Macdonald Block Reconstruction

under construction

The Macdonald Block Complex is the administrative hub of Ontario government operations and has a total gross building area of approximately 1.7 million square feet. The complex consists of five buildings: four office towers (Hearst, Hepburn, Mowat and Ferguson Towers) ranging from 10 to 24-storeys, connected by a 2-storey podium (Macdonald Block) with two floors of underground parking. Completed in 1971, the Macdonald Block Complex has never undergone a major renovation. The reconstruction project will update all core building systems, including electrical, water, cooling and heating, which have reached the end of their useful life and must be replaced. It will also update office accommodations to meet modern accessibility standards. Each building in the complex will be taken back to its original building core, remediated and rebuilt using modern technologies, systems and materials while preserving the integrity of its many heritage features. The newly reconstructed complex will meet current building, health, safety, and accessibility standards and will accommodate significantly more employees through more efficient use of this government-owned office space. The project is being delivered through Infrastructure Ontario's design, build, finance and maintain (DBFM) Public-Private Partnership (P3) model, which transfers appropriate risks associated with design, construction, maintenance and financing of the project to the private sector. Infrastructure Ontario and the Ministry of Government and Consumer Services are working together to reconstruct the Macdonald Block Complex, which will continue to be publicly owned.
