Frederickhouse River Bridge

Brown & Co. Engineering Ltd. designed the special equipment and the work sequence required to remove the Fredrickhouse River truss bridge from its piers to permit its demolition on shore. The work required the development of a detailed work plan to identify all temporary support conditions, evaluation of the truss for each of the conditions and strengthening of the truss as required. A critical component of the work was the detailed evaluation of the weight of the existing structure to ensure that sufficient floatation was available and the capacity of all temporary support components were sufficient for the loads. The construction stage design components included a custom lifting frame to lift the truss approximately 4 m, a barge mounted support frame and a rollway mounted on the existing approach spans. This work was presented along with two other sequential de-construction projects at a CSCE conference in 2006.
