) located in the heart of downtown Montreal are the reason to be proud of. Both realisation won the highest awards of the industry, confirming Strudes as an important player in the field of structural design.
It has the world’s first ultra-thin-shelled canopy system constructed with the new Ductal® technology and opened the door for architects to create structures that were once unimaginable. The technology called “Ductal®” is Lafarge North America’s ultra-high performance, fiber reinforced concrete (UHPFRC) material that offers superior strength, durability, ductility and aesthetics, while providing highly moldable products with a quality surface. The station consists of twenty-four ultra-thin canopies (5.1 m x 6 m and just 20 mm thick /16′-9″ x 19′-8″ and ¾″ thick), supported on single columns, providing protection from elements while lighting to the platform below. The canopies, curved into two planes, challenged the structural engineer in his design of the canopy shell without reinforcement.
In order to meet the economic challenges of professional hockey ownership, the Montreal Canadiens hockey club replaced the venerable Montreal Forum with a new arena, the Molson Centre, now Bell Centre, located in the heart of downtown Montreal. The selection of a double tier truss system, ( a roof system proposed by STRUDES Inc. ) provided the required stiffness, with an unobstructed technical grid area and a reduction of steel weight, resulting in substantial savings over the original proposal. The arena roof is oval in plan, spanning 133.6m x 98.2m to thirty-six peripheral reinforced concrete columns. In addition to the roof deck, snow loading and mechanical and electrical building services, the roof structure also supports a system of walkways, the press gallery and most significantly, a 400 tonne technical floor grid for theatrical prop support, and the Jumbotron central scoreboard. The system was awarded a Prize of Excellence for Construction in Steel by the Canadian Institute of Steel Construction.
