The Portage III complex, currently serving as Public Services and Procurement Canada’s headquarters, is the largest of the four buildings that comprise the Place du Portage federal campus in Gatineau, Que. Built in the 1970s, the complex consists of: nine towers; commercial areas; four basement levels; and a three-level underground parking garage. The renewal of Portage III encompasses a complete overhaul of both the inside and outside of the building, including modernized activity-based workplaces; a new energy-efficient building envelope and heating; (HVAC) system; a new accessible entrance and a completely revamped main entrance; and improved landscaping.
