Construction costs are still projected to be between $2.8 to $4.6 million and these estimates will be refined as the project proceeds. Based on the completed design plans the project team has revised the construction timeline and the City has asked the Province to extend the substantial completion date to April 15, 2016. The Province still needs to approve the extension.
