Interview with Gerald Carson - Project architect in charge (Cohos-Evamy Offices)

07.07.2016
 

What were the challenges facing this construction?

The main demand came from the City which wanted a footbridge whose appearance would be a showcase for its innovating concept with regard to bridge building. For a consultant engineer like myself, it meant juggling between the specification and the inflexible demands of the site, the budget and the lead times.

 

The slenderness and the mechanical strength offered by Ductal® enabled us to investigate a wide spectrum of esthetic possibilities that traditional concrete would never have allowed us to consider

How did Ductal® turn out to be the best solution?

Calgary's modernization program was in favor of new materials. The initial objective of the project was to build a footbridge having an attractive profile based on a Tee-shaped beam of Ductal® which could be set into an arch. The slenderness and the mechanical strength offered by Ductal® enabled us to investigate a wide spectrum of esthetic possibilities that traditional concrete would never have allowed us to consider.

What is your commitment to the "Innovative Design Program" developed for the City of Calgary?

As far as I know, we are the only consultant engineering offices to propose an integrated design concept and our own in-house team of architects. We are also working on a second bridge project for the City of Calgary in an identical configuration to that of the Glenmore/Legsby footbridge project.
