Harbourside Engineering Consultants are pleased to announce they are the recipient of the 2017 Award of Excellence, presented at the Canadian Consulting Engineering (CCE) Awards gala, for the Burgoyne Bridge Replacement project. The award was presented to HEC and Parsons Corporation at the awards gala in Ottawa, Ontario on October 24 by the Association of Consulting Engineering Companies of Canada and Canadian Consulting Engineering magazine. The CCE Awards, recognized as the industry’s highest honours, are presented to projects by Canadian firms that showcase the most remarkable engineering feats.
The Burgoyne Bridge replacement project consisted of replacing a 100 year old high level truss bridge at the end of its useful life with a signature landmark arch bridge in order to enhance the environment and maintain a key link in the transportation system in the City of St. Catharines. The new structure incorporates twin 333m long steel box girder bridges with a single, central structural steel arch supporting a main span of 125m.
The innovative arch design, incorporating post-tensioning stay systems in all three axes; namely the horizontal tie, the vertical hangers, and a hidden post-tensioned system between the two box girder structures located within each of the transverse floor beams, was developed to facilitate the staging of the project. In order to maintain traffic on the existing bridge during construction, a unique staging plan which involved temporary supports to carry both structure dead load as well as live loads during construction was developed for the project and the permanent design features flowed out of the staging. The result is a bridge which may have a familiar appearance; however, it is at the same time a bridge which possesses a unique structural tie system and behaviour understood to be the first arch bridge of its type in Canada.
