Adapting to Change
In June 2013, the City suffered the largest flood event of its recent history. The St. Patrick’s Bridge was mere months away from completion when excessive water caused the loss of temporary supports under the deck. The team decided to demolish the deck and alter the sequence of construction. ISL and Graham Construction & Engineering collaborated on the redesign of the temporary arch supports and ISL created updated modelling for the erection of the remaining south arches and final load transfer. The work was completed in May 2014.
