The scope of the project has been prepared with the assistance of Modern Niagara and PowerHouse Group. The methodology for this project has been decided, but Portage College is willing to consider other equivalent options. We are unable to shut down the building during normal working hours (0800-2100 Daily), therefore, all work will be performed while Staff and Students are in the hallways. There will be opportunity for to discuss further at the Contractor Pre-Bid Meeting.
