Construction is set to begin this month on a 1,045-meter-long bridge over the Mackenzie River near Fort Providence in Canada’s Northwest Territories—a project that required a substantial redesign, adding $18 million to the total cost. The new superstructure design had to be integrated with the original approved substructure design.
An independent design review team of San Francisco-based T.Y. Lin International and Edmonton, Alberta-based BP Tech Engineering found to be substandard the design by Calgary-based Spronken JR and Associates Ltd. The territories’ government terminated the original $169-million construction contract with New Brunswick-based Atcon at the end of 2009, after disputes over construction methods.
